Exchange value in the context of "Calculation in kind"

Capital: A Critique of Political Economy (German: Das Kapital. Kritik der politischen Ökonomie), also known as Das Kapital (German: [das kapiˈtaːl]), is a foundational theoretical text in Marxist philosophy, economics, and politics by Karl Marx. His magnum opus, the work is a critical analysis of political economy, meant to reveal the economic patterns underpinning the capitalist mode of production. Das Kapital is in three volumes, of which only the first was published in Marx's lifetime (1867); the others were completed from his notes and published by his collaborator Friedrich Engels in 1885 and 1894.

The central argument of Das Kapital is that the motivating force of capitalism is in the exploitation of labour, whose unpaid work is the ultimate source of surplus value and profit. Beginning with an analysis of the commodity, Marx argues that the capitalist mode of production is a historically specific system where social relations are mediated by commodity exchange. He posits a labour theory of value, contending that the economic value of a commodity is determined by the socially necessary labour time required for its production. Under this system, the worker's capacity to labour (their labour power) is sold as a commodity, but its use-value—the ability to create new value—is greater than its exchange-value (the wage), allowing the capitalist to extract surplus value. This process drives capital accumulation, which in turn fosters technological change, the creation of a reserve army of labour, and a long-term tendency of the rate of profit to fall, leading to economic crises and intensifying class conflict.

The labor theory of value (LTV) is a theory of value that argues that the exchange value of a good or service is determined by the total amount of "socially necessary labor" required to produce it. The contrasting system is typically known as the subjective theory of value.

The LTV is usually associated with Marxian economics, although it originally appeared in the theories of earlier classical economists such as Adam Smith and David Ricardo, and later in anarchist economics. Smith saw the price of a commodity as a reflection of how much labor it can "save" the purchaser. The LTV is central to Marxist theory, which holds that capitalists' expropriation of the surplus value produced by the working class is exploitative. Modern mainstream economics rejects the LTV and uses a theory of value based on subjective preferences.

The law of the value of commodities (German: Wertgesetz der Waren), known simply as the law of value, is a central concept in Karl Marx's critique of political economy first expounded in his polemic The Poverty of Philosophy (1847) against Pierre-Joseph Proudhon with reference to David Ricardo's economics. Most generally, it refers to a regulative principle of the economic exchange of the products of human work, namely that the relative exchange-values of those products in trade, usually expressed by money-prices, are proportional to the average amounts of human labor-time which are currently socially necessary to produce them (see Socially necessary labour time) within the capitalist mode of production.

Thus, the fluctuating exchange value of commodities (exchangeable products) is regulated by their value, where the magnitude of their value is determined by the average quantity of human labour which is currently socially necessary to produce them (see labor theory of value and value-form). Theorizing this concept and its implications preoccupied Marx for more than two decades.

Socially necessary labour time in Marx's critique of political economy is what regulates the exchange value of commodities in trade. In short, socially necessary labour time refers to the average quantity of labour time that must be performed under currently prevailing conditions to produce a commodity.

Unlike individual labour hours in the classical labour theory of value formulated by Adam Smith and David Ricardo, Marx's exchange value is conceived as a proportion (or 'aliquot part') of society's labour-time.

In Marxist philosophy, commodity fetishism is a belief that the exchange values of goods are inherent to them, rather than being expressions of the social relations in which the goods and their underlying labour are exchanged. Through commodity fetishism, social phenomena such as market value, wages and rent are reified (attributed to things, i.e. goods, labour, land) while people who determine them — traders, capitalists, landlords — are made to seem passive or obscured altogether. The concept is crucial to Karl Marx's critique of economic theory, which seeks to locate the source of profit in the capitalist economy.

Ricardian socialism is a branch of classical economic thought based upon the work of the economist David Ricardo (1772–1823). Despite Ricardo being a capitalist economist, the term is used to describe economists in the 1820s and 1830s who developed a theory of capitalist exploitation from the theory developed by Ricardo that stated that labor is the source of all wealth and exchange value. This principle extends back to the principles of English philosopher John Locke. The Ricardian socialists reasoned that labor is entitled to all it produces, and that rent, profit and interest were not natural outgrowths of the free market process but were instead distortions. They argued that private ownership of the means of production should be supplanted by cooperatives owned by associations of workers.

This designation is used in reference to economists in the early 19th century that elaborated a theory of capitalist exploitation from the classical economic proposition derived from Adam Smith and David Ricardo stating that labor is the source of wealth. Although Ricardian socialist thought had some influence on Karl Marx's theories, there is disagreement about the extent to which this is the case. Some believe Marx rejected many of the fundamental assumptions of the Ricardian socialists, including the view that labor was the source of all wealth; while others believe the Ricardian socialists, though "generally dismissed as incoherent utopians", were in fact "an important though very largely neglected" influence on Marxist economic theories.

The labor theory of value (LTV) is an economic theory that argues that the economic value of a good or service is determined by the total amount of socially necessary labor required to produce it. The LTV is usually associated with Marxian economics, although it also appears in the theories of earlier classical economists such as Adam Smith and David Ricardo.

Smith saw the price of a commodity in terms of the labor that the purchaser must expend to buy it, which embodies the concept of labor commanded. Ricardo, building on Smith, developed a more consistent labor theory of value, arguing that the value of commodities is determined by the quantity of labor embodied in their production. Karl Marx's theory, which is the most elaborate and influential, holds that value is a social relation specific to commodity-producing societies. Marx distinguished between concrete useful labor, which creates use value, and abstract labor, the substance of exchange value. He argued that the magnitude of value is determined by the average labor-time required for production under normal conditions.
