Wolfgang Britz


Head of Group
Economic Modeling of Agricultural Systems

PD Dr. agr., Senior Lecturer and Researcher


Nussallee 19, Haus 2, room 0.008 (ground floor)
Tel.: ++ 49 - 2 28 - 73 29 12

Wolfgang Britz is senior researcher and lecturer in a tenured position at the Institute for Food and Resource Economics, University Bonn, where his research focus is on the impacts of agricultural, environmental and trade policies on the agricultural sector, the environment and rural areas based on quantitative analysis with different types of economic simulation models. Since 2017, he heads the Economic Modelling of Agricultural Systems group after temporarily heading the "Production Economics" chair in 2016.

More ...
Dr. Britz regularly consults governments and international organizations such as the EU Commission, OECD or FAO based on quantitative impact assessments and in methodological matters relating to economic simulation models.

He developed the first versions of the CAPRI modelling system and contributed until 2012 to its evolvement as a global economic simulation model for trade in agricultural and food products combined with detailed bio-economic supply models for European agriculture, including coordinating large-scale EU funded research projects focusing on CAPRI.
