• In this paper, we present a conceptual bilateral oligopoly model for measuring the degree of "vertical power balance" or the comparative degree of market power between sellers and buyers in Japan's fluid milk market. The model also simultaneously measures the degrees of horizontal competition among sellers, as well as horizontal competition among buyers. We estimate the model based on available data and several simplifying assumptions, in order to illustrate how the model could be tested. The results presented here are tentative due mainly to data constrains, but they constitute the first economeric evidence supporting the general perception that retailers, through they face nearly perfect horizontal competition among each other, have extremely dominant vertival market power over fuid milk processes. Also, the results constitute the first econometric evidence that processors may have some vertical market power over dairy cooperatives.
