How do you find allocatively efficient quantity?

How do you find allocatively efficient quantity?

When a purely competitive industry is in a long-run equilibrium, quantity supplied equals quantity demanded (this is the profit maximizing quantity) AND therefore marginal social cost equals marginal social benefit (MSC = MSB), this is the allocatively efficient quantity.

Is monopoly allocatively efficient?

Monopolists are not allocatively efficient, because they do not produce at the quantity where P = MC. As a result, monopolists produce less, at a higher average cost, and charge a higher price than would a combination of firms in a perfectly competitive industry.

How do you find allocative efficiency in monopoly?

Allocative efficiency: occurs where P = MC. Economies of scale (natural monopoly) may make monopoly the most efficient market model in some industries.

Are monopolies allocatively efficient in the short run?

A monopolistically competitive industry does not display productive and allocative efficiency in either the short run, when firms are making economic profits and losses, nor in the long run, when firms are earning zero profits.

Why are monopolies inefficient?

Oligopolies are inefficient for the same reasons that monopolies are—in order to reap economic profits, they produce too little output so they create deadweight losses to society. The more like a monopoly a given oligopoly is, the higher their profits and the greater the deadweight loss.

What is allocative efficiency?

Allocative efficiency. Allocative efficiency is a state of the economy in which production represents consumer preferences; in particular, every good or service is produced up to the point where the last unit provides a marginal benefit to consumers equal to the marginal cost of producing.

What is efficient allocation?

An efficient allocation of resources is: That combination of inputs, outputs and distribution of inputs, outputs such that any change in the economy can make someone better off (as measured by indifference curve map) only by making someone worse off ( pareto efficiency).
