The attributes of monopolistic competition and its similarities to perfect competition and monopoly.

Expert Solution & Answer
Check Mark

Explanation of Solution

The three main characteristics of monopolistic competition are as follows:

  1. 1. Many sellers: There are many firms competing with each other for the same customers.
  2. 2. Product differentiation: Each seller produces similar, but not identical products.
  3. 3. Free entry and exit: Firms can enter or exit the market without any restrictions.

Like in monopoly, monopolistic competitive firm faces a downward sloping demand curve as the price is greater than the marginal cost.

Also, similar to that of a perfectly competitive market, a monopolistically competitive firm drives zero economic profit in the long run. This is because, in the long run, price equals the average total cost due to free entry and exit of firms.

Economics Concept Introduction

Concept introduction:

Monopolistic competition: It is an imperfect market structure in which many firms sell products that are differentiated from one another.

Monopoly: It is the market structure characterized by a single seller who sells products that have no close substitutes.

Perfect competition: It is the perfect market structure where there are large numbers of sellers and buyers, with sellers selling homogeneous products.

Suppose the marginal social cost of television sets is $100. This is constant and equal to the average cost of television sets. The annual demand for television sets is given by the following equation: Q = 200,000-500P, where Qis the quantity sold per year and P is the price of television sets. a) If television sets are sold in a perfectly competitive market, calculate the annual number sold. Under what circumstances will the market equilibrium be efficient? b) Show the losses in well-being each year that would result from a law limiting sales of television sets to 100,000 per year. Show the effect on the price, marginal social benefit, and marginal social cost of television sets. Show the net loss in well-being that will result from a complete ban on the sales of television sets. (show with graphs.)
