报告题目：N-Player War of Attrition with Complete Information

摘要：This paper considers a non-degenerate war of attrition in which N>2 heterogeneous player compete for N-k prizes. The equilibrium mixed strategies feature exponential distributions. Except in two-player case, such an equilibrium may not exist. But as long as it exists, the weaker players play the game more patiently than the others, and therefore are more likely to win. All players, including the strong ones, obtain zero expected payoffs. Under mild condition, the non-degenerate mixed strategy equilibrium is unique when it exists. When k>1, i.e., more than one players must concede before the game ends, k-1 of the players concedes at the very beginning of the game. The model can be extended to the cases when the winners’ payoffs depend on which players concede, and that when the players face the risks of “defeat.”
