Question 3 Suppose that the market demand curve for golf balls is described by Q = 90 – 3P where Q is measured in kilos of balls. There are 2 firms that supply the market. Suppose first that golf balls produced by the 2 firms are identical. Firm 1 can produce a kilo of balls at a constant unit cost of $15 whereas firm 2 has a constant unit cost of $10. (a) Suppose firms compete in quantities. How much does each firm sell in a Cournot equilibrium? What is market price and what are the firms’ profits? Show your work. (b) Suppose firms compete in price. How much does each firm sell in a Bertrand equilibrium? What is market price and what are the firms’ profits? (c) Would your answer in (b) change if there were 3 firms , one with unit costs = $20 and 2 with unit costs = 10. Explain why or why not. (d) Would your answer in (b) change if firm 1’s golf balls were green and endorsed by Tiger Woods whereas firm 2’s are plain and white? Explain why or why not.

Two firms compete in a Bertrand setting for homogeneous products. The market demand curve is given by Q = 100 – P, where Q is quantity demanded and P is price. The cost function for firm 1 is given by C(Q) = 10Q and the cost function for firm 2 is given by C(Q) = 4Q. What is the Nash-Equilibrium price? What are the profits for each firm in equilibrium?

Consider a market with only two firms. Demand on this market is given by D(p)= 90 - 3p. Initially both firms have the same constant per-unit cost, specifically c1 = c2 = 20 . (a) What is the Nash equilibrium in this market if firms behave as Bertrand competitors? How much does each firm produce, what price do the firms charge, and what are their profits? (b) Now suppose that firm 1 acquires a new production technique that lowers its...

Consider the market for electricity in New York State. Suppose that the demand for electricity is given by Q=16-0.2P (P=80-5Q) where Q is measured in billions of kwh and P is measured in cents. The marginal cost of producing electricity in NYS is MC=5+Q. Suppose that there are three firms in this market who are competing on the wholesale market by choosing prices (Bertrand Competition). Firm 1 has a MC=15, Firm 2 has a MC=12, and Firm 3 has a...

24. Cournot duopolists face a market demand curve given by P = 90 - Q where Q is total market demand. Each firm can produce output at a constant marginal cost of 30 per unit. There are no fixed costs. Determine the (1) equilibrium price, (2) quantity, and (3) economic profits for the total market, (4) the consumer surplus, and (5) dead weight loss. 25. If the duopolists in question 24 behave according to the Stackelberg Leader-Follower model, determine the...
