Reflecting the emphasis of recent work in the field of trade and the environment, this review focuses on empirical issues, primarily econometric estimates of the pollution haven effect and simulation-based calculations of carbon leakage. A brief discussion of the theory explains why intuition...

Low probability catastrophic climate change can have a significant influence on policy under hyperbolic discounting. We compare the set of Markov Perfect Equilibria (MPE) to the optimal policy under time-consistent commitment. For some initial levels of risk there are multiple MPE; these may...

“Prices versus quantities” (Weitzman 1974), a hugely influential paper, is widely cited (and taught) in current debates about the best policy to reduce greenhouse gas emissions. The paper’s criterion for ranking policies suggests that technological uncertainty favors taxes over cap and...

We analyze a dynamic model of international environmental agreements (IEAs) where countries cannot make long-term commitments or use sanctions or rewards to induce cooperation. Countries can communicate with each other to build endogenous beliefs about the random consequences of (re)opening...
