We consider imperfectly discriminating, common-value, all-pay auctions (or contests) where some players know the value of the prize, others do not. We show that if the prize is always of positive value, then all players are active in equilibrium. If the prize is of value zero with positive...

This paper studies an economic contest with identical prizes. We consider the effects of division of the contest. When the contest designer divides the contest symmetrically, each participant competes in each assigned division. The main result is that division is sometimes profitable for the...

We study two-sided matching contests with two sets, A and B, each of which includes a finite number of heterogeneous agents with commonly known types. The agents in each set compete in a lottery (Tullock) contest, and then are assortatively matched, namely, the winner of set A is matched with...

Perfectly discriminating contests (or all pay auction) are widely used as a model of situations where individuals devote resources to win some prize. In reality such contests are often preceded by investments of the contestants into their ability to fight in the contest. This paper studies a two...

I consider competitions in which, conditional on winning or losing, the effort exerted by a competitor does not necessarily decrease his payoff. This happens, for example, in competitions for promotions in which workers are intrinsically motivated, and in research and development races in...

This paper generalizes the results of Siegel (2009, 2010) to accommodate performance spillovers. More precisely, we show that, if for any player, spillover from other players' performance is independent of his own performance, and if the spillover enters any player's payoff in an additively...

This paper studies complete-information, all-pay contests with asymmetric players competing for heterogeneous prizes. In these contests, each player chooses a performance level or "score". The first prize is awarded to the player with the highest score, the second -- less valuable -- prize to...

This note studies contests in which multiple participants compete for two distinct prizes. The participants have distinct constant marginal costs, which are commonly known. We show that the contests have a unique Nash equilibrium, and we characterize the equilibrium payoffs and strategies in...

We consider contestants who must choose exactly one contest, out of several, to participate in. We show that when the contest technology is of a certain type, or when the number of contestants is large, a self-allocation equilibrium, i.e., one where no contestant would wish to change his choice...
