We provide new measures of ethnic, linguistic and religious fractionalization for about 190 countries. These measures are more comprehensive than those previously used in the economics literature and we compare our new variables with those previously used. We also revisit the question of the...

The negative growth-inflation association in the existing literature is usually interpreted as a long-run relationship. But the existing literature on inflation and growth has a puzzling anomaly: there is little evidence of a relationship with low-frequency (30-year) data, but inflation and...

The widely publicized finding that "aid promotes growth in a good policy environment" is not robust to the inclusion of new data or alternative definitions of "aid," "policy" or "growth." The idea that "aid buys growth" is on shaky ground theoretically and empirically. It doesn't help that aid...

The Burnside and Dollar (2000) finding that aid raises growth in a good policy environment has had an important influence on policy and academic debates. We conduct a data gathering exercise that updates their data from 1970-93 to 1970-97, as well as filling in missing data for the original...

Explaining cross-country differences in growth rates requires not only an understanding of the link between growth and public policies, but also an understanding of why countries choose different public policies. This paper shows that ethnic diversity helps explain cross-country differences in...

The classic narrative of economic development - poor countries are caught in poverty traps, out of which they need a Big Push involving increased aid and investment, leading to a takeoff in per capita income - has been very influential in development economics since the 1950s. This was the...

Analysis of adjustment loans often overlooks their repetition to the same country. Repetition changes the nature of the selection problem. None of the top 20 recipients of repeated adjustment lending over 1980-99 were able to achieve reasonable growth and contain all policy distortions. About...

The international effort to meet the Millennium Development Goals by 2015 has given fresh prominence to the idea of poverty traps, a notion that was widely current in the 1950s. This idea, most actively promoted by economist Jeffrey Sachs, director of Columbia University's Earth Institute and...

Using a newly assembled dataset spanning from 1820 to 1998, we study the relationship between the occurrence and cruelty of episodes of mass killing and the levels of development and democracy across countries and over time. We find that massacres are more likely at intermediate levels of income...
