Research Abstract |
In order to discover the statistical facts about the dynamics of the market structure, "Market Share in Japan" (1972-2011 Eds.) by Yano Research Institute were computerized. Because the quantity of input work was far beyond the initial expectations, data entry has been completed at about the same time as the end of the study duration. Analysis of the data would be a future tasks. As for model, although it was initially expected to make improvements to the existing model to be able to explain the statistical facts obtained from the data analysis, because of the delay of data analysis, what was done was to make improvements to the part of the firm behavior of the model.
