Increasing longevity causes an upward trend in the dependency ratio in many countries. This raises concerns about the financial sustainability of social security schemes, and reform initiatives and proposals abound. It is shown that a fundamental policy choice inevitably arises since a given...

The Croatian system of old-age provision comprises a traditional public pay-as-you-go scheme and a mandatory funded scheme (“second pillar”) that will provide increasing amounts of supplementary pensions to those entering retirement in the future. Due to the continuing economic crisis, the...

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...

Aging creates financial troubles for PAYG pension systems, since the share of retirees to workers increases. An often advocated policy response is to increase retirement age. Ironically, however, the political support for this policy may actually be hindered by population aging. Using Swiss...

Fertility has long been declining in industrialised countries and the existence of public pension systems is considered as one of the causes. This paper is the first to provide detailed evidence based on historical data on the mechanism by which a public pension system depresses fertility. Our...

The role of inherited wealth in modern economies has increasingly become under scrutiny. This study presents one of the first attempts to shed light on how demographic aging could shape this role. We show that, in the absence of retirement annuities, or for a given level of annuitization, both...

The pay-as-you-go social security system, which suffers from dwindling labor force, can benefit from immigrants with birth rates that exceed the native-born birth rates in the host country. Thus, a social security system provides effectively an incentive to liberalize migration policy. The paper...

We study the effects of demographic shocks and changes in the pension system on the macroeconomic performance of an advanced small open economy. An overlapping-generations model is constructed which includes a realistic description of the mortality process. Individual agents choose their optimal...

Public pay-as-you-go pensions still form the dominant pillar of old-age provision in Germany. This is in marked contrast to the situation in Anglo-Saxon countries. It has advantages if labour markets are strong, e.g., following a quick recovery from the Great Recession. It has disadvantages, as...

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