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	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 interaction and evaluate the spatial autocorrelation coefficient changes between the Kanto and Kansai regions using the institutional and informational changes in the development policy in the 2010s. The estimation results show that the “blog frenzy” of 2016 increased media coverage in the Kansai urban area and significantly raised the spatial autocorrelation coefficients on the public and total provision rates compared to similar local governments in the Kansai region. By contrast, the “Zero Children on Waiting Lists Declaration” by the City of Yokohama in 2013, which marked a turning point in the development policy of the Kanto region, had no region-specific effect on spatial autocorrelation. This result may be due to the regional nature of the event and the regional and temporal differences in local governments’ responses.

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.
