Allocative efficiency

Allocative efficiency is a state of the economy in which production is aligned with consumer preferences; in particular, the set of outputs is chosen so as to maximize the wellbeing of society. This is achieved if every good or service is produced up until the last unit provides a marginal benefit to consumers equal to the marginal cost of production. In economics, allocative efficiency entails production at the point on the production possibilities frontier that is optimal for society. In contract theory, allocative efficiency is achieved in a contract in which the skill demanded by the offering party and the skill of the agreeing party are the same. Resource allocation efficiency includes two aspects: At the macro aspect, it is the allocation efficiency of social resources, which is achieved through the economic system arrangements of the entire society. The micro aspect is the use efficiency of resources, which can be understood as the production efficiency of the organization, which can be improved through innovation and progress within the organizations. Although there are different standards of evaluation for the concept of allocative efficiency, the basic principle asserts that in any economic system, choices in resource allocation produce both "winners" and "losers" relative to the choice being evaluated. The principles of rational choice, individual maximization, utilitarianism and market theory further suppose that the outcomes for winners and losers can be identified, compared, and measured. Under these basic premises, the goal of attaining allocative efficiency can be defined according to some principles where some allocations are subjectively better than others. For example, an economist might say that a policy change is an allocative improvement as long as those who benefit from the change (winners) gain more than the losers lose (see Kaldor–Hicks efficiency). An allocatively efficient economy produces an "optimal mix" of commodities. A firm is allocatively efficient when its price is equal to its marginal costs (that is, P = MC) in a perfect market.
