Introducing a threshold in the sense of a minimal project size transforms a public goods game with an inefficient equilibrium into a coordination game with a set of Pareto-superior equilibria. Thresholds may therefore improve efficiency in the voluntary provision of public goods. In our one-shot...

Reciprocity can be a powerful motivation for human behaviour. Scholars argue that it is relevant in the context of private provision of public goods. We examine whether reciprocity can resolve the associated coordination problem. The interaction of reciprocity with cost-sharing is critical....

Capital tax competition is known to result in inefficiently low tax rates and an undersupply of public goods. The provision of public goods and with it the welfare of all countries can be enhanced via tax coordination. Based on the standard Zodrow-Mieszkowski-Wilson tax-competition model this...

Field evidence suggests that agents belonging to the same group tend to behave similarly, i.e., behavior exhibits social interaction effects. Testing for such effects raises severe identification problems. We conduct an experiment that avoids these problems. The main design feature is that each...

Games like EverQuest and Dark Age of Camelot occasionally produce natural experiments in social science: situations that, through no intent of the designer, offer controlled variations on a phenomenon of theoretical interest. This paper examines two examples, both of which involve the theory of...

This paper assumes that groups of consumers in network markets can coordinate their choices when it is in their best interest to do so, and when coordination does not require communication. It is shown that multiple asymmetric networks can coexist in equilibrium if consumers have heterogeneous...

This paper explores three aspects of strategic uncertainty: its relation to risk, predictability of behavior and subjective beliefs of players. In a laboratory experiment we measure subjects ̕certainty equivalents for three coordination games and one lottery. Behavior in coordination games is...

In this paper we model the interaction between leaders, their followers and crowd followers in a coordination game with local interaction. The steady states of a dynamic best-response process can feature a coexistence of Pareto dominant and risk dominant actions in the population. The existence...

We propose and experimentally test a theory of strategic behavior in which players are cognitively imprecise and perceive a fundamental parameter with noise. We focus on 2 x 2 coordination games, which generate multiple equilibria when perception is precise. When adding a small amount of...

What are the incentives for governments to coordinate their policies internationally when there is model disagreement and uncertainty? We build a model where countries disagree on policy targets and how policies affect the economies, and show that uncertainty not only determines the type of...
