Growth is pro-poor if the poverty measure of interest falls. According to this definition there are three potential sources of pro-poor growth: (1) a high rate of growth of average incomes; (2) a high sensitivity of poverty to growth in average incomes; and (3) a poverty-reducing pattern of...

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...

Small states have attracted a good deal of research. The authors test whether micro-states are any different from other states in income, growth, and volatility. They find that, controlling for location, smaller states are actually richer than other states in per capita GDP. This income...

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...

Capital flows to developing countries are small and take mostly the form of loans rather than direct foreign investment. We build a simple model of North-South capital flows that highlights the interplay between diminishing returns, production risk and sovereign risk. This model generates a set...

This paper examines the determinants of"debt distress,"which they define as periods in which countries resort to exceptional finance in any of three forms: (1) significant arrears on external debt, (2) Paris Club rescheduling, and (3) nonconcessional International Monetary Fund lending. Using...

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...

The authors reexamine a classic question in international economics: What is the current account response to a transitory income shock such as a temporary improvement in the terms of trade, a transfer from abroad, or unusually high production? To answer this question, they construct a world...

The authors consider two alternative methods of forecasting real per capita GDP at various horizons: 1) univariate time series models estimated country by country; and 2) cross-country growth regressions. They evaluate the out-of-sample forecasting performance of both approaches for a large...

The authors use data from more than 6,000 World Bank projects evaluated between 1983 and 2009 to investigate macro and micro correlates of project outcomes. They find that country-level"macro"measures of the quality of policies and institutions are very strongly correlated with project outcomes,...
