Explanation of Solution

The monopoly is a market structure where there is only one seller selling the unique product and the seller faces the downward sloping demand curve. The monopolist would always try to maximize the economic profit from the market. The profit maximizing level of monopolist output is obtained at the point where the marginal revenue of the monopolist equals with the marginal cost of the monopolist. When the marginal cost of producing the output is lower than the marginal revenue, the monopolist can further increase the output and increase the profit until it reaches the point where marginal revenue and cost are equal with each other.

When the marginal revenue is lower than the marginal cost of production, the revenue of the monopolist is less than the cost. Thus, the higher cost becomes an economic loss for the monopolist. Thus, at this point of economic loss, the firm should stop producing the output and it should revert back to the level where the marginal cost of production is equal to the marginal revenue. Thus, the profit of the monopolist would be maximized. The profit maximizing output can be illustrated as follows:

Microeconomics (9th Edition) (Pearson Series in Economics), Chapter 10, Problem 1RQ

Here, in the figure, the initial level of production is at the price P' and quantity Q'. Here, the marginal cost of production is higher than the marginal revenue of the monopolist, which means the production incurs loss for the monopolist. Thus, the monopolist should decrease his production to the point where the marginal revenue equals the marginal cost. This is obtained at the point where the quantity is Q* and the price is P* in order to avoid the economic loss to maximize the economic profit of the monopolist.

Price Quantity $26 0 The marketing department of $24 20,000 Johnny Rockabilly's record company $22 40,000 has determined that the demand for his $20 60,000 latest CD is given in the table at right. $18 80,000 $16 100,000 $14 120,000 The record company's costs consist of a $240,000 fixed cost of recording the CD, an $8 per CD variable cost of producing and distributing the CD, plus the cost of paying Johnny for his creative talent. 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. Johnny's payment will be be under plan 2 as…
