We show that U.S. withdrawal from the Kyoto Protocol is straightforward under political economy considerations. The reason is that U.S. compliance costs exceed low willingness to pay for dealing with global warming in the U.S. The withdrawal had a crucial impact on the concretion of the Protocol...

Klimaschutz stellt aus Sicht der ökonomischen Theorie ein rein öffentliches Gut dar. Internationale Kooperation zum Zweck der Milderung oder Verhinderung der globalen Erwärmung ist daher mit den bekannten fatalen Anreizproblemen behaftet: Auf der Basis freiwilliger, dezentraler Entscheidungen...

In this paper, we analyse if individual inequality aversion measured with simple experimental games depends on whether the monetary endowment in these games is either a windfall gain (“house money”) or a reward for a certain effort-related performance. Moreover, we analyse whether the way of...

In this paper, we investigate the real demand for climate protection. For this purpose we conducted a framed field experiment with a sample of the residential population in Mannheim, Germany. Participants were endowed with € 40 and given the opportunity to contribute to climate protection by...

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...

Based on unique data from a world-wide survey of agents involved in international climate policy, this paper empirically analyzes the importance of equity in this field. We find that equity issues are considered highly important in international climate negotiations and that the polluter-pays...

We present a simple two-steps procedure for a within-subject test of the inequity aversion model of Fehr and Schmidt (1999). In the first step, subjects played modified ultimatum and dictator games and were classified according to their preferences. In the second step, subjects with specific...

This paper investigates in how far equity preferences may matter for climate negotiations. For this purposes we conducted a simple experiment with people who have been involved in international climate policy. The experiment, which was run via the Internet, consisted of two simple non-strategic...

This paper demonstrates that cooperation in international environmental negotiations can be explained by preferences for equity. Within a N-country prisoner's dilemma in which agents can either cooperate or defect, in addition to the standard non-cooperative equilibrium, cooperation of a large...
