Economic Modeling of Agricultural Systems

PD Dr. Wolfgang Britz

The focus of our work is on the development and application of economic simulation models from farm to global scale to analyze quantitative questions in the agri-food system related to sustainability and provision of eco-systems services.

Research

Recent research examples relate to optimal farm management and investment strategies in a changing market and policy environment considering risk, regional scale analysis of structural change and nutrient exchanges between farms in Agent-Based Models and long-term projections of the global food system.

Teaching

We offer courses at master level on the state-of-the-art of quantitative economic modeling of agri-food systems, allowing for hands-on experience with economic models developed and applied by us. After the successful participation in the courses offered by the Economic Modeling Goup, students can be granted the minor specialization "Economic modeling".

  • Bio-Economic Modeling at Farm-Scale
  • Partial and General Equilibrium Modeling
  • Applied Modeling of Agricultural Systems

We additonally offer  a one-week block course on advanced GAMS modeling in autumn as part of the "Doctoral Certificate Progam in Agricultural Economics" jointly managed by German speaking universities with an agricultural economics programs. That course will also be open for our master students.

Staff

Our team encompasses doctoral and post-doctoral researchers. We are located in Nussallee 19, ground floor.
