This paper examines income mobility in developing countries. We start by synthesizing findings from the available evidence on relative mobility and poverty dynamics. We then describe evidence on economic mobility obtained via synthetic panels constructed from cross-section data. We echo earlier...

Global innovation and entrepreneurship has traditionally been dominated by a handful of high-income countries, especially the US. This paper investigates the international consequences of the rise of a new hub for innovation, focusing on the dramatic growth of high-potential entrepreneurship and...

This paper asks whether increasing productivity in the electricity sector can yield larger long-run GDP gains than suggested by electricity's small share of aggregate economic activity. We answer this question using a dynamic multi-sector model in which electricity is a strong complement to...

This paper analyzes the aggregate and distributional effects of publicly funded merit-based ('free') secondary schooling in the developing world. Our analysis is based on an overlapping-generations model of human capital accumulation in which households face borrowing constraints that can lead...

This paper shows that large, multi-establishment business enterprises face a high cost of middle management in poor countries and that this cost inhibits the growth of the modern sector. We provide new empirical evidence using a database covering compensation for 300,000 middle managers working...

Antipoverty policies assume that targeting poor households suffices in reaching poor individuals. We question this assumption. Our comprehensive assessment for sub-Saharan Africa reveals that undernourished women and children are spread widely across the household wealth and consumption...

This paper is a study of the dynamic relationships between two demographic variables--the infant mortality rate and the fertility rate-- using time series methodology. I believe that I have shown that infant mortality and fertility are not independent but rather are jointly determined. Also, i...

We study how extreme weather exposure impacts infant survival in the developing world. Our analysis overcomes the absence of vital registration systems in many poor countries by extracting birth histories from household surveys. Studying 53 developing countries that span five continents, we find...
