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.
