Abstract

Zusammenfassung : Das Ziel der vorliegenden Arbeit besteht in der Bestimmung der Betriebsaufgabewahrscheinlichkeit verschiedener Betriebstypen im Westen Deutschlands in Abhängigkeit von Gewinnniveau und Gewinnentwicklung. Dabei wird davon ausgegangen, dass die Reaktion der Betriebe auch von der erwarteten Nachhaltigkeit der Gewinnschwankungen sowie von der Betroffenheit anderer Betriebe abhängt. Es wird deshalb auch erwartet, dass die Betriebe in Abhängigkeit vom regionalen Kontext unterschiedlich reagieren. Die Gewinnerwartung der Betriebe wird mithilfe des Testbetriebsnetzes des BMELV geschätzt. Die Betriebsaufgabewahrscheinlichkeit wird in einem zweiten Schritt anhand der flächendeckenden Daten der Agrarstrukturerhebung in einem logistischen Modell für verschiedene Betriebstypen bestimmt. Schließlich werden in einem Metamodell die Ursachen für die regionalen Unterschiede der Schätzkoeffizienten untersucht. Die Annahmen bezüglich der differenzierten Wirkungen betrieblicher Gewinnschwankungen auf die Betriebsaufgabeentscheidung werden weitgehend bestätigt. Zentrale Fragen für die zukünftige Forschung mit längeren Zeitreihen werden identifiziert. --------------------------------------------------------------------------------------------------------------------------------------- This working paper aims at the determination of the impact of different profit-levels and changing profits upon farm-exit probabilities of different farm-types in western Germany. It is expected that the farms’ reaction depends on the sustainability of profit-changes as well as on the other farms’ concernment. Therefore we also expect that farms show het-erogeneous reactions depending on the regional context. Farms’ expected profits are es-timated with the help of the German Farm Accountancy Data Network (FADN). Farm-exit probabilities are estimated in a second step within a logistic model based on micro data from the farm structural survey. Finally possible causes for heterogeneous estimators are explored in a meta-model. The assumptions concerning the heterogeneous effects of changing profits are confirmed by the results. Central questions for future analyses with longer time-series are identified.
