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.)

a. Consider the game faced by the British and Dutch managers when both are given contracts that compensate them with (1)/(2) of 1% of revenue. The strategic form game is shown. Find the Nash equilibria. b. Now consider the game between the British and Dutch shareholders as to what kind of contracts to give their managers. Assume that they simultaneously choose between a contract that gives the manager 1% of profit and one that gives him (1)/(2) of 1% of revenue. Assume, as before, that the shareholders’ payoff is profit (and we ignore the trivial amount that they pay to their managers). After a pair of contracts is selected, the two contracts are revealed to both managers, and the managers then choose between supply levels of low, moderate, and high. Find all SPNE.

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.

16-1. Two equal sized newspaper have an overlap in circulation of 10% (10% of the subscribers subscribe to both newspaper). Advertisers are willing to pay $10 to advertise in one newspaper but only $19 to advertise in both , because they’re are unwilling to pay twice to reach the same subscribers. What’s the likely bargaining negotiation outcome if the advertisers bargain by telling each newspaper that they’re going to reach an agreement with the other newspaper so the gains to reaching agreement are only $9? Suppose the two newspaper merge. What is the likely post merger bargaining outcome?

Suppose Fiat recently entered into an Agreement and Plan of Merger with Case for $4.3 billion. Prior to the merger, the market for four-wheel-drive tractors consisted of five firms. The market was highly concentrated, with a Herfindahl- Hirschman index of 2,650. Case's share of that market was 18 percent, while Fiat comprised just 9 percent of the market. If approved, by how much would the postmerger Herfindahl-Hirschman index increase? Based only on this information, is the Justice Department likely to challenge the merger according to the Horizontal Merger Guidelines? Possibly - but other factors will be considered Yes Ο NO
