3. When Apple introduced its first portable media player, the iPod, its constant marginal cost of producing the top-of-the-line model was $200 (iSuppli), its fixed cost was approximately $736 million, and we estimate that its inverse demand function was p = 600 - 25Q, where Q is units measured in millions. Be sure to express your answers in the proper units, where needed.

a. What was Apple's average cost function?

b. Assuming that Apple was maximizing its short-run monopoly profit, what was its marginal revenue function?

c. What were its profit-maximizing price, quantity, profit and Lerner Index?

d. What was the price elasticity of demand at the profit maximizing level?

When Apple introduced the iPod in 2001, the iPhone in 2007 and the iPad in 2010, it substantially innovated respectively the multimedia player, the smartphone and the tablet industry. Consider the demand for an innovative Apple product y as D(p) = 1000 – p, and a cost function of c(y)=200∙y. At first consider Apple having a monopoly in this market. What is the inverse demand curve p(y)? With profits being π = p(y)∙y – c(y), what is the profit maximizing...

2. When Apple introduced its first iPhone, it had few competitors and so it set a price of $500 when its unit cost was $350. The economics consulting firm it hired to estimate the demand elasticity confirmed this was the optimal price. Since then, entry into the mobile market has occurred that make customers more price conscious. When it brought the economics consulting firm back to estimate the demand price elasticity, it found that demand had become more price elastic...

A monopolist with a constant marginal cost of production of 10 maximizes its profit by choosing to produce where the price elasticity of demand is –3. (Recall that MR = p(1 + 1/ε) where MR is marginal revenue, p is price and ε is the point price elasticity of demand.) A. If price is decreased (from its profit maximizing level) by a small amount, revenue of the monopolist will increase. B. If the monopolist’s fixed cost increases, its profit maximizing...

A producer of athletic shoes produces all of its basketball shoes at a constant marginal cost of $50 per pair. It sells a brand-name version of the shoe with a basketball star endorsement to one market (A) and an identical “discount” brand version to another separate market (B). The demand for the shoes in each market is given by: QA = 100 – 0.2p QB = 40 – 0.4p What is the price per pair in the brand-name market (A)...

An industry produces its product, Scruffs, at a constant marginal cost of $50. The market demand for Scruffs is equal to Q=75,000−500PQ What is the value to a monopolist who is able to develop a patented process for producing Scruffs at a cost of only $45? $_____________ If the industry producing Scruffs is purely competitive, what is the maximum benefit that an inventor of a process that will reduce the cost of producing Scruffs by $5 per unit can expect...

3. Suppose that Perfect Labs produces autoclaves (laboratory equipment) at a constant marginal cost equal to $20,000 and a fixed cost of $10 billion. Perfect Labs sells its autoclaves in Canada and in Germany. You are trying to determine the best pricing strategy for Perfect Labs and you know that the demands in each country are the following: QG =4,000,000 - 100PG and QC =1,000,000 - 20PC where subscript G denotes Germany and subscript C denotes Canada. (a) What is...

Suppose a monopoly with constant marginal cost of 10 sells its product to identical consumers. Each consumer has an inverse demand curve given by P = 210 − 10Q. (a) Find the price and quantity the monopolist chooses if it can only set one price, and it can not use a two-part tariff. What is the monopolist’s profit on each consumer? (b) Now suppose the monopolist can use a two-part tariff. What is the profit maximizing choice of the fixed...
