How does a citizen's decision to participate in political activism depend on the participation of others? We conduct a nation-wide natural field experiment in collaboration with a major European party during a recent national election. In a seemingly unrelated survey, we randomly provide...

How does a citizen's decision to participate in political activism depend on the participation of others? We examine this core question of collective action in a nation-wide natural field experiment in collaboration with a major European party during a recent national election. In a seemingly...

We study theoretically and experimentally a two-person partnership game whereby agents only see the uncertain outcome of their joint effort but not how much the other agent contributed to it. The model combines problems of free-riding present in public good production and in teams with imperfect...

In this paper, we extend the Fehr and Schmidt model of inequality aversion to a situation where the players differ with respect to their benefits and costs from contributions to a non-linear public good. A necessary condition for contributing to the public good is that the players' benefit...

In this paper we consider the effect of ambiguity on the private provision of public goods. Equilibrium is shown to exist and be unique. We examine how provision of the public good changes as the size of the population increases. We show that when there is uncertainty there may be less...

Lying to participants offers an experimenter the enticing prospect ofmaking others' behaviour a controlled variable,but is eschewed by experimental economists because it may pollute thepool of subjects. This paper proposes andimplements a new experimental design, the Conditional...

We compare male and female behavior in Japan and Canada in the context of a threshold public goods game with both a strong free-riding equilibrium and many socially efficient threshold equilibria. Although higher rewards produce higher contributions, neither culture nor gender has any...
