The global agri-food system is experiencing a far-reaching transformation process. The consequences for small, asset-poor farmers are a topic of special concern in development oriented agricultural research. One main characteristic of the trend is the increasing importance of food safety 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 the past decades, a great interest has emerged in understanding the nature of people's well-being beyond consumption opportunities. It is widely believed that happiness research based on self-reports on people's satisfaction with life has made a significant contribution to this understanding....

In diesem Beitrag wird das Verbesserungspotenzial von Optimierungsverfahren im Vergleich zu empirisch beobachtbaren Programmentscheidungen der landwirtschaftlichen Unternehmenspraxis im Rahmen einer Fallstudie untersucht. Dazu werden für vier ausgewählte Brandenburger Marktfruchtbetriebe -...

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...

In the absence of formal financial markets, many poor households rely on risk sharing networks to protect themselves against adverse events. In this paper we present a model that explains the impact of formal insurance on informal risk sharing and, subsequently, the dynamics of other-regarding...

Bereits seit mehreren Jahrzehnten findet die Optimierung in der akademischen Lehre und Forschung starke Beachtung. Trotz der Breite potenzieller Anwendungsfelder gibt es jedoch einige methodische Schwierigkeiten. Das Hauptproblem besteht darin, die Unsicherheit, d.h. stochastische Prozesse von...

Empirical applications of real options models in competitive environments implicitly exploit the optimality of myopic planning. In a seminal paper [Leahy, J.V., 1993. Investment in Competitive Equilibrium: the Optimality of Myopic Behavior. Quarterly Journal of Economics 108, 1105–1133] shows...

An increasing number of herbicide‐resistant weeds challenge farming systems worldwide. Bans on active ingredients in chemical crop protection, which result in fewer weed control options, emphasise the importance of herbicide resistance management in arable farming. Resistance testing allows...
