Abstract This study explores the linkage between the labor force participation of the elderly and the long-run performance of the economy in the context of a two-period-lived overlapping generations model. We assume that the old agents are heterogeneous in their labor efficiency and they continue working if their income exceeds the pension that can be received in the case of full retirement. We first inspect the key factors that determine the retirement decision of the elderly. We then examine analytically as well as numerically the long-run impact of labor participation of the elderly on capital accumulation and income distribution.

Today most countries are experiencing fast population aging, which is going to last the entire 21st century. Its economic effects are multifarious and will in large part shape further dynamics of the global economy not only in the short or medium but also in the long run. Unfortunately, Russian economists and politicians are hardly aware of how diverse economic consequences of population aging are since their attention is focused on its narrow, purely pragmatic, dimensions (such as the raising of pension age, the deficit of the Russian Pension Fund etc.). The paper provides a broad overview of major economic effects of population aging from both theoretical and empirical perspectives. It examines the place of aging in the process of demographic transition, and forecasts its expected trends in subsequent decades for a few countries including Russia. Next, it critically reviews different versions of dependency/support ratios: demographic and economic; chronological and prospective; non-adjusted and adjusted for differences by age in labor income and per capita consumption. Special attention is paid to a basic scheme of relationships between key demographic and macroeconomic variables that highlights how population aging might affect employment, labor productivity, capital intensity, wages, returns to capital, investment and savings. Some additional effects are also analyzed, such as prospective changes in labor supply, human capital accumulation, technological change, real interest, and inflation. A general conclusion is that population aging is not per se a fundamental economic challenge that should endanger society’s welfare. Real dangers arise from existing institutions providing support for the elderly, which were established in the early to mid 20th century under completely different demographic and economic conditions.

AbstractWe study the short-, medium-, and long-run implications of stimulating annuity markets in a dynamic general-equilibrium overlapping-generations model. We find that beneficial partial-equilibrium effects of stimulating annuity markets are counteracted by negative general-equilibrium repercussions. Balancing the positive partial-equilibrium and negative general-equilibrium forces we show that there exists an intermediate level of annuitization such that the lifetime utility of steady-state agents is maximized. Studying the transition to this optimal degree of annuitization shows that currently middle-aged individuals stand to gain most from the stimulation of annuity markets. Complementing our main analysis, we highlight the centrality of the interplay between human-capital accumulation and annuity market policy.

We study the microeconomic and macroeconomic effects of longevity insurance. Using a tractable discrete-time overlapping-generations model of a closed economy we first study different types of government redistribution of accidental bequests in general equilibrium. Individuals face longevity risk, as there is a positive probability of passing away before the retirement period. We find nonpathological cases where it is better for long-run welfare to waste accidental bequests than to give them to the elderly. Next we study the introduction of a perfectly competitive life insurance market offering actuarially fair annuities. There exists a tragedy of annuitization: although full annuitization of assets is privately optimal, it is not socially beneficial, because of adverse general equilibrium repercussions.

In a two-period overlapping-generations model with production, we consider the damaging impact of environmental degradation on health and consequently life expectancy. Despite the presence of social constant returns to capital, which would otherwise generate unbounded growth, when pollution is left unabated, the economy cannot achieve such a path. Instead, it converges either to a stationary level of capital per worker or to a cycle in which capital per worker oscillates permanently. The government's involvement in environmental preservation proves crucial for both short-term dynamics and long-term prospects of the economy. Particularly, an active policy of pollution abatement emerges as an important engine of long-run economic growth. Furthermore, by eliminating the occurrence of limit cycles, pollution abatement is also a powerful source of stabilization.

The purpose of this article is to empirically find the Environmental Kuznets Curve (EKC) relationship between income and carbon dioxide (CO2) emissions and to analyze the influence of population aging on such emissions. We utilize Korean regional panel data of 16 provinces during the period from 1998 to 2016. To account for the nonstationary time series in the panel, we employ a fully modified ordinary least squares (FMOLS) and estimate long-run elasticity. From the empirical results, we can find the nonlinear relationship between income and CO2 emissions. Additionally, we verify the fact that population aging reduces CO2 emissions. A 1% increase in the proportion of the elderly results in a 0.4% decrease in CO2 emissions. On the other hand, the younger population increases CO2 emissions. These results were in line with those of additional analysis on residential and transportation CO2 emissions, for the robustness check.

Population aging, along with a secular decline in real interest rates, is an empirical regularity observed in developed countries over the last few decades. Under the premise that population aging will deepen in coming years, some studies predict that real interest rates will continue to be depressed further to a level below zero. In this paper, we address this issue and explore how changes in demographic structures have affected and will affect real interest rates, using an overlapping generations model calibrated to Japan’s economy. We find that the demographic changes over the last 50 years reduced the real interest rate. About 270 out of the 640 basis points decline in real interest rates during this period was due to declining labor inputs and higher saving, which themselves stemmed from the lower fertility rate and increased life expectancy. As for the next 50 years, we find that demographic changes alone will not substantially increase or decrease the real interest rate from the current level. These changes reflect the fact that the size of demographic changes in years ahead will be minimal, but that downward pressure arising from the past demographic changes will continue to bite. As Japan is not unique in terms of this broad picture of changes in demographic landscapes in the last and next 50 years, our results suggest that, sooner or later, a demography-induced decline in real interest rates may be contained in other developed countries as well.

This paper models growth via on-the-job learning when firms and workers are heterogeneous. It is an overlapping generations model in which young agents match with the old. More efficient assignments lead to faster long-run growth, more inequality, and less turnover in the distribution of human capital. Constant-growth paths are characterized for general functional forms and then, for the Cobb-Douglas case, the transition dynamics are solved analytically when the skill of the young is log-normally distributed and the initial human capital of the old generation is also log-normal. Growth and inequality move together on the transition to the balanced growth path. ( JEL D83, J24, J31, J41)

We assess the long-run growth effects of automation in the overlapping generations framework. Although automation implies constant returns to capital and, thus, an AK production side of the economy, positive long-run growth does not emerge. The reason is that automation suppresses wage income, which is the only source of investment in the overlapping generations model. Our result stands in sharp contrast to the representative agent setting with automation, where sustained long-run growth is possible even without technological progress. Our analysis therefore provides a cautionary tale that the underlying modeling structure of saving/investment decisions matters for the derived economic impact of automation. In addition, we show that a robot tax has the potential to raise per capita output and welfare at the steady state. However, it cannot induce a takeoff toward positive long-run growth.
