Oligopsony Power with Uniform Spatial Pricing: Theory and Application to Milk Processing in Spain
Posted: 24 Dec 2000
This study presents a conceptual and empirical analysis of buyer oligopsony power in a spatial markets setting. The conceptual model analyses behaviour in a market with uniform spatial prices and Loeschian conduct. A key result is that firms may set prices above the monopsony level to minimise direct competition among themselves. The empirical analysis focuses on the purchase of milk in the Asturias region of Spain and utilises a panel of firm-level data to study the determinants of milk processors' pricing behaviour. Estimation results strongly support the predictions of the theoretical model.
