Question 1:
-
Suppose that the monopolist faces a linear demand curve, P(Q) = A - BQ. Further suppose
that the monopolist has the marginal cost function: MC = Q.
1. Find the revenue as a function of Q.
2. Find the marginal revenue as a function of Q.
3. Find the quantity that maximizes the monopolist's profit as a function of A and B.
4. Find the equilibrium price as a function of A and B.
5. Let's use some numbers. Suppose A = 10 and B = 2. Solve for the profit-maximizing
quantity and price.
6. Using A = 10 and B = 2, draw a demand curve and a marginal revenue function as well as
marginal cost. Shade the deadweight loss. Also label clearly the profit-maximizing quantity
and price chosen by the monopolist.
7. What would have been the competitive equilibrium price and quantity (hint: equate MC and
the demand function)? Label the competitive equilbrium point. Also compute the size of the
deadweight loss due to inefficiency casued by the monopolist behavior.
