Poverty reduction is now, and quite properly should remain, the primary objective of the World Bank. But, when the World Bank dreams of a world free of poverty-what should it be dreaming? I argue in this essay that the dream should be a bold one, that treats citizens of all nations equally in...

The welfare of the poor turns in large measure not only on technocratic development quot;policiesquot;, but the effective delivery of key public services, core elements of which require thousands of face-to-face discretionary transactions (quot;practicesquot;) by service providers. The...

It is easy to learn the average income of a resident of El Salvador or Albania. But there is no systematic source of information on the average income of a Salvadoran or Albanian. We create a first estimate a new statistic: income per natural - the mean annual income of persons born in a given...

For decades, migration economics has stressed the effects of migration restrictions on income distribution in the host country.

Decades of programmatic experimentation by development NGOs combined with the latest empirical techniques for estimating program impact have shown that a well-designed, well-implemented, multi-faceted intervention can in fact have an apparently sustained impact on the incomes of the poor...

In this paper we examine how policymakers and practitioners should interpret the impact evaluation literature when presented with conflicting experimental and non-experimental estimates of the same intervention across varying contexts. We show three things. First, as is well known,...
