Recent climate change negotiations have emphasised the need for developing countries to take the lead by undertaking economy-wide absolute emission reduction targets but also the obligation of developed countries to provide financial resources to assist them in their mitigation efforts. This...

This paper explores the role of multilateral transfers in achieving strict Pareto improvements in welfare, focusing on identifying conditions under which their use is warranted when carbon prices differ internationally and there are impediments to international trade. Using a general equilibrium...

International Environmental Agreements (IEAs) that address global environmental problems with cross-border externalities (i.e., climate change) suffer from severe free-riding problems resulting in limited national participation. Gains and losses in international trade are concerning when...

This paper studies the interplay between climate, health, and the economy in a stylized world with four heterogeneous regions, labeled ‘West’ (cold and rich), ‘China’ (cold and poor), ‘India’ (warm and poor), and ‘Africa’ (warm and very poor). We introduce health impacts into a...

A Bayesian typically uses data and a prior to produce a posterior. In practice, the data and the posterior are often observed but not the prior. We shall follow the opposite route, using data and the posterior information to reveal the prior. We then apply this theory to (equilibrium) climate...

In the context of extreme climate change, we ask how to conduct expected utility analysis in the presence of catastrophic risks. Economists typically model decision making under risk and uncertainty by expected utility with constant relative risk aversion (power utility); statisticians typically...
