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.

第14回 CUESTセミナー
日時: 2025年12月17日（水）16:10-17:40
場所: 千葉大学西千葉キャンパス文・法政経学部2号棟（演習室14）
報告者: 南 克典 氏（大阪大学）
論題: Growth Promotion Policies when Taxes Cannot be Raised
要旨: This paper examines the growth effects of R&D subsidies and public-funded basic research in an R&D-based endogenous growth model when political constraints do not allow the government to increase its revenue. If individuals have enough life-cycle saving motives and R&D productivity is sufficiently high, the growth rate becomes higher than the interest rate in equilibrium, and the government can finance expenses while perpetually rolling over the debt. Given this situation, debt-financed R&D subsidies always enhance short-run growth. However, they increase long-term growth only when R&D productivity exceeds another threshold. Our estimates suggest that this condition holds for most advanced countries, including the United States, but not for low-growth countries such as Japan and Italy. In contrast, enhancing public-funded basic research is effective for economic growth even in low-growth economies. How-ever, such policies reduce the upper bound in the debt-to-GDP ratio, beyond which the economy cannot recover to a steady state.
