4.The demand for the book is P = 200 − 2 Q.

A bookstore can order copies that will cost $40 each.

If the bookstore orders 20 books, what is the total profit?

5.If a firm changes its product line such that costs increase but revenue increases by even more, should the firm adopt this new product line?

Yes

No

This question is borrowed from Exercise 3.5 in the book. Suppose the demand is q=D(p)=10200-100p. The cost of producing q units is q2/2 (note this implies that MC=q). Hint: Write the demand as p=102-q/100 first What is your total revenue schedule (or function)? What is your marginal revenue schedule (MR)? What is the profit-maximizing q and what is the corresponding price p? Given p and q, what is your profit?

2. Let market demand be given by Q( P) = 200 ? P. Each firm’s cost function is C(qi ) = 20qi , where i = 1, 2. (d) Does each firm have an incentive to increase output? What is the optimal defection for each firm? What does this imply about the stability of their collusive agreement? (e) Suppose that the cost function is now C(qi ) = 20qi + 400.
