Outline of Final Research Achievements |
This study conducts empirical analysis focusing on the impact of tax changes on output in Japan. Adopting the narrative approach pioneered by Romer and Romer (2010), I analyzed the motivations for tax changes and classified them into 187 endogenous changes and 401 exogenous changes. The impact of tax on output is substantial and persistent. A 1 percent of tax changes were associated with 1.5 percent decrease in output on impact, then output decrease gradually, reaching negative peak of -3.6 percent in three years. The findings closely align with those of Romer and Romer (2010) for the U.S. and with the research conducted by Cloyne (2013) for the U.K.

Academic Significance and Societal Importance of the Research Achievements |
経済成長を税制改革の目標として設定するためには証拠が必要となるが,実証上の難点が指摘されてきた.マクロ経済の変動と無関係な租税政策のショックデータを識別することには困難がある.これは同時決定問題といわれている.本研究は,ナラティブアプローチを用いて,この問題に対処した.識別された外生的租税政策のショックデータを対象にして,構造VARや分布ラグモデルを使用して,税の変化がマクロ経済に及ぼす効果を推定すれば,「減税は景気を回復させるか」「増税は景気回復の足かせになるのか」といった公共政策の重要問題に対して,証拠にもとづいた政策的指針を与えることが期待できる.
