In many countries the fiscal tension associated with the global financial crisis brings about the discussion about unprivatizing the social security system. This paper employs an OLG model to assess ex ante the effects of such changes to the pension reform in Poland from 1999 as implemented in...

Pension system reforms involve fiscal consequences. In practice, a variety of fiscal closures may be implemented, while not all of them involve the same extent of distortions. This paper develops an overlapping generations model to analyze the case of a shift from pay-as-you-go defined benefit...

The objective of this paper is to analyze the welfare effects of raising the retirement age. With aging populations, in many countries de iure retirement age has been raised. With a standard assumption that individuals prefer leisure to work, such policy necessitates some welfare deterioration....

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...

Has the crisis indeed demonstrated that as profession we are misled by the beauty of the mathematical models and the only useful, workable solutions at hand were provided in early 1930s? The objective of this paper is to provide a review of the current state-of-the-art literature from the...

Many countries consider rising fertility through pro-family policies as a solution to the fiscal pressure stemming from longevity. However, an increased number of births implies immediate private costs and only delayed public benefits of younger and larger population. We propose using an...

We develop an OLG model with realistic assumptions about longevity to analyze the welfare effects of raising the retirement age. We look at a scenario where an economy has a pay-as-you-go defined benefit scheme and compare it to a scenario with defined contribution schemes (funded or notional)....

We analyze the political stability of funded social security. Using a stylized theoretical framework we study the mechanisms behind governments capturing social security assets in order to lower current taxes. The results and the driving mechanisms carry over to a fully-fledged and carefully...
