Standard theoretical prediction is that rational economic agents participating in rent-seeking contests should engage in socially inefficient behavior by exerting costly efforts. Experimental studies find that the actual efforts of participants are significantly higher than predicted and that...

The standard theoretical description of rent-seeking contests is that of rational individuals or groups engaging in socially inefficient behavior by exerting costly effort. Experimental studies find that the actual efforts of participants are significantly higher than predicted in the models...

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...

Violence and coercion are key to understanding economic and social interactions in any society. This premise was used by North et al. (2009) to distinguish three `patterns of social organization' that societies have used to solve the problem of violence. We model one of these, the `limited...

We analyze the determinants of tacit collusion in an infinitely repeated contest with noise in the contest success function. Sustaining collusion via Nash reversion strategies is easier the more noise there is, and is more difficult the larger is the contest's prize value. An increase in the...

Despite the wide occurrence of ties in a variety of contest settings, the strategic interaction that arises when ties are treated as viable outcomes has received little attention. Building on recent theoretical work, we experimentally examine an extension of the canonical two-player all-pay...

Violence is key to understanding human interaction and societal development. The natural state of societal organization is that a subset of the population, capable of mustering organized large-scale violence, forms an elite coalition that restrains both violence and coercive appropriation. We...

We consider a general class of imperfectly discriminating contests with privately informed players. We show that findings by Athey (2001) imply the existence of a Bayesian Nash equilibrium in monotone pure strategies.

We consider a variant of the Tullock rent-seeking contest. Under symmetric information we determine equilibrium strategies and prove their uniqueness. Then, we assume contestants to be privately informed about their costs of effort. We prove existence of a pure-strategy equilibrium and provide a...

We investigate situations in which players make costly contributions as group members in a group conflict, and at the same time engage in contest with fellow group members to appropriate the possible reward. We introduce within group power asymmetry and complementarity in members' efforts, and...
