In aggregate U.S. data, exogenous shocks to labor productivity induce highly persistent and hump-shaped responses to both the vacancy-unemployment ratio and employment. The authors show that the standard version of the Mortensen-Pissarides matching model fails to replicate this dynamic pattern...

This study provides new evidence on skill requirements in the labor market and shows to what extent skill demand is associated with wages and vacancy duration. Using more than 1.5 million job postings administered by the Austrian public employment service, I identify the most common skill...

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 provides empirical evidence on both the magnitude and determinants of unfilled positions for information technology workers using cross-sectional data on 4150 German firms. Vacancies are defined as unfilled positions excluding those created by replacement needs during the first half...

I study occupational mobility and the effect of unemployment insurance (UI) on mobility using a task-based distance measure between occupations based on O*NET's classification of occupational skill requirements. Using job-to-unemployment-to-job transitions in the US Current Population Survey I...

This paper provides empirical evidence on both the magnitude and determinants of unfilled positions for information technology workers using cross-sectional data on 4150 German firms. Vacancies are defined as unfilled positions excluding those created by replacement needs during the first half...

I provide evidence that decreased efficiency in the appointment process to the Board of Governors of the Federal Reserve has resulted in an increase in the number of average vacancies. I then estimate whether this increase in vacancies is costly for the economy. I find little evidence to suggest...

Two-dimensional transition metal dichalcogenides (TMDCs) nanomaterials have attracted tremendous research interest in various fields, while the effects of eco-corona formation on the transformation mechanisms and ecological risk of TMDCs remain largely unknown. The effect of eco-corona formation...
