The study reported in this document is part of a larger research effort by the Employment and Training Administration to examine recruitment and hiring processes. This study presents a comparison of stocks and flows of occupational listings in help wanted ads and listings placed with the public employment service (ES) by local employers. Comparisons are made at the end of each of twelve months in twelve labor market areas (Atlanta, Boise, Dayton, etc.). Employers using one or the other or both medium(s) are identified. Volume comparisons are made for occupational and industrial makeup and between geographic areas. Analysis is made of the impact of low-pay, low-status occupations on intermediaries, and the effect of mandatory listings on the ES. Findings include twenty-three highlights: (1) on first encounter, the ES and want ads have approximately the same listings volume of jobs available to job seekers; (2) a daily visit to ES exposes job seekers to 1.2 additional jobs during remaining monthly work days; (3) want ads receive almost three times more new listings than ES in twenty-eight days, and higher volume in all occupations; etc. The findings are thought to be germane to considerations of amending the Wagner-Peyser Act.
