This paper finds an empirical evidence that al Qaeda behaves as a contest organizer rewarding a prize to candidate extremist groups. Would-be terrorists must then compete with each other to prove their commitment and ability. Hence to maximize their own probability of winning the prize, each...

This short paper aims to find an empirical evidence that al Qaeda behaves as a contest organizer rewarding an indivisible prize – namely, official membership and economic rewards – to candidate extremists groups. Would-be terrorists must then compete with each other to prove their commitment...

Using a two-player Tullock-type contest we show that intuitively and structurally different contests can be strategically equivalent. Strategically equivalent contests generate the same best response functions and, as a result, the same equilibrium efforts. However, strategically equivalent...

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...

We find the sufficient conditions for the existence of multiple equilibria in Tullock-type contests, and show that asymmetric equilibria arise even under symmetric prize and cost structures. We then present existing contests where multiple equilibria exist under reasonably weak conditions.

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...

We provide an overview of experimental literature on contests and point out the two main phenomena observed in most contest experiments: (i) overbidding relative to the standard Nash equilibrium prediction and (ii) heterogeneous behavior of ex-ante symmetric contestants. Based on the sample of...

This article examines behavior in the two-player, constant-sum Colonel Blotto game with asymmetric resources in which players maximize the expected number of battlefields won. The experimental results support the main qualitative predictions of the theory. In the auction treatment, where winning...
