Consider a monopolistically competitive market with N firms. Each firm's business opportunities are described by the following equations:
Demand: Q=100/N-P
Marginal Revenue: MR=100/N-2Q
Total Cost: TC=50+Q2
Marginal Cost: MC=2Q
a. How does N, the number of firms in the market , affect each firms demand curve? Why?
b. How many units does each firm produce? (The answer to this and the next two questions depend on N)
c. What price does each firm charge?
d. How much profit does each firm make?
e. In the long run, how many firms will exist in this market?
a) Can the threat of a price war deter entry by potential competitors? What actions might a firm take to make this threat credible?
b)Why is the firm’s demand curve flatter than the total market demand curve in monopolistic competition? Suppose a monopolistically competitive firm is making a profit in the short run. What will happen to its demand curve in the long run?
Assume the figure on the right shows the cost structure for a monopolistically
competitive firm selling a particular brand of shoes. MC is the marginal cost curve
and AC is the average cost curve.
If this firm produces 2 thousand pairs of shoes, does it minimize average cost?
How much more would they need to produce to reach minimum average cost?
The firm needs to produce an additional thousand pairs of shoes to reach
minimum average cost. (Enter your response as an integer.)

- Exercise A.4. A company operating in a market of monopolistic competition has an inverse demand curve for its product: P=315-3q, where q is the number of units produced of the good and P its price. The total cost of production of this company is given by: TC(q)=q²+75q+4000. a) To maximize profits, how many units of the good should you sell? b) What price should I charge? (c) What benefits would it reap? (d) Given the above information, how much would you have to reduce fixed costs for longterm equilibrium to occur?

Based upon these equations, answer the following questions: a. What quantity of output will the profit-maximizing firm produce in the market's long-run equilibrium? What price will the profit-maximizing firm establish in the long run? Explain how you know this firm is in long-run equilibrium? b. Determine the firm's allocatively efficient quantity of output? c.
