Welcome to the Agricultural and Food Market Research Group!
Our research group analyzes in an interdisciplinary team - consisting of agricultural economists, psychologists as well as nutritional, sustainability and political scientists - the behavior of consumers and other stakeholders in the value chains of the agri-food sector. In our research projects, we gain knowledge on how the transformation process, that is necessary to achieve the sustainability goals, can be promoted.
Thank you for your interest in our website!

The research of our team focuses on the analysis of determinants and effects of ecologically, socially, and economically (un)responsible actions of stakeholders in the agricultural and food sector - this ranges from production and processing to consumption and also includes the consideration of institutional framework conditions. Based on this, we investigate the potential of market strategies as well as the role and legitimacy of policy interventions in initiating and transforming the food sector towards more sustainable ways of production and consumption. The spectrum of the research work of the research group covers the following issues:
- Which factors influence the acceptance of citizens and actors in the food value chain with regard to new, more sustainable technologies, products, and social innovations in the agricultural and food sectors?
- How do consumers make their food choices? What role do attitudes, social norms and habits play in explaining behavior?
- How do actors in agriculture, the food industry, and the grocery trade react to new consumer and policy demands regarding the safety and sustainability of products and processes?
- How can sustainable development take place in a competitive and increasingly concentrated agricultural and food sector?
- How do actors on the agricultural and food markets deal with conflicting objectives?
