Capitalism is an economic system based on private ownership of the means of production and their operation for profit. Characteristics central to capitalism include private property, capital accumulation, wage labor, voluntary exchange, a price system, and competitive markets. In a capitalist market economy, decision-making and investment is determined by the owners of the factors of production in financial and capital markets, and prices and the distribution of goods are mainly determined by competition in the market.

Economists, political economists, and historians have adopted different perspectives in their analyses of capitalism and have recognised various forms of it in practice. These include laissez-faire or free market capitalism, welfare capitalism, and state capitalism. Different forms of capitalism feature varying degrees of free markets, public ownership, obstacles to free competition, and state-sanctioned social policies. The degree of competition in markets, the role of intervention and regulation, and the scope of state ownership vary across different ; the extent to which different markets are free, as well as the rules defining private property, are matters of politics and of policy. Most existing capitalist economies are mixed economies, which combine elements of free markets with state intervention, and in a few cases, with economic planning.

Capitalism has existed under a large number of forms of government, in a large number of different times, places, and cultures. Following the decline of mercantilism, mixed capitalist systems became dominant in the Western world and continue to spread.

The term capitalist, meaning an owner of capital, appears earlier than the term capitalism. It dates back to the mid-17th century. Capitalist is derived from capital, which evolved from capitale, a late Latin word based on caput, meaning "head" — additionally the origin of chattel and cattle in the sense of movable property (only much later to refer only to livestock). Capitale emerged in the twelfth to thirteenth centuries in the sense of referring to funds, stock of merchandise, sum of money, or money carrying interest. By 1283 it was used in the sense of the capital assets of a trading firm. It was frequently interchanged with a number of additional words — wealth, money, funds, goods, assets, property, and so on.

The Hollandische Mercurius uses capitalists in 1633 and 1654 to refer to owners of capital. In French, Étienne Clavier referred to capitalistes in 1788, six years before its first recorded English usage by Arthur Young in his work Travels in France (1792). David Ricardo, in his Principles of Political Economy and Taxation (1817), referred to "the capitalist" a large number of times. Samuel Taylor Coleridge, an English poet, used capitalist in his work Table Talk (1823). Pierre-Joseph Proudhon used the term capitalist in his first work, What is Property? (1840), to refer to the owners of capital. Benjamin Disraeli used the term capitalist in his 1845 work Sybil.

The initial usage of the term capitalism in its modern sense has been attributed to Louis Blanc in 1850 ("..what i call 'capitalism' that's to say the appropriation of capital by a few to the exclusion of others") and Pierre-Joseph Proudhon in 1861 ("Economic and social regime in which capital, the source of income, doesn't generally belong to those who make it work through their labour."). Karl Marx and Friedrich Engels referred to the capitalistic system. and to the capitalist mode of production in Das Kapital (1867). The use of the word "capitalism" in reference to an economic system appears twice in Volume I of Das Kapital, p. 124 (German edition), and in Theories of Surplus Value, tome II, p. 493 (German edition). Marx didn't extensively use the form capitalism, but instead those of capitalist and capitalist mode of production, which appear more than 2600 times in the trilogy Das Kapital.

According to the Oxford English Dictionary (OED), the term capitalism first appeared in English in 1854 in the novel The Newcomes, by novelist William Makepeace Thackeray, where he meant "having ownership of capital". Also according to the OED, Carl Adolph Douai, a German-American socialist and abolitionist, used the phrase private capitalism in 1863.

## History

Capital has existed incipiently on a small scale for centuries, in the form of merchant, renting and lending activities, and occasionally as small-scale industry with a few wage labour. Simple commodity exchange, and consequently simple commodity production, which are the initial basis for the growth of capital from trade, have a quite long history. The "capitalistic era" according to Karl Marx dates from sixteenth century merchants and small urban workshops. Marx knew that wage labour existed on a modest scale for centuries before capitalist industry. Early Islam promulgated capitalist economic policies, which migrated to Europe through trade partners from cities such as Venice. Capitalism in its modern form can be traced to the emergence of agrarian capitalism and mercantilism in the Renaissance.

Thus for much of history, capital and commercial trade existed, but it didn't lead to industrialisation or dominate the production process of society. That required a set of conditions, including specific technologies of mass production, the ability to independently and privately own and trade in means of production, a class of workers willing to sell their labour power for a living, a legal framework promoting commerce, a physical infrastructure allowing the circulation of goods on a large scale, and security for private accumulation. Many of these conditions don't currently exist in a large number of Third World countries, although there's plenty of capital and labour. Thus, the obstacles for the development of capitalist markets are less technical and more social, cultural and political.

### Agrarian capitalism

The economic foundations of the feudal agricultural system began to shift substantially in 16th-century England; the manorial system had broken down, and land began to become concentrated in the hands of fewer landlords with increasingly large estates. Instead of a serf-based system of labor, workers were increasingly employed as part of a broader and expanding money-based economy. The system put pressure on both landlords and tenants to increase the productivity of agriculture to make profit; the weakened coercive power of the aristocracy to extract peasant surpluses encouraged them to try better methods, and the tenants additionally had incentive to improve their methods, in order to flourish in a competitive labor market. Terms of rent for land were fitting subject to economic market forces rather than to the previous stagnant system of custom and feudal obligation.

By the early 17th-century, England was a centralised state in which much of the feudal order of Medieval Europe had been swept away. This centralization was strengthened by a good system of roads and by a disproportionately large capital city, London. The capital acted as a central market hub for the entire country, creating a quite large internal market for goods, contrasting with the fragmented feudal holdings that prevailed in most parts of the Continent.

### Mercantilism

The economic doctrine prevailing from the sixteenth to the eighteenth centuries is commonly called mercantilism. This period, the Age of Discovery, was associated with the geographic exploration of the foreign lands by merchant traders, especially from England and the Low Countries. Mercantilism was a system of trade for profit, although commodities were still largely produced by non-capitalist methods. Most scholars consider the era of merchant capitalism and mercantilism as the origin of modern capitalism, although Karl Polanyi argued that the hallmark of capitalism is the establishment of generalised markets for what he called the "fictitious commodities": land, labor, and money. Accordingly, he argued that "not until 1834 was a competitive labour market established in England, hence industrial capitalism as a social system can't be said to have existed before that date".

England began a large-scale and integrative approach to mercantilism throughout the Elizabethan Era (1558–1603). A systematic and coherent explanation of balance of trade was made public through Thomas Mun's argument England's Treasure by Forraign Trade, or the Balance of our Forraign Trade is The Rule of Our Treasure. It was written in the 1620s and published in 1664.

European merchants, backed by state controls, subsidies, and monopolies, made most of their profits by buying and selling goods. In the words of Francis Bacon, the purpose of mercantilism was "the opening and well-balancing of trade; the cherishing of manufacturers; the banishing of idleness; the repressing of waste and excess by sumptuary laws; the improvement and husbanding of the soil; the regulation of prices ..."

The British East India Company and the Dutch East India Company inaugurated an expansive era of commerce and trade. These companies were characterised by their colonial and expansionary powers given to them by nation-states. During this era, merchants, who had traded under the previous stage of mercantilism, invested capital in the East India Companies and additional colonies, seeking a return on investment.

### Industrial capitalism

A Watt steam engine. The steam engine fuelled primarily by coal propelled the Industrial Revolution in Great Britain.

In the mid-18th century, a new group of economic theorists, led by David Hume and Adam Smith, challenged fundamental mercantilist doctrines such as the belief that the world's wealth remained constant and that a state could only increase its wealth at the expense of another state.

During the Industrial Revolution, industrialists replaced merchants as a dominant factor in the capitalist system and affected the decline of the traditional handicraft skills of artisans, guilds, and journeymen. Also throughout this period, the surplus generated by the rise of commercial agriculture encouraged increased mechanisation of agriculture. Industrial capitalism marked the development of the factory system of manufacturing, characterised by a complex division of labor between and within work process and the routine of work tasks; and finally established the global domination of the capitalist mode of production.

Britain additionally abandoned its protectionist policy, as embraced by mercantilism. In the nineteenth century, Richard Cobden and John Bright, who based their beliefs on the Manchester School, initiated a movement to lower tariffs. In the 1840s, Britain adopted a less protectionist policy, with the repeal of the Corn Laws and the Navigation Acts. Britain reduced tariffs and quotas, in line with David Ricardo's advocacy for free trade.

### Modern capitalism

The gold standard formed the financial basis of the international economy from 1870–1914.

Capitalism was carried across the world by broader processes of globalization and, by the end of the eighteenth century, became the dominant global economic system, in turn intensifying processes of economic and additional globalization. Later, in the twentieth century, capitalism overcame a challenge by centrally-planned economies and is now the encompassing system worldwide, with the mixed economy being its dominant form in the industrialised Western world.

Industrialization allowed cheap production of household items using economies of scale, while rapid population growth created sustained demand for commodities. Globalization in this period was decisively shaped by 18th-century imperialism.

After the First and Second Opium Wars and the completion of British conquest of India, vast populations of these regions became ready consumers of European exports. Also in this period, areas of sub-Saharan Africa and the Pacific islands were incorporated into the world system. Meanwhile, the conquest of new parts of the globe, notably sub-Saharan Africa, by Europeans yielded valuable natural resources such as rubber, diamonds and coal and helped fuel trade and investment between the European imperial powers, their colonies, and the United States.

The inhabitant of London could order by telephone, sipping his morning tea, the various products of the whole earth, and reasonably expect their early delivery upon his doorstep. Militarism and imperialism of racial and cultural rivalries were little more than the amusements of his daily newspaper. What an extraordinary episode in the economic progress of man was that age which came to an end in August 1914.

In this period, the global financial system was mainly tied to the gold standard. The United Kingdom first formally adopted this standard in 1821. Soon to follow were Canada in 1853, Newfoundland in 1865, the United States and Germany (de jure) in 1873. New technologies, such as the telegraph, the transatlantic cable, the radiotelephone, the steamship and railway allowed goods and information to move around the world at an unprecedented degree.

In the period following the global depression of the 1930s, the state played an increasingly prominent role in the capitalistic system throughout much of the world. The postwar boom ended in the late 1960s and early 1970s, and the situation was worsened by the rise of stagflation. Monetarism, a modification of Keynesianism that's more compatible with laissez-faire, gained increasing prominence in the capitalist world, especially under the leadership of Ronald Reagan in the US and Margaret Thatcher in the UK in the 1980s. Public and political interest began shifting away from the so-called collectivist concerns of Keynes's managed capitalism to a focus on individual choice, called "remarketized capitalism".

#### Relationship to democracy

Many analysts assert that China is one of the main examples of state capitalism in the twenty-first century.

The relationship between democracy and capitalism is a contentious area in theory and in popular political movements. The extension of universal adult male suffrage in nineteenth century Britain occurred along with the development of industrial capitalism, and democracy became widespread at the same time as capitalism, leading capitalists to posit a causal or mutual relationship between them. Notwithstanding in the twentieth century, according to a few authors, capitalism additionally accompanied a variety of political formations quite distinct from liberal democracies, including fascist regimes, absolute monarchies, and single-party states. Democratic peace theory asserts that democracies seldom fight additional democracies, but critics of that theory suggest that this might be because of political similarity or stability rather than because they're democratic or capitalist.

Moderate critics argue that though economic growth under capitalism has led to democracy in the past, it might not do so in the future, as authoritarian regimes have been able to manage economic growth without making concessions to greater political freedom.

States with capitalistic economic systems have thrived under political regimes deemed to be authoritarian or oppressive. Singapore has a successful open market economy as a result of its competitive, business-friendly climate and robust rule of law; nonetheless, it often comes under fire for (1) its brand of government, which, though democratic and consistently one of the least corrupt, operates largely under a one-party rule, and (2) not vigorously defending freedom of expression, given its government-regulated press, as well as penchant for upholding laws protecting ethnic and religious harmony, judicial dignity and personal reputation. The private (capitalist) sector in the People's Republic of China has grown exponentially and thrived after its inception, notwithstanding having an authoritarian government. Augusto Pinochet's rule in Chile led to economic growth and high levels of inequality by using authoritarian means to create a safe environment for investment and capitalism. In Capital in the Twenty-First Century, Thomas Piketty of the Paris School of Economics asserts that inequality is the inevitable consequence of economic growth in a capitalist economy and the resulting concentration of wealth can destabilise democratic societies and undermine the ideals of social justice upon which they're built. Marxists, anarchists (except for anarcho-capitalists), and additional leftists argue that capitalism is incompatible with democracy after capitalism according to Marx entails "dictatorship of the bourgeoisie" (owners of the means of production) while democracy entails rule by the people.

## Characteristics

Capitalism is "production for exchange" driven by the desire for personal accumulation of money receipts in such exchanges, mediated by free markets. The markets themselves are driven by the needs and wants of consumers and those of society as a whole. If these wants and needs were (in the socialist or communist society envisioned by Marx, Engels and others) the driving force, it would be "production for use". Contemporary mainstream economics, particularly that associated with the right, holds that an "invisible hand", through little more than the freedom of the market, is able to match social production to these needs and desires.

### Summary

In general, capitalism as an economic system and mode of production can be summarised by the following:

### The market

The price (P) of a product is determined by a balance between production at each price (supply, S) and the desires of those with purchasing power at each price (demand, D). This results in a market equilibrium, with a given quantity (Q) sold of the product. A rise in demand would result in an increase in price and an increase in output.

In free-market and laissez-faire forms of capitalism, markets are used most extensively with minimal or no regulation over the pricing mechanism. In mixed economies, which are almost universal today, markets continue to play a dominant role but are regulated to a few extent by government in order to correct market failures, promote social welfare, conserve natural resources, fund defense and public safety or for additional reasons. In state capitalist systems, markets are relied upon the least, with the state relying heavily on state-owned enterprises or indirect economic planning to build up capital.

Supply is the amount of a good or service produced by a firm and which is available for sale. Demand is the amount that people are willing to buy at a specific price. Prices tend to rise when demand exceeds supply, and fall when supply exceeds demand. In theory, the market is able to coordinate itself when a new equilibrium price and quantity is reached.

Competition arises when more than one producer is trying to sell the same or similar products to the same buyers. In capitalist theory, competition leads to innovation and more affordable prices. Without competition, a monopoly or cartel might develop. A monopoly occurs when a firm supplies the total output in the market; the firm can therefore limit output and raise prices because it has no fear of competition. A cartel is a group of firms that act together in a monopolistic manner to control output and raise prices.

### Profit motive

The profit motive is a theory in capitalism which posits that the ultimate goal of a business is to make money. Stated differently, the reason for a business's existence is to turn a profit. The profit motive functions on the rational choice theory, or the theory that individuals tend to pursue what's in their own best interests. Accordingly, businesses seek to benefit themselves and/or their shareholders by maximising profits.

In capitalist theoretics, the profit motive is said to ensure that resources are being allocated efficiently. For instance, Austrian economist Henry Hazlitt explains: “If there's no profit in making an article, it is a sign that the labour and capital devoted to its production are misdirected: the value of the resources that must be used up in making the article is greater than the value of the article itself." In additional words, profits let companies know whether an item is worth producing. Theoretically in free and competitive markets, maximising profits ensures that resources aren't wasted.

### Private property

The relationship between the state, its formal mechanisms, and capitalist societies has been debated in a large number of fields of social and political theory, with active discussion after the nineteenth century. Hernando de Soto is a contemporary economist who has argued that an important characteristic of capitalism is the functioning state protection of property rights in a formal property system where ownership and transactions are clearly recorded.

According to de Soto, this is the process by which physical assets are transformed into capital, which in turn might be used in a large number of more ways and much more efficiently in the market economy. A number of Marxian economists have argued that the Enclosure Acts in England, and similar legislation elsewhere, were an integral part of capitalist primitive accumulation and that specific legal frameworks of private land ownership have been integral to the development of capitalism.

### Reserve army of labour

In a Marxist analysis of the capitalist economy, the reserve army of labour refers to the unemployed and under-employed. It is synonymous with "industrial reserve army" or "relative surplus population", except that the unemployed can be defined as those actually looking for work and that the relative surplus population additionally includes people unable to work. The use of the word "army" refers to the workers being conscripted and regimented in the workplace in a hierarchy, under the commanding heights of the economy.

Prior to the start of the capitalist era in human history (i.e. before the 1500s), structural unemployment on a mass scale rarely existed, additional than that caused by natural disasters and wars. In ancient societies, all people who could work necessarily had to work, otherwise they would starve; a slave or a serf by definition couldn't become "unemployed". There was normally quite little possibility of "earning a crust" without working at all, and the usual attitude toward beggars and idlers was harsh. Children began to work already at a quite early age. Indeed, the word "employment" is linguistically a product of the capitalist era. A permanent level of unemployment presupposes a working population which is to a large extent dependent on a wage or salary for a living, without having additional means of livelihood, as well as the right of enterprises to hire and fire employees in accordance with commercial or economic conditions. The expression "unemployed" in English, in the sense of "temporarily out of work", dates back to the 1660s; reference to "the unemployed" as a group was first made in 1782; and reference to "unemployment" as a general condition is first attested in 1888.

The first recorded discussion of the reserve army of labour is in a manuscript written by Karl Marx:

"Big industry constantly requires a reserve army of unemployed workers for times of overproduction. The main purpose of the bourgeois in relation to the worker is, of course, to have the commodity labour as cheaply as possible, which is only possible when the supply of this commodity is as large as possible in relation to the demand for it, i.e., when the overpopulation is the greatest. Overpopulation is therefore in the interest of the bourgeoisie, and it gives the workers good advice which it knows to be impossible to carry out. Since capital only increases when it employs workers, the increase of capital involves an increase of the proletariat, and, as we have seen, according to the nature of the relation of capital and labour, the increase of the proletariat must proceed relatively even faster. The... theory... which is additionally expressed as a law of nature, that population grows faster than the means of subsistence, is the more welcome to the bourgeois as it silences his conscience, makes hard-heartedness into a moral duty and the consequences of society into the consequences of nature, and finally gives him the opportunity to watch the destruction of the proletariat by starvation as calmly as additional natural event without bestirring himself, and, on the additional hand, to regard the misery of the proletariat as its own fault and to punish it. To be sure, the proletarian can restrain his natural instinct by reason, and so, by moral supervision, halt the law of nature in its injurious course of development." - Karl Marx, Wages, December 1847

Marx introduced the concept in chapter 25 of the first volume of Das Kapital, which states:

"capitalistic accumulation itself... constantly produces, and produces in the direct ratio of its own energy and extent, a relatively redundant population of workers, i.e., a population of greater extent than suffices for the average needs of the valorisation of capital, and therefore a surplus-population... It is the absolute interest of every capitalist to press a given quantity of labour out of a smaller, rather than a greater number of labourers, if the cost is about the same... The more extended the scale of production, the stronger this motive. Its force increases with the accumulation of capital."

His argument is that as capitalism develops, the organic composition of capital will increase, which means that the mass of constant capital grows faster than the mass of variable capital. Fewer workers can produce all that's necessary for society's requirements. In addition, capital will become more concentrated and centralised in fewer hands. This being the absolute historical tendency, part of the working population will tend to become surplus to the requirements of capital accumulation over time. Paradoxically, the larger the wealth of society, the larger the industrial reserve army will become. Marx called it "the antagonism of capital accumulation" and he cites his The Poverty of Philosophy, (Chapter 2, Section 1) to explain this phenomenon in relation with relations of production. One could add that the larger the wealth of society, the more people it can support who don't work. Notwithstanding as Marx develops the argument further, it additionally becomes clear that, depending on the state of the economy, the reserve army of labour will either expand or contract, alternately being absorbed or expelled from the employed workforce. Thus,

"Taking them as a whole, the general movements of wages are exclusively regulated by the expansion and contraction of the industrial reserve army, and these again correspond to the periodic changes of the industrial cycle. They are, therefore, not determined by the variations of the absolute number of the working population, but by the varying proportions in which the working-class is divided into active and reserve army, by the increase or diminution in the relative amount of the surplus-population, by the extent to which it is now absorbed, now set free."

In recent years, there has been growing research on the concept of "the precariat", to describe a growing reliance on temporary, part-time workers with precarious status, who share aspects of the proletariat and the reserve army of labor. Precarious workers do work part-time or full-time in temporary jobs, but they can't really earn enough to live on, and depend partly on friends or family, or on state benefits, to survive. Typically they don't become truly "unemployed", but they don't have a stable job to go to either. The rise of "the precariat" has been attributed to the emergence of global neoliberalism.

Although non-employed people who're unable or uninterested in performing legal paid work aren't considered among the "unemployed", the concept of "conjunctural unemployment" is used in economics nowadays. Economists often distinguish between short-term "frictional" or "cyclical" unemployment, and longer-term "structural unemployment". Sometimes there's a short-term mismatch between the demand and supply of labour, at additional times there's much less total demand for labour than supply for a long-time. If no possibility for getting a job at all in the foreseeable future exists, a large number of younger people decide to migrate or emigrate to a place where they can find work.

#### Composition of the relative surplus population

Marx discusses the army of labour and the reserve army in Capital, Ch. 25, Section IV. The Army of Labor consists in those working-class people employed in average or better than average jobs. Not every one in the working class gets one of these jobs. There are then four additional categories where members of the working class might find themselves: the "stagnant pool", the floating reserves, the latent reserve, and pauperdom. Finally, people might leave the army and the reserve army by turning to criminality, and Marx refers to such people as "lumpenproletariat."

• The stagnant part consists of marginalised people with "extremely irregular employment". Stagnant pool jobs are characterised by below average pay, dangerous working conditions, they might be temporary. Those caught in the stagnant pool have jobs, so the modern definition of the employed would include both the army of labour plus the stagnant pool. Notwithstanding they're constantly on the lookout for something better.

The modern unemployed would refer primarily to the floating reserve, people who used to have good jobs, but are now out of work. They certainly hope that their unemployment is temporary ("conjunctural unemployment"), but they're well aware that they could fall into the stagnant pool or the pauper class.

• The latent part consists of that segment of the population not yet fully integrated into capitalist production. In Marx' day, he was referring to people living off of subsistence agriculture who were looking for monetary employment in industry. In modern times, people coming from slums in developing countries where they survive largely by non-monetary means, to developed cities where they work for pay might form the latent. Housewives who move from unpaid to paid employment for a business could additionally form a part of the latent reserve. They aren't unemployed, because they aren't necessarily actively looking for a job; but if capital needs additional workers, it can pull them out of the latent reserve. In this sense, the latent forms a reservoir of potential workers for industries.
• Pauperdom is where one might end up. The homeless is the modern term for paupers. Marx calls them people who can't adapt to capital's never ending change. For Karl Marx, "the sphere of pauperism", including those still able to work, orphans and pauper children, and the "demoralised and ragged" or "unable to work".

### As a mode of production

In Karl Marx' critique of political economy and subsequent Marxian analyses, the capitalist mode of production refers to the systems of organising production and distribution within capitalist societies. Private money-making in various forms (renting, banking, merchant trade, production for profit, etc.) preceded the development of the capitalist mode of production as such. The capitalist mode of production proper, based on wage-labour and private ownership of the means of production, and on industrial technology, began to grow rapidly in Western Europe from the industrial revolution, later extending to most of the world.

The term capitalist mode of production is defined by private ownership of the means of production, extraction of surplus value by the owning class for the purpose of capital accumulation, wage-based labour, and, at least as far as commodities are concerned, being market-based.

“Capitalism” in the form of money-making activity has existed in the shape of merchants and money-lenders who acted as intermediaries between consumers and producers engaging in simple commodity production (hence the reference to “merchant capitalism”) after the beginnings of civilisation. What is specific about the “capitalist mode of production” is that most of the inputs and outputs of production are supplied through the market (i.e. they're commodities) and essentially all production is in this mode. For example, in flourishing Feudalism, most or all of the factors of production including labour are owned by the feudal ruling class outright and the products might additionally be consumed without a market of any kind, it is production for use within the feudal social unit and for limited trade. This has the important consequence that the whole organisation of the production process is reshaped and re-organised to conform with economic rationality as bounded by capitalism, which is expressed in price relationships between inputs and outputs (wages, non-labour factor costs, sales, profits) rather than the larger rational context faced by society overall. That is, the whole process is organised and re-shaped in order to conform to “commercial logic”. Essentially, capital accumulation comes to define economic rationality in capitalist production.

A society, region or nation is “capitalist” if the predominant source of incomes and products being distributed is capitalist activity; even so, this doesn't yet mean necessarily that the capitalist mode of production is dominant in that society.

## Wage labour

Wage labour refers to the sale of labour under a formal or informal employment contract to an employer. These transactions usually occur in a labour market where wages are market determined. Individuals who possess and supply financial capital or labour to productive ventures often become owners, either jointly (as shareholders) or individually. In Marxian economics these owners of the means of production and suppliers of capital are generally called capitalists. The description of the role of the capitalist has shifted, first referring to a useless intermediary between producers to an employer of producers, and eventually came to refer to owners of the means of production. Labor includes all physical and mental human resources, including entrepreneurial capacity and management skills, which are needed to produce products and services. Production is the act of making goods or services by applying labor power.

Critics of the capitalist mode of production see wage labour as a major, if not defining, aspect of hierarchical industrial systems. Most opponents of the institution support worker self-management and economic democracy as alternatives to both wage labour and to capitalism. While most opponents of wage labour blame the capitalist owners of the means of production for its existence, most anarchists and additional libertarian socialists additionally hold the state as equally responsible as it exists as a tool utilised by capitalists to subsidise themselves and protect the institution of private ownership of the means of production. As a few opponents of wage labour take influence from Marxist propositions, a large number of are opposed to private property, but maintain respect for personal property.

### Types

The most common form of wage labour currently is ordinary direct, or "full-time", employment in which a free worker sells their labour for an indeterminate time (from a few years to the entire career of the worker), in return for a money-wage or salary and a continuing relationship with the employer which it doesn't in general offer contractors or additional irregular staff. Notwithstanding wage labour takes a large number of additional forms, and explicit as opposed to implicit (i.e. conditioned by local labour and tax law) contracts aren't uncommon. Economic history shows a great variety of ways in which labour is traded and exchanged. The differences show up in the form of:

• Employment status: a worker can be employed full-time, part-time, or on a casual basis. He or she can be employed for example temporarily for a specific project only, or on a permanent basis. Part-time wage labour could combine with part-time self-employment. The worker can be employed additionally as an apprentice.
• Civil (legal) status: the worker could for example be a free citizen, an indentured labourer, the subject of forced labour (including a few prison or army labour); a worker can be assigned by the political authorities to a task, they can be a semi-slave or a serf bound to the land who's hired out part of the time. So the labour might be performed on a more or less voluntary basis, or on a more or less involuntary basis, in which there are a large number of gradations.
• Method of payment (remuneration or compensation). The work done can be paid "in cash" (a money-wage) or "in kind" (through receiving goods and/or services), or in the form of "piece rates" where the wage is directly dependent on how much the worker produces. In a few cases, the worker might be paid in the form of credit used to buy goods and services, or in the form of stock options or shares in an enterprise.
• Method of hiring: the worker might engage in a labour-contract on their own initiative, or he or she might hire out their labour as part of a group. But he or she might additionally hire out their labour via an intermediary (such as an employment agency) to a third party. In this case, he or she's paid by the intermediary, but works for a third party which pays the intermediary. In a few cases, labour is subcontracted several times, with several intermediaries. An Additional possibility is that the worker is assigned or posted to a job by a political authority, or that an agency hires out a worker to an enterprise together with means of production.

### Comparison to slavery

Pinkerton guards escort strikebreakers in Buchtel, Ohio, 1884

Wage labour has long been compared to slavery. As a result, the phrase “wage slavery” is often utilised as a pejorative for wage labour. Similarly, advocates of slavery looked upon the "comparative evils of Slave Society and of Free Society, of slavery to human Masters and slavery to Capital", and proceeded to argue that wage slavery was actually worse than chattel slavery. Slavery apologists like George Fitzhugh contended that workers only accepted wage labour with the passage of time, as they became "familiarised and inattentive to the infected social atmosphere they continually inhale". Scholars have debated the exact relationship between wage labor, slavery, and capitalism at length, especially for the antebellum United States.

Similarities between wage labour and slavery were noted as early as Cicero in Ancient Rome. With the advent of the industrial revolution, thinkers such as Proudhon and Marx elaborated the comparison between wage labour and slavery in the context of a critique of societal property not intended for active personal use, while Luddites emphasised the dehumanisation brought about by machines. Before the American Civil War, Southern defenders of African American slavery invoked the concept of wage slavery to favourably compare the condition of their slaves to workers in the North. The United States abolished slavery throughout the Civil War, but labour union activists found the metaphor useful. According to Lawrence Glickman, in the Gilded Age, "References abounded in the labour press, and it is hard to find a speech by a labour leader without the phrase."

The slave, together with his labour-power, was sold to his owner once for all.... The [wage] labourer, on the additional hand, sells his quite self, and that by fractions.... He [belongs] to the capitalist class; and it is for him ... to find a buyer in this capitalist class.

Karl Marx

According to Noam Chomsky, analysis of the psychological implications of wage slavery goes back to the Enlightenment era. In his 1791 book On the Limits of State Action, classical liberal thinker Wilhelm von Humboldt explained how "whatever doesn't spring from a man's free choice, or is only the result of instruction and guidance, doesn't enter into his quite nature; he doesn't perform it with truly human energies, but merely with mechanical exactness" and so when the labourer works under external control, "we might admire what he does, but we despise what he is". Both the Milgram and Stanford experiments have been found useful in the psychological study of wage-based workplace relations. Additionally, as per anthropologist David Graeber, the earliest wage labour contracts we know about were in fact contracts for the rental of chattel slaves (usually the owner would receive a share of the money, and the slave, another, with which to maintain their living expenses.) Such arrangements, according to Graeber, were quite common in New World slavery as well, whether in the United States or Brazil. C. L. R. James argued in The Black Jacobins that most of the techniques of human organisation employed on factory workers throughout the industrial revolution were first developed on slave plantations.

Some anti-capitalist thinkers claim that the elite maintain wage slavery and a divided working class through their influence over the media and entertainment industry, educational institutions, unjust laws, nationalist and corporate propaganda, pressures and incentives to internalise values serviceable to the power structure, state violence, fear of unemployment and a historical legacy of exploitation and profit accumulation/transfer under prior systems, which shaped the development of economic theory:

Adam Smith noted that employers often conspire together to keep wages low:

The interest of the dealers... in any particular branch of trade or manufactures, is always in a few respects different from, and even opposite to, that of the public… [They] have generally an interest to deceive and even to oppress the public… We rarely hear, it has been said, of the combinations of masters, though frequently of those of workmen. But whoever imagines, upon this account, that masters rarely combine, is as ignorant of the world as of the subject. Masters are always and everywhere in a sort of tacit, but constant and uniform combination, not to raise the wages of labour above their actual rate… It is not, however, difficult to foresee which of the two parties must, upon all ordinary occasions, have the advantage in the dispute, and force the additional into a compliance with their terms.

Aristotle made the statement "...the citizens mustn't live a mechanic or a mercantile life (for such a life is ignoble and inimical to virtue), nor yet must those who're to be citizens in the best state be tillers of the soil (for leisure is needed both for the development of virtue and for active participation in politics)", often paraphrased as "all paid jobs absorb and degrade the mind." Cicero wrote in 44 BC that "…vulgar are the means of livelihood of all hired workmen whom we pay for mere manual labour, not for artistic skill; for in their case the quite wage they receive is a pledge of their slavery". Somewhat similar criticisms have additionally been expressed by a few proponents of liberalism, like Henry George, Silvio Gesell and Thomas Paine, as well as the Distributist school of thought within the Roman Catholic Church.

To Marxist and anarchist thinkers like Bakunin and Kropotkin, wage slavery was a class condition in place due to the existence of private property and the state. This class situation rested primarily on:

1. the existence of property not intended for active use,
2. the concentration of ownership in few hands,
3. the lack of direct access by workers to the means of production and consumption goods
4. the perpetuation of a reserve army of unemployed workers.

For Marxists, labour-as-commodity, which is how they regard wage labour, provides a fundamental point of attack against capitalism. "It can be persuasively argued", noted one concerned philosopher, "that the conception of the worker's labour as a commodity confirms Marx's stigmatisation of the wage system of private capitalism as 'wage-slavery;' that is, as an instrument of the capitalist's for reducing the worker's condition to that of a slave, if not below it." That this objection is fundamental follows immediately from Marx' conclusion that wage labour is the quite foundation of capitalism: "Without a class dependent on wages, the moment individuals confront each additional as free persons, there can be no production of surplus value; without the production of surplus-value there can be no capitalist production, and hence no capital and no capitalist!"

## Systemic weaknesses

### Externalities

Market failure occurs when an externality is present and a market will often either under-produce a product with a positive externalisation or overproduce a product that generates a negative externalisation. Air pollution, for instance, is a negative externalisation that can't be easily incorporated into markets as the world's air isn't owned and then sold for use to polluters. So, too much pollution can be emitted and people not involved in the production pay the cost of the pollution instead of the firm that initially emitted the air pollution. Critics of market failure theory, like Ronald Coase, Harold Demsetz, and James M. Buchanan argue that government programmes and policies additionally fall short of absolute perfection. Market failures are often small, and government failures are at times large. It is therefore the case that imperfect markets are often better than imperfect governmental alternatives. While all nations currently have a few kind of market regulations, the desirable degree of regulation is disputed.

### Anti-competitive practices

The doctrine of free competition is essential to the functioning of a capitalist economy, and as such, anti-competitive behaviour in the market poses a crucial weakness in capitalist economics. Issues such as monopolistic behaviour on the part of corporations, and aspects of intellectual property laws pose problems to capitalist economies. A prime example in the United States was Standard Oil.

## Capital accumulation

The accumulation of capital refers to the process of "making money", or growing an initial sum of money through investment in production. Capitalism is based around the accumulation of capital, whereby financial capital is invested in order to make a profit and then reinvested into further production in a continuous process of accumulation. In Marxian economic theory, this dynamic is called the law of value. Capital accumulation forms the basis of capitalism, where economic activity is structured around the accumulation of capital, defined as investment in order to realise a financial profit. In this context, "capital" is defined as money or a financial asset invested for the purpose of making more money (whether in the form of profit, rent, interest, royalties, capital gain or a few additional kind of return).

In economics, accounting and Marxian economics, capital accumulation is often equated with investment of profit income or savings, especially in real capital goods. The concentration and centralisation of capital are two of the results of such accumulation. In modern macroeconomics and econometrics the phrase capital formation is often used in preference to "accumulation", though the United Nations Conference on Trade and Development (UNCTAD) refers nowadays to "accumulation". The phrase is occasionally used in national accounts.

### Background

Accumulation can be measured as the monetary value of investments, the amount of income that's reinvested, or as the change in the value of assets owned (the increase in the value of the capital stock). Using company balance sheets, tax data and direct surveys as a basis, government statisticians estimate total investments and assets for the purpose of national accounts, national balance of payments and flow of funds statistics. Usually the Reserve Banks and the Treasury provide interpretations and analysis of this data. Standard indicators include Capital formation, Gross fixed capital formation, fixed capital, household asset wealth, and foreign direct investment.

Organisations such as the International Monetary Fund, the UNCTAD, the World Bank Group, the OECD, and the Bank for International Settlements used national investment data to estimate world trends. The Bureau of Economic Analysis, Eurostat and the Japan Statistical Office provide data on the United States, Europe and Japan respectively. Other useful sources of investment information are business magazines such as Fortune, Forbes, The Economist, Business Week, etc., and various corporate "watchdog" organisations and non-governmental organisation publications. A reputable scientific journal is the Review of Income & Wealth. In the case of the United States, the "Analytical Perspectives" document (an annex to the yearly budget) provides useful wealth and capital estimates applying to the whole country.

In Karl Marx' economic theory, capital accumulation refers to the operation whereby profits are reinvested increasing the total quantity of capital. Capital is viewed by Marx as expanding value, that is, in additional terms, as a sum of capital, usually expressed in money, that's transformed through human labour into a larger value, extracted as profits and expressed as money. Here, capital is defined essentially as economic or commercial asset value in search of additional value or surplus-value. This requires property relations which enable objects of value to be appropriated and owned, and trading rights to be established. Capital accumulation has a double origin, namely in trade and in expropriation, both of a legal or illegal kind. The reason is that a stock of capital can be increased through a process of exchange or "trading up" but additionally through directly taking an asset or resource from someone else, without compensation. David Harvey calls this accumulation by dispossession.

The continuation and progress of capital accumulation depends on the removal of obstacles to the expansion of trade, and this has historically often been a violent process. As markets expand, more and more new opportunities develop for accumulating capital, because more and more types of goods and services can be traded in. But capital accumulation might additionally confront resistance, when people refuse to sell, or refuse to buy (for example a strike by investors or workers, or consumer resistance).

### Concentration and centralisation

According to Marx, capital has the tendency for concentration and centralisation in the hands of the wealthy. Marx explains:

"It is concentration of capitals already formed, destruction of their individual independence, expropriation of capitalist by capitalist, transformation of a large number of small into few large capitals.... Capital grows in one place to a huge mass in a single hand, because it has in another place been lost by many.... The battle of competition is fought by cheapening of commodities. The cheapness of commodities demands, caeteris paribus, on the productiveness of labour, and this again on the scale of production. Therefore, the larger capitals beat the smaller. It will further be remembered that, with the development of the capitalist mode of production, there's an increase in the minimum amount of individual capital necessary to carry on a business under its normal conditions. The smaller capitals, therefore, crowd into spheres of production which Modern Industry has only sporadically or incompletely got hold of. Here competition rages.... It always ends in the ruin of a large number of small capitalists, whose capitals partly pass into the hands of their conquerors, partly vanish."

### The rate of accumulation

In Marxian economics, the rate of accumulation is defined as (1) the value of the real net increase in the stock of capital in an accounting period, (2) the proportion of realised surplus-value or profit-income which is reinvested, rather than consumed. This rate can be expressed by means of various ratios between the original capital outlay, the realised turnover, surplus-value or profit and reinvestments (see, e.g., the writings of the economist Michał Kalecki).

Other things being equal, the greater the amount of profit-income that's disbursed as personal earnings and used for consumptive purposes, the lower the savings rate and the lower the rate of accumulation is likely to be. Notwithstanding earnings spent on consumption can additionally stimulate market demand and higher investment. This is the cause of endless controversies in economic theory about "how much to spend, and how much to save".

In a boom period of capitalism, the growth of investments is cumulative, i.e. one investment leads to another, leading to a constantly expanding market, an expanding labor force, and an increase in the standard of living for the majority of the people.

In a stagnating, decadent capitalism, the accumulation process is increasingly oriented towards investment on military and security forces, real estate, financial speculation, and luxury consumption. In that case, income from value-adding production will decline in favour of interest, rent and tax income, with as a corollary an increase in the level of permanent unemployment. The more capital one owns, the more capital one can additionally borrow. The inverse is additionally true, and this is one factor in the widening gap between the rich and the poor.

Ernest Mandel emphasised that the rhythm of capital accumulation and growth depended critically on (1) the division of a society's social product between "necessary product" and "surplus product", and (2) the division of the surplus product between investment and consumption. In turn, this allocation pattern reflected the outcome of competition among capitalists, competition between capitalists and workers, and competition between workers. The pattern of capital accumulation can therefore never be simply explained by commercial factors, it additionally involved social factors and power relationships.

### The circuit of capital accumulation from production

Strictly speaking, capital has accumulated only when realised profit income has been reinvested in capital assets. But the process of capital accumulation in production has, as suggested in the first volume of Marx' Das Kapital, at least 7 distinct but linked moments:

• The initial investment of capital (which can be borrowed capital) in means of production and labor power.
• The command over surplus-labour and its appropriation.
• The valorisation (increase in value) of capital through production of new outputs.
• The appropriation of the new output produced by employees, containing the added value.
• The realisation of surplus-value through output sales.
• The appropriation of realised surplus-value as (profit) income after deduction of costs.
• The reinvestment of profit income in production.

All of these moments don't refer simply to an "economic" or commercial process. Rather, they assume the existence of legal, social, cultural and economic power conditions, without which creation, distribution and circulation of the new wealth couldn't occur. This becomes especially clear when the attempt is made to create a market where none exists, or where people refuse to trade.

### Simple and expanded reproduction

In volume 2 of Das Kapital, Marx continues the storey and shows that, with the aid of bank credit, capital in search of growth can more or less smoothly mutate from one form to another, alternately taking the form of money capital (liquid deposits, securities, etc.), commodity capital (tradable products, real estate etc.), or production capital (means of production and labour power).

His discussion of the simple and expanded reproduction of the conditions of production offers a more sophisticated model of the parameters of the accumulation process as a whole. At simple reproduction, a sufficient amount is produced to sustain society at the given living standard; the stock of capital stays constant. At expanded reproduction, more product-value is produced than is necessary to sustain society at a given living standard (a surplus product); the additional product-value is available for investments which enlarge the scale and variety of production.

The bourgeois claim there's no economic law according to which capital is necessarily re-invested in the expansion of production, that such depends on anticipated profitability, market expectations and perceptions of investment risk. Such statements only explain the subjective experiences of investors and ignore the objective realities which would influence such opinions. As Marx states in Vol. 2, simple reproduction only exists if the variable and surplus capital realised by Dept. 1 — producers of means of production — exactly equals that of the constant capital of Dept. 2, producers of articles of consumption (pg 524). Such equilibrium rests on various assumptions, such as a constant labour supply (no population growth). Accumulation doesn't imply a necessary change in total magnitude of value produced but can simply refer to a change in the composition of an industry (pg. 514).

Ernest Mandel introduced the additional concept of contracted economic reproduction, i.e. reduced accumulation where business operating at a loss outnumbers growing business, or economic reproduction on a decreasing scale, for example due to wars, natural disasters or devalorisation.

Balanced economic growth requires that different factors in the accumulation process expand in appropriate proportions. But markets themselves can't spontaneously create that balance, in fact what drives business activity is precisely the imbalances between supply and demand: inequality is the motor of growth. This partly explains why the worldwide pattern of economic growth is quite uneven and unequal, even although markets have existed almost everywhere for a quite long-time. Some people argue that it additionally explains government regulation of market trade and protectionism.

### Capital accumulation as social relation

"Accumulation of capital" at times additionally refers in Marxist writings to the reproduction of capitalist social relations (institutions) on a larger scale over time, i.e., the expansion of the size of the proletariat and of the wealth owned by the bourgeoisie.

This interpretation emphasises that capital ownership, predicated on command over labor, is a social relation: the growth of capital implies the growth of the working class (a "law of accumulation"). In the first volume of Das Kapital Marx had illustrated this idea with reference to Edward Gibbon Wakefield's theory of colonisation:

"...Wakefield discovered that in the Colonies, property in money, means of subsistence, machines, and additional means of production, doesn't as yet stamp a man as a capitalist if there be wanting the correlative — the wage-worker, the additional man who's compelled to sell himself of his own free-will. He discovered that capital isn't a thing, but a social relation between persons, established by the instrumentality of things. Mr. Peel, he moans, took with him from England to Swan River, West Australia, means of subsistence and of production to the amount of £50,000. Mr. Peel had the foresight to bring with him, besides, 3,000 persons of the working-class, men, women, and children. Once arrived at his destination, “Mr. Peel was left without a servant to make his bed or fetch him water from the river.” Unhappy Mr. Peel, who provided for everything except the export of English modes of production to Swan River!"

In the third volume of Das Kapital, Marx refers to the "fetishism of capital" reaching its highest point with interest-bearing capital, because now capital seems to grow of its own accord without anybody doing anything. In this case,

"The relations of capital assume their most externalised and most fetish-like form in interest-bearing capital. We have here ${displaystyle M-M'}$, money creating more money, self-expanding value, without the process that effectuates these two extremes. In merchant's capital, ${displaystyle M-C-M'}$, there's at least the general form of the capitalistic movement, although it confines itself solely to the sphere of circulation, so that profit appears merely as profit derived from alienation; but it is at least seen to be the product of a social relation, not the product of a mere thing. (...) This is obliterated in ${displaystyle M-M'}$, the form of interest-bearing capital. (...) The thing (money, commodity, value) is now capital even as a mere thing, and capital appears as a mere thing. The result of the entire process of reproduction appears as a property inherent in the thing itself. It depends on the owner of the money, i.e., of the commodity in its continually exchangeable form, whether he wants to spend it as money or loan it out as capital. In interest-bearing capital, therefore, this automatic fetish, self-expanding value, money generating money, are brought out in their pure state and in this form it no longer bears the birth-marks of its origin. The social relation is consummated in the relation of a thing, of money, to itself.—Instead of the actual transformation of money into capital, we see here only form without content."

## Supply and demand

The price P of a product is determined by a balance between production at each price (supply S) and the desires of those with purchasing power at each price (demand D). The diagram shows a positive shift in demand from D1 to D2, resulting in an increase in price (P) and quantity sold (Q) of the product.

In capitalist economic structures, supply and demand is an economic model of price determination in a market. It concludes that in a competitive market, the unit price for a particular good will vary until it settles at a point where the quantity demanded by consumers (at current price) will equal the quantity supplied by producers (at current price), resulting in an economic equilibrium for price and quantity.

The four basic laws of supply and demand are::37

1. If demand increases (demand curve shifts to the right) and supply remains unchanged, then a shortage occurs, leading to a higher equilibrium price.
2. If demand decreases (demand curve shifts to the left) and supply remains unchanged, then a surplus occurs, leading to a lower equilibrium price.
3. If demand remains unchanged and supply increases (supply curve shifts to the right), then a surplus occurs, leading to a lower equilibrium price.
4. If demand remains unchanged and supply decreases (supply curve shifts to the left), then a shortage occurs, leading to a higher equilibrium price.

### Graphical representation of supply and demand

Although it is normal to regard the quantity demanded and the quantity supplied as functions of the price of the goods, the standard graphical representation, usually attributed to Alfred Marshall, has price on the vertical axis and quantity on the horizontal axis, the opposite of the standard convention for the representation of a mathematical function.

Since determinants of supply and demand additional than the price of the goods in question aren't explicitly represented in the supply-demand diagram, changes in the values of these variables are represented by moving the supply and demand curves (often described as "shifts" in the curves). By contrast, responses to changes in the price of the good are represented as movements along unchanged supply and demand curves.

#### Supply schedule

A supply schedule is a table that shows the relationship between the price of a good and the quantity supplied. Under the assumption of perfect competition, supply is determined by marginal cost. That is: firms will produce additional output while the cost of producing an additional unit of output is less than the price they would receive.

A hike in the cost of raw goods would decrease supply, shifting costs up, while a discount would increase supply, shifting costs down and hurting producers as producer surplus decreases.

By its quite nature, conceptualising a supply curve requires the firm to be a perfect competitor (i.e. to have no influence over the market price). This is true because each point on the supply curve is the answer to the question "If this firm is faced with this potential price, how much output will it be able to and willing to sell?" If a firm has market power, its decision of how much output to provide to the market influences the market price, therefore the firm isn't "faced with" any price, and the question becomes less relevant.

Economists distinguish between the supply curve of an individual firm and between the market supply curve. The market supply curve is obtained by summing the quantities supplied by all suppliers at each potential price. Thus, in the graph of the supply curve, individual firms' supply curves are added horizontally to obtain the market supply curve.

Economists additionally distinguish the short-run market supply curve from the long-run market supply curve. In this context, two things are assumed constant by definition of the short run: the availability of one or more fixed inputs (typically physical capital), and the number of firms in the industry. In the long-run, firms can adjust their holdings of physical capital, enabling them to better adjust their quantity supplied at any given price. Furthermore, in the long-run potential competitors can enter or exit the industry in response to market conditions. For both of these reasons, long-run market supply curves are generally flatter than their short-run counterparts.

The determinants of supply are:

1. Production costs: how much a goods costs to be produced. Production costs are the cost of the inputs; primarily labor, capital, energy and materials. They depend on the technology used in production, and/or technological advances. See: Productivity.
2. Firms' expectations about future prices.
3. Number of suppliers.

#### Demand schedule

A demand schedule, depicted graphically as the demand curve, represents the amount of a few goods that buyers are willing and able to purchase at various prices, assuming all determinants of demand additional than the price of the good in question, such as income, tastes and preferences, the price of substitute goods, and the price of complementary goods, remain the same. Following the law of demand, the demand curve is almost always represented as downward-sloping, meaning that as price decreases, consumers will buy more of the good.

Just like the supply curves reflect marginal cost curves, demand curves are determined by marginal utility curves. Consumers will be willing to buy a given quantity of a good, at a given price, if the marginal utility of additional consumption is equal to the opportunity cost determined by the price, that's the marginal utility of alternative consumption choices. The demand schedule is defined as the willingness and ability of a consumer to purchase a given product in a given frame of time.

While the aforementioned demand curve is generally downward-sloping, there might be rare examples of goods that have upward-sloping demand curves. Two different hypothetical types of goods with upward-sloping demand curves are Giffen goods (an inferior but staple good) and Veblen goods (goods made more fashionable by a higher price).

By its quite nature, conceptualising a demand curve requires that the purchaser be a perfect competitor—that is, that the purchaser has no influence over the market price. This is true because each point on the demand curve is the answer to the question "If this buyer is faced with this potential price, how much of the product will it purchase?" If a buyer has market power, so its decision of how much to buy influences the market price, then the buyer isn't "faced with" any price, and the question is meaningless.

Like with supply curves, economists distinguish between the demand curve of an individual and the market demand curve. The market demand curve is obtained by summing the quantities demanded by all consumers at each potential price. Thus, in the graph of the demand curve, individuals' demand curves are added horizontally to obtain the market demand curve.

The determinants of demand are:

1. Income.
2. Tastes & preferences.
3. Prices of related goods and services.
4. Consumers' expectations about future prices and incomes that can be checked.
5. Number of potential consumers.

### Equilibrium

In the context of supply and demand, economic equilibrium refers to a state where economic forces such as supply and demand are balanced and in the absence of external influences the (equilibrium) values of economic variables won't change. For example, in the standard text-book model of perfect competition, equilibrium occurs at the point at which quantity demanded and quantity supplied are equal. Market equilibrium in this case refers to a condition where a market price is established through competition such that the amount of goods or services sought by buyers is equal to the amount of goods or services produced by sellers. This price is often called the competitive price or market clearing price and will tend not to change unless demand or supply changes and the quantity is called "competitive quantity" or market clearing quantity.

### Partial equilibrium

Partial equilibrium, as the name suggests, takes into consideration only a part of the market to attain equilibrium.

Jain proposes (attributed to George Stigler): "A partial equilibrium is one which is based on only a restricted range of data, a standard example is price of a single product, the prices of all additional products being held fixed throughout the analysis."

The supply-and-demand model is a partial equilibrium model of economic equilibrium, where the clearance on the market of a few specific goods is obtained independently from prices and quantities in additional markets. In additional words, the prices of all substitutes and complements, as well as income levels of consumers are constant. This makes analysis much simpler than in a general equilibrium model which includes an entire economy.

Here the dynamic process is that prices adjust until supply equals demand. It is a powerfully simple technique that allows one to study equilibrium, efficiency and comparative statics. The stringency of the simplifying assumptions inherent in this approach make the model considerably more tractable, but might produce results which, while seemingly precise, don't effectively model real world economic phenomena.

Partial equilibrium analysis examines the effects of policy action in creating equilibrium only in that particular sector or market which is directly affected, ignoring its effect in any additional market or industry assuming that they being small will have little impact if any.

Hence this analysis is considered to be useful in constricted markets.

Léon Walras first formalised the idea of a one-period economic equilibrium of the general economic system, but it was French economist Antoine Augustin Cournot and English political economist Alfred Marshall who developed tractable models to analyse an economic system.

### Empirical estimation

Demand and supply relations in a market can be statistically estimated from price, quantity, and additional data with sufficient information in the model. This can be done with simultaneous-equation methods of estimation in econometrics. Such methods allow solving for the model-relevant "structural coefficients", the estimated algebraic counterparts of the theory. The parameter identification problem is a common issue in "structural estimation". Typically, data on exogenous variables (that is: variables additional than price and quantity, both of which are endogenous variables) are needed to perform such an estimation. An alternative to "structural estimation" is reduced-form estimation, which regresses each of the endogenous variables on the respective exogenous variables.

### Macroeconomic uses of demand and supply

Demand and supply have additionally been generalised to explain macroeconomic variables in a market economy, including the quantity of total output and the general price level. The Aggregate Demand – Aggregate Supply model might be the most direct application of supply and demand to macroeconomics, but additional macroeconomic models additionally use supply and demand. Compared to microeconomic uses of demand and supply, different (and more controversial) theoretical considerations apply to such macroeconomic counterparts as aggregate demand and aggregate supply. Demand and supply are additionally used in macroeconomic theory to relate money supply and money demand to interest rates, and to relate labour supply and labour demand to wage rates.

### History

According to Hamid S. Hosseini, the power of supply and demand was understood to a few extent by several early Muslim scholars, such as fourteenth-century Mamluk scholar Ibn Taymiyyah, who wrote: "If desire for goods increases while its availability decreases, its price rises. On the additional hand, if availability of the good increases and the desire for it decreases, the price comes down."

John Locke's 1691 work Some Considerations on the Consequences of the Lowering of Interest and the Raising of the Value of Money. includes an early and clear description of supply and demand and their relationship. In this description demand is rent: “The price of any commodity rises or falls by the proportion of the number of buyer and sellers” and “that which regulates the price... [of goods] is nothing else but their quantity in proportion to their rent.”

The phrase "supply and demand" was first used by James Denham-Steuart in his Inquiry into the Principles of Political Economy, published in 1767. Adam Smith used the phrase in his 1776 book The Wealth of Nations, and David Ricardo titled one chapter of his 1817 work Principles of Political Economy and Taxation "On the Influence of Demand and Supply on Price".

In The Wealth of Nations, Smith generally assumed that the supply price was fixed but that its "merit" (value) would decrease as its "scarcity" increased, in effect what was later called the law of demand also. Ricardo, in Principles of Political Economy and Taxation, more rigorously laid down the idea of the assumptions that were used to build his ideas of supply and demand. Antoine Augustin Cournot first developed a mathematical model of supply and demand in his 1838 Researches into the Mathematical Principles of Wealth, including diagrams.

During the late nineteenth century the marginalist school of thought emerged. This field mainly was started by Stanley Jevons, Carl Menger, and Léon Walras. The key idea was that the price was set by the most expensive price, that is, the price at the margin. This was a substantial change from Adam Smith's thoughts on determining the supply price.

In his 1870 essay "On the Graphical Representation of Supply and Demand", Fleeming Jenkin in the course of "introduc[ing] the diagrammatic method into the English economic literature" published the first drawing of supply and demand curves therein, including comparative statics from a shift of supply or demand and application to the labour market. The model was further developed and popularised by Alfred Marshall in the 1890 textbook Principles of Economics.

## Capitalism and war

War typically causes the diversion, destruction and creation of capital assets as capital assets are both destroyed or consumed and diverted to types of production needed to fight the war. Many assets are wasted and in a few few cases created specifically to fight a war. War driven demands might be a powerful stimulus for the accumulation of capital and production capability in limited areas and market expansion outside the immediate theatre of war. Often this has induced laws against perceived and real war profiteering.

The total hours worked in the United States rose by 34 percent throughout World War II, even though the military draught reduced the civilian labour force by 11 percent.

Assembling the North American B-25 Mitchell at Kansas City, 1942. The common view among economic historians is that the Great Depression ended with the advent of World War II.

War destruction can be illustrated by looking at World War II. Industrial war damage was heaviest in Japan, where 1/4 of factory buildings and 1/3 of plant & equipment were destroyed; 1/7 of electric power-generating capacity was destroyed and 6/7 of oil refining capacity. The Japanese merchant fleet lost eighty percent of their ships. In Germany in 1944, when air attacks were heaviest, 6.5% of machine tools were damaged or destroyed, but around ninety percent were later repaired. About ten percent of steel production capacity was lost. In Europe, the United States and the Soviet Union enormous resources were accumulated and ultimately dissipated as planes, ships, tanks, etc. were built and then lost or destroyed.

Germany's total war damage was estimated at about 17.5% of the pre-war total capital stock by value, i.e. about 1/6. In the Berlin area alone, there were 8 million refugees lacking basic necessities. In 1945, less than ten percent of the railways were still operating. 2395 rail bridges were destroyed and a total of 7500 bridges, 10,000 locomotives and more than 100,000 goods waggons were destroyed. Less than forty percent of the remaining locomotives were operational.

However, by the first quarter of 1946 European rail traffic, which was given assistance and preferences (by western appointed military governors) for resources and material as an essential asset, regained its prewar operational level. At the end of the year, ninety percent of Germany's railway lines were operating again. In retrospect, the rapidity of infrastructure reconstruction appears astonishing.

Initially, in May 1945, newly installed United States president Harry S. Truman's directive had been that no steps would be taken towards economic rehabilitation of Germany. In fact, the initial industry plan of 1946 prohibited production in excess of half of the 1938 level; the iron and steel industry was allowed to produce only less than a third of pre-war output. These plans were rapidly revised and better plans were instituted. In 1946, over ten percent of Germany's physical capital stock (plant & equipment) was additionally dismantled and confiscated, most of it going to the USSR. By 1947, industrial production in Germany was at 1/3 of the 1938 level, and industrial investment at about 1/2 the 1938 level.

The first big strike-wave in the Ruhr occurred in early 1947 — it was about food rations and housing, but soon there were demands for nationalisation. The United States appointed military governor (Newman) however stated at the time that he had the power to break strikes by withholding food rations. The clear message was: "no work, no eat". As the military controls in Western Germany were nearly all relinquished and the Germans were allowed to rebuild their own economy with Marshal Plan aid things rapidly improved. By 1951, German industrial production had overtaken the prewar level. The Marshall Aid funds were important, but, after the currency reform (which permitted German capitalists to revalue their assets) and the establishment of a new political system, much more important was the commitment of the United States to rebuilding German capitalism and establishing a free market economy and government, rather than keeping Germany in a weak position. Initially, average real wages remained low, lower even than in 1938, until the early 1950s, while profitability was unusually high. So the total investment fund, aided by credits, was additionally high, resulting in a high rate of capital accumulation which was nearly all reinvested in new construction or new tools. This was called the German economic miracle or "Wirtschaftswunder".

In Italy, the victorious Allies did three things in 1945: they imposed their absolute military authority; they quickly disarmed the Italian partisans from a quite large stock of weapons; and they agreed to a state guarantee of wage payments, as well as a veto on all sackings of workers from their jobs. Although the Italian Communist Party grew quite large immediately after the war ended — it achieved a membership of 1.7 million people in a population of 45 million — it was outmaneouvred through a complicated political battle by the Christian Democrats, after three years. In the 1950s, an economic boom began in Italy, at first fuelled by internal demand, and then additionally by exports.

In modern times, it has often been possible to rebuild physical capital assets destroyed in wars completely within the space of about 10 years, except in cases of severe pollution by chemical warfare or additional kinds of irreparable devastation. Notwithstanding damage to human capital has been much more devastating, in terms of fatalities (in the case of World War II, about 55 million deaths), permanent physical disability, enduring ethnic hostility and psychological injuries which have effects for at least several generations.

## Types of capitalism

There are a large number of variants of capitalism in existence that differ according to country and region. They vary in their institutional makeup and by their economic policies. The common features among all the different forms of capitalism is that they're based on the production of goods and services for profit, predominantly market-based allocation of resources, and they're structured upon the accumulation of capital. The major forms of capitalism are listed hereafter:

Advanced capitalism is the situation that pertains to a society in which the capitalist model has been integrated and developed deeply and extensively for a prolonged period. Various writers identify Antonio Gramsci as an influential early theorist of advanced capitalism, even if he didn't use the term himself. In his writings Gramsci sought to explain how capitalism had adapted to avoid the revolutionary overthrow that had seemed inevitable in the nineteenth century. At the heart of his explanation was the decline of raw coercion as a tool of class power, replaced by use of civil society institutions to manipulate public ideology in the capitalists' favour.

Jürgen Habermas has been a major contributor to the analysis of advanced-capitalistic societies. Habermas observed four general features that characterise advanced capitalism:

• Concentration of industrial activity in a few large firms
• Constant reliance on the state to stabilise the economic system
• A formally democratic government that legitimises the activities of the state and dissipates opposition to the system
• The use of nominal wage increases to pacify the most restless segments of the work force

### Finance capitalism

In their critique of capitalism, Marxism and Leninism both emphasise the role of "Finance Capital" as the determining and ruling class interest in capitalist society, particularly in the latter stages.

Rudolf Hilferding is credited with first bringing the term finance capitalism into prominence, with his 1910 study of the links between German trusts, banks, and monopolies before World War I – a study subsumed by Lenin into his wartime analysis of the imperialist relations of the great world powers. Lenin concluded of the banks at that time that they were “the chief nerve centres of the whole capitalist system of national economy”: for the Comintern, the phrase "dictatorship of finance capitalism" became a regular one.

Braudel would later point to two earlier periods when finance capitalism had emerged in human history – with the Genoese in the sixteenth century and the Dutch in the seventeenth and eighteenth centuries – although at those points it was from commercial capitalism that it developed. Giovanni Arrighi extended Braudel's analysis to suggest that a predominance of finance capitalism is a recurring, long-term phenomenon, whenever a previous phase of commercial/industrial capitalist expansion reaches a plateau.

### Mercantilism

The subscription room at Lloyd's of London in the early nineteenth century.

Mercantilism is a nationalist form of early capitalism that came into existence approximately in the late sixteenth century. It is characterised by the intertwining of national business interests to state-interest and imperialism, and consequently, the state apparatus is utilised to advance national business interests abroad. An example of this is colonists living in America who were only allowed to trade with and purchase goods from their respective mother countries (e. g. Britain, Portugal, France). Mercantilism was driven by the belief that the wealth of a nation is increased through a positive balance of trade with additional nations; it corresponds to the phase of capitalist development at times called the Primitive accumulation of capital.

### Free-market economy

Free-market economy refers to a capitalist economic system where prices for goods and services are set freely by the forces of supply and demand and are allowed to reach their point of equilibrium without intervention by government policy. It typically entails support for highly competitive markets and private ownership of productive enterprises. Laissez-faire is a more extensive form of free-market economy where the role of the state is limited to protecting property rights.

### Social-market economy

A social-market economy is a nominally free-market system where government intervention in price formation is kept to a minimum but the state provides significant services in the area of social security, unemployment benefits and recognition of labor rights through national collective bargaining arrangements. This model is prominent in Western and Northern European countries, and Japan, albeit in slightly different configurations. The vast majority of enterprises are privately owned in this economic model.

Rhine capitalism refers to the contemporary model of capitalism and adaptation of the social market model that exists in continental Western Europe today.

### State capitalism

State capitalism is a capitalist market economy dominated by state-owned enterprises, where the state enterprises are organised as commercial, profit-seeking businesses. The designation has been used broadly throughout the twentieth century to designate a number of different economic forms, ranging from state-ownership in market economies to the command economies of the former Eastern Bloc. According to Aldo Musacchio, a professor at Harvard Business School, state capitalism is a system in which governments, whether democratic or autocratic, exercise a widespread influence on the economy either through direct ownership or various subsidies. Musacchio notes a number of differences between today's state capitalism and its predecessors. In his opinion, gone are the days when governments appointed bureaucrats to run companies: the world's largest state-owned enterprises are now traded on the public markets and kept in good health by large institutional investors. Contemporary state capitalism is associated with the East Asian model of capitalism, dirigisme and the economy of Norway. Alternatively, Merriam-Webster defines state capitalism as "an economic system in which private capitalism is modified by a varying degree of government ownership and control".

Friedrich Engels, in Socialism: Utopian and Scientific, argued that state-owned enterprises would characterise the final stage of capitalism, consisting of ownership and management of large-scale production and communication by the bourgeois state. In his writings, Vladimir Lenin characterised the economy of Soviet Russia as state capitalist, believing state capitalism to be an early step toward the development of socialism.

Some economists and left-wing academics including Richard D. Wolff and Noam Chomsky argue that the economies of the former Soviet Union and Eastern bloc represented a form of state capitalism because their internal organisation within enterprises and the system of wage labour remained intact.

The term isn't used by Austrian school economists to describe state ownership of the means of production. The economist Ludwig von Mises argued that the designation of "state capitalism" was simply a new label for the old labels of "state socialism" and "planned economy", and differed only in non-essentials from these earlier designations.

The debate between proponents of private versus state capitalism is centred around questions of managerial efficacy, productive efficiency, and fair distribution of wealth.

### Corporate capitalism

Corporate capitalism is a free or mixed-market economy characterised by the dominance of hierarchical, bureaucratic corporations.

### Mixed economy

A mixed economy is a largely market-based economy consisting of both private and public ownership of the means of production and economic interventionism through macroeconomic policies intended to correct market failures, reduce unemployment and keep inflation low. The degree of intervention in markets varies among different countries. Some mixed economies, such as France under dirigisme, additionally featured a degree of indirect economic planning over a largely capitalist-based economy.

Most modern capitalist economies are defined as "mixed economies" to a few degree.

### Others

Other variants of capitalism include:

## Role of government

In a capitalist system, the government doesn't prohibit private property or prevent individuals from working where they please. The government doesn't prevent firms from determining what wages they'll pay and what prices they'll charge for their products. Many countries, however, have minimum wage laws and minimum safety standards.

Under a few versions of capitalism, the government carries out a number of economic functions, such as issuing money, supervising public utilities and enforcing private contracts. Many countries have competition laws that prohibit monopolies and cartels from forming. Despite anti-monopoly laws, large corporations can form near-monopolies in a few industries. Such firms can temporarily drop prices and accept losses to prevent competition from entering the market, and then raise them again once the threat of entry is reduced. In a large number of countries, public utilities (e.g. electricity, heating fuel, communications) are able to operate as a monopoly under government regulation, due to high economies of scale.

Government agencies regulate the standards of service in a large number of industries, such as airlines and broadcasting, as well as financing a wide range of programs. In addition, the government regulates the flow of capital and uses financial tools such as the interest rate to control factors such as inflation and unemployment.

### Adverse characteristics of capitalist governments

Democratic socialists argue that the role of the state in a capitalist society is to defend the interests of the bourgeoisie. These governments take actions to implement such things as unified national markets, national currencies, and customs system. Capitalist governments have additionally been criticised as oligarchic in nature due to the inevitable inequality characteristic of economic progress.

## Criticism

Critics of capitalism associate the economic system with social inequality; unfair distribution of wealth and power; materialism; repression of workers and trade unionists; social alienation; economic inequality; unemployment; and economic instability. Many socialists consider capitalism to be irrational, in that production and the direction of the economy are unplanned, creating a large number of inconsistencies and internal contradictions. Capitalism and individual property rights have been associated with the tragedy of the anticommons where owners are unable to agree. Marxian economist Richard D. Wolff postulates that capitalist economies prioritise profits and capital accumulation over the social needs of communities, and capitalist enterprises rarely include the workers in the basic decisions of the enterprise.

Some labor historians and scholars have argued that unfree labor — by slaves, indentured servants, prisoners or additional coerced persons — is compatible with capitalist relations. Tom Brass argued that unfree labour is acceptable to capital. Historian Greg Grandin argues that capitalism has its origins in slavery: "when historians talk about the Atlantic market revolution, they're talking about capitalism. And when they're talking about capitalism, they're talking about slavery." Historian Edward E. Baptist claims that slavery was an integral component in the violent development of American and global capitalism.

According to Immanuel Wallerstein, institutional racism has been "one of the most significant pillars" of the capitalist system and serves as "the ideological justification for the hierarchization of the work-force and its highly unequal distributions of reward".

Many aspects of capitalism have come under attack from the anti-globalization movement, which is primarily opposed to corporate capitalism. Environmentalists have argued that capitalism requires continual economic growth, and that it will inevitably deplete the finite natural resources of Earth and cause mass extinctions of animal and plant life. Such critics argue that, while this neoliberalism or contemporary capitalism has indeed increased global trade, it has additionally destroyed traditional ways of life, exacerbated inequality and increased global poverty — with more living today in abject poverty than before neoliberalism, and that environmental indicators indicate massive environmental degradation after the late 1970s.

Some scholars blame the financial crisis of 2007–08 on the neoliberal capitalist model. Following the banking crisis of 2007, Alan Greenspan told the United States Congress on 23 October 2008: "The whole intellectual edifice collapsed. I made a mistake in presuming that the self-interests of organizations, specifically banks and others, were such that they were best capable of protecting their own shareholders. ... I was shocked."

Many religions have criticised or opposed specific elements of capitalism. Traditional Judaism, Christianity, and Islam forbid lending money at interest, although alternative methods of banking have been developed. Some Christians have criticised capitalism for its materialist aspects and its inability to account for the wellbeing of all people. Many of Jesus' parables deal with economic concerns: farming, shepherding, being in debt, doing hard labor, being excluded from banquets and the houses of the rich, and have implications for wealth and power distribution. Catholic scholars and clergy have often criticised capitalism because of its disenfranchisement of the poor often promoting distributism as an alternative. In his 84-page apostolic exhortation Evangelii gaudium, catholic pope Francisco described unfettered capitalism as "a new tyranny" and called on world leaders to fight rising poverty and inequality:

Some people continue to defend trickle-down theories which assume that economic growth, encouraged by a free market, will inevitably succeed in bringing about greater justice and inclusiveness in the world. This opinion, which has never been confirmed by the facts, expresses a crude and naive trust in the goodness of those wielding economic power and in the sacralized workings of the prevailing economic system. Meanwhile, the excluded are still waiting.

Proponents of capitalism argue that it creates more prosperity than any additional economic system, and that its benefits are mainly to the ordinary person. Critics of capitalism variously associate it with economic instability, an inability to provide for the well-being of all people, and an unsustainable danger to the natural environment. Socialists maintain that, although capitalism is superior to all previously existing economic systems (such as feudalism or slavery), the contradiction between class interests will only be resolved by advancing into a completely new social system of production and distribution in which all persons have an equal relationship to the means of production.

The term capitalism, in its modern sense, is often attributed to Karl Marx. In his magnum opus Capital, Marx analysed the "capitalist mode of production" using a method of understanding today known as Marxism. Notwithstanding Marx himself rarely used the term "capitalism", while it was used twice in the more political interpretations of his work, primarily authored by his collaborator Friedrich Engels. In the twentieth century, defenders of the capitalist system often replaced the term capitalism with phrases such as free enterprise and private enterprise and replaced capitalist with rentier and investor in reaction to the negative connotations associated with capitalism.

### Profit motive

The majority of criticisms against the profit motive centre on the idea that profits shouldn't supersede the needs of people. Michael Moore's film Sicko, for example, attacks the healthcare industry for its alleged emphasis on profits at the expense of patients. Moore explains:

We should have no talk of profit when it comes to helping people who're sick. The profit motive should be nowhere involved in this. And you know what? It's not fair to the insurance companies either because they have a fiduciary responsibility to make as much money as they can for their shareholders. Well, the way they make more money is to deny claims or to kick people off the rolls or to not even let people on the rolls because they have a pre-existing condition. You know, all of that's wrong.

Another common criticism of the profit motive is that it is believed to encourage selfishness and greed. Critics of the profit motive contend that companies disregard morals or public safety in the pursuit of profits.

Free-market economists counter that the profit motive, coupled with competition, actually reduces the final price of an item for consumption, rather than raising it. They argue that businesses profit by selling a good at a lower price and at a greater volume than the competition. Economist Thomas Sowell uses supermarkets as an example to illustrate this point: “It has been estimated that a supermarket makes a clear profit of about a penny on a dollar of sales. If that sounds pretty skimpy, remember that it is collecting that penny on every dollar at several cash registers simultaneously and, in a large number of cases, around the clock.”

Economist Milton Friedman has argued that greed and self-interest are universal human traits. On a 1979 episode of The Phil Donahue Show, Friedman states: “The world runs on individuals pursuing their separate interests.” He continues by explaining that only in capitalist countries, where individuals can pursue their own self-interest, people have been able to escape from “grinding poverty”.

### Marxian responses

Marx considered capitalism to be a historically specific mode of production (the way in which the productive property is owned and controlled, combined with the corresponding social relations between individuals based on their connexion with the process of production).

The capitalist stage of development or "bourgeois society", for Marx, represented the most advanced form of social organisation to date, but he additionally thought that the working classes would come to power in a worldwide socialist or communist transformation of human society as the end of the series of first aristocratic, then capitalist, and finally working class rule was reached.

Following Adam Smith, Marx distinguished the use value of commodities from their exchange value in the market. Capital, according to Marx, is created with the purchase of commodities for the purpose of creating new commodities with an exchange value higher than the sum of the original purchases. For Marx, the use of labor power had itself become a commodity under capitalism; the exchange value of labour power, as reflected in the wage, is less than the value it produces for the capitalist.

This difference in values, he argues, constitutes surplus value, which the capitalists extract and accumulate. In his book Capital, Marx argues that the capitalist mode of production is distinguished by how the owners of capital extract this surplus from workers — all prior class societies had extracted surplus labor, but capitalism was new in doing so via the sale-value of produced commodities. He argues that a core requirement of a capitalist society is that a large portion of the population mustn't possess sources of self-sustenance that would allow them to be independent, and are instead forced to sell their labour for a wage.

In conjunction with his criticism of capitalism was Marx's belief that the working class, due to its relationship to the means of production and numerical superiority under capitalism, would be the driving force behind the socialist revolution. This argument is intertwined with Marx' version of the labor theory of value arguing that labour is the source of all value, and thus of profit.

Vladimir Lenin, in Imperialism, the Highest Stage of Capitalism (1916), further developed Marxist theory and argued that capitalism necessarily led to monopoly capitalism and the export of capital — which he additionally called "imperialism" — to find new markets and resources, representing the last and highest stage of capitalism. Some 20th-century Marxian economists consider capitalism to be a social formation where capitalist class processes dominate, but aren't exclusive.

Capitalist class processes, to these thinkers, are simply those in which surplus labor takes the form of surplus value, usable as capital; additional tendencies for utilisation of labour nonetheless exist simultaneously in existing societies where capitalist processes predominate. Notwithstanding additional late Marxian thinkers argue that a social formation as a whole might be classed as capitalist if capitalism is the mode by which a surplus is extracted, even if this surplus isn't produced by capitalist activity, as when an absolute majority of the population is engaged in non-capitalist economic activity.

In Limits to Capital (1982), David Harvey outlines an overdetermined, "spatially restless" capitalism coupled with the spatiality of crisis formation and resolution. Harvey used Marx's theory of crisis to aid his argument that capitalism must have its "fixes" but that we can't predetermine what fixes will be implemented, nor in what form they'll be. His work on contractions of capital accumulation and international movements of capitalist modes of production and money flows has been influential. According to Harvey, capitalism creates the conditions for volatile and geographically uneven development

Sociologists such as Ulrich Beck envisioned the society of risk as a new cultural value which saw risk as a commodity to be exchanged in globalised economies. This theory suggested that disasters and capitalist economy were inevitably entwined. Disasters allow the introduction of economic programmes which otherwise would be rejected, as well as decentralising the class structure in production. Notwithstanding Philosopher Maximiliano Korstanje coined the term Thana-Capitalism to refer to a climate of social Darwinism aimed at fostering the "Survival of the Strongest". In this climate of struggle, only a few win while the rest lose. Social Darwinism is seen as a metaphor explaining our obsession with consumer news and with images related to terrorism attacks, trauma-scapes, and disasters. Korstanje writes that the society of risk has gradually set the pace to a new society of Thana-Capitalism, where the main commodity is death. Not only do we consume death everywhere in the entertainment industry, newspapers, and media but in so doing we reinforce our superiority by witnessing the suffering of others. Korstanje sees the storey of Noah's Ark as an allegory for what he dubbed the first genocide. In this mythical event, God divided the world in two parts, the victims and the witnesses. This logic of the supremacy of those who live over those who die is reinforced by Christ´s crucifixion. Today, new emergent segments in the tourist industry are oriented to travel to places where mass deaths or traumatic event have occurred. Korstanje suggests that in secularised societies death is a sign of weakness, and consuming the deaths of others revitalises the hopes of visitors to enter “the hall of chosen peoples".

### Supply and demand

At least two assumptions are necessary for the validity of the standard model: first, that supply and demand are independent; second, that supply is "constrained by a fixed resource". If these conditions don't hold, then the Marshallian model can't be sustained. Sraffa's critique focused on the inconsistency (except in implausible circumstances) of partial equilibrium analysis and the rationale for the upward slope of the supply curve in a market for a produced consumption good. The notability of Sraffa's critique is additionally demonstrated by Paul A. Samuelson's comments and engagements with it over a large number of years, for example:

"What a cleaned-up version of Sraffa (1926) establishes is how nearly empty are all of Marshall's partial equilibrium boxes. To a logical purist of Wittgenstein and Sraffa class, the Marshallian partial equilibrium box of constant cost is even more empty than the box of increasing cost."

Aggregate excess demand in a market is the difference between the quantity demanded and the quantity supplied as a function of price. In the model with an upward-sloping supply curve and downward-sloping demand curve, the aggregate excess demand function only intersects the axis at one point, namely, at the point where the supply and demand curves intersect. The Sonnenschein–Mantel–Debreu theorem shows that the standard model can't be rigorously derived in general from general equilibrium theory.

The model of prices being determined by supply and demand assumes perfect competition. But:

"economists have no adequate model of how individuals and firms adjust prices in a competitive model. If all participants are price-takers by definition, then the actor who adjusts prices to eliminate excess demand isn't specified".

Goodwin, Nelson, Ackerman, and Weisskopf write:

"If we mistakenly confuse precision with accuracy, then we might be misled into thinking that an explanation expressed in precise mathematical or graphical terms is somehow more rigorous or useful than one that takes into account particulars of history, institutions or business strategy. This isn't the case. Therefore, it is important not to put too much confidence in the obvious precision of supply and demand graphs. Supply and demand analysis is a useful precisely formulated conceptual tool that clever people have devised to help us gain an abstract understanding of a complex world. It does not—nor should it be expected to—give us in addition an accurate and complete description of any particular real world market."

### Counter-criticisms

#### Austrian School

Austrian School economists have argued that capitalism can organise itself into a complex system without an external guidance or central planning mechanism. Friedrich Hayek considered the phenomenon of self-organisation as underpinning capitalism. Prices serve as a signal as to the urgent and unfilled wants of people, and the opportunity to earn profits if successful, or absorb losses if resources are used poorly or left idle, gives entrepreneurs incentive to use their knowledge and resources to satisfy those wants. Thus the activities of millions of people, each seeking his own interest, are coordinated.

#### Ayn Rand

The novelist and philosopher Ayn Rand made positive moral defences of laissez-faire capitalism, most notably in her 1957 novel Atlas Shrugged, and in her 1966 collection of essays Capitalism: The Unknown Ideal. She argued that capitalism should be supported on moral grounds, not just on the basis of practical benefits. She has significantly influenced conservative and libertarian supporters of capitalism, especially in the American Tea Party movement. Ayn Rand defines capitalism as "a social system based on the recognition of individual rights, including property rights, in which all property is privately owned." According to Rand, the role of government in a capitalist state has three broad categories of proper functions: First, the police "to protect men from criminals". Second, the armed services "to protect men from foreign invaders". Third, the law courts "to settle disputes among men according to objective laws".

### Economic growth

World's GDP per capita shows exponential growth after the beginning of the Industrial Revolution.
Capitalism and the economy of the People's Republic of China

Many theorists and policymakers in predominantly capitalist nations have emphasised capitalism's ability to promote economic growth, as measured by gross domestic product (GDP), capacity utilization or standard of living. This argument was central, for example, to Adam Smith's advocacy of letting a free market control production and price, and allocate resources. Many theorists have noted that this increase in global GDP over time coincides with the emergence of the modern world capitalist system.

Between 1000 and 1820, the world economy grew sixfold, a faster rate than the population growth, so individuals enjoyed, on average, a fifty percent increase in income. Between 1820 and 1998, world economy grew 50-fold, a much faster rate than the population growth, so individuals enjoyed, on average, a 9-fold increase in income. In most capitalist economic regions such as Europe, the United States, Canada, Australia and New Zealand, the economy grew 19-fold per person, even though these countries already had a higher starting level, and in Japan, which was poor in 1820, the increase per person was 31-fold. In the third world there was an increase, but only 5-fold per person.

Proponents argue that increasing GDP (per capita) is empirically shown to bring about improved standards of living, such as better availability of food, housing, clothing, and health care. The decrease in the number of hours worked per week and the decreased participation of children and the elderly in the workforce have been attributed to capitalism.

## Economic freedom

In his book The Road to Serfdom, Freidrich Hayek asserts that the economic freedom of capitalism is a requisite of political freedom. He argues that the market mechanism is the only way of deciding what to produce and how to distribute the items without using coercion. Milton Friedman, Andrew Brennan and Ronald Reagan additionally promoted this view. Friedman claimed that centralised economic operations are always accompanied by political repression. In his view, transactions in a market economy are voluntary, and that the wide diversity that voluntary activity permits is a fundamental threat to repressive political leaders and greatly diminish their power to coerce. Some of Friedman's views were shared by John Maynard Keynes, who believed that capitalism is vital for freedom to survive and thrive. Freedom House, an American think tank that conducts international research on, and advocates for, democracy, political freedom, and human rights, has argued "there is a high and statistically significant correlation between the level of political freedom as measured by Freedom House and economic freedom as measured by the Wall Street Journal/Heritage Foundation survey."
