The impact of demographic change on U. S. labor markets: discussion

I enjoyed reading this paper, particularly so because I was writing a paper on aging and its impacts on the German labor market at the very same time that Jane Little and Robert Triest were developing their paper. Their interesting, broad-based, and thoughtful analysis has a decidedly American point of view. My main duty as a discussant, therefore, is to compare their analysis and their projections with a European perspective.Demography ; Economic conditions ; Labor market

Surface discharge through an insulator in a vacuum

A model for the mechanism of stationary discharges over insulators in a vacuum was developed. Upon introduction of this discharge, the insulator charges as a result of secondary emissions, in such a way that electrons coming from the cathode strike with an average secondary electron yield of 1, and so that the secondary electrons return again to the insulator through the electric field near the insulator. When the secondary electrons strike, electrons with an average yield of 1 are released again. The electrons move in short faults toward the anode, which they strike with lesser energy

Population Aging, Savings Behavior and Capital Markets

Population aging is just beginning to hit the industrialized countries in full force, and it will have a tremendous impact on capital markets. In this paper, we argue that the capital market effects of population aging are particularly strong in continental European economies such as Germany, France, and Italy, with their large and ailing pay-as-you-go public pension systems, relatively thin capital markets, and poor capital performance. The younger generations in these countries are quite aware of the need to provide for more retirement income through own private saving, and these effects will be accentuated by fundamental pension reforms that aim at more pre-funding. Population aging changes households' savings behavior and portfolio composition, and much more assets will be invested on the stock market. Capital markets will grow in size, and active institutional investors such as pension funds will become more important in continental European countries. These changes are likely to have beneficial side effects in terms of improved capital efficiency, total factor productivity, and growth. Looking at the effects of population aging on savings behavior and capital markets therefore adds a new dimension to the continuing debate about advantages and disadvantages of pay-as-you-go and fully funded pension systems.

Demographic Change, Relative Factor Prices, International Capital Flows, and Their Differential Effects on the Welfare of Generations

Demographic change has differential impacts on the welfare of current and future generations. In a simple closed economy, aging -- a relative scarcity of young workers -- increases wages, increasing the welfare of the young. At the same time, population aging will reduce rates of return to capital, thereby reducing the welfare of asset holders who are usually older than the population average. In a global world with pension systems, however, these effects are less straightforward, since international capital flows dampen the factor price changes. Moreover, pay-as-you-go pension systems financed by payroll taxes create a wedge between net and gross wages, and their intergenerational redistribution has important additional effects on the welfare of generations. To quantify these effects, we develop a large-scale multi-country overlapping generations model with uninsurable labor productivity and mortality risk. Due to the predicted relative abundance of the factor capital, the rate of return falls between 2005 and 2050 by roughly 90 basis points. Our simulations indicate that capital flows from rapidly ageing regions to the rest of the world will initially be substantial, but that trends are reversed when households de-cumulate savings. In terms of welfare, our model suggests that young individuals with little assets and currently low labor productivity indeed gain from higher wages associated with population aging. Older, asset-rich households tend to loose because of the predicted decline in real returns to capital.

Disability, Pension Reform and Early Retirement in Germany

The aim of this paper is to describe for (West) Germany the historical relationship between health and disability on the one hand and old-age labor force participation or early retirement on the other hand. We explore how both are linked with various pension reforms. To put the historical developments into context, the paper first describes the most salient features and reforms of the pension system since the 1960s. Then we show how mortality, health and labor force participation of the elderly have changed since the 1970. While mortality (as our main measure of health) has continuously decreased and population health improved, labor force participation has also decreased, which is counterintuitive. We then look at a number of specific pension reforms in the 1970s and 1980s and show that increasing or decreasing the generosity of the pension system has had the expected large effects on old-age labor force participation. Finally, we explore the possible link between early childhood environment and early retirement by analyzing the retirement behavior of cohorts born during World War I, a period of harsh living conditions among the civilian population in Germany. Our data show higher early retirement rates among those cohorts, presumably because those cohorts still suffer from worse health on average many decades after their birth.
