Farmers do not often change from their house bank to another bank, even if the competing banks offer better conditions. This “reluctance to switch” can be explained, on the one hand, by the transaction costs resulting from such a change of business relation. On the other hand, it may be the...

Die Effizienzanalyse mit Hilfe der Data-Envelopment-Analyse (DEA) stellt ein weit verbreitetes Verfahren zur vergleichenden Einschätzung der empirischen Performanz von Entscheidungseinheiten (z.B. Unternehmen) dar. Angesichts „boomender“ Anwendungen auf eine Vielzahl...

In this paper we examine whether there is room for improvement in farm program decisions through the integration of formal mathematical optimisation into the planning process. Probing the potential for improvement, we investigate the cases of four Brandenburg cash crop farms over the last six...
