我们将健康和长寿添加到生命周期储蓄的标准模型中，并表明，在合理的假设下，预期寿命的增加会导致每个年龄段的储蓄率更高，即使退休是内生的。在固定的人口中，这些较高的储蓄率被老年依赖性的增加所抵消，但在不平衡阶段，当寿命延长时，对总储蓄率的影响可能是巨大的。我们发现实证支持这一效应使用跨国面板的国民储蓄率。
We add health and longevity to a standard model of life-cycle saving and show that, under plausible assumptions, increases in life expectancy lead to higher savings rates at every age, even when retirement is endogenous. In a stationary population these higher savings rates are offset by increased old age dependency, but during the disequilibriurn phase, when longevity is rising, the effect on aggregate savings rates can be substantial. We find empirical support for this effect using a cross-country panel of national savings rates.
