In this paper I present some evidence on the magnitudes and determinants of job vacancy rates at the firm level. The data are from a survey of firms in 1980 and 1982, as well as from 1980 Census data on industry and local area characteristics. The results show that overall job vacancy rates are...

In this paper we use detailed job vacancy data to estimate changes in skill demand in the years since the Great Recession. The share of job vacancies requiring a bachelor's degree increased by more than 60 percent between 2007 and 2019, with faster growth in professional occupations and...

This paper explores the relationship between the duration of a vacancy and the starting wage of a new job, using unusually informative data comprising detailed information on vacancies, the establishments posting the vacancies and the workers eventually filling the vacancies. We find that...

We use job vacancy data collected in real time by Burning Glass Technologies, as well as unemployment insurance (UI) initial claims and the more traditional Bureau of Labor Statistics (BLS) employment data to study the impact of COVID-19 on the labor market. Our job vacancy data allow us to...

In spring 2005, Austria launched a campaign to inform employers and newspapers that gender preferences in job advertisements were illegal. At the time over 40% of openings on the nation's largest job-board specified a preferred gender. Over the next year the fraction fell to under 5%. We merge...

This paper is the first to study vacancies, hires, and vacancy yields at the establishment level in the Job Openings and Labor Turnover Survey, a large sample of U.S. employers. To interpret the data, we develop a simple model that identifies the flow of new vacancies and the job-filling rate...

This paper studies hours, employment, vacancies and unemployment at micro and macro levels. It is built around a set of facts concerning the variability of unemployment and vacancies in the aggregate and, at the establishment level, the distribution of net employment growth and the comovement of...

Shimer (2005a) argues that the Mortensen-Pissarides equilibrium search model of unemployment explains only about 10% of the response in the job-finding rate to an aggregate productivity shock. Some of the recent papers inspired by his critique are reviewed and commented on here. Specifically, we...

We develop a framework where mismatch between vacancies and job seekers across sectors translates into higher unemployment by lowering the aggregate job-finding rate. We use this framework to measure the contribution of mismatch to the recent rise in U.S. unemployment by exploiting two sources...

We set-up a real business cycle model with search and matching frictions driven by several shocks, which nests full Nash Bargaining and wage rigidity as special cases and includes other transmission mechanisms suggested by the literature for the propagation and amplification of disturbances. The...
