| Outline of Final Research Achievements |
The aim of the study is to clear the decision mechanism of the premium and the subsidies in the municipality-based health care insurance system in Japan. In the research, I address two questions: first, whether does the subsidy mechanism bring the differences of inefficiency of service use? Second, whether do political factors such as seniority of a mayor or structure of an assembly affect the decision of premium rate?
First, I compared the health care insurance with the long-term care insurance in a same municipality. Employing the stochastic cost frontier model, I showed the difference of the inefficiency in two systems. The inefficiency of the health care system was larger than that of LTC.
Second, I estimated the regression of the premium equation on the seniority of a mayor and other political factors with some control variables. The estimation result showed that just the seniority of a mayor was positively significant, and other political factors were not significant.
