Regional trade in South America since independence has long been much smaller than would be expected if geography were the only constraint on trade. Several potential explanations exist: low technological and demand complementarities; low productivity; high natural and policy barriers to trade....

Forestation is viewed as an important means of removing CO₂ from the atmosphere and thereby reducing net CO₂ emissions. But how much CO₂ can be removed, and at what cost? Focusing on forested and forestable areas in South America, and using spatially disaggregated data, we estimate a...

We asked 97 cigarette smokers to make a series of 12 binary choices between experimental cigarette packages with varying warnings and background colors. Each smoker had to decide which of the two packages contained cigarettes less risky for his health. We tested whether the smokers, confronted...

Large devaluations are generally associated with large declines in real exchange rates. We develop a model which embodies two complementary forces that account for the large declines in the real exchange rate that occur in the aftermath of large devaluations. The first force is sticky...

This paper uses a unified analytical framework to assess, both qualitatively and quantitatively, the relevance of the different hypotheses that have been proposed to explain the real effects of exchange rate-based stabilizations. The four major hypotheses analyzed are: (i) the supply-side...
