The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
This paper proposes and solves a search model in which job separation requires mandatory notice. When jobs are subject to idiosyncratic uncertainty, firms would issue advance notice even with good business conditions. We show that such precautionary policy is not pursued if it entails sufficiently high productivity losses. If workers can search on the job, an increase in advance notice increases job to job movements, reduces unemployment flows, and has ambiguous effects on unemployment. Results are consistent with the fact that North American and European labor markets, despite their differences in job security provisions, experience similar turnover rates and dissimilar unemployment flows.
