Field research attempted to measure the risky environments, the information structures, the institutions, and the risk-response mechanisms of ten villages in northern Thailand. Various key features are then modeled in an abstract but realistic way, either with a full-information risk-sharing model or an information-constrained version of the same model. Observations from some of the villages seem consistent with one or the other of these models, but in many of the villages one is left with risk-response variations across households which suggest that Pareto improvements are possible.

This paper examines how national income and trading opportunities interact to determine the level and incidence of world pollution. We find that (i) free trade raises world pollution if incomes differ substantially across countries; (ii) if trade equalizes factor prices, human-capital-abundant countries lose from trade, while human-capital-scarce countries gain; (iii) international trade in pollution permits can lower world pollution even when governments' supply of permits is unrestricted; (iv) international income transfers may not affect world pollution or welfare; and (v) attempts to manipulate the terms of trade with pollution policy leave world pollution unaffected.

In this paper, we consider two measures of the relative effectiveness of public and Catholic schools: finishing high school and starting college. These measures are potentially more important indicators of school quality than standardized test scores in light of the economic consequences of obtaining more education. Single-equation estimates suggest that for the typical student, attending a Catholic high school raises the probability of finishing high school or entering a four-year college by thirteen percentage points. In bivariate probit models we find almost no evidence that our single-equation estimates are subject to selection bias.
