Social Security and Households' Saving
利用1992年意大利养老金改革，采用双重差分法估计养老金财富减少对家庭储蓄率的影响，发现储蓄率显著上升，且35-45岁工人的替代性最高。
This paper provides new evidence on the substitutability between private and pension wealth by exploiting the Italian pension reform of 1992. We use a difference-in-difference estimator that exploits the differential effects of the reform on individuals belonging to several year-of-birth cohorts and different occupational groups. We find convincing evidence that saving rates increase as a result of a reduction in pension wealth. By allowing for the possibility that substitutability changes with age, we find that substitutability is particularly high (and precisely estimated) for workers between 35 and 45.
