当日のプログラム
セッション1(13:30-14:30)
報告者: 黒田 雄太 氏(東北大学)
論題: Future Educational Opportunities and Current Human Capital Investment: Evidence from Local School Markets
要旨: This paper studies whether subsidies for future schooling affect students before they reach the subsidized stage. I examine Japan’s private high school tuition support, exploiting staggered subsidy expansions across prefectures and linking nationwide middle-school achievement data to local high-school markets. The policy is associated with modest average achievement gains, but these gains are concentrated in markets where academically strong private schools are both accessible and financially attainable. In these markets, cram-school and tutoring participation also increase, especially in low-income schools, while study time does not. The results show that subsidies change preparatory investment only when they expand attainable academically prominent options.
セッション2(14:40-15:40)

論題: Combating Noise Pollution
要旨: Road-traffic noise imposes substantial welfare costs, yet the effects of noise regulation remain poorly understood, in part because long-run, large-scale noise measurement data are rarely available. We study Japan's Noise Prevention Act using noise measurements for roughly 17,000 road segments over 2002--2022 and document three findings. First, average roadside noise fell by 3 dB, corresponding to roughly 20% lower perceived loudness. Second, a trend decomposition indicates that noise policies account for over 80\% of this decline, with roughly equal contributions from tighter vehicle noise-emission standards and pavement upgrades. Third, a 1 dB noise reduction from pavement upgrades raises nearby residential land prices by approximately 3%. Our estimates imply that jurisdictions with weaker noise regulation -- including the United States -- leave substantial welfare gains unrealized.
セッション3(16:00-17:00)
報告者: 野村 魁 氏(東海大学)
論題: Rationality at Bin: Evidence from Tokyo
要旨: This study examines how the absolute and relative prices of designated waste bags affect household waste disposal and recycling behavior, particularly with regard to burnable waste, recyclable waste, PET bottles, and plastic packaging wastes. Using municipality-level data from 2000 to 2022, we estimate the effect of waste bag pricing using a two-way fixed effects model. The results show that higher overall waste bag prices are associated with changes in waste disposal and recycling, whereas the estimated effects of relative price differences are not statistically significant. These findings provide limited evidence that maintaining large price differentials between burnable and recyclable waste bags effectively promotes waste separation. The results highlight the importance of considering overall price levels, rather than focusing exclusively on relative price differences, when designing waste pricing policies.

第15回 CUESTセミナー(※第16回と同日開催です)
日時: 2026年7月29日(水)14:30-16:00

論題: From Bureaucrats to Municipal Officials: Revolving Door and Tax Enforcement Capabilities
要旨: This paper examines whether hiring retired National Tax Agency (NTA) officials can strengthen local fiscal capacity by transferring tax-enforcement-specific human capital to municipalities. Exploiting cross-municipality variation in the timing of such hires, we estimate the effects of these appointments on tax collection outcomes. We find that municipalities hiring retired NTA officials improve delinquent tax collection rates, with no detectable increase in tax administration spending. The gains are larger when retirees serve as regular staff but remain positive in guidance-oriented positions, suggesting both direct productivity effects and knowledge transfer. These findings show that reallocating specialized public-sector human capital may offer a cost-effective pathway to strengthening local fiscal capacity.

論題: Administrative Consolidation and the Cost of State Capacity
要旨: This paper studies how administrative consolidation affects the performance and cost of fiscal capacity. While consolidation may reduce administrative costs by exploiting scale effects, it may also disrupt the accumulated organizational resources and routines through which governments collect taxes. We examine this trade-off, focusing on Japan’s Great Heisei Municipal Mergers, a large wave of municipal consolidation in the early 2000s. Using an event-study based on a difference-in-differences design, we find that mergers reduce tax collection rates beginning in the pre-legal-merger transition period. In contrast, tax administrative costs fall only after formal consolidation, consistent with economies of scale in tax administration. We further find that tax revenue collected per unit of administrative cost increases after consolidation despite the decline in collection rates. These findings show that administrative consolidation weakens the collection margin of fiscal capacity during organizational transition, while lowering the resource cost of raising revenue enough to improve overall cost-effectiveness. The results highlight a trade-off between the operational performance and cost-effectiveness of fiscal capacity.
