Technical Papers and Project Reports

Technical papers and project reports of the group "Economic and Agricultural Policy" at the Institute for Food and Resource Economics represent papers, notes and reports from project related work which serve as communication on current research efforts, typically towards the sponsors. They are usually not intended for journal submission in this form. An exemption are discussion paper published with international colleagues in discussion paper series of their institution. More general research papers by the group appear in the discussion paper series "Food and Resource Economics" or can be found under the category "journal publications" (both also on this website). Note that in opposite to discussion papers of our home insitution, we don't indicate here if versions of papers or reports list below have been published later as a peer reviewed journal article.

The authors are solely responsible for the release of technical papers and project reports. Comments, questions, and criticisms are welcome and should be sent to the authors directly. All citations need to be cleared with the corresponding author.
