Digital and Sustainable

Digital Transformation and Circular Economy

The group Digital Transformation and Circular Economy mainly uses experimental methods to investigate topics of sustainability and digitalization. Our goal is to learn more about individual decision behavior and essential elements that could lead to an economy which is more sustainable and digital in the future.

Head of Group Digital Transformation and Circular Economy


Our group has a broad field of research questions, considering topics of general economics, environmental economics, psychology and agricultural economics. Based on surveys, experiments and field data, we investigate various topics in these fields: first, we analyze economic preferences (e.g., risk attitude, loss aversion, time and social preferences) and the methodological approaches to elicit them. Second, we are interested in individual decision behavior: when, why and how do farmers/entrepreneurs invest? What drives the adoption of new (digital) technologies? Third, the group is interested in all kind of attempts to run a more sustainable economy. Here topics of water preservation, soil organic carbon, circular economy, the degradation of land and a loss of biodiversity are analyzed.

Climate Change and risk management in Agribusiness

This project aims to investigate how the effects of changing climate conditions are considered for agricultural production decisions. Due to climate change production has to adopt in the near future to maintain a productive agricultural sector.

Biodiversity and Sustainability

 For greater biodiversity and sustainability, (agricultural) production systems have to change. We investigated different approaches for a more sustainable agribusiness and investigate the adoption of these technologies on farms.

Digitalization and Circular Economy

Digital technologies gaining importance in agriculture. On the one hand these new technologies and their application has to be evaluated. On the other hand, digital technologies might improve the circularity of our economy. Both of these paths are focused in this project.


Our goal and ambition in teaching is to equip students with skills that will facilitate their path to personal success in their career. We want to promote the intrinsic motivation of students. Therefore, the connection of teaching to our current research is particularly important.
