Ökonomische Modellierung der Umweltwirkungen und Kosten des Biolandbaus auf Sektorebene

Summary

This paper presents a new approach to evaluate the cost effectiveness of agrienvironmental policies at agricultural sector level. On the basis of the sectorconsistent, comparative-static, farm group model FARMIS, the determinants of policy cost-effectiveness at sector level are addressed: Firstly, intensity levels for the FARMIS activities are defined in order to model uptake of agri-environmental policies with FARMIS, secondly, life-cycle assessment data is attached to these intensity levels to determine environmental effects of the policies and thirdly, public expenditure is calculated under consideration of transaction costs. This paper concludes discussing potential applications and the methodological challenges of the approach.
