Outline of Final Research Achievements

In this project, we conducted an empirical analysis of the effect of the consumption tax hike on the price level by industry, using data on the consumer price index by industry. The results obtained show that the effect of the consumption tax hike on price pass-through (pass-through) in Japan varies by industry. Specifically, we found that the situation was different for education, utilities, and water supply, where price pass-through occurred almost exclusively due in part to the inclusion of tax-exempt items, and for education and entertainment, where we observed what could be considered a price-overshifting.
In addition, since the study was faced with the Corona disaster during the period of this study, we also analyzed the effects of individual subsidies called "Go to Travel.

Academic Significance and Societal Importance of the Research Achievements

本研究の意義としては、消費増税による価格転嫁の度合を見ることで、産業ごとへの影響度合いを明らかにし、物価上昇という増税が経済厚生に与えるコストを定量的に評価することにある。また、便乗値上げが生じるような産業においては、不完全競争に直面しており、産業としての競争度が損なわれていることを示唆するものである。
