This paper considers procurement auctions with costly bidding when the auctioneer is unable to commit himself to restrict the number of bidders. The auctioneer can, however, offer a financial reward to be paid to every short-listed bidders as an indirect commitment device. Rewards for...

Several empirical findings have challenged the traditional view on the trade-off between risk and incentives. By combining risk aversion and limited liability in a standard principal-agent model the empirical puzzle on the positive relationship between risk and incentives can be explained....

Individuals who compete in a contest-like situation (for example, in sports, in promotion tournaments, or in an appointment contest) may have an incentive to illegally utilize resources in order to improve their relative positions. We analyze such doping within a tournament game between two...

We analyze the optimal design of rank-order tournaments with heterogeneous workers. Iftournament prizes do not differ between the workers(uniform prizes), as in the previous tournament literature, the outcome will be ineffcient. In the case of limited liability, the employer may benefit from...

Several empirical studies have challenged tournament theory by pointing out that (1) there is considerable pay variation within hierarchy levels, (2) promotion premiums only in part explain hierarchical wage differences and (3) external recruitment is observable on nearly any hierarchy level. We...

Mergers that substantially lessen competition are challenged by antitrust authorities. Instead of blocking anticompetitive transitions straight away, authorities might choose to negotiate with the merging parties and allow the transactions to proceed with modifications that restore or preserve...

This paper applies a novel methodology to a unique dataset of large concentrations during the period 1990-2002 to assess merger control’s effectiveness. By using data gathered from several sources and employing different evaluation techniques, we analyze the economic effects of the...

Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004The existing literature on the comparison of tournaments and piece rates as alternative incentive schemes has focused on the case of unlimited liability. However, in practice real workers’ wealth is typically...

In this paper, we analyze a principal's optimal feedback policy in tournaments. We close a gap in the literature by assuming the principal to be unable to commit to a certain policy at the beginning of the tournament. Our analysis shows that in equilibrium the principal reveals in-termediate...
