This paper investigates how demographic change affects the financial sustainability of a defined benefit pay-as-you-go social security system in an environment with collective bargaining on the labor market. Temporary equilibrium analysis shows that the contribution rate decreases, if the...

This study provides a comprehensive analysis of the generational wealth transfer within Sweden's public pay-as-you-go pension system introduced in 1960. Using extensive administrative registers, the paper quantifies the contributions made and benefits received by each birth cohort. The findings...

This paper studies retirement and child support policies in a small, open, overlapping-generations economy with PAYG social security and endogenous retirement and fertility decisions. It demonstrates that neither fertility nor retirement choices necessarily coincide with socially optimal...

Households that postpone claiming Social Security benefits are, in effect, making additional purchases of the Social Security annuity and acquiring valuable longevity insurance. This paper investigates the impact of plausible variations of subjective mortality beliefs on the value of delayed...

The paper shows the effect of demographic change on per capita burden of financing a PAYG social security system in the standard OLG model with frictional labor markets. Rising longevity and decreasing fertility both induce a rise in the employment level via increased capital accumulation and...

Ýmrohoroðlu, Ýmrohoroðlu and Joines [1995, A life-cycle analysis of Social Security, Economic Theory, vol. 6, 83-114] show that the optimal replacement ratio of the payas-you-go public pension system in the US economy amounts to 30%. We extend their analysis to a model that 1) replicates the...

The paper shows the effect of demographic change on per capita burden of financing a PAYG social security system in the standard OLG model with frictional labor markets. Rising longevity and decreasing fertility both induce a rise in the employment level via increased capital accumulation and...

The paper investigates the impacts of demographic change on the financial sustainability of a pay-as-you-go social security system in an economy with unemployment caused by trade unions. Using a simple two-period overlapping generations approach, it can be shown that the trade union behavior...

In this paper, we analyse the effects of demographic change on a PAYG pension system, financed with a defined contribution scheme. In particular we examine the relationship between retirement, fertility and pensions in a three-period overlapping generations model. We focus on both the case of...
