Many economic, political and social environments can be described as contests in which agents exert costly efforts while competing over the distribution of a scarce resource. These environments have been studied using Tullock contests, all-pay auctions and rank-order tournaments. This survey...

This note introduces a model of contests with random noise and a shared prize that combines features of Tullock (1980) and Lazear and Rosen (1981). Similar to results in Lazear and Rosen, as the level of noise decreases the equilibrium effort rises. As the noise variance approaches zero, the...
