While many studies analyzed effects of sustainability standards - such as Fairtrade or Rainforest Alliance - on smallholder farmers in developing countries, most did not sufficiently account for systematic differences between certified and non-certified farmers. Certified farmers are typically...

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...

Global poverty rates have declined considerably, but the number of people living in extreme poverty remains high. Many of the poor are smallholder farmers. Agricultural commercialization - meaning a shift from subsistence to more market-oriented farming - can play a central role in improving...

While there is rich literature covering theoretical concepts of transaction costs very few empirical strategies have been provided to estimate them. The theoretical framework proposed in this paper is based on a unit value decomposition and dedines transaction costs as the difference between a...

It is often assumed that voluntary sustainability standards - such as Fairtrade - could not only improve the socioeconomic wellbeing of smallholder farmers in developing countries but could also help to reduce negative health and environmental impacts of agricultural production. The empirical...

GlobalG.A.P. compliance has often become a key requirement for farmers to access high-value global markets. Yet, the global spread of certification is highly uneven among countries. We assess the drivers and dynamics behind these unequal patterns, applying panel data regressions. Findings show...

In the existing literature, the effects of contract farming on household welfare were examined with mixed results. Most studies looked at single contract types. This paper contributes to the literature by comparing two types of contracts - simple marketing contracts and resource-providing...

Contract farming is typically seen as a useful mechanism to help smallholders. However, despite economic benefits, high dropout rates from contract schemes are commonplace. We use data from Ghana to show that smallholders benefit from a resource-providing contract in terms of higher yields and...

We analyze the gender price gap (GPG) in Central Kenyan vegetable markets. Exploiting differences in the combination of the gender of the household head, the person controlling production, and the seller, we control for other gender related influences. We cannot identify a significant GPG for...

Using survey data from Central Kenya, I find that the difference in prices received by female compared to male vegetable traders changes significantly in men's favor when the size of the transaction increases, ceteris paribus. This pattern in the price gap drives a gender difference in the value...
