Outline of Final Research Achievements

The most of traditional legal theories of tax law assume rationality of taxpayers. Through this project, I found the ways of improving tax law legislation by taking into account “bounded rationality” of taxpayers, which is studied in the field of behavioral economics and behavioral finance.
As to the main research purpose, this project considers the hidden problems of “implicit contingent liabilities”, which could cause the bankruptcy of the Japanese government in the future. And I found, by matching the fiscal systems (i.e. tax law and public finance law) with other legal systems, we could reduce these future fiscal risks resulting from implicit contingent liabilities.
