Agricultural productivity in Sub-Saharan Africa (SSA) lags far behind all other regions of the world. A long list of policy experiments has yielded more evidence on what fails than on what works. We analyze a randomized control trial of a rare scaled-up success story: One Acre Fund's small...

We examine whether returns to capital are higher for farmers who borrow than for those who do not, a direct implication of many credit market models. We measure the difference in returns through a two-stage loan and grant experiment. We find large positive investment responses and returns to...

Risk often inhibits on-farm investment by smallholder farmers. Recent evidence indicates that index insurance and stress tolerant seeds can separately and partially offset this risk effect. In this study, we explore whether the complementarities between these two risk management technologies can...

We revisit the long-standing empirical evidence of an inverse relationship between farm size and productivity using rich microdata from Uganda. We show that farm size is negatively related to yields (output per hectare), as commonly found in the literature, but positively related to farm...

In discussing the paradoxical violation of expected utility theory that now bears his name, Maurice Allais noted that individuals tend to "greatly value" payoffs that are certain. Allais' observation would seem to imply that people will undervalue insurance relative to the predictions of...

This paper examines whether agricultural insurance can boost investment by small scale farmers in West Africa. We conduct a randomized evaluation to analyze the impacts of index insurance for cotton farmers in Burkina Faso. We find no impact of insurance on cotton, but, consistent with...

A vast firm productivity literature finds that otherwise similar firms differ widely in their productivity and that these differences persist through time, with important implications for the broader macroeconomy. These stylized facts derive largely from studies of manufacturing firms in wealthy...

We provide a new and more complete analysis of the origins of the Dust Bowl of the 1930s, one of the most severe environmental crises in North America in the 20th Century. Severe drought and wind erosion hit the Great Plains in 1930 and lasted through 1940. There were similar droughts in the...
