ブキャナンの財政学への貢献

抄録

This paper considers Buchanan’s contribution to public finance and points out how it can contribute to current public finance in Japan. Buchanan contributed to public finance in three ways. First, he analyzed public finance by not supposing on impartial and benevolent government that maximizes social welfare. Second, he dealt with collective decision making in budget processes. Third, he explored constitutional choice among alternative institutions of public finance.

　The suggestion his contribution makes to current public finance in Japan is as follows. We should make clear not only the difference between debt finance and money creation but also the difference between taxes and insurance premiums as a constitutional reform. Japanese people have to seek a path to overcome grave deficit dependence from our own viewpoint, by referring the generality principle that Buchanan claims as a constitutional reform.
