Productivity and efficiency are key performance indicators of improved seeds. Efficiency differences explain part of the variation in productivity. Improved seeds may affect efficiency because farmers often do not apply inputs at optimum. Improved seeds therefore not only directly affect...

With the modernization of global agri-food systems, the role of contract farming is increasing. This also involves smallholder farmers in developing countries. While previous studies have looked at economic impacts of contract schemes on smallholder farmers, little is known about farmers'...

Farmers' preferences for sustainability certification are analyzed, building on a choice experiment conducted with smallholder coffee growers in Uganda. Farmers have positive general attitudes towards certification. While they dislike bans of productivity-enhancing inputs, benefits associated...

In many developing countries, supermarkets are expanding rapidly. This also affects farmers’ marketing options. Previous studies have analyzed welfare effects for smallholders with crosssection data. Here, we use panel data and a differencing approach to study supply chain dynamics and better...

Commercialization of smallholder agriculture is widely seen as an essential pathway towards rural economic growth. While previous studies have analyzed effects of commercialization on productivity and income, implications for farm household nutrition have received much less attention. We...

Millions of smallholder farmers in developing countries participate in different types of sustainability standards. A growing body of literature has analyzed the welfare effects of such participation, with mixed results. Yet, there are important knowledge gaps. First, most existing studies look...

The food retail sector in many developing countries is transforming with a rapid growth of modern supermarkets. Supermarkets are not only influencing how food is sold to consumers, but also how agricultural products are sourced from farmers. Especially for the procurement of fresh fruits and...

We analyze how agricultural extension can be made more effective in terms of increasing smallholder farmers' adoption of pro-nutrition technologies, such as biofortified crops. In a randomized controlled trial with farmers in Western Kenya, we implemented several extension treatments and...

In many developing countries, supermarkets are increasingly replacing traditional markets as preferred points of food purchases in urban areas. This has welfare implications on smallholder farmers that supply supermarkets. While previous studies have analyzed the welfare effects of smallholder...

In this paper we study the dynamics of smallholder participation in export value chains focusing on the example of small-scale broccoli producers in the highlands of Ecuador. We analyze the extent of participation over an 11-year time period using correlated random effects and diff-GMM models...
