In Problem 5, the market demand decreases and the demand schedule becomes: If firms have the same costs set out in Problem 5, what is the market price and the firm’s economic profit or loss in the short run? Problem 5 The market for paper is perfectly competitive and 1,000 firms produce paper. The table sets out the market demand schedule for paper. The table in the next column sets out the costs of each producer of paper. Calculate the market price, the market output, the quantity produced by each firm, and the firm’s economic profit or loss.
Suppose the competitive market price is $60, and a competitive firm’s total costs = q^2 - 6q + 990 and marginal cost = 2q - 6.
a. Solve for the profit-maximizing (or loss minimizing) quantity (q*).
b. What is the market equilibrium price?
c. Should the competitive firm produce q*? Explain why using one of the four key questions and solutions.
d. Does the competitive firm make a profit? Explain why using one of the four key questions and solutions.
e. How much profit (or loss) does the competitive firm make?
Question 23 A competitive firm has a total cost function in dollars of the form C(q)= 100–4q + q^2, where q is output. Suppose the market price is $10 per unit of output. What is the firm’s short run point elasticity of supply? a) 20/7 b) 5/7 c) 10/7 d) 0.5 e) 2
