(The Cause of Changes in Beef Marketing Margin)

This paper investigates factors affecting the beef wholesale-retail marketing margin. Especially, the effects of the increasing market share of the large scale retailers on the beef wholesale-retail marketing margin was investigated. The structural model was constructed for the beef marketing margin which is mainly composed of the demand and supply at beef retail as well as wholesale market. An appropriate empirical econometric model was estimated using annual data from 1975 through 2008. Based on the results, this paper finds empirical evidence that beef marketing margin tends to be increased as the oligopsony power increased and to be reduced as imports and industrial production index are increased.
