Consider a game in which we add an extra stage to the standard Bertrand model of price competition where firms choose a capacity level. Consider a market with two firms. In the first stage, each firm chooses a production capacity level q₁ at a cost of 0.25 per unit of capacity, where 0 ≤q¡ ≤ 1. In the second stage, the firms observed each other's capacity and respond by competing over prices. Once capacity is decided, the firms can produce up to that capacity with zero marginal cost. Each firm faces a demand of p = 1 Q and choose prices simultaneously in the second stage, and sales are distributed as in the standard Bertrand model. (a) Verify and explain that in the second stage, both firms will set a common price p₁ =p² =p* = 1- q1 – q2. (b) In the first stage, each firm simultaneously and independently chooses its capacity, q₁. Find the equilibrium capacities and price. (Hint: both firms anticipate equilibrium price p* in the second stage) (c) 2 Compare your results in (b) if both firms only compete in choosing q as in the standard Cournot model with the inverse market demand p = 1 - Q and identical marginal cost of 0.25 per unit of output.

QUESTION 13 Consider a market where two firms (1 and 2) produce differentiated goods and compete in prices. The demand for firm 1 is given by D₁(P₁, P2) = 140 - 2p1 + P2 and demand for firm 2's product is D2 (P1, P2) 140 - 2p2 + P1 Both firms have a constant marginal cost of 20. What is the Nash equilibrium price of firm 1? (Only give a full number; if necessary, round to the lower integer; no dollar sign.)
There are two firms in the market. Denote the price and the quantity of firm j by p; and q; , respectively. Those two products are differentiated and the demand system is given by 91 = 100 – 2p1 + P2 92 = 100 + pi – 2p2 For simplicity, assume zero production costs, meaning that profit is equal to revenue. Consider the two-stage game in which firm 1 decides the price first and then firm 2 choose its price after observing firm 1's price. If firm 1's price is 24, what is the best response price of firm 2? Report only the value . Answer:
Consider a Bertrand oligopoly where two firms (Firms 1 and 2) sell goods that are imperfectsubstitutes and compete by choosing prices simultaneously. Their market demands areq!= 1,200 − 3/2p!+ 3/2p", q"= 800 − 2p"+ 1/2p!For simplicity, assume the marginal cost is zero for both firms (MC!= MC"= 0). Find the bestresponse curve of each firm. Which of the following alternatives is correct?(a) Firm 1’s best response curve is p!= 400 + 0.5p"(b) Firm 2’s best response curve is p"= 400 + 0.5p!(c) Firm 1’s best response curve is q!= 45 − 0.5q"(d) Firm 2’s best response curve is q"= 200 + 0.8p! Then, find the optimal price and quantity of each firm.Hint: Start by finding the Nash equilibrium, that is, the combination of mutual best responses.Which of the following alternatives is correct?(a) For firm 1, p!= $1,600/3 and q!= 800/3(b) For firm 1, p!= $800 and q!= 1,600/3(c) For firm 2, p"= $800 3⁄ and q"= 1,600/3(d) For firm 2, p"= $1,600 and q"= 800 key: !=1 "=2
Suppose two firms face market demand of P=150-Q, where Q = q1+ q2. Both firms have the same unit cost of C, which C=28. Assume the firms compete a la Stackelberg. Firm 1 is the leader and Firm 2 is the follower in this market. a) What is the follower's total revenue function? b) Determine the equilibrium output level for both the leader and the follower. c) Determine the equilibrium market price. d) Determine the profits of the leader and the follower.
Consider a market in which there are two firms: A and B. Each firm produces a differentiated product and chooses its price. Assume that each firm can set price equal to $60 or $70. The payoffs associated with each set of prices are shown. If the firms choose price simultaneously, then the Nash equilibrium price for firm A is chooses price first and can commit to that price, then firm A will set its price equal to If firm A ○ A. $70; $60 B. $70; $70 ○ C. $60; $70 ○ D. $60; $60 Q Firm B's Price ✓ $60 $70 $1800 $1650 $60 $1800 $2250 Firm A's Price $2250 $2200 $70 $1650 $2200

The inverse market demand for fax paper is given by P=100-Q. There are two firms who produce fax paper. Firm 1 has a cost of production of C1= 15*Q1 and firm 2 has a cost of production of C2=20*Q2 a) Suppose that firm play a Stackelberg game. First firm 1 sets the quantity in t=1, then, knowing which quantityfirm 1 has set, firm 2 chooses the quantity in t=2. What are the Stackelberg quantities and prices? What arethe profits od firm 1 and 2? Compared to part a) which firm benefits and which firm loses?
Two firms compete in a market to sell a standardized product and the inverse demand in the market is P = 400 – Q where Q = Q1 + Q2. The cost functions are: C1(Q1) = 8Q1 and C2(Q2) = 36Q2. If this market is characterized by a Stackelberg oligopoly, what is the optimal amount for the leader (firm 1) to produce?
Q4. Suppose two firms (firm 1 and firm 2) sell differentiated products and compete by setting prices. Firms have a zero cost of production. The demand functions are q₁ = 1- P₁ + P₂ and q2 = 1-P₂ + P₁ What will be the price charged by each firm in a simultaneous-move game?

The following market is a duopoly populated only by the companies Alpha and Beta. The pay-off matrix immediately below shows the combinations of pricing strategies available to the two companies. The numbers represent millions of dollars in profit. (The negative sign indicates a loss.) Assuming Beta has a first mover advantage, in a one-shot game, what is liekly to be the Nash equilibrium? Explain your answer. Alpha High price Low price High price 250, 200 200, 100 Beta Low price 50, 150 100, 250
Consider a strategic interaction between firms 1 and 2. In Stage 1, firm 1 chooses the level of advertising a > 0. In stage 2, firm 2 learns about firm 1's amount of advertising a. Subsequently, firms 1 and 2 compete in a Cournot fashion. That is, firms 1 and 2 simultaneously and independently choose their outputs: q1 and q2, where qi denotes the output of firm i = 1,2. The price that the consumers are willing to pay for the product produced by the two firms, or the inverse aggregate demand function, is given by 6a - q1 - q2. Firm 1's advertising cost is a3. Both firms have zero production costs. Both firms maximize their individual profits (equal to the total revenue minus total cost). In the unique subgame perfect equilibrium of the game, the two firms will choose the following strategies: a. Firm 1 will choose strategy (a = 3, q1 = a/3) while firm 2 will choose strategy q2 = a/3 b. Firm 1 will choose strategy (a = 1, q1 = 16/3 ) while firm 2 will choose strategy q2 = 16/3 c. Firm 1…
