The lack of growth response to "Washington Consensus" policy reforms in the 1980s and 1990s led to widespread doubts about the value of such reforms. This paper updates these stylized facts by analyzing moderate to extreme levels of inflation, black market premiums, currency overvaluation,...

This paper analyzes the structural relationship between policies that distort resource allocation and long-ten growth. It first reviews briefly the Solow model in which steady-state growth depends only on exogenous technological change. Policy distortions do affect the rate of growth in the...

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...

In the new millennium, the Western aid effort towards Africa has surged due to writings by well-known economists, a celebrity mass advocacy campaign, and decisions by Western leaders to make Africa a major foreign policy priority. This survey contrasts the predominant "transformational" approach...

Previous literature suggests that leaders matter for growth in general. This paper asks which leaders matter and develops a methodology to estimate the growth contribution of individual leaders and calculate its precision. The findings show that few leaders have statistically significant...

Do superpower interventions to install and prop up political leaders in other countries subsequently result in more or less democracy, and does this effect vary depending on whether the intervening superpower is democratic or authoritarian? While democracy may be expected to decline...

We assemble a dataset on technology adoption in 1000 B.C., 0 A.D., and 1500 A.D. for the predecessors to today's nation states. We find that this very old history of technology adoption is surprisingly significant for today's national development outcomes. Although our strongest results are for...

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...

The Burnside and Dollar (2000, AER) 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...

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...
