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...

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...

This paper analyzes a contest in which defenders move first, have private information about the value of the objects they are trying to protect, and determine the observability of their defense efforts. The equilibrium consistent with the intuitive criterion depends on the distribution of...

We study deterrence in sequential move conflicts, modeled as a contest. We bias the model in favor of peace by assuming that under complete information deterrence is achieved and peace prevails. We show that under incomplete information about states' types (resolve) the chances of deterrence...

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...

I develop a formal model of political campaigns in which candidates choose how to distribute their resources over two different policy issues. I assume that campaigning on an issue has two simultaneous effects, both rooted in social and cognitive psychology: It increases the perceived quality of...
