The inverse demand function a monopoly faces is P = 100 − Q. The firm’s cost curve isTC(Q) = 10 + 5Q
(f) (4 points) For what value of fixed costs, does the monopolist break even?
(g) (4 points) For what value of fixed costs, would be monopolist find it optimal to shut down in the short-run?
(h) (4 points) For what value of fixed costs, would be monopolist find it optimal to shut down in the long-run?
(i) (4 points) What is the value of Lerner Index at the profit maximizing level of output?
f) at break even, TR = TC
(100-Q)Q =10+5Q
Q2 -95Q+10=0
This equation is solved at Q=0 or Q =95
TC at Q=0 is 10 and TC at Q=95 is 485.
g) for shut down in the short run, the TR must cover the variable costs only hence
100-Q= 5
Q =95 The cost will be 485
h) for shut down in long run, revenue must cover all costs therefore TR=TC, Q= 0/95
TC= 10/495

You are the manager of a monopoly that faces an inverse demand curve P = 100 - 10Q and has constant average and marginal costs of $20 per unit. The government is considering legislation that would regulate your firm's price at $20 per unit. (a) What is the profit-maximizing quantity at the regulated price? Please show your calculations. (b) What is the profit (or loss) at the regulated price or quantity? Please show your calculations. (c) Can this firm continue...
1. (25 points) Suppose that a monopolist faces the inverse demand curve: P 100-Q and produces goods at a marginal cost of $5. Finally assume that the firm incurs no fixed costs A. Suppose the monopolist lowers the price from $90 to $89. Explain why the firm's marginal revenue is less than the price of the 11th unit sold, $89 (do not answer this question by providing a mathematical equation). B. At what price will the monopolist maximize its profit?...
