□13:00-13:10 開会挨拶
□13:10-13:50 第1報告
報告者:萩原健史(京都大学大学院経済学研究科・博士後期課程)
報告論題:Aging and its macroeconomic consequences: An inverted U-shaped
endogenous economic growth
報告要旨:This study theoretically analyzes population aging and its
impacts on economic growth, wealth inequality, and fiscal
sustainability. We introduce lifetime uncertainty to the overlapping
generations model with heterogeneous households with varied
intertemporal preferences, where unintended bequests caused by death
are inherited by offspring. Aging can have both positive and negative
impacts on economic growth and fiscal sustainability: saving-enhancing
effects based on the life cycle theory and wealth-depletion effects
caused by extended longevity. When aging advances, saving-enhancing
effects are offset by wealth-depletion effects, which eventually
outweigh the former. The results show an “inverted U-shaped”
relationship between life expectancy and economic growth rate, or
fiscal sustainability. Numerical simulation reveals that aging can
produce a trade-off between economic growth and wealth inequality. We
also show that a rise in deficit or government expenditure ratio
exacerbates fiscal instability, economic growth, and wealth inequality
under certain conditions.

□14:00-14:40 第2報告
報告者:加藤悠太(京都大学大学院経済学研究科・修士課程)
報告論題:Escaping the Middle Income Trap: The Role of Strategic Public
Investment and Industrial Structural Change
報告要旨:This study examines how the middle-income trap occurs in
developing economies and how fiscal policies and development
strategies can help countries avoid or escape this development
challenge. Using a dual-sector model with public investment in
infrastructure and education, we analyze how different policy choices
affect growth trajectories and development outcomes. The findings
suggest that appropriate fiscal policies and investment strategies are
crucial for avoiding development traps and achieving sustainable
economic growth, but insufficient infrastructure investment and high
tax rate can lead to stagnation of industrialization and economic
development, potentially leading to a middle-income trap. The model
also reveals an important relationship between poverty traps and
middle-income traps, showing that even after escaping from initial
poverty through external assistance, countries need appropriate fiscal
policies to achieve sustainable development.

□14:50-16:10 第3報告
報告者:二宮健史郎(立教大学)
報告論題:Financial Structure and Monetary and Fiscal Policies
報告要旨:The financial instability hypothesis of the heterodox economist
H.P.Minsky came to the fore as a result of the international financial
crisis triggered by the sub-prime mortgage crisis in the U.S. Many
post-Keynesian economists have developed Minsky’s arguments into
mathematical models that depict two types of Minskian financial
structures, which we identify as the lenders’ risk type (LR) and the
hedge, speculative, and Ponzi type (HSP). We examine the effects of
monetary and fiscal policy in macrodynamic models that consider both
the LR and HSP financial structures. We demonstrate that the effects
depend on the significance of those structures. We emphasize the
significance of stable financial structures and the mix of monetary
and fiscal policies needed to stabilize the economy. However, we show
that the policy mix is not able to eliminate the fragility of the HSP
financial structure completely.

□16:20-17:40 第4報告
報告者:平野嘉孝(富山県立大学)
報告論題:スラッファの存続可能性と剰余概念
報告要旨:産出量で投入量を割り技術係数に変換することをせずに、
経済分析を行うことを「商品の生産図式」を用いると呼ぶことにする。
「商品の生産図式」を利用し、主に数値例を用いて、
「自己でないものを補填する」状態の分析装置としての意義を問い直す。
また、最小単位の主体は代表的企業ではなく、商品であることの分析的含意にもふれる。
以上の分析を踏まえ、スラッファ文書も利用し、スラッファの剰余概念を再考する。
司会者:黒瀬一弘(東北大学)
