National economic policies’ effects on growth were over-emphasized in the early literature on endogenous economic growth. Most of the early theoretical models of the new growth literature (and even their new neoclassical counterparts) predicted large policy effects, which was followed by...

After excluding countries with high-inflation crises - periods when annual inflation is above 40 percent - the data reveal no evidence of a consistent relationship between growth and inflation, at any frequency. But growth does tend to fall sharply during discrete crises of high inflation and to...

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,...

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...

The authorexamines a range of cross-sectional variation in performance and policies for evidence on what distinguishes successes from failures. At about 6 percent, the growth rate of the Four Tigers - Hong Kong, the Republic of Korea, Singapore, and Taiwan (China) - are among the largest...

Using a newly assembled dataset spanning from 1820 to 1998, we study the relationship between the occurrence and magnitude of episodes of mass killing and the levels of development and democracy across countries and over time. Mass killings appear to be more likely at intermediate levels of...

The Schelling model of a "tipping point" in racial segregation, in which whites flee a neighborhood once a threshold of nonwhites is reached, is a canonical model of strategic interdependence. The idea of "tipping" explaining segregation is widely accepted in the academic literature and popular...

Artificial states are those in which political borders do not coincide with a division of nationalities desired by the people on the ground. We propose and compute for all countries in the world two new measures how artificial states are. One is based on measuring how borders split ethnic groups...
