This paper experimentally explores how the enforcement of cooperative behavior in a social dilemma is facilitated through institutional as well as emotional mechanisms. Recent studies emphasize the importance of negatively valued emotions, such as anger, which motivate individuals to punish free...

This paper develops a model of conflict resolution over scarce water in a trans-boundary river. In our model, we consider countries that are located along a river and made a military investment. Given these investments and their location along the river, they sequentially bargain over the...

We augment the standard cartel formation game from non-cooperative coalition theory, often applied in the context of international environmental agreements on climate change, with the possibility that singletons support coalition formation without becoming coalition members themselves. Rather,...

In this paper we consider the problem of sharing water from a river among a group of agents (countries, cities, firms) located along the river. The benefit of each agent depends on the amount of water consumed by the agent. An allocation of the water among the agents is efficient when it...

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...

We characterise the entire set of symmetric stationary Markov-perfect Nash equilibria (MPE) in a differential game of public good investment, using the canonical problem of climate change as an example. We provide a sufficient and necessary condition for MPE and show how the entire set of MPE is...

Incentives based on esteem, honor and shame are increasingly popular and easy to use due to modern surveillance techniques. However, the use of shaming is controversial: critics argue that delegating punishment to a crowd can lead to mob justice and a loss of control over the size of the...
