Do Online Job Postings Capture Job Vacancies?
Working Paper 35697
DOI 10.3386/w35697
Issue Date
We ask whether online job postings capture U.S. job vacancies, matching near-universal Burning Glass (BG) postings to the representative Job Openings and Labor Turnover Survey (JOLTS). BG converged toward JOLTS over 2007–2022, and its representativeness varies across establishment characteristics. We reweight BG to align postings with JOLTS openings along observables, and assess impacts on prior BG findings. Because large establishments account for most openings and are well represented, the level and cyclicality of skill demand survive our adjustment. But BG overstates labor market concentration (the Herfindahl-Hirschman Index) nearly threefold, because small and mid-sized establishments post less online.
