Results derived from empirical analyses on the stability of climate coalitions are usually very sensitive to the large uncertainties associated with the benefits and costs of climate policies. This paper provides the methodology of Stability Likelihood that links uncertainty about benefits and...

We analyze stability of self-enforcing climate agreements based on a data set generated by the CLIMNEG world simulation model (CWSM), version 1.2. We consider two new aspects which appear important in actual treaty-making. First, we consider a sequential coalition formation process where players...

International climate negotiations take place in a setting where uncertainties regarding the impacts of climate change are very large. In this paper, we examine the influence of increasing the probability and impact of large climate change damages, also known as the 'fat tail', on the formation...

Two phenomena are increasingly reshaping the world economy. One is the growing and well-documented importance of climate transition policies that differ across countries. The other is the stark rise of geoeconomic fragmentation (GEF) concerns. While differences in climate transition policies are...

This paper analyzes the stability of international environmental agreements in a dynamic game when the generation of both renewables and fossil fuel based energy requires specialized capital stocks or technologies, respectively. Two contract types are considered. At an incomplete (a complete)...

Im Jahr 2021 vereinbarte die G7 mit Südafrika eine Partner schaft für eine gerechte Energiewende (JETP). Dieses - neue - Instrument der internationalen Zusammenarbeit soll Schwellen und Entwicklungsländer bei einer sozialgerechten Energiewende und beim Kohleausstieg unterstützen. Mit diesem...

In 2021, the G7 and South Africa agreed upon the Just Energy Transition Partnership (JETP). This new instrument in interna- tional cooperation should support emerging and developing economies in a just energy transition and in phasing out coal. It is intended to facilitate equal partnerships...

This paper investigates the implications of implementing the Just Energy Transition Partnership (JETP) in South Africa by exploring the factors that are at work when donors and recipients interact with each other. It analyses the JETP using global cooperation theories on climate change and...

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,...

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,...
