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.
In 20th-century discussions of Karl Marx's economics, the transformation problem is the problem of finding a general rule by which to transform the "values" of commodities into the "competitive prices" of the marketplace. This problem was first introduced by Marxist economist Conrad Schmidt and later dealt with by Marx in chapter 9 of the draft of volume 3 of Capital. The essential difficulty was this: given that Marx derived profit, in the form of surplus value, from direct labour inputs, and that the ratio of direct labour input to capital input varied widely between commodities, how could he reconcile this with a tendency toward an average rate of profit on all capital invested among industries, if such a tendency exists?
Paul Marlor Sweezy was a Marxist economist, political activist, publisher, and founding editor of the long-running magazine Monthly Review. He is best remembered for his contributions to economic theory as one of the leading Marxian economists of the second half of the 20th century.
Simple commodity production, is a term coined by Friedrich Engels in 1894 when he had compiled and edited the third volume of Marx's Capital. It refers to productive activities under the conditions of what Karl Marx had called the "simple exchange" or "simple circulation" of commodities, where independent producers trade their own products to obtain other products in exchange. The use of the adjective simple is not intended to refer to the nature of the producers or of their production, but rather to the relatively simple and straightforward exchange processes involved, from an economic perspective.
Superprofit, surplus profit or extra surplus-value is a concept in Karl Marx's critique of political economy subsequently elaborated by Vladimir Lenin and other Marxist thinkers.
Surplus labour 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. The "surplus" in this context means the additional labour a worker has to do in their job, beyond earning their own keep. According to Marxian economics, surplus labour is usually uncompensated (unpaid) labour. Marx's first analysis of what surplus labour means appeared in The Poverty of Philosophy (1847), a polemic against the philosophy of Pierre-Joseph Proudhon. A much more detailed analysis is presented in the volumes of Theories of Surplus Value and Das Kapital.
The law of the value of commodities, 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.
The 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 William 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.
Criticism of Marxism has come from various political ideologies, campaigns and academic disciplines. This includes general intellectual criticism about dogmatism, a lack of internal consistency, criticism related to materialism, arguments that Marxism is a type of historical determinism or that it necessitates a suppression of individual rights, issues with the implementation of communism and economic issues such as the distortion or absence of price signals and reduced incentives. In addition, empirical and epistemological problems are frequently identified.
Differential ground rent and absolute ground rent are concepts used by Karl Marx in the third volume of Das Kapital to explain how the capitalist mode of production would operate in agricultural production, under the condition where most agricultural land was owned by a social class of land-owners who could obtain rent income from farm production. Rent as an economic category is regarded by Marx as one form of surplus value just like net interest income, net production taxes and industrial profits. Marx's main texts on rent theory can be found in the second (edited) volume of Theories of Surplus Value and in Part 6 of Capital, Volume III. Anwar M. Shaikh states that "These remarkably rich and insightful sections of his work are seldom mentioned in the Marxian literature, and are even less understood."
Monopoly Capital: An Essay on the American Economic and Social Order is a 1966 book by the Marxian economists Paul Sweezy and Paul A. Baran. It was published by Monthly Review Press. It made a major contribution to Marxian theory by shifting attention from the assumption of a competitive economy to the monopolistic economy associated with the giant corporations that dominate the modern accumulation process. Their work played a leading role in the intellectual development of the New Left in the 1960s and 1970s. As a review in the American Economic Review stated, it represented "the first serious attempt to extend Marx’s model of competitive capitalism to the new conditions of monopoly capitalism." It attracted renewed attention following the Great Recession.
Throughout modern history, a variety of perspectives on capitalism have evolved based on different schools of thought.
Karl Marx and the Close of His System is an 1896 book critical of the economic writings of Karl Marx by the Austrian economist Eugen von Böhm-Bawerk. In the critique, he claims to expose some of the many flaws of the writings of Karl Marx. The text offered an early analysis of Marxist theory.
Marx after Sraffa is a 1977 book about Marxist economics by the economist Ian Steedman, in which the author argues against the labor theory of value.
An Essay on Marxian Economics is an analytical essay written by in 1942 by economist Joan Robinson. The essay deals with the orthodox teachings of capital accumulation, the essential demand crisis and real wages by comparing it to Karl Marx's Das Kapital. It is a wide-ranging critique on Marx and Orthodox economics while also arguing for a long-term economic view that builds on the problems that Marx first identified in the exploitative nature of capitalism.
In Marxian economics, surplus value is the difference between the amount raised through a sale of a product and the amount it cost to manufacture it: i.e. the amount raised through sale of the product minus the cost of the materials, plant and labour power. The concept originated in Ricardian socialism, with the term "surplus value" itself being coined by William Thompson in 1824; however, it was not consistently distinguished from the related concepts of surplus labor and surplus product. The concept was subsequently developed and popularized by Karl Marx. Marx's formulation is the standard sense and the primary basis for further developments, though how much of Marx's concept is original and distinct from the Ricardian concept is disputed. Marx's term is the German word "Mehrwert", which simply means value added, and is cognate to English "more worth".
The socialist mode of production, also known as socialism or communism, is a specific historical phase of economic development and its corresponding set of social relations that emerge from capitalism in the schema of historical materialism within Marxist theory. The Marxist definition of socialism is that of production for use-value, therefore the law of value no longer directs economic activity. Marxist production for use is coordinated through conscious economic planning. According to Marx, distribution of products is based on the principle of "to each according to his needs"; Soviet models often distributed products based on the principle of "to each according to his contribution". The social relations of socialism are characterized by the proletariat effectively controlling the means of production, either through cooperative enterprises or by public ownership or private artisanal tools and self-management. Surplus value goes to the working class and hence society as a whole.
Capital: A Critique of Political Economy, also known as Capital and Das Kapital, is a foundational theoretical text in materialist philosophy and critique of political economy written by Karl Marx, published as three volumes in 1867, 1885, and 1894. The culmination of his life's work, the text contains Marx's analysis of capitalism, to which he sought to apply his theory of historical materialism "to lay bare the economic law of motion of modern society", following from classical political economists such as Adam Smith and David Ricardo. The text's second and third volumes were completed from Marx's notes after his death and published by his colleague Friedrich Engels. Das Kapital is the most cited book in the social sciences published before 1950.
Marxian economics, or the Marxian school of economics, is a heterodox school of political economic thought. Its foundations can be traced back to Karl Marx's critique of political economy. However, unlike critics of political economy, Marxian economists tend to accept the concept of the economy prima facie. Marxian economics comprises several different theories and includes multiple schools of thought, which are sometimes opposed to each other; in many cases Marxian analysis is used to complement, or to supplement, other economic approaches. Because one does not necessarily have to be politically Marxist to be economically Marxian, the two adjectives coexist in usage, rather than being synonymous: They share a semantic field, while also allowing both connotative and denotative differences. An example of this can be found in the works of Soviet economists like Lev Gatovsky, who sought to apply Marxist economic theory to the objectives, needs, and political conditions of the socialist construction in the Soviet Union, contributing to the development of Soviet Political Economy.
Crisis theory, concerning the causes and consequences of the tendency for the rate of profit to fall in a capitalist system, is associated with Marxian critique of political economy, and was further popularised through Marxist economics.
