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...

I analyse a group contest in which groups decide over two dimensions of membership-exclusivity: whether a member is allowed to join the group at all, and whether this member is allowed to join another group as well. If the prize is mostly private, group leaders do not offer membership in...

This paper considers rent-seeking games in which a small percentage change in a player's bid has a large percentage impact on her odds of winning, i.e., on the ratio of her respective probabilities of winning and losing. An example is the Tullock contest with a high R. The analysis provides a...

This paper provides a different approach to establish the uniqueness of equilibrium in Tullock con- tests between two players with asymmetric valuations, when the discriminatory power r is between 1 and 2. Our result complements that of Ewerhart (2017) in Ölling up the remaining gap in the...

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...

In this paper, a group contest is analyzed, where the groups are allowed to determine their sharing rules either sequentially or simultaneously. It is found that in case the more numerous group determines its sharing rule prior to the smaller group, rent dissipation in the group contest is...

We model competing groups when players' values for winning are private information, each group's performance equals the best effort ("best shot") of its members, and the group with the best performance wins the contest. At the symmetric equilibrium of symmetric contests, increasing the number of...

Contests are situations in which a set of agents compete for a valuable object, rent or award. The present paper analyzes difference-form group contests, that is, contests fought among groups and where their probability of victory depends on the difference of their effective efforts. First, we...
