Using an overlapping generations model, two new indicators of public pension system sustainability are proposed: the pension space, which measures the capacity to pay for pension expenditures out of labour taxation, and the pension space exhaustion probability reflecting demographic...

Over the next four decades, increasing old-age dependency ratios exert an enormous upward pressure on welfare spending in most developed countries. As this is mainly due to existing unfunded public pension schemes, many countries have embarked on far-reaching reforms in this area, strengthening...

We study how occupations shape individual and aggregate retirement behavior. First, we document large differences in individual retirement ages across occupations in U.S. data. We then show that retirement behavior among European workers is strongly correlated with U.S. occupational retirement...

Prefunding of pension commitments in OECD economies is increasingly seen as a central strategy to cope with the aging of their populations. This paper argues that investments in emerging markets can help at the margin but are unable to solve the demographic problem. While these investments bring...

We study the sustainability of pension systems using a life-cycle model with distortionary taxation that sets an upper limit to the real value of tax revenues. This limit implies an endogenous threshold dependency ratio, i.e. a point in the cross-section distribution of the population beyond...

This paper studies the transmission mechanism from family culture to economic institutions, by analyzing the impact of the within family organization on the original design of the public pension systems. We build a simple OLG model with families featuring either weak or strong internal ties....

Strong evidence shows that the existing pattern of cross-border pension taxation in OECD countries and beyond is extremely diverse and inconsistent, generating a double fairness dilemma for individuals and countries alike. This paper argues that this dilemma cannot be solved within the current...

In many policy areas it is essential to use the best estimates of life expectancy, but it is vital to most areas of pension policy. This paper presents the conceptual differences between static period and dynamic cohort mortality tables, estimates the differences in life expectancy for Portugal...

This paper analyzes the impact of aging on capital accumulation and welfare in a country with a sizable unfunded social security system. Using a two-period overlapping generation model with potentially endogenous retirement decisions, the paper shows that the type of aging, i.e. declining...

This paper analyzes the impact of demographic aging on capital accumulation and welfare in economies with unfunded pensions. Using a two-period overlapping generation model with potentially endogenous retirement decisions, it shows that both the type of aging, i.e. declining fertility or...
