Math Problem Statement
- (8) a.) (4) The United States Postal Service (USPS) currently charges $0.73 per stamp. They allow stamps.com to sell a sheet of twenty stamps with personalized photos for $1.20 per stamp. Stamps.com keeps the extra beyond the $0.73 it pays the USPS. If stamps.com is acting as a profit maximizing monopolist, what is their Lerner Index and what is the price elasticity of demand for a customized stamp?
b.) (4) Suppose a movie theater determines that the elasticity of demand for movie tickets is -2.0 for senior citizens and –1.5 for adults under age 65, and the marginal cost is $5 per consumer. Use the Lerner index to determine the price senior citizens should be charged and the price adults under age 65 should be charged in order to maximize profits
