Transcribed Image Text: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.
