Abstract

Aging is an important challenge for pension schemes, especially for social security plans mainly 􏰂nanced by PAYG (Pay as you go) and based on a DB formula (De􏰂ned Bene􏰂t). In particular, demographic risks induce important increases of the contributions and threaten the 􏰂nancial sustainability of such schemes. On the other hand, switching to De􏰂ned Contribution plans can be a solution in terms of funding but introduce signi􏰂cant risks in terms of social adequacy. The purpose of this paper is to study hybrid solutions between DB and DC in a stochastic environment. In particular, we simulate for various risk sharing strategies, the evolution of contributions and bene􏰂ts by introducing risk factors in􏰃uencing the demographic dependence ratio (fertility, longevity, baby boom). We study the mean evolution of these processes as well as their value at risk.
