The discovery of transgenic products in maize (Zea mays) landraces planted by small-scale Mexican farmers (Quist and Chapela, 2001, 2002; Christou, 2002; Editorial Note, 2002) raised questions about how the commercial introduction of transgenic maize varieties might affect the traditional agricultural systems of small-scale farmers. A key concern is whether their introduction will have a delete...

Recent studies investigating the relationship between crop genetic diversity and human cultural diversity patterns showed that seed exchanges are embedded in farmers' social organization. However, our understanding of the social processes involved remains limited. We investigated how farmers' membership in three major social groups interacts in shaping sorghum seed exchange networks in a cultur...

We develop and estimate a discrete-choice model of differentiated products for the corn and soybean seed industry in the United States to assess the welfare impact of genetically engineered (GE) crop varieties. We use a unique dataset, spanning the period 1996-2011, that contains rich information on the adoption of GE traits. Using a two-level nested logit model, we estimate that U.S. farmers a...

Delivering improved seeds to smallholder farmers in the developing world is an efficient and sustainable method of increasing crop yields and quality. Unlike fertilizers, pesticides and equipment, seeds can be produced locally for distribution to farmers or self-saved. Furthermore, improved varieties of horticultural crops often reduce dependence on synthetic pesticides, improve food safety, re...

We implemented a randomized field experiment in Malawi examining the impact of fingerprinting of borrowers, which improves the lender’s ability to withhold future loans from individuals who have previously defaulted while rewarding good borrowers with increased loan sizes. Study participants were smallholder fa...
