We survey the empirical literature on floating nominal exchange rates over the past decade. Exchange rates are difficult to forecast at short- to medium-term horizons. There is a bit of explanatory power to monetary models such as the Dornbusch 'overshooting' theory, in the form of reaction to...

In pursuit of more aggressive environmental goals, we now advance the dates at which some countries are asked to begin cutting below BAU, within our framework. We also tinker with the values for the parameters in the formulas. The resulting target paths for emissions are run through the WITCH...

Fears that globalization necessarily hurts the environment are not well-founded. A survey reveals little statistical evidence, on average across countries, that openness to international trade undermines national attempts at environmental regulation through a race to the bottom' effect. If...

We explore a framework that could be used to assign quantitative allocations of emissions of greenhouse gases (GHGs), across countries, one budget period at a time. Under the two-part plan: (i) China, India, and other developing countries accept targets at Business as Usual (BAU) in the coming...
