本文在一个生育率内生的封闭经济世代重叠模型中分析了公共养老金、生育率和儿童保育之间的关系。它表明，提高一个孩子涉及两个社会外部性，它是最优的，如果政府将收入从年轻人到老年人再分配，引入儿童津贴。当寿命增加时，最佳儿童津贴也会增加。如果抚养孩子的成本与工资成正比，那么第三种外部性就会出现，储蓄的回报应该被征税。
This paper analyses the relation between public pensions, fertility and child care in a closed-economy overlapping generations model with endogenous fertility. It is shown that raising a child involves two social externalities and that it is optimal to introduce child allowances if the government redistributes income from the young to the old. The optimal child allowance rises when longevity increases. If the costs of raising children depend positively on the wage, a third externality arises and the returns to savings should be taxed.
