中文摘要

本文考察家庭如何调整储蓄和消费支出,以应对预期中的提前退休年龄(ERA)提高。我们研究了德国1999年的养老金改革,该改革将1951年以后出生女性的提前退休年龄至少提高了三年。首先,我们提供了提示性证据,表明女性会根据这项改革调整其退休计划。利用德国收入与消费调查数据,我们发现,该改革使私人储蓄下降了0.6个百分点,这一影响主要由有已婚女性的家庭所驱动。我们还表明,有高学历女性的家庭和拥有住房的家庭更有可能降低储蓄率。此外,我们发现,处理组家庭增加了休闲支出,而可支配收入水平保持不变。我们的研究结果表明,这些家庭预期终身收入将增加,因而通过降低储蓄率来平滑消费。

Abstract

This paper examines how households adjust their savings and consumption expenditure in response to an anticipated increase in the early retirement age (ERA). We examine the 1999 pension reform in Germany, which increased the ERA for women born after 1951 by at least three years. First, we present suggestive evidence that women update their retirement planning in response to the reform. Using the German Income and Consumption Survey, we find a negative impact on private savings of 0.6 percentage points that is driven by households with married women. We show that households consisting of highly educated women and homeowners are more likely to reduce their savings rates. Furthermore, we find that the treated households increase their leisure spending while maintaining an unchanged level of disposable income. Our findings suggest that the households anticipate experiencing a lifetime income increase and reduce their savings rate to smooth consumption.
