We investigate situations in which players make costly contributions as group mem- bers 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...

We analyze a group contest in which n groups compete to win a group-specific public good prize. Group sizes can be different and any individual player may value the prize differently within and across groups. Players expend costly efforts simultaneously and independently. Only the highest effort...

We find the sufficient conditions for the existence of multiple equilibria in Tullock-type contests and show that asymmetric equilibria may arise even under symmetric prize and cost structures. We also identify contests in the literature where multiple equilibria exist under reasonably weak...

We examine conditions under which a platform firm can exclude rivals by bundling a product that some on one side of the market regard as essential with its platform, and pursue implications for market performance. We show that the impact of an exclusive dealing contract between the upstream firm...

We analyze a group all-pay auction with a group specific public good prize in which one group follows a weakest-link and the other group follows a best-shot impact function. This type of game depicts situations in which the best-shot group is an attacker and the other group is a defender. We...

We investigate the effects of the availability of resources that can be expended in conflict on conflict intensity. We run a between-subjects Tullock contest in which we vary the contest budget from Low to Medium to High, while keeping the Nash equilibrium bid the same. We find an `inverted...

This study analyzes a group contest in which one group (defenders) follows a weakest link whereas the other group (attackers) follows a best-shot impact function. We fully characterize the equilibria and show that with symmetric valuation the equilibrium is unique up to the permutation of the...

Contests are ubiquitous in economic and political settings. Contest designers often use tools to make a contest among asymmetric contestants more even, in order to either elicit higher effort levels, or for ethical reasons. Handicapping - in which stronger participants are a priori weakened - is...

It is observed in neuroscience, economics and psychology experiments that the presence of an image of a pair of eyes may result in higher level of altruistic behavior by subjects. It is hence concluded that the eye-image serves as a `social Êcue'. We test this against an alternative hypothesis...

We consider a multi-winner nested elimination contest in which losers are sequentially eliminated to attain the set of winners. This is a variant of a widely used mechanism introduced by Clark and Riis (1996) that allows one to select the winners sequentially. We show that the nested elimination...
