This paper deals with double lobbying: several bureaucrats participate in joint lobbying to get a high total departmental budget, but they also engage in antagonistic lobbying to reap as high a share of the total budget as possible. The antagonistic lobbying constitutes a contest among the...

We investigate situations in which players make costly contributions as group members 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...

Two types of political conflicts of interest pervade many of the world's societies. A horizontal conflict of interest arises when different constituencies support different policies, while a vertical conflict of interest emerges when those in charge of running the government acquire and retain...

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...

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 first formulates a model of how the politicians in a local government collectively lobby to raise intergovernmental grants to their local government. The model identifies a relationship between council size and grants received. I then study this relationship empirically using the...

Attorneys elected to the US Congress and to US state legislatures are systematically less likely to vote in favor of tort reforms that restrict tort litigation, but more likely to support bills that extend tort law than legislators with a different professional background. This finding is based...

Contests are well-established mechanisms for political lobbying, innovation, rentseeking, incentivizing workers, and advancing R&D. A well-known theoretical result in the contest literature is that greater heterogeneity decreases investments of contestants because of the "discouragement effect."...
