Private pension provision faces the challenging task of providing stable income streams during retirement. The challenge has increased markedly in the last decades due to volatile financial markets, falling interest rates and the withdrawal of employers and external insurers as risk bearers of...

This paper examines how labor income volatility and social security benefits can influence lifecycle household portfolios. We examine how much the individual optimally saves and where, taking into account liquid financial wealth and annuities, and stocks as well as bonds. Higher labor income...

This Paper uses stochastic simulations on calibrated models to assess the steady state impact of different pension arrangements in an environment where financial markets are less than perfect. Surprisingly little is known about the optimal split between funded and unfunded systems when there are...

This paper derives optimal life cycle portfolio asset allocations as well as annuity purchases trajectories for a consumer who can select her hours of work and also her retirement age. Using a realistically-calibrated model with stochastic mortality and uncertain labor income, we extend the...

This paper uses stochastic simulations on calibrated models to assess the optimal degree of reliance on funded pensions and on a particular type of unfunded (PAYG) pension. Surprisingly little is known about the optimal split between funded and unfunded systems when there are sources of...

China’s population is set to age fast, owing to low fertility and rising life expectancy. With ongoing migration of the younger cohorts to urban areas the increase in the old-age dependency ratio will be even more pronounced in rural than in urban areas. Very different pension arrangements...

If considered within the context of an overlapping-generations framework, pay-as-you-go pension systems turn out to be funded by the human capital embodied in subsequent generations. The failure to actually model public old-age security on this idea may, to a large degree, explain the current...

This paper analyses the effects of rumours and changes in life expectancy in an economywith endogenous fertility and pay-as-you-go (PAYG) pensions. We show that the endogeneity of fertility makes society vulnerable to both pessimistic beliefs and an increasing life span. On the one hand, rumours...

China’s population is set to age fast, owing to low fertility and rising life expectancy. With ongoing migration of the younger cohorts to urban areas the increase in the old-age dependency ratio will be even more pronounced in rural than in urban areas. Very different pension arrangements...

In this Paper, we study the role of subsidies to fertility in ensuring the political viability of unfunded social security (SS). In our model, agents are heterogeneous in age and income. Young generations confront promises made previously by older generations, and in turn choose current levels...
