Naturwissenschaftliche Fragen rund um den Klimawandel sind von Naturwissenschaftlern zu beantworten. Ökonomen und Wirtschaftsethiker können jedoch dazu beitragen, den Klimawandel und mögliche Gegenmaßnahmen zu bewerten. Dabei ist ein einheitlicher Preis für die Emission von Treibhausgasen...

That climate policies are costly is evident and therefore often creates major fears. But the alternative (no action) also has a cost. Mitigation costs and damages incurred depend on what the climate policies are; moreover, they are substitutes. This brings climate policies naturally in the realm...

Agricultural development is facing great challenges in meeting global food security and is expected to face even greater difficulties under climate change. The overall goal of this paper is to examine how foreign aid in particular can be used to achieve the joint objectives of development,...

The pervasive use of tax incentives is costly for the Caribbean countries, yet the benefits seem limited. Better policy coordination at the regional level is needed to help overcome the collective action problems and generate more revenue to support the much-needed infrastructure investment....

Previous research shows that collective action to avoid a catastrophic threshold, such as a climate “tipping point,” is unaffected by uncertainty about the impact of crossing the threshold but that collective action collapses if the location of the threshold is uncertain. Theory suggests...

According to the Framework Convention on Climate Change, global collective action is needed to stabilize "greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous [our emphasis] anthropogenic interference with the climate system." The Framework Convention thus...

I develop a dynamic model of private provision of public bads allowing investments in technologies. The analysis is tractable and the MPE unique. The framework is used to derive optimal incomplete contracts in a dynamic setting. While the noncooperative equilibrium is very inefficient,...

Tackling the problem of global climate change requires a high level of international cooperation. Many countries have pledged targets or actions to reduce greenhouse gas emissions in the Appendices to the Copenhagen Accord. This analysis examines the costs and effectiveness of these pledges,...

This paper seeks to give insights into how domestic voters form their preferences pro or contra compliance with IEAs and therefore how public concern for the environment and interest group activity influence national compliance behaviour. Three hypotheses are developed. First, compliance...
