Pluralism in economicsThe pluralism in economics movement is a campaign to change the teaching and research in economics towards more openness in its approaches, topics and standpoints it considers. The goal of the movement is to "reinvigorate the discipline ... [and bring] economics back into the service of society". Some have argued that economics had greater scientific pluralism in the past compared to the monist approach that is prevalent today.
Reproduction (economics)In Marxian economics, economic reproduction refers to recurrent (or cyclical) processes. Michel Aglietta views economic reproduction as the process whereby the initial conditions necessary for economic activity to occur are constantly re-created. Marx viewed reproduction as the process by which society re-created itself, both materially and socially.
Capital (economics)In economics, capital goods or capital are "those durable produced goods that are in turn used as productive inputs for further production" of goods and services. At the macroeconomic level, "the nation's capital stock includes buildings, equipment, software, and inventories during a given year." A typical example is the machinery used in factories. Capital can be increased by the use of the factors of production, which however excludes certain durable goods like homes and personal automobiles that are not used in the production of saleable goods and services.
Primitive accumulation of capitalIn Marxian economics and preceding theories, the problem of primitive accumulation (also called previous accumulation, prior accumulation, or original accumulation) of capital concerns the origin of capital and therefore how class distinctions between possessors and non-possessors came to be. Adam Smith's account of primitive-original accumulation depicted a peaceful process in which some workers laboured more diligently than others and gradually built up wealth, eventually leaving the less diligent workers to accept living wages for their labour.
Surplus productSurplus product (Mehrprodukt) is a concept theorised by Karl Marx in his critique of political economy. Roughly speaking, it is the extra goods produced above the amount needed for a community of workers to survive at its current standard of living. Marx first began to work out his idea of surplus product in his 1844 notes on James Mill's Elements of political economy. Notions of "surplus produce" have been used in economic thought and commerce for a long time (notably by the Physiocrats), but in Das Kapital, Theories of Surplus Value and the Grundrisse Marx gave the concept a central place in his interpretation of economic history.
Law of valueThe 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 within the capitalist mode of production.
Value-formThe value-form or form of value (Wertform) is a concept in Karl Marx's critique of political economy. Marx's account of the value-form is differently adopted in later forms of Marxism, in the Frankfurt School and in post-Marxism. When social labor is split up into independent enterprises and organized capitalistically, its products take the form of an ensemble of commodities of diverse types, which face one another on the market.
Unequal exchangeUnequal exchange is used primarily in Marxist economics, but also in ecological economics (more specifically also as ecologically unequal exchange), to denote forms of exploitation hidden in or underwriting trade. Unequal exchange is usually calculated by assuming that any trade between a country with a high price level and a country with a low price level, is exploitation.
Reserve army of labourReserve army of labour is a concept in Karl Marx's critique of political economy. It refers to the unemployed and underemployed in capitalist society. 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 also 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 command or authority of the owners of capital.
Tendency of the rate of profit to fallThe tendency of the rate of profit to fall (TRPF) is a theory in the crisis theory of political economy, according to which the rate of profit—the ratio of the profit to the amount of invested capital—decreases over time. This hypothesis gained additional prominence from its discussion by Karl Marx in Chapter 13 of Capital, Volume III, but economists as diverse as Adam Smith, John Stuart Mill, David Ricardo and Stanley Jevons referred explicitly to the TRPF as an empirical phenomenon that demanded further theoretical explanation, although they differed on the reasons why the TRPF should necessarily occur.
