Economic theory suggests that liberalization of trade between countries with differing levels of environmental protection could lead pollution-intensive industry to concentrate in the nations where regulations are lax. This effect, often referred to as the "pollution haven" hypothesis, is much...

The North American Free Trade Agreement (NAFTA) had a profound impact on corn trade between the United States and Mexico. Negotiated tariff reductions and the Mexican government’s decision not to charge some tariffs to which it was entitled resulted in a doubling of US corn exports to Mexico....

The European Union is moving toward adoption of its new Registration, Evaluation and Authorization of Chemicals (REACH) policy, an innovative system of chemicals regulation that will provide crucial information on the safety profile of chemicals used in industry. Chemicals produced elsewhere,...

Economic models of climate change often take the problem seriously, but paradoxically conclude that the optimal policy is to do almost nothing about it. We explore this paradox as seen in the widely used DICE model. Three aspects of that model, involving the discount rate, the assumed benefits...

Recent research paints an ominous picture of climate impacts on agriculture, in contrast to the relative optimism of research from the 1990s. Continued use of the earlier research findings, in economic models and policy analyses, contributes to an unwarranted complacency about the urgency of...

Computable general equilibrium (CGE) models of world trade, often presented as demonstrating the benefits of trade liberalization, now make much more modest forecasts than they did just a few years ago. The estimated benefits are not only small in the aggregate, but also skewed toward developed...

A growing body of scientific literature implicates toxic exposures in childhood illnesses and developmental disorders. When these illnesses and disabilities result from environmental factors under human control, they can and should be prevented. This report documents monetary costs associated...
