a monopolist faces a demand curve Qd- 120-2p and has costs given by C(Q)=20Q+100 (marginal cost is constant at $20)
a. What is the optimal Price and Quantity for this monopolist?
b. Calculate the monopolist''s profits.
c. Had this monopolist been acting as a perfectly competitive firm, what would have been the market price, and what quantity would the firm have chosen?
d. Graph the (inverse) demand curve, marginal revenue curve and marginal cost curve. Identify the monopolist''s profit maximizing price and quantity, the price and quantity from the part C, and illustrate the area of efficiency loss (DWL) imposed due to monopoly power.
