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?
The organic composition of capital (OCC) is a concept created by Karl Marx in his theory of capitalism, which was simultaneously his critique of the political economy of his time. It is derived from his more basic concepts of 'value composition of capital' and 'technical composition of capital'. Marx defines the organic composition of capital as "the value-composition of capital, in so far as it is determined by its technical composition and mirrors the changes of the latter". The 'technical composition of capital' measures the relation between the elements of constant capital and variable capital. It is 'technical' because no valuation is here involved. In contrast, the 'value composition of capital' is the ratio between the value of the elements of constant capital involved in production and the value of the labor. Marx found that the special concept of 'organic composition of capital' was sometimes useful in analysis, since it assumes that the relative values of all the elements of capital are constant.
In economics and finance, the profit rate is the relative profitability of an investment project, a capitalist enterprise or a whole capitalist economy. It is similar to the concept of rate of return on investment.
Capital accumulation is the dynamic that motivates the pursuit of profit, involving the investment of money or any financial asset with the goal of increasing the initial monetary value of said asset as a financial return whether in the form of profit, rent, interest, royalties or capital gains. The aim of capital accumulation is to create new fixed and working capitals, broaden and modernize the existing ones, grow the material basis of social-cultural activities, as well as constituting the necessary resource for reserve and insurance. The process of capital accumulation forms the basis of capitalism, and is one of the defining characteristics of a capitalist economic system.
Labour power 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, i.e. labour power, and the physical act of working, i.e. 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.
Consumption of fixed capital (CFC) is a term used in business accounts, tax assessments and national accounts for depreciation of fixed assets. CFC is used in preference to "depreciation" to emphasize that fixed capital is used up in the process of generating new output, and because unlike depreciation it is not valued at historic cost but at current market value ; CFC may also include other expenses incurred in using or installing fixed assets beyond actual depreciation charges. Normally the term applies only to producing enterprises, but sometimes it applies also to real estate assets.
In Marxism, the valorisation or valorization of capital is the increase in the value of capital assets through the application of value-forming labour in production. The German original term is "Verwertung" but this is difficult to translate. The first translation of Capital by Samuel Moore and Edward Aveling, under Engels' editorship, renders "Verwertung" in different ways depending on the context, for example as "creation of surplus-value", "self-expanding value", "increase in value" and similar expressions. These renderings were also used in the US Untermann revised edition, and the Eden and Cedar Paul translation. It has also been wrongly rendered as "realisation of capital".
The value product (VP) is an economic concept formulated by Karl Marx in his critique of political economy during the 1860s, and used in Marxian social accounting theory for capitalist economies. Its annual monetary value is approximately equal to the netted sum of six flows of income generated by production:
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.
Productive 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.
Net output is an accounting concept used in national accounts such as the United Nations System of National Accounts (UNSNA) and the NIPAs, and sometimes in corporate or government accounts. The concept was originally invented to measure the total net addition to a country's stock of wealth created by production during an accounting interval. The concept of net output is basically "gross revenue from production less the value of goods and services used up in that production". The idea is that if one deducts intermediate expenditures from the annual flow of income generated by production, one obtains a measure of the net new value in the new products created.
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.
Okishio's theorem is a theorem formulated by Japanese economist Nobuo Okishio. It has had a major impact on debates about Marx's theory of value. Intuitively, it can be understood as saying that if one capitalist raises his profits by introducing a new technique that cuts his costs, the collective or general rate of profit in society goes up for all capitalists. In 1961, Okishio established this theorem under the assumption that the real wage remains constant. Thus, the theorem isolates the effect of pure innovation from any consequent changes in the wage.
Capital. A Critique of Political Economy. Volume I: The Process of Production of Capital is the first of three treatises that make up Das Kapital, a critique of political economy by the German philosopher and economist Karl Marx. First published on 14 September 1867, Volume I was the product of a decade of research and redrafting and is the only part of Das Kapital to be completed during Marx's life. It focuses on the aspect of capitalism that Marx refers to as the capitalist mode of production or how capitalism organises society to produce goods and services.
In classical political economy and especially Karl Marx's critique of political economy, a commodity is any good or service produced by human labour and offered as a product for general sale on the market. Some other priced goods are also treated as commodities, e.g. human labor-power, works of art and natural resources, even though they may not be produced specifically for the market, or be non-reproducible goods. This problem was extensively debated by Adam Smith, David Ricardo, and Karl Rodbertus-Jagetzow, among others. Value and price are not equivalent terms in economics, and theorising the specific relationship of value to market price has been a challenge for both liberal and Marxist economists.
In economics, the marginal product of labor (MPL) is the change in output that results from employing an added unit of labor. It is a feature of the production function and depends on the amounts of physical capital and labor already in use.
Exploitation is a concept defined as, in its broadest sense, one agent taking unfair advantage of another agent. When applying this to labour 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 vulnerable position, giving the exploiter the power.
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.
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".
