報告 | 髙橋 済 (Wataru Takahashi)(高崎経済大学) Interactions among Local Governments over the Provision of Nursery Facilities: A Quasi-Experimental Approach [Paper] |
要旨 | The development policy for nursery facilities has become an important issue in Japan in recent years. We thus examine the existence of a strategic interaction among local governments over the provisioning policies for nursery facilities by estimating their reaction function. To this end, we employ a quasi-experimental framework to validate the strategic |

報告 | 持田信樹 (Nobuki Mochida) (中央大学) Macroeconomic Impact of Tax Shocks: Evidence from Japan Using a Narrative Approach [Paper] |
要旨 | This paper analyzes the effects of tax shocks on the economic activity. Following David and Christina Romer's narrative approach, we identify, from scratch, 486 tax changes enacted in Japan into endogenous tax changes motivated by the state of the economy and more exogenous tax changes . These provide new datasets following those for the US and UK. We found that exogenous tax changes have a large and long- term impact on the economic activity in Japan as well. Exogenous tax shocks negatively impact the GDP trajectory, with consumption as the main transmission channels. In other words, tax cuts motivated by a desire to raise long-term growth have a positive effect on consumption, thereby increasing GDP. Deficit- driven tax changes have a negative effect on residential investment but has a positive effect on corporate investment, thereby increasing GDP. |

報告 | 後藤剛志(千葉大学) Tax-Price Elasticities of Charitable Giving and Selection of Declaration: Panel Study of South Korea [Paper] |
要旨 | This study estimates the tax-price elasticity of donations, addressing the bias caused by the existence of nondeclared giving and presenting the estimation method based on the intention-to-treat analysis to eliminate the bias. Using the method and the exogenous variation of tax incentives in the 2014 South Korean tax reform, we estimate that the giving price elasticity is -1.6, more elastic than the standard results. The control function approach confirms similar results and shows that less declaration of those with large amounts of donations without tax incentives causes the elasticity to be incorrectly estimated to be inelastic. |

報告 | 小林克也 (法政大学) Effort complementarity and role assignments in group contests [Paper] |
要旨 | This study characterizes role assignments in maximizing a group’s winning probability under the influence of the complementarity of group members’ efforts in a group contest, in contrast to prize and multiple resource allocations. We use a CES effort aggregator function to parameterize the complementarity. While the prize and resource allocation rules depend on the complementarity, the assignment rule does not when multiple roles are assignable to a single group member: All roles are assigned only to the most productive group member. However, when only a single role per group member is assignable, the assignment rule depends on the complementarity: Roles from greater to less importance are assigned to group members in descending order of their productivity under strong complementarity; only the most important role is assigned to the most productive group member and the others have no effect under weak complementarity.

報告 | 盛本圭一(明治大学) Global Corporate Income Tax Competition, Knowledge Spillover, and Growth (joint work with Noritaka Maebayashi) [Paper] |
要旨 | We analyze the welfare consequences of global corporate income tax competition, using a two-country model of endogenous growth with international knowledge spillovers. Although the Nash equilibrium tax rate can be excessively high or low, according to the degree of spillover, this does not lead to significant welfare losses. The key to this outcome is that corporate income tax competition for growth maximization, which we consider hypothetically, attains the maximum growth rate, despite complex externalities and strategic interactions. |

報告 | 大野太郎(財務省) 個人所得課税の自動安定化効果 |
要旨 | 我が国における個人所得課税の研究では家計マイクロデータを使用した取り組みが進む中、マイクロシミュレーションという手法を扱う研究も増えている。これは各世帯の家族構成や収入の情報から、世帯ごとの税額を推計するもので、これを利用して例えば税制改正の影響を試算することも可能となる。こうしたマイクロシミュレーションの活用は幅広く、海外では税制・社会保障制度の安定化効果(所得変動縮小の度合い)についても考察されてきた。他方、日本において同様の考察は少ないが、家計はコロナ禍をはじめ断続的に所得変動に直面しており、税制・社会保障制度による安定化機能は一層期待されている。本報告では税や社会保険料の安定化効果を計測し、現行制度におけるビルトイン・スタビライザーの大きさについて定量的な評価を行う。その際、マイクロシミュレーションを活用することにより、他の要素を一定とし、当該制度のみがもたらす安定化効果の大きさを計測することが可能となる。また、安定化効果の時点間比較について要因分解を行い、制度変更による真の寄与についても計測する。 |

報告 | 高松慶裕(明治学院大学) Optimal policy mix of in-work benefits and unemployment benefits: The case of misusing unemployment benefits |
要旨 | We investigate the optimal combination of labor income taxation and search-contingent unemployment benefits in an economy where some job seekers may fail to find job offers. When a household receives a job offer, it must decide whether to accept it. Households receive unemployment benefits only if they actively seek jobs but remain unemployed. We assume that the government cannot distinguish between a job seeker who does not receive a job offer and one who rejects a received offer. Therefore, if the size of the unemployment benefit is sufficiently large, it may be misused by households that are not willing to accept jobs but pretend to be actively searching. We derive optimal rules for employment tax and search-contingent unemployment benefits, and we show that the optimal size of unemployment benefits is likely to be positive. Our numerical simulations suggest the following: (i) Implementing an in-work benefits policy for low-income workers is beneficial. (ii) The optimal size of unemployment benefits is large, making it desirable for the government to intentionally permit some households to misuse them. (iii) Frictions in job markets affect the desirability of in-work benefits and search-contingent unemployment benefits. |

Does the electronic filing system (e-tax) reduce tax evasion? Evidence from Japanese corporations 2) 17:05-18:45 石田三成(東洋大学) The Impact of Pay Cuts for Public Officials on Misconduct: An Empirical Analysis Focusing on the Differences between Shirking and Corruption (joint with Hidemasa Yoneoka) |
要旨 | 1) With the rapid progress of Information and Communication Technology (ICT), the digitalization of administrative processes in governments has gained much attention. The electronic filing (e-tax) for corporate tax returns is one of the practical examples. This paper investigates the effect of introducing an e-tax on tax evasion behavior using a policy reform in Japan that mandates large corporations to adopt e-tax. We apply difference-in-differences methods to find that the introduction of e-tax reduces amendments to declaration, which can potentially become unintentional tax evasion, by about one-third. On the other hand, we cannot find any evidence that e-tax reduces intentional tax evasion. 2) There are numerous empirical papers on corruption to date, but corruption is only a small part of the misconduct of public officials. According to the efficiency wage hypothesis, salaries should affect not only corruption but also shirking. Therefore, this paper focuses on the event that the Japanese Government requested local governments to reduce the salaries of local civil servants in 2013 in order to raise funds for reconstruction following the Great East Japan Earthquake in 2011, and estimates the impact of salary reductions on shirking and corruption by using PSM-DID respectively. Our results support the efficiency wage hypothesis, showing a significant increase in both shirking and corruption in municipal governments that implemented the pay cut compared to those that did not. |
