The 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.
Nicholas Kaldor, Baron Kaldor, born Káldor Miklós, was a Cambridge economist in the post-war period. He developed the "compensation" criteria called Kaldor–Hicks efficiency for welfare comparisons (1939), derived the cobweb model, and argued for certain regularities observable in economic growth, which are called Kaldor's growth laws. Kaldor worked alongside Gunnar Myrdal to develop the key concept Circular Cumulative Causation, a multicausal approach where the core variables and their linkages are delineated. Both Myrdal and Kaldor examine circular relationships, where the interdependencies between factors are relatively strong, and where variables interlink in the determination of major processes. Gunnar Myrdal got the concept from Knut Wicksell and developed it alongside Nicholas Kaldor when they worked together at the United Nations Economic Commission for Europe. Myrdal concentrated on the social provisioning aspect of development, while Kaldor concentrated on demand-supply relationships to the manufacturing sector. Kaldor also coined the term "convenience yield" related to commodity markets and the so-called theory of storage, which was initially developed by Holbrook Working.
Classical economics, classical political economy, or Smithian economics is a school of thought in political economy that flourished, primarily in Britain, in the late 18th and early-to-mid 19th century. Its main thinkers are held to be Adam Smith, Jean-Baptiste Say, David Ricardo, Thomas Robert Malthus, and John Stuart Mill. These economists produced a theory of market economies as largely self-regulating systems, governed by natural laws of production and exchange.
In classical economics, Say's law, or the law of markets, is the claim that the production of a product creates demand for another product by providing something of value which can be exchanged for that other product. So, production is the source of demand. In his principal work, A Treatise on Political Economy, Jean-Baptiste Say wrote: "A product is no sooner created, than it, from that instant, affords a market for other products to the full extent of its own value." And also, "As each of us can only purchase the productions of others with his own productions – as the value we can buy is equal to the value we can produce, the more men can produce, the more they will purchase."
Underconsumption 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.
Labour power is a key concept used by Karl Marx in his critique of capitalist political economy. Marx distinguished between the capacity to do work, labour power, from 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.
Wage labour, usually referred to as paid work, paid employment, or paid labour, refers to the socioeconomic relationship between a worker and an employer in which the worker sells their labour power under a formal or informal employment contract. These transactions usually occur in a labour market where wages or salaries are market-determined.
In Marxian economics, economic reproduction refers to recurrent 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.
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.
Michał Kalecki was a Polish Marxian economist. Over the course of his life, Kalecki worked at the London School of Economics, University of Cambridge, University of Oxford and Warsaw School of Economics and was an economic advisor to the governments of Poland, France, Cuba, Israel, Mexico and India. He also served as the deputy director of the United Nations Economic Department in New York City.
Prices of production is a concept in Karl Marx's critique of political economy, defined as "cost-price + average profit". A production price can be thought of as a type of supply price for products; it refers to the price levels at which newly produced goods and services would have to be sold by the producers, in order to reach a normal, average profit rate on the capital invested to produce the products.
Criticisms of the labor theory of value affect the historical concept of labor theory of value (LTV) which spans classical economics, liberal economics, Marxian economics, neo-Marxian economics, and anarchist economics. As an economic theory of value, LTV is central to Marxist social-political-economic theory and later gave birth to the concepts of labour exploitation and surplus value. LTV criticisms therefore often appear in the context of economic criticism, not only for the microeconomic theory of Marx but also for Marxism, according to which the working class is exploited under capitalism.
Throughout modern history, a variety of perspectives on capitalism have evolved based on different schools of thought.
The Theory of Capitalist Development is a 1942 book by the Marxian economist Paul Sweezy, in which the author expounds and defends the labor theory of value. It has received praise as an important work, but Sweezy has also been criticized for misrepresenting Karl Marx's economic theories.
Constant capital (c), is a concept created by Karl Marx and used in Marxian political economy. It refers to one of the forms of capital invested in production, which contrasts with variable capital (v). The distinction between constant and variable refers to an aspect of the economic role of factors of production in creating a new value.
Exploitation of labour is a concept defined as, in its broadest sense, one agent taking unfair advantage of another agent. It denotes an unjust social relationship based on an asymmetry of power or unequal exchange of value between workers and their employers. When speaking about exploitation, there is a direct affiliation with consumption in social theory and traditionally this would label exploitation as unfairly taking advantage of another person because of their inferior position, giving the exploiter the power.
In Karl Marx's critique of political economy and subsequent Marxian analyses, the capitalist mode of production refers to the systems of organizing production and distribution within capitalist societies. Private money-making in various forms 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.
In Marxian economics, surplus value is the difference between the amount raised through a sale of a product and the amount it cost to the owner of that product 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".
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.
Marxism and Keynesianism is a method of understanding and comparing the works of influential economists John Maynard Keynes and Karl Marx. Both men's works has fostered respective schools of economic thought that have had significant influence in various academic circles as well as in influencing government policy of various states. Keynes' work found popularity in developed liberal economies following the Great Depression and World War II, most notably Franklin D. Roosevelt's New Deal in the United States in which strong industrial production was backed by strong unions and government support. Marx's work, with varying degrees of faithfulness, led the way to a number of socialist states, notably the Soviet Union and the People's Republic of China. The immense influence of both Marxian and Keynesian schools has led to numerous comparisons of the work of both economists along with synthesis of both schools.
