Ageing and retirement age. What can we learn from the Overlapping Generations Model ?

In this paper, the two-period OLG model has been modified to distinguish the effects of individual ageing from changes in the birth rate. Optimal pension and retirement age policies have been characterized in a dynamic framework. We have considered a mixed pension scheme that is fully funded, but offers agents an actuarially fair choice on their retirement age. We show that this mixed pension scheme makes it possible to implement the optimal solution. The numerical simulations describe the dilemmas France currently faces.
