摘要
Transition was characterized by massive structural changes in most economic sectors in Ukraine. This is especially true for the dairy sector. Several countervailing developments took place under transition that affected the dairy industry. Interregional trade became feasible, the importance of milk delivered by households increased significantly, and most dairies became investor-owned companies. The latter point and the fact that the Antimonopoly Committee of Ukraine detected several price cartels in the industry lead us to offer that after transition, dairies were able to exercise oligopsony power toward dairy producers at the regional level. This paper estimates market structure models for raw milk in Ukraine using a translog production function for the processing sector at the national and regional level. The results suggest the existence of oligopsony power in three of 25 administrative regions in Ukraine, coupled with a potential deviation of procurement prices for raw milk from the value marginal product of raw milk ranging from 24.6% to 49.4%. En Ukraine, la transition a entraine des changements structurels profonds dans la plupart des secteurs economiques, et plus particulierement dans le secteur laitier. Au cours de cette transition, plusieurs mesures ont ete mises en place, mais leurs repercussions sur l'industrie laitiere n'ont pas toutes ete benefiques. Le commerce interregional est devenu possible, la quantite de lait livree par les fermes s'est accrue considerablement et la plupart des laiteries sont devenues des societes par actions. Le fait que les laiteries soient devenues des societes par actions et que le Comite antimonopole de l'Ukraine (Antimonopoly Committee of Ukraine) ait detecte plusieurs cartels de prix au sein de l'industrie nous porte a dire qu'apres la transition, les laiteries ont ete en mesure d'exercer un pouvoir d'oligopsone au detriment des producteurs laitiers a l'echelle regionale. Le present article evalue les modeles de structure de marche du lait cru en Ukraine, a l'aide d'une fonction de production translog pour le secteur de la transformation a l'echelle nationale et regionale. Les resultats montrent l'existence du pouvoir oligopsone dans trois des vingt-cinq regions administratives de l'Ukraine, ainsi qu'un ecart entre les prix verses pour l'approvisionnement en lait cru et la valeur du produit marginal du lait cru, un ecart qui pourrait varier de 24,6 % a 49,4 %.
