The currently observed demographic change consists of two independent developments that differ in structure and persistence: (1) A slow, monotonic and (presumably) permanent ageing effect caused by an increasing life expectancy; (2) a more rapidly changing, non-monotonic and less permanent...

The currently observed demographic change consists of two independent develop-ments that differ in structure and persistence: (1) A slow, monotonic and (presum-ably) permanent ageing effect caused by an increasing life expectancy; (2) a morerapidly changing, non-monotonic and less permanent...

This paper focuses on alternative money’s worth measures of the Italian (public) pension system for representative cohorts, considering both the present transition and the future steady state envisaged by recent reforms. Micro-based calculations of the aggregate budget effects induced by...

We ask whether a PAYG-financed social security system is welfare improving in an economy with idiosyncratic and aggregate risk. We argue that interactions between the two risks are important for this question. One is a direct interaction in the form of a countercyclical variance of idiosyncratic...

When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations and demonstrate that they interact over the life-cycle. The interactions appear even though...

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...
