We analyze the political stability of capital funded social security. In particular, using a stylized theoretical framework we study the mechanisms behind governments capturing pension assets in order to lower current taxes. This is followed by an analysis of the analogous mechanisms in a...

We analyze the effects of increasing the retirement age in two economies with overlapping generations and within cohort ex ante heterogeneity. The first economy has a defined benefit system, and the second economy is in transition from a defined benefit to a defined contribution. We find that if...

We analyze the consumption and wealth inequality in an OLG model with mandatory pension systems. Our framework features within cohort heterogeneity of endowments and heterogeneity of preferences. We allow for population aging and gradual decline in TFP growth. We show four main results. First,...

We propose a unified framework to measure the effects of different reforms of the pension system on retirement ages and macroeconomic indicators in the face of demographic change. A rich overlapping generations (OLG) model is built and endogenous retirement decisions are explicitly modeled...

When the challenges of population aging are being debated, the uncertain future of pension systems is a topic of high priority and large controversy. The aim of this chapter is not to provide a “consensus view” on social security and public insurance in aging populations but to put structure...

This chapter provides a review of some implications of demographic shift arising from population aging for fiscal policy, taxation policy, and social security settings. The key implications of population aging that have been forthcoming from the many national and international macroeconomic...

This study analyzes the sustainability implications of demographic and investment risks in the Finnish private sector pension system (TyEL). The results show that current contribution rate is likely to be too low to finance the future higher expenditure. The main sustainability problem is not,...

For decades, pension systems were based on the rising revenue generated by an expanding population (demographic dividend). As changes in fertility and longevity created new population structures, however, the dividend disappeared, but pension systems failed to adapt. They are kept solvent by...
