This discussion paper led to the article with the same title in 'Social Choice and Welfare' (2014), 43, 173-194.<P> We consider the problem of sharing water among agents located along a river. Each agent has quasi-linear preferences over river water and money, where the benefit of consuming an...</p>

We analyse river sharing games in which a set of agents located along a river shares the available water. Using coalition theory, we find that the potential benefits of water trade may not be sufficient to make all agents in the river cooperate and acknowledge property rights as a prerequisite...

The epidemiological literature suggests that virus transmission occurs only when individuals are in relatively close contact. We show that if society can control the extent to which economic agents are exposed to the virus and agents can commit to contracts, virus externalities are local, and...

This article explores subjects in optimal income taxation characterized by recent research interest, practical importance in light of concerns about inequality, potential for misunderstanding, and prospects for advancement. Throughout, the analysis highlights paths for further investigation....

"Climate change governance poses difficult challenges for contemporary political/administrative systems. These systems evolved to handle other sorts of problems and must now be adapted to handle emerging issues of climate change mitigation and adaptation. This paper examines long-term climate...

We build a novel stochastic dynamic regional integrated assessment model (IAM) of the climate and economic system including a number of important climate science elements that are missing in most IAMs. These elements are spatial heat transport from the Equator to the Poles, sea level rise,...

Climate change remains one of the major international environmental challenges facing nations. Up to now, nations have to date adopted minimal policies to slow climate change. Moreover, there has been no major improvement in emissions trends as of the latest data. The current study uses the...

Stabilizing climate change entails bringing net emissions of carbon dioxide (CO2) to zero. CO2 stays in the atmosphere for hundreds, if not thousands, of years. As long as we emit more than we capture or offset through carbon sinks (such as forests), concentrations of CO2 in the atmosphere will...
