Details	This research subject has two themes: In (Research 1), in order to enable accurate and nuanced analysis, strategic behaviors of manufacturer vs. retailer are modeled using the Nash bargaining. Then, we propose a structural model of expressing the competitive state of each channel and conduct empirical analysis. Special attention is paid to so-called "disagreement payoffs"incurring to the agensts when negotiations fail. . In (Research 2), we start with the assumption that the conventional discrete choice model is not properly represented by a geometry suitable for it and, as a result, that no statistical estimation method suitable for the model has been proposed, we will deepen our understanding of the model and its underlying utility under more appropriate Aitchison geometry.. , And propose an estimation method that is consistent with it.
