주관적 가치 이론

Subjective theory of value

주관적 가치 이론은 재화의 가치는 어떤 본질적인 재산에 의해서도 결정되지 않고, 그것을 생산하는 데 필요한 노동의 양에 의해서 결정되는 것이 아니라, 행위하는 개인이 자신의 소기의 목적을 달성하기 위해 재화에 두는 중요성에 의해서 결정된다는 생각을 진전시키는 경제 이론이다.[1]

이 이론의 현대판은 19세기 후반 윌리엄 스탠리 제본스, 레온 왈라스, 칼 멩거에 의해 독립적으로 거의 동시에 만들어졌다.[2]

Overview

According to the subjective theory of value, by assuming that all trades between individuals are voluntary, it can be concluded that both parties to the trade subjectively perceive the goods, labour or money they receive, as being of higher value to the goods, labour or money they give away. The theory holds that one can create value simply by trading with someone who values the items higher, without necessarily modifying those. Wealth is understood to refer to individuals' subjective valuation of their possessions, and voluntary trades may increase the total wealth in society.[3]

Individuals will tend to obtain diminishing levels of satisfaction, or marginal utility from acquiring additional units of a good. They will initially prioritise obtaining the goods they most need (of central, not marginal utility), such as essential food, but once their need for it is satisfied up to a certain level, their desire for other goods will start to assume more relative importance, and they will seek to bring satisfaction of their need for feeding into satisfaction of their need for other goods.[4]

Proponents of the theory also believe that in a free market, competition between individuals seeking to trade goods they possess and services they can provide for goods they perceive as being of higher value to them results in a market equilibrium set of prices emerging.

Classical economists such as David Ricardo believed that individual people obtain different levels of utility or 'value in use' from a service, but did not effectively connect those with market prices, or 'value in exchange', seeing them as separately derived from the quantity of labour input and other production factors.[2]

Carl Menger argued that production was simply another case of the theory of marginal utility,[2] and that labourers' wage-earning potential is set by the value of their work to others rather than subsistence costs, and they work because they value remuneration more highly than inactivity.[5]

It has to be noted that the amount of labour needed to manufacture goods can indirectly affect their prices, since it can make them more or less scarce.

Diamond-water paradox

The development of the subjective theory of value was partly motivated by the need to solve the value-paradox which had puzzled many[who?] classical economists. This paradox, also referred to descriptively as the diamond-water paradox, arose when value was attributed to things such as the amount of labor that went into the production of a good or alternatively to an objective measure of the usefulness of a good. The theory that it was the amount of labor that went into producing a good that determined its value proved equally futile because someone could stumble upon the discovery of a diamond while out for a hike, for example, which would require minimal labor, but yet the diamond could still be valued higher than water.[citation needed]

The subjective theory of value presents what it sees as a solution to this paradox by arguing that value is not determined by individuals choosing among entire abstract classes of goods, such as all the water in the world versus all the diamonds in the world. Rather, an acting individual is faced with the choice between definite quantities of goods, and the choice made by such an actor is determined by which good of a specified quantity will satisfy the individual's highest subjectively ranked preference, or most desired end.[6] Water is very abundant, therefore its marginal utility is not that high, despite its important function in keeping organisms alive.
