Two faculty members in the Economics department both want to recruit a top graduate student to their department. Either faculty member can ensure the student will accept the offer by getting on the phone and shamelessly promoting the graduate program. However, there is some cost to making this call. Assume the payoffs can be represented as follows:
Player 2 | |||
Call | Dont Call | ||
Player 1 | Call | 1-,1- | 1-, 1 |
Dont Call | 1,1- | 0,0 |
where 1 and 2 represent the costs for player 1 and 2 respectively. Assume the faculty members choose their actions simultaneously and the faculty have private information about their costs of making the call. That is, faculty mem- ber i knows i, and believes that j is a random draw from a uniform distribution on [c,c]. Faculty member is belief about j is commonly known. (a) Find the normal form representation of this game of incomplete information. (b) Now imagine that 1 and 2 are independent random draws from a uniform distribution on [0,2]. Find a symmetric BNE in cutoff strategies.1 (c) The equilibrium outcome found in (b) is inefficient in several ways. (i) Explain why there is under-investment. (ii) Explain why there is misscoordination between faculties.
