Allocative Efficiency

Allocative efficiency is an economic state where no resources are wasted and the best possible resource allocation has been achieved.

Allocative efficiency occurs when it is impossible to make one party better off without making another party worse off. In a market, this is achieved when the price equals the marginal cost of production, ensuring that the right amount of goods are produced and consumed. Allocative efficiency is one of the conditions under which markets are considered economically efficient.

Price = Marginal Cost
Productive Efficiency

Productive efficiency is an economic state where a firm produces a given level of output at the lowest possible cost.

Productive efficiency occurs when a firm is using the least amount of inputs (resources) to produce the maximum amount of output. This is achieved when a firm is producing at the minimum point of its average total cost curve. Productive efficiency is one of the conditions under which markets are considered economically efficient.
