3. (35 points Suppose that there are K( 3) firms operate in a market with demand function given by P(Q) = 100-Q, where Q=91 +92 + ... +2K, and qi is the quantity produced by firm i. Each firm has a constant marginal cost of production, c = 10, and no fixed cost. The firms choose their quantities dynamically as follows: Firm 1, which is the industry leader, chooses qı € (0, 100). All other firms i = 2,..., K...
Two firms sequentially choose quantities q1, q2 to produce an identical good. First, firm 1 chooses q1, then firm 2 chooses q2. The price per unit in the market is p(q1, q2) = 1 − (q1 + q2). Assume that both firms have a constant marginal cost of zero. Both firms seek to maximize their profit. a. Formulate this story as an extensive form game b. Find all Nash equilibria of this game. c. Find the Subgame Perfect Nash equilibria...

There is no discounting in this problem and so a player’s payoff
in this repeated game is the sum of her payoffs in the two plays of
the stage game.

2. Consider a Cournot dupoly, but assume that demand is p(q) = 12 – 9 (ignoring non-negativity) and and unit cost c= 3. Again, firms simultaneously pick quantities qı > 0 and q2 > 0 and the price is set to clear the market given the quantities chosen. 1. Write down the optimization problems that define the best responses, solve explicitly for the best response functions, and find all Nash equilibria. 2. Formulate the problem for a cartel that maximizes...
There are three firms: firm 1, firm 2 and firm 3. Each firm i chooses the level of production qi. The market price is determined by market demand: p = 24 – 91 - 92 - 43. And the marginal cost of production is zero. (a) Suppose firm 1 moves first, then firm 2 moves and finally firm 3 moves. Each firm can observe the previous firms' production strategies. Find all the subgame perfect equilibria. (b) Suppose firm 1 moves...

2. Two firms produce homogeneous products. Market demand is given by Q = 40-P, and each firm faces a marginal cost of production of 4 per unit The timing of the game is as follows. In Period 1, firm 1 chooses the quantity q it will sell. In Period 2, firm 2 (who observed firm 1s choice in period 1) chooses whether or not to enter the market. If firm 2 chooses to enter it must pay an entry fee...
Two profit-maximizing firms compete in a market. Firm 1 chooses quantity qı > 0 and Firm 2 chooses quantity 42 > 0. The market price is: p(91,92) = 8 - 2q1 - 42. The cost to Firm 1 of producing qi is C1 = 41. The cost to Firm 2 of producing 92 is C2 = 42 + 42. a.) * Calculate the best-response function for each firm. b.) Suppose the two firms choose their quantities simultaneously. What is the...
Suppose that the inverse market demand for a commodity is given by P = 240 Q The cost curves of the three firms which could serve this market are TC,(a) 30q +300 and TC2() (d) Suppose that firms engage in Stackelberg rather than Cournot competition. Firm 1 moves first by choosin its output level. After Firm 1 has chosen its output level, Firm 2 observes ql and chooses its output leve Find the subgame-perfect Nash equilibrium of the Stackelberg game....
6. Entry Deterrence 2: Consider the Cournot duopoly game with demand p= 100 - (qı+q2) and variable costs c;(q;) = 0 for i € {1, 2}. The twist is that there is now a fixed cost of production k > 0 that is the same for both firms. Assume first that both firms choose their quantities simultaneously. Model this as a normal-form game. b. Write down the firm's best-response function for k = 1000 and solve for a pure-strategy Nash...
