There are situations in which competitors ally to pursue a common objective. This simultaneous presence of cooperation and competition is called coopetition and we study it theoretically and experimentally in a group contest setup. More concretely, we analyze a group contest with a new sharing...

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...

Two players with independent private values compete for a prize in an all-pay contest. Before the contest, each player can spy on the opponent by privately acquiring a costly, noisy, and private signal about his private value. In a symmetric equilibrium of the contest where players spy on each...

This paper introduces a class of contest models in which each player decides when to stop a privately observed Brownian motion with drift and incurs costs depending on his stopping time. The player who stops his process at the highest value wins a prize. We prove existence and uniqueness of a...

A contest is a situation in which individuals expend resources in order to win valuable prize(s). 'Sabotage' is a deliberate, and often costly and illegal, act of damaging a rival's likelihood of winning the contest. It is done by exerting resources to negatively influence the effectiveness of a...
