Abstract
The empirical studies to the median voter hypothesis have been done all over the world widely. And some previous studies intended for Japanese case. Those previous studies have some points. The first point is that the estimation was intended for two or more annual expenditures. The second point is that they compared the mean income voter with the average income voter. However, these assumptions in the previous works don’t adjust to the setting of the median voter hypothesis. It is thought that an additional test is necessary to clarify the approval of the median voter hypothesis. This paper uses the variable to reflect the regional income distribution. If the median voter hypothesis is approval, the variable will not be significant. We estimate for total expenditure that aggregates voter’s preference for public goods. The result of the paper is that the income distribution variables are significant and interpretability of the estimated result of the average income person data was higher. This result shows that the median voter hypothesis is not approval unlike the previous works.
