When the price equals marginal cost of production, the allocation efficiency is at the output level. This is because the optimal distribution is achieved when the marginal utility of good equals the marginal cost. The price that consumer is willing to pay is same as the marginal utility of the consumer. Allocative Efficiency example
When drawing diagrams for businesses, allocative efficiency is satisfied if output is produced at the point where marginal cost is equal to average revenue. This is the case for the long-run equilibrium of perfect competition. Productive efficiency occurs when units of goods are being supplied at the lowest possible average total cost.
Perfect competition provides both allocative efficiency and productive efficiency: Such markets are allocatively efficient, as output will always occur where marginal cost is equal to average revenue i.e. price (MC = AR). In perfect competition, any profit-maximizing producer faces a market price equal to its marginal cost (P = MC).
The production function is one of the key concepts of mainstream neoclassical theories, used to define marginal product and to distinguish allocative efficiency, a key focus of economics. One important purpose of the production function is to address allocative efficiency in the use of factor inputs in production and the resulting distribution ...
Examples include importations of resources and technology, and the increase in the production of goods and services. Specifically, at all points on the frontier, the economy achieves productive efficiency : no more output of any good can be achieved from the given inputs without sacrificing output of some good.
For example, if a pollution externality leads to overproduction of tires, a tax on tires might restore the efficient level of production. A condition inefficient in the "first-best" might be desirable in the second-best. To determine whether an activity is moving the economy towards Pareto efficiency, two compensation tests have been developed.
For example, a company may have the lowest costs in "productive" terms, but the result may be inefficient in allocative terms because the "true" or social cost exceeds the price that consumers are willing to pay for an extra unit of the product. This is true, for example, if the firm produces pollution (see also external cost). Consumers would ...
For example, the standard social scoring function for first-preference plurality is the total number of voters who rank a candidate first. Every social ordering can be made into a choice function by considering only the highest-ranked outcome. Less obviously, though, every social choice function is also an ordering function.
