Market completeness has important implications for household behavior. I firmly reject complete markets for smallholders but am unable to do so for non-smallholders. This leads to important differences in production behavior: smallholders reallocate labor across activities less in response to...

The last decade has seen a resurgence of parastatal crop marketing institutions in sub-Saharan Africa, many of which cite improving food security and incomes as key goals. However, there is limited empirical evidence on the welfare effects of these programs. This article considers one such...

This paper provides evidence of the long-run effects of a permanent increase in agricultural productivity on conflict. We construct a newly digitized and geo-referenced dataset of battles in Europe, the Near East and North Africa covering the period between 1400 and 1900 CE. For variation in...

Climate change is predicted to affect global rainfall patterns, but there is mixed evidence with regard to the effect of rainfall on civil conflict. Even among researchers who argue that rainfall reduces civil conflict, there is disagreement as to the underlying mechanism. Using data from the...

I document negative externalities of air pollution in the Indian agricultural sector. Using variation in pollution induced by changes in wind across years, I show that higher levels of pollution lead to decreased agricultural productivity, with large changes in productivity being common. The...

This paper argues that climate change poses two distinct, if related, sets of challenges for poor rural households: challenges related to the increasing frequency and severity of weather shocks and challenges related to long-term shifts in temperature, rainfall patterns, water availability, and...

Many development programs are based on short-term interventions, either because of external funding constraints or because it is assumed that impacts persist post program termination ("sustainability"). Using a novel randomized phase-out research method, we provide experimental tests of the...

Many development programs are short-term interventions, either because of external funding constraints or an assumption of impact sustainability. Using a novel randomized phaseout research method, we provide experimental tests of phaseout effects of an extension program designed for women...

African agriculture's importance for sustainable development is well appreciated. Indeed, recent years have seen a thorough reappraisal of the sector. What are less well understood, however, are the drivers that reallocate scarce human and physical resources across occupations and space, and...

We are the first to provide a comparative empirical analysis of non-farm entrepreneurship in rural Africa, using the World Bank's unique LSMSISA dataset. This dataset covers six countries over the period 2005 to 2012. We find that rural enterprises tend to be small, informal household...
