Market, which forms an equivalent exchange. subjective offset the cost of goods objective value – the value of value of the goods, which increases or decreases the value of the objective value of the goods when the market goes from the point of absolute equilibrium. Relative to the equilibrium market – the market where demand is balanced offer at prices that are subjective bias with respect to the objective of commodity prices. relative subjective satisfaction exchange main mass of its members – a central element of the process formation of equivalent exchange. In practice, looks like a recognition of the bulk of the participants sharing the objectivity of the prices of commodities and the profits of manufacturers. Many researchers are trying to construct a theory commodity, based on a completely objective parameters of the equivalence of exchanging goods. Moreover, not even trying this equivalence is represented as an objective basis of subjective satisfaction with the exchange its participants, as if the goods exchanged by themselves, without the subjects of exchange.
