I argue that increased consumption of vegetable seed oils high in omega-6 polyunsaturated fats has driven obesity in the United States, a link overlooked in the economics literature. Obesity rates have closely tracked the level of seed oils in the food supply since 1960, while diverging from...

We decompose the relationship between food aid and conflict into the channels through which food aid can affect conflict. We address questions of methodological choice and estimation techniques for empirical studies. Our review of the empirical evidence on the effect of food aid on conflict...

Long-term follow-up of early childhood health interventions is important for human capital accumulation. We provide experimental evidence on child health and human capital outcomes from the longer-term follow-up of a school-based nutrition intervention in India. Using panel data, we examine the...

This paper examines the impact of COVID-19 vaccination on food insecurity in the United States, using data from the Household Pulse Survey. Our primary research design exploits variation in vaccine eligibility across states over time as an instrumental variable to address the endogeneity of...

Food insecurity is one of the most, if not the most, significant, nutrition-related public health issue confronted in the US. Unfortunately, we know very little about the determinants of food security except that it is not synonymous with poverty. Many households above the poverty line are food...

This paper evaluates causal impacts of a large-scale agricultural extension program for smallholder women farmers on food security in Uganda through a regression discontinuity design that exploits an arbitrary distance-to-branch threshold for village program eligibility. We find eligible farmers...

Using a four-round panel data set from the first phase of the Challenging the Frontiers of Poverty Reduction – Targeting the Ultra Poor (CFPR – TUP) programme of BRAC, we investigate whether a one-off transfer of livestock assets improves well-being of the very poor women in Bangladesh....

The dissolution of the Soviet Union and 1992-96 Tajik civil war resulted in huge human and economic losses. Nevertheless, contemporary data suggest the persistence of investments in human capital in the region most affected by famine and least favoured since the cessation of hostilities,...

In low-income settings, women are vulnerable to the psychological distress caused by the social and economic impact of large-scale shocks (e.g., pandemics, natural disasters, political). This paper evaluates a randomized over-the-phone counseling intervention aimed at mitigating the mental...

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...
