摘要：I consider a war of attrition game with complete information in which N ≥ 2 players compete for N−K prizes. When K=1, the game typically has a nondegenerate equilibrium in which the players’strategies follow exponential distributions. The duration of the game tends to increase with the number of players. Given the number of players, the expected duration is linear to the harmonic mean of the players’‘strengths’. The equilibrium surely exists when N = 2. When N ≥ 3, it exists only when the weakest player is not too weak compared to the average. If it exists, the equilibrium is unique under some conditions. When K ≥ 2, the game typically has nondegenerate equilibria in which K−1 players give up immediately. The model can be extended to the case with interdependent valuations or ‘defeats’. An application of the model is on an N-bidder all-pay auction with ascending bids.
