Markov perfection has become the usual solution concept to determine the non-cooperative equilibrium in a dynamic game. However, Markov perfection is a stronger solution concept than subgame perfection: Markov perfection rules out any cooperation in a repeated prisoners' dilemma game because the...

Development assistance has been criticized for a lack of coordination between aid donors. This paper argues that competition for export markets and political support prevents donor countries from closer coordination of aid activities. To test these hypotheses, we perform logit and fractional...

Recent research has shown that agreements centered on the adoption of breakthrough technologies can break the deadlock in international climate negotiations if the mitigation technology exhibits a network externality that transforms full cooperation into a self-enforcing outcome. This paper...

CCS (carbon dioxide capture and storage) is an issue which has received increasing attention in the debate on climate change over the last years because of its relative technical simplicity and a large expected potential in reducing carbon dioxide emissions. The coexistence of both strong...

This paper provides insights into the apparent seesaw between the generation of theoretical versus empirical economics research over time. A dynamic model considers the incentives of researchers to focus on empirical versus theoretical papers. It yields the main characteristics of the...

We use the new version of the GTAP-W model to analyze the economy-wide impacts of enhanced irrigation efficiency. The new production structure of the model, which introduces a differentiation between rainfed and irrigated crops, allows a better understanding of the use of water resources in...

The paper is concerned with effects of lobbying activities by political pressure groups that wish to affect environmental legislation. Two interest groups are considered, environmentalists on the one hand and a polluters' lobby on the other. These two groups can influence the environmental...
