The sustainability of a defined benefit pay-as-you-go (DBPAYG) pension system is investigated in the context of an overlapping-generations model of endogenous fertility with heterogeneous agents. The model places particular emphasis on the time costs of child rearing. It illustrates the...

A two-stage bargaining model is developed to describe how fertility decisions are made in a strategic family setting. Given the assumption that family contracts are incomplete and cannot be used to enforce optimal behavior, it is shown that investments in children (i.e. the fertility rate) may...

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...

It is usually accepted that a pure NDC scheme is not adequate to protect individuals against the risk of poverty in old age, because it does not incorporate any redistribution of the system`s revenue. However, we show that insufficient coverage and weak social protection can be more seriuos...

This paper analyzes and compares the macroeconomic performance of defined-benefit and defined-contribution pay-as-you-go pension systems when population ages. When the fertility rate decreases or longevity rises, it is shown that a shift from defined benefit (defined total benefit or defined...

In economically developed countries, aging of the population with fewer children is progressing. Social security benefits such as pensions and elderly care are increasing. In a society with fewer children, it is difficult for a government to provide sufficient pension benefits for older people...

Some economically developed countries are suffering from an aging society with fewer children, which has brought about greater burdens imposed by social security. A child allowance and child-care services are provided by the governments in these countries to raise fertility. An increase in...

This paper discusses alternative ways to deal with the positive externalities of having children in a pay-as-you-go pension system. Family allowances are compared to introducing a fertility-related component into the pension formula. In an endogenous labor supply setting, both instruments are...

The labor-leisure distortion of a pay-as-you-go pension system can be reduced through a stronger tax-benefit link or Bismarck pension system. Distortions of the fertility decision can be reduced through the introduction of a stronger child-benefit or child pension system.Within our optimal...
