19. The local zoo has hired you to assist them in setting admission prices. The zoo's managers recognize that there are two distinct demand curves for zoo admission. One demand curve applies to those ages 12 to 64, while the other is for children and senior citizens. The two demand curves are: Pa = 9.6 − 0.08Qa Pcs = 4 − 0.05Qcs where Pa = adult price, Pcs = children's/senior citizen's price, QA = daily quantity of adults, and QCS = daily quantity of children and senior citizens. Crowding is not a problem at the zoo, so that the managers consider marginal cost to be zero. If the zoo decides to price discriminate, what are the profit maximizing price and quantity in each market?
Market A: REVA = PA(QA)QA = (9.6 − 0.08QA)QA = 9.6QA − 0.08QA 2 . MRA = 9.6 − 0.16QA. Profit maximization MRA = MC , that is, 9.6 − 0.16QA = 0 and QA = 60. Consequently PA = 9.6 − 0.08 ∗ 60 = 4.8 Market CS: REVCS = PCS (QCS )QCS = (4 − 0.05QCS )QCS = 4QCS − 0.05QCS2 . MRCS = 4 − 0.1QCS . Profit maximization MRCS = MC , that is, 4 − 0.1QCS = 0 and QCS = 40. Consequently PCS = 4 − 0.05 ∗ 40 = 2
18. American Tire and Rubber Company sells identical radial tires under the firm's own brand name and private label tires to discount stores. The radial tires sold in both sub-markets are identical, and the marginal cost is constant at $10 per tire for both types. The firm has estimated the following demand curves for each of the markets. PB = 70 − 0.0005QB (brand name) PP = 20 − 0.0002QP (private label). Quantities are measured in thousands per month and price refers to the wholesale price. American currently sells brand name tires at a wholesale price of $28.50 and private label tires for a price of $17. Are these prices optimal for the firm?
No. Optimal prices should be PB = $40; PP =$15
