The price elasticity of demand for a textbook sold in the United States is estimated to be -2, whereas the price elasticity of demand for books sold overseas is -3. The U.S. market requires hardcover books with a marginal cost of $40; the overseas market is normally served with softcover texts on newsprint, having a marginal cost of only $15.   The profit-maximizing price in the U.S. market is               and the profit-maximizing price in the overseas market is              .   MR=Px(1+1/Ed)

An end-of-aisle price promotion changes the price elasticity of a good from −3 to −4. Suppose the normal price is $18, which equates marginal revenue with marginal cost at the initial elasticity of –3. What should the promotional price be when the elasticity changes to –4? (Hint: In other words, what price will equate marginal revenue and marginal cost?)

The long-run own-price elasticity for corn at the farm level is –0.372. Because of a late freeze in Iowa, corn production is expected fall by 16 percent. Regional corn prices are likely to:

Using data on automobile purchases, P. McCarty (REStat 1996) estimated the following elasticities for compact cars sold in the United States. Own elasticity of demand Income Elasticity Cross Price* - 0.87 1.70 .82 * Responsiveness of demand for compact cars to changes in the price of other types of car models, such as luxury cars. а) What is the percent change in quantity demanded for compact cars given a 2 percent decrease in the price of compact cars? b) What is the percent change in demand for compact cars given a 2 percent decrease in the price of other car models? c) What is the percent change in demand for compact cars given a 2 percent decrease in income? d) Is demand for compact cars elastic or inelastic? Explain briefly. e) Would a decrease in the price of compact cars generate more or less revenue from the sale of compact cars? f) Are compact cars a normal or inferior good? Explain briefly. 5.
