We conduct an artefactual field experiment to study whether the individual preferences and propensity to cooperate of temporary workers differ from permanent contract workers. We find that temporary and permanent contract workers have different other-regarding preferences, but display similar...

This paper develops and tests several models of pure Nash strategies of individuals who extract from a common pool resource when they are motivated by a combination of self-interest and other motivations such as altruism, reciprocity, inequity aversion and conformism. We test whether an...

We use data from a promotion campaign of NH-Hoteles to study self-selection of participants in a gift-exchange experiment. The promotion campaign allowed guests to pay any non negative amount of money for a stay in one of 36 hotels in Belgium and the Netherlands. The data allow us to distinguish...

We analyze with an integrated assessment model of climate change the formation of interna-tional environmental agreements (IEAs) by applying the widely used concept of inter-nal & external stability and several modifications of it. We relax the assumptions of a single agreement and open...

The Kyoto summit initiated an international game of cap and trade. Unlike a national policy, the essence of this game is the self-selection of national emission targets. This differs from the standard global public-goods game because targets are met in the context of a global carbon market. This...

This paper solves the global cap-and-trade game exactly as the public-goods game is normally solved and finds a problematic outcome. Abatement of greenhouse gas emissions is a global public good, and supplying a public good is a game with strong incentives to free ride. Adding a cap-and-trade...

Two theses on the likelihood of international cooperation for achieving international optimality in transboundary pollution problems are being confronted: a pessimistic one and an optimistic one. On the one hand a "Small Stable Coalitions" (SSC) thesis ? based on the stability of coalitions...

Greenhouse gas abatement is a public good, so climate policy is a public-goods game and suffers from the free-rider incentives that make the outcome of such games notoriously uncooperative. Adopting an international agreement can change the nature of the game, reducing or exacerbating the...

We conduct an artefactual field experiment to compare the individual preferences and propensity to cooperate of three pools of subjects: Undergraduate students, temporary workers and permanent workers. We find that students are more selfish and contribute less than workers. Temporary and...

Intrinsic motivation is shaped by attitudes towards others. In spite of their potential relevance for policy design, identifying individual preference types beyond population distributions remains a challenge. We use data from a common pool resource (CPR) game in the fi eld (935 individuals, 25%...
