Joe and Rebecca are small-town ready-mix concrete duopolists. The market demand function is Qd = 10,000 – 100P, where P is the price of a cubic yard of concrete and Qd is the number of cubic yards demanded per year. Marginal cost is $25 per cubic yard. Suppose that Joe and Rebecca compete in quantities and competition in this market is described by Cournot model. What are Joe and Rebecca’s Nash equilibrium outputs? What is the resulting price? What do they each earn as profit? How does the price compare to the marginal cost?

Olivia is thinking about opening a new bakery (the entrant). There is already a bakery open in her neighborhood (the incumbent), and the owner of the incumbent bakery makes it clear that if Olivia enters the market, they will cut their prices in an attempt to drive the new bakery out of business. Based on the payoff matrix below, is the incumbent’s threat credible? That is, if Olivia opens a new bakery, will the incumbent actually lower their prices?
Note: the entrant chooses the row, the incumbent chooses the column

Yes, the threat is credible
b.

Consider the following Cournot model. • The inverse demand function is given by p = 30 –Q, where Q = q1 + q2. • Firm 1’s marginal cost is $6 (c1 = 6). Firm 2 uses a new technology so that its marginal cost is $3 (c2 = 3). There is no fixed cost. • The two firms choose their quantities simultaneously and compete only once. (So it’s a one-shot simultaneous game.)
d. Suppose there is a market for the technology used by Firm 2. What is the highest price that Firm 1 is willing to pay for this new technology?
e. Now let’s change the setup from Cournot competition to Bertrand competition, while maintaining all other assumptions. What is the equilibrium price?
f. Suppose the two firms engage in Bertrand competition. What is the highest price that Firm 1 is willing to pay for the new technology?

- Two firms in a duopolistic industry produce outputs 91 and q₂ at a constant and equal marginal cost of 2. The inverse market demand curve is given by p = 14 - (q_{1} + q_{2}) for price per unit p. Consider the Stackelberg duopolistic game where firm 1 is an incumbent monopoly acting as a leader and firm 2 is a potential entrant that faces a fixed cost F = 16 if it enters and competes in the market. What is the outcome of the Stackelberg leader-follower game in this case? 92 =arrow_forwardThree firms produce identical products and compete in a market where the inverse demand function is P(q1, q2, q3) = 78 − q1− q2− q3. Each has a per-unit cost of 14 and zero fixed cost. They simultaneously choose quantities. In scenario (a), find the Nash equilibrium of this game and let A = firm 2's profit in the Nash equilibrium. In scenario (b), assume that the firms form a cartel, i.e., they act as a monopoly and split the profit evenly. If the total quantity produced by the cartel is Q, then the inverse demand is P(Q) = 78 - Q. Let B = firm 2's profit in the cartel. Calculate the value of A - B and enter your answer in the box below. Please round your answer to 3 decimal places (e.g., write 4/3 as 1.333).arrow_forwardFirm A Firm B Low Price High Price Low Price (2, 2) (10, −8) High Price (−8, 10) (15, 15) Suppose the game is infinitely repeated, and the interest rate is 10 percent. The firms are allowed to collude and make joint decisions. Both firms agree to charge a high price, provided no player has charged a low price in the past. This collusive outcome will be implemented with a trigger strategy that states that if any firm cheats (by charging a low price), then the agreement is no longer valid and each firm may make their own independent decisions. Will the trigger strategy be effective in implementing the collusive agreement? Please explain and show all necessary calculations.arrow_forward
- You are considering entering a market serviced by a monopolist. You currently earn £0 economic profits, while the monopolist earns £5. If you enter the market and the monopolist engages in a price war, you will lose £5 and the monopolist will earn £1. If the monopolist doesn't engage in a price war, you will each earn profits of £2. (a) Write out the extensive form of the above game? (b) Are there any Nash equilibria for the game? Explain. (c) Is there a subgame perfect equilibrium? Explain. (d) If you were the potential entrant, would you enter? Explain why or why not.arrow_forwardWhich of the following is FALSE for the grim trigger strategy and the infinite horizon repeated Prisoner's Dilemma game illustrated above? A. In the grim trigger strategy profile, if a player chooses D in a period, then both players chooses D forever after that period B.

- Consider a duopolistic market in which the two identical firms compete by selecting their quantities. The inverse market demand is P(Q) = 210−Q and each firm has a marginal cost of $15 per unit.

Assume that total demand for the chips is fixed and that each firm charges the same price for the chips. Each firm’s market share and profits are a function of the magnitude of the promotional campaign used to promote its version of the chip. Also assume that only two strategies are available to each firm: a limited promotional campaign (budget) and an extensive promotional campaign (budget). If the two firms engage in a limited promotional campaign, each firm will earn a quarterly profit of $14 million. If the two firms undertake an extensive promotional campaign, each firm will earn a quarterly profit of $11 million. With this strategy combination, market share and total sales will be the same as for a limited promotional campaign, but promotional costs will be higher and hence profits will be lower.…arrow_forwardThree oligopolistic firms ("1", "2" and "3") conduct quantity competition in a certain market. The interactions between them take place as follows: firm 1 defines its production quantity, which is immediately observed by firms 2 and 3; then, firm 2 makes its decision on how much it will produce, and only after observing the decisions of firms 1 and 2 does firm 3 finally make its respective choice. Furthermore, the total costs of firms 1, 2 and 3 correspond respectively to c₁(q₁) = 10q₁, c₂(q₂) = 8q₂ and c₃(q₃) = 2q₃, and the firms face a (inverse) demand given by p(Q) = 110 - Q (where Q = q₁ + q₂ + q₃). Based on this information, determine what will be the total amount produced by the firms in the (single) ENPS for that game. (Note: the correct answer is an integer.)arrow_forward
- Burger Doodle, the incumbent firm, wishes to set a limit price of $8 (rather than the profit-maximizing price of $12) to prevent Designer Burger from entering its profitable market. The game tree above shows the payoffs for various decisions. Burger Doodle makes its pricing decision, then Designer Burger decides whether to enter or stay out of the market. If Designer Burger chooses to enter the market, then Burger Doodle may or may not decide to accommodate Designer’s entry by changing its initial price to the Nash equilibrium price of $10. If Burger Doodle canNOT make a credible commitment to maintain its initial price should Designer Burger decide to enter the market, then Burger Doodle will set price equal to $________ at decision node 1 and the outcome _____________(is, is not) a Nash equilibrium.arrow_forwardSeveral firms collude in an oligopoly where the Industry Supply is given by QS = 6 - 5P and Industry Demand is given by, QD = 5P – 5.
