Labour Supply and Saving Under Uncertainty
用一个两期模型分析劳动供给如何作为应对工资不确定性的自我保险工具，发现劳动灵活性会提高预防性储蓄，而工资不确定性则增加当前劳动供给、减少未来劳动供给。
This article examines how variations in labour supply can be used to self-insure against wage uncertainty and the impact of such self-insurance on precautionary saving. The analytical framework is a two-period model with saving and labour-supply decisions, where preferences are consistent with balanced growth. The main findings are that (i) labour-supply flexibility raises precautionary saving when future wages are uncertain, and (ii) uncertainty about future wages raises current labour supply and reduces future labour supply.
