L 8. Two firms, the only firms in the market, sell the same product and have the same marginal cost. They realise they would be better off if they didn't compete with each other. They enter an alternating offers bargaining game to decide how they will divide the monopoly profit, n. They have three periods to come to an agreement. If no agreement is reached after three periods, the firms will compete simultaneously in prices. The firms toss a coin to decide who makes the first offer in the bargaining game. Firm 1 wins and decides to go first. Each firm has a discount factor o. a) Draw the game tree. b) What is the subgame perfect equilibrium when o = 0.5?

In a Şweezy Oligopoly (Kinked-demand) model, price stability can exist without collusion in an oligopoly. Two firms "squabble" over a market. In such a model, whenever the price of one firm (Firm-ABC) increases, the other firm's price remained constant. On the other hand, 4.1. whenever the price of Firm-ABC decrease, its rival would reduce the price too to maintain its market share. Suppose that a Firm-ABC's demand curve (and its marginal curve) is represented by the Kinked-demand curve given in the figure below. Also, cost information is provided in the figure: Cost, P ATC 'MC 20 18 10 7 5 Deamnd MR 100 200 a. How much output should Firm-ABC produce to maximize its profit? Why? b. At what price should Firm-ABC sell to maximize profit? Why? c. What is the total cost of Firm-ABC when it produces 200 units? [Show your steps] d. Calculate the maximum profit of Firm-ABC?

Suppose that there are two firms producing a homogenous product and competing in Cournot fashion and let the market demand be given by Q = 240- Assume for simplicity that each firm operates with zero total cost. Find each firm's Cournot Nash equilibrium profit for each firm. $21600 O $19200 O $18000 O $16000
4. Farmer Andy and Farmer Betty are the only two farmers that grow heirloom tomatoes for sale at the local farmer's market and compete as Cournot duopolists. The inverse demand curve for heirloom tomatoes at the market is P = 140 - 5Q where P is the %3D price per pound of tomatoes and Q is the number of pounds of tomatoes in hundreds per week; Q = qA + qB. Both Andy and Betty have a cost of growing tomatoes of w = 10, r = 20, and both have K = 1 in the short run. They both have a production function of q = L0.5KO.5. They will both earn profits of --.
4. Two Stackelberg-competitors with no costs face the common market demand curve P=30−Q, where Q is the combined output of both firms. Firm 1, the leader, picks its output first. Then Firm 2, the follower, picks its output. How much output does Firm 2 produce in their sequential-move game? a) 3 units. b) 15 units. c) 15/2 units. d) 30 units.

Consider a oligopoly with two firms. Each firm has constant marginal cost of 3 dollar per unit and zero fixed costs. Suppose the market demand curve is P = 15-Q, where Q=Q1+Q2 is the sum of the quantities produced by both firms. Suppose each firm can produce either 1, 2, 3, or 4 units. Which of the following is an optimal collusive outcome for the firms? O Each firm produces 2 units. Each firm produces 4 units. O Each firm produces 3 units. O Each firm produces 1 unit.

Suppose that an oligopolistic is charging $21 per unit of output and selling 31 units each day. What is its daily total revenue? Also suppose that previously it had lowered its price from $21 to $19, rivals matched the price cut, and the firmâ€™s sales increased from 31 to 32 units. It also previously raised its price from $21 to $23, rivals ignored the price hike, and the firmâ€™s daily total revenue came in at $482. Which of the following is most logical to conclude? The firmâ€™s demand curve is (a) inelastic over the $21 to $23 price range, (b) elastic over the $19 to $21 price range, (c) a linear(straight) down sloping line, or (d) a curve with a kink in it?
