In many parts of the world, several decades of intensively applying Green Revolution technologies came at environmental costs, i.e. degraded water and soil quality as well as a loss of biodiversity. This has led to an increased interest in alternative farming systems such as organic farming,...

Cash transfers successfully alleviate poverty in many developing countries. South Africa is a case in point, implementing one of the largest unconditional cash transfer programmes internationally, and with substantial benefits to household well-being along multiple dimensions. Yet, grants...

This paper shows how the hedonic approach to vineyard site selection can be used in the adaptation of vineyard land to climate change, natural disasters or other exogenous events. The basic idea is that, if the relation between weather and grape quality is known for each grape type in existing...

Do constraints to technology adoption vary by behavioral traits? We randomize 150 villages in Bangladesh into being offered standard microcredit, loans with a grace period, the choice between those two contracts, and control. No discernible average effects are detected on the adoption of...

Like most other developing countries, China experiences huge migration outflows from rural areas. Their most striking characteristic is a high geographical and temporal mobility. Rural migrants keep going back and forth between origin villages and destination areas. In this paper, we show that...

We study the role of proximity to historical ethnic borders in determining individual land ownership in Sub-Saharan Africa. Following an instrumental variable strategy, we document that individuals have a lower likelihood of owning land near historical ethnic borders. In particular, the...

We study the role of social learning in the diffusion of cash crops in a resettled village economy in northeastern Brazil. We combine detailed geo-coded data on farming plots with dyadic data on social ties among settlers, and we leverage natural exogenous variation in network formation induced...

This paper studies the labor market consequences of ethnic politics in African democracies. We combine geo-referenced data from 15 countries, 32 parliamentary elections, 62 political parties, 243 ethnic groups, 2,200 electoral constituencies, and 400,000 individuals. We implement a regression...

This paper assesses the impact of glyphosate use in agriculture on birth outcomes of human populations in surrounding areas. Glyphosate is the most widely used herbicide in the world. Still, despite ongoing controversy, little is known about its effects on human populations at large. Our...

We explore the effect of historical ethnic borders on contemporary conflict in Africa. We document that both the intensive and extensive margins of contemporary conflict are higher close to historical ethnic borders. Exploiting variations across artificial regions within an ethnicity's...
