Since independence a quiet revolution has taken place in maize production in the Sahel with Mali increasing production more than ten-fold and yields going up ~2% a year. This research work uses farm level panel data from southern Mali's maize growing regions to demonstrate this success in...

This paper tests financial accelerator models. Using a novel dataset on agricultural production, we examine how exogenous productivity shocks arising from variation in temperature are propagated into the future. We find that past weather shocks have persistent effects on land values and...

This paper explores the idea that competitive seed systems may underserve farmers in small, agro-ecological niches, leaving those farmers less productive and poorer than they need be. We develop a theoretical model of the confluence of demand and supply factors that can result in such an...

James Michael Curley, a four-time mayor of Boston, used wasteful redistribution to his poor Irish constituents and incendiary rhetoric to encourage richer citizens to emigrate from Boston, thereby shaping the electorate in his favor. Boston as a consequence stagnated, but Curley kept winning...

We examine the productivity of informal firms (those that are not registered with the government) in 24 African countries using field work and World Bank firm level data. We find that productivity jumps sharply if we compare small formal firms to informal firms, and rises rapidly with the size...

Lesotho and other least developed African countries responded impressively to the preferences they were granted under the African Growth and Opportunities Act with a rapid increase in their clothing exports to the US. But this performance has not been accompanied by some of the more dynamic...
