productive efficiency

The correct answer is Allocative efficiency.

Explanation:

Although there are different evaluation standards for the concept of allocation efficiency, the basic principle states that, in any economic system, the different options in the allocation of resources will produce both "winners" and "losers" in relation to the choice being evaluated. The principles of rational choice theory, individual maximization, utilitarianism and market theory assume, in addition, that the results for both winners and losers can be identified, compared and measured.

From these basic premises, the objective of maximizing the efficiency in the allocation can be defined according to some neutral principle in which some options are considered “objectively better than others”. For example, an economist might say that a change in policy increases the efficiency of allocation, as long as those who benefit from the change (winners) earn more than the losers lose.
