An Agro-Economic Production Model for a Middle European River Basin - First Results of CAP Reform Scenario Calculations AgEcon
Henseler, Martin; Krimly, Tatjana; Wirsig, Alexander.
ACRE is an Agro-eConomic model for agricultural pRoduction on rEgional level. Based on an extension of Positive Mathematical Programming (PMP) this model was developed as a decision tool for politics with respect to questions of global change- and political scenarios. Currently, ACRE is applied in the RIVERTWIN-Neckar project and politic scenarios of the CAP reform 2003 were calculated. This paper introduces ACRE, its theoretical framework, and the first results of political scenario calculations, which where done for the Neckar river basin.

Development, Testing and Application of ACRE: An Agro-Economic Production Model on Regional Level AgEcon
Henseler, Martin; Wirsig, Alexander; Krimly, Tatjana.
ACRE is an Agro-eConomic model for agricultural pRoduction on rEgional level. Based on an extension of Positive Mathematical Programming (PMP) this model was developed as a decision tool for politics with respect to questions of global change scenarios. The validity of the theoretical approach as well as the algorithms has been tested by calculations with empirical data. Currently, ACRE is applied in large interdisciplinary projects. This paper introduces the development of ACRE, from the theoretical framework to testing its validity and current application.

DIE EU-ÜBERGANGSREGELUNG ZUM HERKUNFTSSCHUTZ BEI AGRARPRODUKTEN UND LEBENSMITTELN AUS DEM BLICKWINKEL DER TRANSAKTIONS- UND DER INFORMATIONSÖKONOMIE AgEcon
Benner, Eckhard; Profeta, Adriano; Wirsig, Alexander.
Seit mittlerweile 15 Jahren besteht mit der Verordnung (EWG) Nr. 2081/92 ein europaweites Schutzsystem für geografische Angaben bei Agrarprodukten und Lebensmitteln. Der Beitrag analysiert auf Grundlage Informationsökonomie und der Transaktionskostenansatzes diese Regelung. Die Analyse zeigt, dass trotz der Neuformulierung der Verordnung im Jahr 2006 weiterhin auf Seiten der Verbraucher die Gefahr der Irreführung besteht und die Regelung der deutschen Ernährungswirtschaft hohe Transaktionskosten verursacht. Ursächlich dafür verantwortlich ist der Kerngedanke der Verordnung, Namen solcher Produkte gegen missbräuchliche Verwendung im Wettbewerb zu schützen, die vom Wesen her als Original aufgrund eigener Geschichte, eigener Rezeptur bzw. besonderer Qualität...

The influence of climate change, technological progress and political change on agricultural land use: calculated scenarios for the Upper Danube catchment area AgEcon
Henseler, Martin; Wirsig, Alexander; Krimly, Tatjana; Dabbert, Stephan.
Both climate and agricultural policy changes are commonly seen as important drivers for agricultural production. In this study, scenarios of climate and political change were calculated for the Upper Danube catchment area using the regional optimization model ACRE. Two political scenarios were calculated for the year 2020. One scenario assumes the continuation of the Common Agricultural Policy reform 2003 the other assumes a strong shift away from payments of the first pillar to payments of the second pillar of the CAP. Both scenarios were combined with four different scenarios of climate change and technological progress derived from ICCP SRES assumptions and the ACCELERATES project. The results of the scenario calculations were analysed with respect to...
