In promotion contests or other tournament-like situations, a principal may attach some value to the highest effort expended by an agent. We show that whenever agents interact over multiple periods, awarding a head start to one of them is optimal even with completely symmetric agents. Awarding a...

Two common characteristics of populism are anti-elitism and favoring popular will over expertise. The recent successes of populists are often attributed to the common people, the majority of voters, being left behind by mainstream parties. This paper shows that the two characteristics of...

We explore how public opinion polls affect candidates' campaign spending in political competition. Generally, polls lead to (more) asymmetric behavior. Under a majority rule there always exists an equilibrium in which the initially more popular candidate invests more in the campaign and thereby...

Property rights are undoubtedly among the most important institutions for economic efficiency. Still, by looking at reality we usually see property rights only imperfectly enforced. In this paper we identify uncertainty faced by an enforcer to be sufficient to explain this observation. This...

Multiple-prize contests are important in various fields of economics ranging from rent seeking over labour economics, patent and R&D races to tendering for (governmental) projects. Hence it is crucial to understand the incentive effects of multiple prizes on effort investment. This survey...

We analyze if and how multi-prize Tullock contests can be used to guarantee efficient contributions to a public good when agents are heterogenous both with respect to the costs of production of the public good and with respect to the utility from its consumption. With two types of individuals,...
