- Chapter 5, problem #5
- Chapter 5, problem #13
- A multiproduct firm’s cost function was recently estimated as:
- Suppose the own price elasticity of market demand for beer steins is -1.5, the Rothschild index is .5, and the typical beer stein retailer enjoys sales of $70,000 annually.What is the price elasticity of demand for a representative beer stein retailer’s product?
- Chapter 7, problem #9
- A firm has 600,000 in sales, a Lerner index of .75, and a marginal cost of $25, and competes against 500 other firms in its relevant market.
- What price does the firm charge its customers?
- By what factor does this firm mark up its price over marginal cost?
- Do you think this firm enjoys much market power?Explain.
- Chapter 7, problem #15
C(Q1,Q2) = 65 – .72(Q1Q2) + 5(Q1)2 + 2(Q2)2
