In neoclassical economics, a market distortion is any event in which a market reaches a market clearing price for an item that is substantially different from the price that a market would achieve while operating under conditions of perfect competition and state enforcement of legal contracts and the ownership of private property.
Much of the daily price fluctuation is due to random change rather than meaningful trends, creating the problem of discerning real information from noise. This problem is what drives trading in a market; if everyone knew all things, then no speculative trades would occur because it is a zero-sum game. In real life, however, trades occur as a ...
A long thread in economics (from Aristotle to classical economics to the present) distinguishes between exchange value, use value, price, and (sometimes) intrinsic value. It is frequently argued that the connection between price and other types of value is not as direct as suggested in the theory of price signals, other considerations playing a ...
Socialism is unfeasible in this view because information cannot be aggregated by a central body and effectively used to formulate a plan for an entire economy, because doing so would result in distorted or absent price signals; this is known as the economic calculation problem. [3]
Illustration of the bullwhip effect: the final customer places an order (whip), which increasingly distorts interpretations of demand as one proceeds upstream along the supply chain. The bullwhip effect is a supply chain phenomenon where orders to suppliers tend to have a larger variability than sales to buyers, which results in an amplified ...
The existence of money illusion is disputed by monetary economists who contend that people act rationally (i.e. think in real prices) with regard to their wealth. [2] Eldar Shafir , Peter A. Diamond , and Amos Tversky (1997) have provided empirical evidence for the existence of the effect and it has been shown to affect behaviour in a variety ...
In economics, a price mechanism refers to the way in which price determines the allocation of resources and influences the quantity supplied and the quantity demanded of goods and services. The price mechanism, part of a market system , functions in various ways to match up buyers and sellers: as an incentive, a signal, and a rationing system ...
Price dispersion can be viewed as a measure of trading frictions (or, tautologically, as a violation of the law of one price). It is often attributed to consumer search costs or unmeasured attributes (such as the reputation) of the retailing outlets involved. There is a difference between price dispersion and price discrimination. The latter ...
