Declining Labor Turnover and Turbulence

The purpose of this paper is to identify possible sources of the secular decline in the job separation rate over the past four decades. I use a simple labor matching model with two types of workers, experienced and inexperienced, where the former type faces a risk of skill loss during unemployment. When the skill loss occurs, the worker is required to restart his career and thus suffers a drop in his wage. I show that a higher risk of skill loss results in a lower separation rate. The key mechanism is that the experienced workers accept lower wages in exchange for keeping their jobs
