Which term describes the optimal allocation of resources to maximize returns?

Allocative efficiency refers to a state in which resources are distributed in a way that maximizes the total benefit received by society. This occurs when the price of a good reflects its marginal cost, meaning that the last unit of a good produced provides a benefit to consumers equal to the cost of resources used to produce it. In this situation, resources are allocated to their most valued uses, ensuring that goods and services produced meet consumer preferences optimally.

When an economy achieves allocative efficiency, it indicates that resources are being used in the most efficient way possible to satisfy consumer demand, and no reallocation can increase overall satisfaction without making someone worse off. This concept is crucial in understanding how economies function and the importance of resource management to enhance overall economic welfare.

In contrast to allocative efficiency, productive efficiency pertains to producing goods at the lowest possible cost, and market equilibrium addresses the point where supply meets demand, which doesn't necessarily guarantee resources are allocated in accordance with societal preferences. Diminishing returns, on the other hand, describes a situation in production where adding more of one factor, keeping others constant, will eventually yield lower per-unit returns, not addressing optimal resource allocation directly.
