This paper analyzes coalition formation in a model of contests with linear costs. Agents first form groups and then compete by investing resources. Coalitions fight for prizes that are assumed to be subject to rivalry, so their value is non-increasing in the size of the group. This formulation...

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...

This paper presents an axiomatic characterization of difference-form group contests, that is, contests fought among groups and where their probability of victory depends on the difference of their effective efforts. This axiomatization rests on the property of Absolute Consistency, stating that...

This paper considers a public good game with heterogeneous endowments and incomplete information affected by extreme free-riding. We overcome this problem through the implementation of a contest in which several prizes may be awarded. We identify a monotone equilibrium, in which the contribution...

This paper investigates the hypothesis that the objective function of economic agents is non-separable in economic incentives and social preferences. We study fixed-prize contests in a 2×2 experimental design, varying orthogonally the degree of competition of the incentive mechanism (all-pay...

This paper provides a direct test of the hypothesis that agents' objective functions are non-separable in economic incentives and social preferences. We study experimentally fixed-prize contests using a 2x2 design, varying orthogonally the degree of competition of the incentive mechanism...
