     View Summary

    We investigate effects of reform of spousal tax deductions, which were listed in the 2017 tax reform outline, and deductions for persons on income inequality in Japan by using a microsimulation. The Japan Household Panel Survey (JHPS) in 2014 is used in the analyses. We find that the reform of exemptions for spouses does not substantially correct income disparity. It implies that the spousal tax deductions after the reform still remain as deductions from income (tax allowances), which have weaker effects in correcting income disparity relative to deductions from tax. In addition, we analyze a microsimulation which changes deductions from income to tax credits. That is, the reform in which deductions from income are abolished and tax credits based on household composition are newly established on only deductions for persons. We obtain the result that the Gini coefficient of the equivalent household disposable income slightly decreases. In order to decrease the Gini coefficient more, even deductions from earnings (deduction for employment income and deduction for public pensions) need to be abolished and tax credits need to be newly established. Moreover, according to a microsimulation, a "discount on social insurance premiums (tentative name)," which provide for partial compensation of premiums by using revenue from the personal income tax, acts to correct income inequality.

     View Summary

    This study focuses on intergovernmental relationship as problems of "Tragedy of the Commons." We obtain the main following results through both theoretical and empirical analyses. In a theoretical one, herd behavior of local governments are observed when they are risk-averse, and it lowers economic growth, which expects to be enhanced by an innovative policy. In an empirical study, such herd behavior is observed using regional variations in vaccination subsidy amount within Japan's current immunization program. Also, the same tax base of national and local taxes can be recognized as a commons. We examine a simulation analysis of corporate tax reform using a dynamic general equilibrium model, since national corporate tax and corporate income tax are the same tax base, and obtain results that labor income totally increases after the reform, but partly decreases by an increase in size-based business taxation of local tax.

  • Dynamic General Equilibrium Analysis of the Incidence of Corporate Income Tax

     View Summary

    Incidence of corporate income tax is an old and new problem in public economics. In Japan, under discussion on the tax reform, raising consumption tax (VAT) will be needed and the burden of corporate income tax is heavier than other countries. Against the argument, there is an objection that the policy package of consumption tax increase and corporate income tax cut is politically unacceptable. In the background, it is intuitively thought that consumption tax is mainly beard by consumers and corporate income tax is mainly beard by corporations. Such asserters ignore the previous studies of the shifting and incidence of corporate income tax.
    In such present situation, it is necessary to examine analysis of the incidence of corporate income tax to discuss the hereafter tax reform, especially consumption tax increase and corporate income tax reduction. In this research, we build a theoretical model to investigate tax incidence, and implement numerical analysis.
    Static analysis of incidence of tax started from the pioneering study by Harberger in 1962 had been developed into dynamic analysis to consider the intertemporal resource allocation. On the other hand, about the analyses of the tax reform in Japan, the simulation analyses prospered in the late 1980s when consumption tax (VAT) was not be introduced, and some analysis were done in the mid 1990s when the tax system was revised. But such analyses are scarcely made in recent years. In addition, the previous simulation analyses of tax reform mainly focus on the loss and gain of each agent with tax reform. These analyses do not prove the incidence of the burden of corporate income tax clearly.
    Recently, in the US, several scholars implement numerical analyses of the incidence of corporate income tax. However, they employ a static model without corporate finance. Unfortunately, there is no empirical study on it in Japan over a few decades.
    In this research, while considering the tide of this precedent study, we focus on the incidence of the burden of corporate income tax and analyze it on the basis of Japanese tax system and macroeconomic data. Especially, it is necessary to consider in the dynamic macroeconomic model that can analyze it to explain the intertemporal incidence. By building dynamic macroeconomic model, it is able to analyze not only the instantaneous incidence of corporate income tax but also consider the intertemporal incidence.
    In the short run (for one year), a percentage of the incidence on labor income is about 50-80%, and a percentage of the incidence on capital income is about 20-50%. In the long run, about 95% of the incidence is on labor income. Almost all of the incidence is shifted to labor income, but not all of the incidence is.
