In distilling a vast literature spanning the rational- irrational divide, this paper offers reflections on why asset bubbles continue to threaten economic stability despite financial markets becoming more informationally-efficient, more complete, and more heavily influenced by sophisticated...

This study assesses the economic implications of China's changing population in the 21st century using a numerical general equilibrium model. The simulations show that lower fertility rates yield lower saving rates. Since lower fertility rates reduce the future supply of labor, capital will...

This paper calculates the levels of optimal national saving, investment, and the current account balance for five Asian economies—Hong Kong SAR, Japan, Singapore, Malaysia, and the Philippines—for the period 1997–2050 using a simulation approach. These calculations show the sensitivity of...

In coming decades, China will undergo a notable demographic transformation, with its old-age dependency ratio doubling to 24 percent by 2030 and rising even more precipitously thereafter. This paper uses the permanent income hypothesis to reassess national savings behavior, with greater...

The paper develops a general equilibrium framework to examine the economic implications of population aging in Japan. Particular attention is paid to aggregate saving behavior which is modeled on the basis of empirical age-earnings profiles using a life-cycle approach. The paper's objectives are...

This paper simulates the macroeconomic effects of population aging in a dynamic overlapping generations model of a small open economy. The model is calibrated to data for the Czech Republic, where population aging is proceeding at a pace comparable to that in other advanced countries in Europe....

This paper quantitatively investigates how population aging trend affects fiscal space measured as unused revenue generating capacity by utilizing a standard neoclassical growth model. A calibration exercise for G-7 countries shows that France, Germany and Italy suffer greater revenue impact...

China is on the eve of a demographic shift that will have profound consequences on its economic and social landscape. Within a few years the working age population will reach a historical peak, and then begin a precipitous decline. This fact, along with anecdotes of rapidly rising migrant wages...

How will the world-wide decline in real interest rates associated with global aging affect small open economies (SOEs) with aging populations? Lower interest rates will result in higher capital-labor ratios and increased wages; higher wages, in turn, will be passed on to pension benefits,...

This paper analyzes various reform options for Japan's public pension in light of large fiscal consolidation needs of the country. The most attractive option is to increase the pension eligibility age in line with high and rising life expectancy. This would have a positive effect on long-run...
