Chapter 15, Problem 13P
To determine
Concept Introduction:
- Large number of buyers and sellers: In monopolistic competition market, there are a large number of sellers and buyers.
- Product differentiation: This is one of the most important features of monopolistic competition. The product of the sellers is differentiated but are close substitutes of one another. It can be real or artificial. The
demand curve monopolistic firms face is anelastic demand curve.
- Free Entry or Exit: There are no barriers to entry or exit, firms can easily enter or exit the market.
- In case of monopolistic market competition, short run equilibrium is achieved at a point where the marginal revenue is equal to the marginal cost.
- In such markets, the marginal revenue is less elastic than the average revenue curve and both are downward sloping.
- The difference between the average revenue curve that is, the demand curve and the average cost curve gives the net profit
- In the long run, the equilibrium is achieved in a place where the average revenue is equal to the marginal revenue. But the normal profit is zero.
- Since, the point does not have a minimum average cost, hence the monopolistic structure does not show product efficiency as well as
allocative efficiency.

The company is considering two plans for paying Johnny. Plan 1: Johnny receives a zero fixed recording fee and a $4 per CD royalty for each CD that is sold. Plan 2: Johnny receives a $400,000 fixed recording fee and zero royalty per CD sold. Under either plan, the record company will choose the price of Johnny's CD so as to maximize its (the record company's) profit. The record company's profit is the revenues minus costs, where the costs include the costs of production, distribution, and the payment made to Johnny.
