Employers' search and the efficiency of matching

"Unskilled workers in low productivity jobs typically experience higher labour turnover. This paper shows how this empirical finding is related to variation in the efficiency of the matching process across occupations. A simple theoretical model of employers' search shows that firms find it optimal to invest relatively little in advertisement and screening when recruiting for low productivity jobs. This generates more separations and higher turnover at the bottom than at the top of the jobs' distribution.
