This paper reviews the empirical evidence on the existence of poverty traps, understood as self-reinforcing mechanisms through which poor individuals or countries remain poor. Poverty traps have captured the interest of many development policy makers, because poverty traps provide a...

Social welfare functions that assign weights to individuals based on their income levels can be used to document the relative importance of growth and inequality changes for changes in social welfare. In a large panel of industrial and developing countries over the past 40 years, most of the...

The Egyptian pound depreciated sharply between 2000 and 2005, declining by 26 percent in nominal trade-weighted terms. The author investigates the effect of the large depreciation on household welfare operating through exchange rate-induced changes in consumer prices. He estimates exchange rate...

Business cycles are less volatile in rich countries than in poor ones. They are also more synchronized with the world cycle. The authors develop two alternative but noncompeting explanations for those facts. Both explanations proceed from the observation that the law of comparative advantage...

A look at the data reveals that in OECD countries, economic fluctuations exhibit a high degree of synchronization. In 1965-90, cross-country contemporaneous GDP growth correlations averaged 45 percent. This suggests that a central element of any theory of economic fluctuations should be an...

Drawing on evidence from a large sample of speculative attacks in industrial and developing countries, the author argues that high interest rates do not defend currencies against speculative attacks. In fact, there is a striking lack of any systematic association between interest rates and the...

The evidence from individual cases and from cross-country analysis supports the view that globalization leads to faster growth and poverty reduction in poor countries. To determine the effect of globalization on growth, poverty, and inequality, the authors first identify a group of developing...

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...

The validity of instrumental variables (IV) regression models depends crucially on fundamentally untestable exclusion restrictions. Typically exclusion restrictions are assumed to hold exactly in the relevant population, yet in many empirical applications there are reasonable prior grounds to...

Many highly-disaggregated cross-country indicators of institutional quality and the business environment have been developed in recent years. The promise of these indicators is that they can be used to identify specific reform priorities that policymakers and aid donors can target in their...
