The authors systematically document remarkably high degrees of concentration in manufacturing exports for a sample of 151 countries over a range of 3,000 products. For every country manufacturing exports are dominated by a few"big hits"which account for most of the export value and where...

There is widespread consensus among economists that high inflation is often caused by the government's need to raise seignorage to finance high budget deficits. Depending on the shape of the money demand function, steady-state seignorage may follow a Laffer curve, where seignorage first rises...

Analysis of decade-long growth rates in all countries shows a striking regularity: episodes of rapid growth are limited largely to a middle range of initial income; neither very poor nor very rich countries experienced rapid growth. Episodes of negative growth are limited to low and middle-income...

The author presents a simple endogenous growth model (with two types of capital) that shows the sizable long-run effects on growth of distortionary policies. The model applies to many different types of distortions of relative prices common in developing countries - for example, price controls,...

After years of poor economic performance, many Latin American countries undertook ambitious programs of macroeconomic stabilization andstructural reform in recent years. This change in policy created high expectations for the region, and some observers have questioned whether actual growth...

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...

Africa's economic history since 1960 fits the classical definition of tragedy: potential unfulfilled with disastrous consequences. The authors use one mehthodology - cross-country regressions - to account for sub-Saharan Africa's growth performance over the past 30 years and to suggest policies...

How did highly indebted poor countries become highly indebted after two decades of debt relief efforts? A set of theoretical models predict that countries with unchanged long-run savings preferences will respond to debt relief with a mixture of asset decumulation and new borrowing. A model also...

Fiscal deficits have been at the forefront of macroeconomic adjustment in the 1980s, both in developing and developed countries. Fiscal deficits were blamed in good part for the assortment of ills that beset developing countries in the 1980s: over-indebtedness leading to the debt crisis...

Modern political economy stresses"society's polarization"as a determinant of development outcomes. Among the most common dorms of social conflict are class polarization, and ethnic polarization. A middle class consensus is defined as a high share of income for the middle class and a low degree...
