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...

Climatic risks are a major challenge for rural communities, especially those whose livelihoods directly depend on agriculture. Weather extremes affect crop productivity not only through the direct relationship between weather variables and yields, but also through the negative effects of such...

This thesis addresses 3 different aspects of food and poverty related problems in developing countries. The first essay presents a new operational concept of transaction costs that firstly allows assessing the magnitude and secondly recognizing the non homogeneity of food products. This is...

Benefit incidence analysis is an extremely popular tool to assess the distribution of benefits from government expenditure in developing countries, particularly in the social sectors. The analysis describes the welfare impact of public spending on groups of people or households, typically along...

The expansion of supermarkets in developing countries may have far-reaching consequences for poverty and rural development. While previous studies have compared farm profits between participants and non-participants in supermarket channels, wider household welfare effects have hardly been...

Supermarkets and high-value exports are currently gaining ground in the agri-food systems of many developing countries. While recent research has analyzed income effects in the small farm sector, impacts on farming efficiency have hardly been studied. Using a survey of Kenyan vegetable growers...

Most micro-level studies on the impact of agricultural technologies build on cross-section data, which can lead to unreliable impact estimates. Here, we use panel data covering two time periods to estimate the impact of tissue culture (TC) banana technology in the Kenyan small farm sector. TC...

Classical innovation adoption models implicitly assume homogenous information flow across farmers, which is often not realistic. As a result, selection bias in adoption parameters may occur. We focus on tissue culture (TC) banana technology that was introduced in Kenya more than 10 years ago. Up...

This article investigates determinants and impacts of cooperative organization, using the example of smallholder banana farmers in Kenya. Farmer groups are inclusive of the poor, although wealthier households are more likely to join. Employing propensity score matching, we find positive income...
