Labour powerLabour power (Arbeitskraft; force de travail) is the capacity to do work, a key concept used by Karl Marx in his critique of capitalist political economy. Marx distinguished between the capacity to do work, labour power, and the physical act of working, labour. Labour power exists in any kind of society, but on what terms it is traded or combined with means of production to produce goods and services has historically varied greatly. Under capitalism, according to Marx, the productive powers of labour appear as the creative power of capital.
Exchange valueIn political economy and especially Marxian economics, exchange value (German: Tauschwert) refers to one of the four major attributes of a commodity, i.e., an item or service produced for, and sold on the market, the other three attributes being use value, economic value, and price. Thus, a commodity has the following: a value, represented by the socially necessary labour time to produce it (Note: the first link is to a non-Marxian definition of value); a use value (or utility); an exchange value, which is the proportion at which a commodity can be exchanged for other entities; a price (an actual selling price, or an imputed ideal price).
Value (economics)In economics, economic value is a measure of the benefit provided by a good or service to an economic agent. It is generally measured through units of currency, and the interpretation is therefore "what is the maximum amount of money a person is willing and able to pay for a good or service?” Among the competing schools of economic theory there are differing theories of value. Economic value is not the same as market price, nor is economic value the same thing as market value.
Productive and unproductive labourProductive and unproductive labour are concepts that were used in classical political economy mainly in the 18th and 19th centuries, which survive today to some extent in modern management discussions, economic sociology and Marxist or Marxian economic analysis. The concepts strongly influenced the construction of national accounts in the Soviet Union and other Soviet-type societies (see Material Product System).
Primitive communismPrimitive communism is a way of describing the gift economies of hunter-gatherers throughout history, where resources and property hunted or gathered are shared with all members of a group in accordance with individual needs. In political sociology and anthropology, it is also a concept (often credited to Karl Marx and Friedrich Engels), that describes hunter-gatherer societies as traditionally being based on egalitarian social relations and common ownership. A primary inspiration for both Marx and Engels were Lewis H.
Labor theory of valueThe labor theory of value (LTV) is a theory of value 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 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 in terms of the labor that the purchaser must expend to buy it, which embodies the concept of how much labor a commodity, a tool for example, can save the purchaser.
Productive forcesProductive forces, productive powers, or forces of production (German: Produktivkräfte) is a central idea in Marxism and historical materialism. In Karl Marx and Friedrich Engels' own critique of political economy, it refers to the combination of the means of labor (tools, machinery, land, infrastructure, and so on) with human labour power. Marx and Engels probably derived the concept from Adam Smith's reference to the "productive powers of labour" (see e.g.
Surplus labourSurplus labour (German: Mehrarbeit) is a concept used by Karl Marx in his critique of political economy. It means labour performed in excess of the labour necessary to produce the means of livelihood of the worker ("necessary labour"). The "surplus" in this context means the additional labour a worker has to do in their job, beyond earning their keep. According to Marxian economics, surplus labour is usually uncompensated (unpaid) labour.
UnderconsumptionUnderconsumption is a theory in economics that recessions and stagnation arise from an inadequate consumer demand, relative to the amount produced. In other words, there is a problem of overproduction and overinvestment during a demand crisis. The theory formed the basis for the development of Keynesian economics and the theory of aggregate demand after the 1930s. Underconsumption theory narrowly refers to heterodox economists in Britain in the 19th century, particularly from 1815 onwards, who advanced the theory of underconsumption and rejected classical economics in the form of Ricardian economics.
World-systems theoryWorld-systems theory (also known as world-systems analysis or the world-systems perspective) is a multidisciplinary approach to world history and social change which emphasizes the world-system (and not nation states) as the primary (but not exclusive) unit of social analysis. "World-system" refers to the inter-regional and transnational division of labor, which divides the world into core countries, semi-periphery countries, and the periphery countries.
