We report and analyze the results of a series of classroom experiments on the voluntary provision of public goods. Using fixed effect panel regression models we find that cooperation significantly increases when participants are forced to guess the degree of overall cooperation. We also find...

Many, if not most, personalistic dictatorships end up with a disastrous decision such as Hitler's attack on the Soviet Union, Hirohito's government launching a war against the United States, or Putin's invasion of Ukraine in February 2022. Even if the decision is not ultimately fatal for the...

Der Umgang mit staatlich verantworteten Menschenrechtsverletzungen in Autokratien stellt die Weltgemeinschaft noch immer vor große Herausforderungen. Weder über militärische (humanitäre) Interventionen, Wirtschaftssanktionen noch über die Variation bei den Entwicklungshilfeleistungen konnte...

Traditional unobserved component models assume that the trend, cycle and seasonal components of an individual time series evolve separately over time. Although this assumption has been relaxed in recent papers that focus on trend-cycle interactions, it remains at the core of all seasonal...

In games with strategic complementarities, public information about the state of the world has a larger impact on equilibrium actions than private information of the same precision, because the former is more informative about the likely behavior of others. This may lead to welfare-reducing...

In many economic contexts, an elusive variable of interest is the agent's expectation about relevant events, e.g. about other agents' behavior. Recent experimental studies as well as surveys have asked participants to state their beliefs explicitly, but little is known about the causal relation...

We study two person-betting games with inconsistent commonly know beliefs, using an experimental approach. In our experimental games, participants bet against one another, each bettor choosing one of two possible outcomes, and payoff odds are know at the time bets are placed. Bettors’ beliefs...
