短时工作与预防性储蓄

Short-Time Work and Precautionary Savings

中文摘要

在新冠疫情危机期间,大多数经合组织(OECD)国家采用短时工作制度(对缩减工时给予补贴)来维持就业。本文表明,短时工作会影响企业(供给侧)和家庭(需求侧)的行为。首先,利用德国的家庭调查数据,我们发现短时工作带来的消费风险低于失业。其次,我们构建了一个包含异质性工人和企业、不完全资产市场以及劳动力市场摩擦的新凯恩斯模型。短时工作削弱了工人的预防性储蓄动机,并降低了劳动力成本。这在降低离职率和失业率的水平及波动性的同时,也使工人被束缚在生产率较低的企业中。从定量结果看,正向的就业效应超过了生产率损失。

Abstract

During the Covid-19 crisis, most OECD countries used short-time work (subsidised reductions in working hours) to preserve employment. This paper documents that short-time work affects the behaviour of firms (supply) and households (demand). First, using household survey data from Germany, we show that the consumption risk of short-time work is lower than that of unemployment. Second, we construct a New Keynesian model with heterogeneous workers and firms, incomplete asset markets, and labour market frictions. Short-time work weakens workers’ precautionary savings motive and lowers labour costs. This reduces the level and volatility of both the separation and unemployment rate at the cost of tying workers to less productive firms. Quantitatively, the positive employment effects dominate the productivity losses.
