"One of the recurring themes in the sustainability literature has been the legitimacy of using an economic framework to account for natural resources. This paper examines the potential for substituting between different inputs in the generation of income, where the inputs include natural...

"Theories of poverty traps stand in sharp contrast to the view that anybody can make it through hard work and thrift. However, empirical detection of poverty traps is complicated by the lack of long panels, measurement error, and attrition. This paper shows how dynamic pseudo-panel methods can...

"The authors study how the effect of trade openness on economic growth depends on complementary reforms that help a country take advantage of international competition. This issue is illustrated with a simple Harris-Todaro model where output gains after trade liberalization depend on the degree...

"The authors analyze general equilibrium relationships between trade policy and the household distribution of income, decomposing social welfare into real income level and variance components and emphasizing Gini and Atkinson indexes. They embed these inequality-adjusted social welfare functions...

"The fact that raising taxes can increase taxed labor supply through income effects is frequently used to justify much lower measures of the marginal welfare cost of taxes and greater public good provision than indicated by traditional, compensated analyses. The authors confirm that this...

"This paper first describes those features of the electricity supply industry that make a prospective market monitoring process essential to a well-functioning wholesale market. Some of these features are shared with the securities industry, although the technology of electricity production and...

"Minimum wages are generally thought to be unenforceable in developing rural economies. But there is one solution - a workfare scheme in which the government acts as the employer of last resort. Is this a cost-effective policy against poverty? Using a microeconometric model of the casual labor...

"The authors examine the empirical evidence in support of the poverty trap view of underdevelopment. They calibrate simple aggregate growth models in which poverty traps can arise due to either low saving or low technology at low levels of development. They then use these models to assess the...
