When a deficit occurs in the funding of collective goods, it is usually covered by raising the amount of taxes or by rationing the supply of the goods. This article compares the efficiency of these institutions. We report the results of a 2x2 experiment based on a game in the first stage of...

We experimentally test the ability of subjects to identify repeated-game strategies from prisoner's dilemma choice data. In the experiments, subjects use a finite state grammar to build models to fit game histories. The histories are designed to distinguish between strategies with empirical and...

Theories of voter turnout assume that an active voter receives a warm glow from doing a good deed to like-minded compatriots. What tells him that he is doing them a good deed by voting for this or that candidate or policy? Their own votes are naturally available feedback. We propose a dynamic...

In a public-good experiment with heterogeneous endowments, we investigate if and how the contribution level as well as the previously observed fair-share rule of equal contributions relative to one's endowment (Hofmeyr et al., 2007; Keser et al., 2014) may be influenced by minimum-contribution...

Subjects submitted strategies for playing a public good game. The strategies interacted with each other in a computer simulation. They could be revised and resubmitted for a second and a third simulation round. The strategies' average contribution to the public good increased from one simulation...

We develop a theoretical model in which each individual is, in some ultimate sense, motivated by purely egoistic satisfaction derived from the goods accruing to him, but there is an implicit social contract such that each performs duties for the others in a way that enhances the satisfaction of...

We evaluate biodiversity in a real options framework, when the resources in use are substitutable. We examine optimal conservation decisions given that a biodiversity loss is irreversible and that future use values are uncertain. While species substitutability is generally believed to reduce the...

We derive corrective tax rules when firms are oligopolists whose production processes generate emissions that add to a stock of pollution that accumulates over time. In our model, firms play dynamic Cournot games among themselves, and the government designs a tax rule that corrects for both the...

We show that, in a model with substitutability between capital and resources, the path of sustainable development may be non-smooth, and may exhibit the overshooting property: starting from low levels of capital and resources, the economy may accumulate capital beyond its steady-state level,...

In public goods experiments where subjects may change groups, we observe a continual flight of the more cooperative subjects away from the less cooperative ones. The less cooperative subjects attempt to enter cooperative groups in order to free-ride on their contributions. Lorsque les sujets...
