7. Based only on the knowledge that the premerger market share of two firms proposing to merge was 20 percent each, an economist working for the Justice Department was able to determine that, if approved, the postmerger HHI would increase by 800. How was the economist able to draw this conclusion without knowledge of the other firms' market shares? From this information, can you devise a general rule explaining how the Herfindahl-Hirschman index is affected when exactly two firms in the market merge? (Hint: Compare & + with (a + b)².)

3. We consider the following situation between 2 firms. Firm A (the "acquirer") would like to take over firm T (the "target"). It does not know firm I's value; it believes that this value, when firm T is controlled by its own management, is at least $0 and at most $100, and assigns equal probability to each of the dollar values in this range (we assume that the value is distributed uniformly on this interval). Firm T will be worth 50% more under firm A's management than it is under its own management. Suppose that firm A bids p to take over firm 7; and firm T is worth x (under its own management). Then if T accepts A's offer, A's payoff is 2x-p and T's payoff is p; if T rejects A's offer, A's payoff is 0 and T's payoff is x. (a) Formalize this situation as a Bayesian Game (b) Find the Bayesian Nash Equilibria of this game.
3. Breakdown of a cartel agreement Consider a town in which only two residents, Gregor and Haidy, own wells that produce water safe for drinking. Gregor and Haidy can pump and sell as much water as they want at no cost. For them, total revenue equals profit. The following table shows the town's demand schedule for water. Price (Dollars per gallon) 4.80 4.40 4.00 3.60 3.20 2.80 2.40 2.00 1.60 1.20 0.80 0.40 0 Quantity Demanded (Gallons of water) 0 35 70 105 140 175 210 245 280 315 350 385 420 Total Revenue (Dollars) 0 $154.00 $280.00 $378.00 $448.00 $490.00 $504.00 $490.00 $448.00 $378.00 $280.00 $154.00 0 Suppose Gregor and Haidy form a cartel and behave as a monopolist. The profit-maximizing price is $ output is S per gallon, and the total gallons. As part of their cartel agreement, Gregor and Haidy agree to split production equally. Therefore, Gregor's profit is , and Haidy's profit is $ Suppose that Gregor and Haidy have been successfully operating as a cartel. They each charge the…

5. Two firms compete repeatedly in a market of homogeneous goods. Each year, the firms can choose to charge a low or high price. The following payoff table summarizes their payoffs each year. The competition goes on indefinitely. Let 5 E (0, 1) denote the discount factor for both firms. Firm 2 Low High Low 0, 0 5, 0 Firm 1 High 0, 5 4, 4 Consider an n-period punishment trigger strategy s: • Play "High price" in the first stage. • In stage t> 2, if some player deviated to "Low price" in the last period when he is supposed to play "High price", then play "Low price" for n periods and then restart the game. In other words, after playing "Low price" for n periods, play "High price" in the next stage as if it is the first stage of the game. Otherwise, play "High price". Find the necessary and sufficient condition on & for (s, s) to be an SPE. A sufficiently simplified inequality will do.

5.4 Food service firms buy meat, vegetables, and other foods and resell them to restaurants, schools, and hospitals. US Foods and Sysco are by far the largest firms in the indus- try. In 2015, these firms were attempting to combine or merge to form a single firm. A news story quoted one res- taurant owner as saying: "There was definite panic in the restaurant industry... when the merger was announced. They know they're going to get squeezed." a. Analyze the effect on the food service market of US Foods and Sysco combining. Draw a graph to illustrate your answer. For simplicity, assume that the market was perfectly competitive before the firms combined and would be a monopoly afterward. Be sure your graph shows changes in the equilibrium price, the equilibrium quantity, consumer surplus, producer surplus, and deadweight loss. b. Why would restaurant owners believe they would be "squeezed" by this development?
