Smyth Industries operated as a monopolist for the past several years, earning annual profits amounting to $50 million, which it could have maintained if Jones Incorporated did not enter the market. The result of this increased competition is lower prices and lower profits; Smyth Industries now earns $10 million annually. The managers of Smyth Industries are trying to devise a plan to drive Jones Incorporated out of the market so Smyth can regain its monopoly position (and profit). One of Smyth's managers suggests pricing its product 50 percent below marginal cost for exactly one year. The estimated impact of such a move is a loss of $1 billion. Ignoring antitrust concerns, compute the present value of Smyth Industries' profits if it could have remained a monopoly when the interest rate was 5 percent.

As a manager of a chain of movie theaters that are monopolies in their respective markets, you have noticed much higher demand on weekends than during the week. You therefore conducted a study that has revealed two different demand curves at your movie theaters. On weekends, the inverse demand function is P = 20 - 0.001Q; on weekdays, it is P = 15 - 0.002Q. You acquire legal rights from movie producers to show their films at a cost of $25,000 per movie, plus a $2.50 "royalty" for each moviegoer entering your theaters (the average moviegoer in your market watches a movie only once). What price should you charge on weekends? What price should you charge on weekdays?
The manager of a convenience store competes in a monopolistically competitive market and buys cola from a supplier at a price of $1.25 per liter. The manager thinks that because there are several supermarkets nearby, the demand for cola sold at her store is slightly more elastic than the elasticity for the representative food store reported in Table (which is −3.8). Based on this information, she perceives that the elasticity of demand for cola sold by her store is −4. What price should the manager charge for a liter of cola to maximize profits?

- In perfectly competitive markets, there are so many firms that no one firm can influence price. If any of them try to raise their prices above their competitors’ prices, their customers simply switch and buy their competitors’ products. Monopolies are at the other end of the market spectrum. In a pure monopoly, there is only one firm that services the entire market. A pure monopolist can influence price by varying its level of output until it reaches the level of output that results in the highest level of profit for the firm. Please answer the following questions: What advantages do monopolies have for the economy? What disadvantages do monopolies have for the economy?arrow_forwardIn 1896, Colgate dental cream was introduced in tubes similar to those we use now. Today, the Colgate-Palmolive Company’s brand of toothpaste is the best-selling toothpaste in the world (ahead of the Crest brand marketed by Procter & Gamble, which was introduced in 1955). While Colgate and Crest enjoy the lion’s share of the toothpaste market, if you view the oral care shelf at your local drugstore or supermarket, you will find over a hundred different varieties of toothpaste. Colgate alone sells over 40 different varieties that are marketed under names ranging from Shrek Bubble Fruit to Colgate Total Advanced Whitening. The high level of product differentiation in the toothpaste market stems from firms introducing new varieties in an attempt to boost their economic profits. In environments where makers of other brands (such as Crest) can easily enter profitable segments of the market, a profitable strategy is to attempt to quickly cover that segment (introducing Shrek Bubble Fruit…arrow_forwardIn 1896, Colgate dental cream was introduced in tubes similar to those we use now.

- Airlines primarily use ___ price discrimination.arrow_forwardYou own a franchise of rental car agencies in Florida. You recently read a report indicating that about 80 percent of all tourists visit Florida during the winter months in any given year and that 60 percent of all tourists traveling to Florida by air rent automobiles. Travelers not planning ahead often have great difficulty finding rental cars due to high demand. However, during nonwinter months tourism drops dramatically and travelers have no problem securing rental car reservations. Determine the optimal pricing strategy, and explain why it is the best pricing strategy.arrow_forwardAn international airline in Ghana ,Emirates ,estimates that the price elasticity of demand for business who travellers weekdays is -3,while that for vacation travellers who travel on weekends is -5 .if the aim of the airline is to maximise profit what pricing strategy will you recommend to the airline and why?arrow_forward
- In a statement to Gillette’s shareholders, its CEO indicated, “Despite several new product launches, Gillette’s advertising-to-sales declined dramatically . . . to 7.5 percent last year. Gillette’s advertising spending, in fact, is one of the lowest in our peer group of consumer product companies.” If the elasticity of demand for Gillette’s consumer products is similar to that of other firms in its peer group (which averages –4), what is Gillette’s advertising elasticity? Is Gillette’s demand more or less responsive to advertising than other firms in its peer group?

It is currently the only firm in the market, and it earns $10 million per year by charging the monopoly price of $115 per chip. Baker is concerned that a new firm might soon attempt to clone its product. If successful, this would reduce Baker’s profit to $4 million per year. Estimates indicate that, if Baker increases its output to 280,000 units (which would lower its price to $100 per chip), the entrant will stay out of the market and Baker will earn profits of $8 million per year for the indefinite future. 1. What must Baker do to credibly deter entry by limit pricing? 2. Does it make sense for Baker to limit price if the interest rate is 10 percent?arrow_forward
