Theory of value (economics) in the context of "Agent (economics)"

In economics, economic value is a measure of the benefit provided by a good or service to an economic agent, and value for money represents an assessment of whether financial or other resources are being used effectively in order to secure such benefit. Economic value 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?” Value for money is often expressed in comparative terms, such as "better", or "best value for money", but may also be expressed in absolute terms, such as where a deal does, or does not, offer value for money.

Among the competing schools of economic theory there are differing theories of value.

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.

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 as a reflection of how much labor it can "save" the purchaser. The LTV is central to Marxist theory, which holds that capitalists' expropriation of the surplus value produced by the working class is exploitative. Modern mainstream economics rejects the LTV and uses a theory of value based on subjective preferences.

The subjective theory of value (STV) is an economic theory for explaining how the value of goods and services are not only established but also how they can fluctuate over time. The contrasting system is typically known as the labor theory of value.

STV's development helped to better understand human action and decision making in economics. The theory claims that the value of a good is not determined by any inherent property of the good, nor by the cumulative value of components or labor needed to produce it, but instead is determined by the individuals or entities who are buying (and/or selling) that good.

In sociology and in economics, the term sign value denotes and describes the value accorded to an object because of the prestige (social status) that it imparts upon the possessor, rather than the material value and utility derived from the function and the primary use of the object. For example, the buyer of a Rolls-Royce limousine might partly value the automobile as transport, yet might also value it as a sign that signifies his or her wealth to a particular community and to society in general. The automobile's transport-function is primary, from which arises its use-value, whilst the social prestige function is secondary, from which arises its sign-value.

The French sociologist Jean Baudrillard proposed the theory of sign value as a philosophic and economic counterpart to the dichotomy of exchange-value vs. use-value, which Karl Marx recognized as a characteristic of capitalism as an economic system.

Friedrich von Wieser (German: [fɔn ˈviːzɐ]; 10 July 1851 – 22 July 1926) was an early (so-called "first generation") economist of the Austrian School of economics. Born in Vienna, the son of Privy Councillor Leopold von Wieser, a high official in the war ministry, he first trained in sociology and law. In 1872, the year he took his degree, he encountered Austrian-school founder Carl Menger's Grundsätze and switched his interest to economic theory. Wieser held posts at the universities of Vienna and Prague until succeeding Menger in Vienna in 1903, where along with his brother-in-law Eugen von Böhm-Bawerk he shaped the next generation of Austrian economists including Ludwig von Mises, Friedrich Hayek and Joseph Schumpeter in the late 1890s and early 20th century. He was the Austrian Minister of Commerce from August 30, 1917, to November 11, 1918.

Wieser is renowned for two main works, Natural Value, which carefully details the alternative-cost doctrine and the theory of imputation; and his Social Economics (1914), an ambitious attempt to apply it to the real world. His explanation of marginal utility theory was decisive, at least terminologically. It was his term Grenznutzen (building on von Thünen's Grenzkosten) that developed into the standard term "marginal utility", not William Stanley Jevons's "final degree of utility" or Menger's "value". His use of the modifier "natural" indicates that he regarded value as a "natural category" that would pertain to any society, no matter what institutions of property had been established.
