Population ageing and the international capital market

Abstract This paper analyses the effects of ageing on the international capital market. The first part applies a simple model and distinguishes between the cases of a small open economy and a closed economy to explore the separate effects of ageing, the design of pension schemes and government policy on savings, labour supply and the interest rate. The second part of the paper analyses cross-border capital flows and spillover effects caused by international differences in ageing patterns, pension schemes and policy reactions. The final part is devoted to the quantitative effects found by various recent simulation studies

Retirement Flexibility and Portfolio Choice in General Equilibrium

This paper explores the interaction between retirement flexibility and portfolio choice in an overlapping-generations model of a closed economy. Retirement flexibility is often seen as a hedge against capital market risks which justifies more risky asset portfolios. We show, however, that this positive relationship between risk taking and retirement flexibility is weakened - and under some conditions even turned around - if not only capital market risks but also productivity risks are considered. Productivity risk in combination with a high elasticity of substitution between consumption and leisure creates a positive correlation between asset returns and labour income, reducing the willingness of consumers to bear risk. Moreover, it turns out that general equilibrium effects can either increase or decrease the equity exposure, depending on the degree of substitutability between consumption and leisure

Flexible Pension Take-up in Social Security

This paper studies the redistribution and welfare effects of increasing the flexibility of individual pension take-up. We use an overlapping-generations model with Beveridgean pay-as-you-go pensions, where individuals differ in ability and life span. We find that introducing flexible pension take-up can induce a Pareto improvement when the initial pension scheme contains within-cohort redistribution and induces early retirement. Such a Pareto-improving reform entails the application of uniform actuarial adjustment of pension entitlements based on average life expectancy. Introducing actuarial non-neutrality that stimulates later retirement further improves such a flexibility reform

Public investment and intergenerational distribution

We study the effects of public investment in a dynamic overlapping-generations model of a small open economy. Boosting public investment stimulates private capital formation, output, and wages in the long run. The impact effects depend critically on whether public capital is modelled as a stock or as a flow. The welfare benefits are unevenly distributed across generations because capital ownership rises with age and wages rise only gradually (under the stock interpretation). A suitable egalitarian bond policy ensures that everybody gains to the same extent. A simple modified golden rule for public investment is derived. (C) 2002 Elsevier Science B.V. All rights reserved
