Job Matching on Connected Regional and Occupational Labor Markets [2019: Regional Studies; earlier version 2017: IAB DP]
with Franziska Lottmann and Michael Stops
Abstract: Job mobility equilibrates disparities in local labour markets and influences the job-matching efficiency. We specify a matching function with regional, occupational and combined regional–occupational spillovers of unemployed and vacancies. To construct these spillovers, we use information on regional proximities and occupational similarities. Based on novel German data on new hires, the unemployed and vacancies, we find significant positive effects of all spillover terms, with the exception of the negative and significant spillovers of the unemployed in other occupations. The reverse spillover effects could be used for designing macro-oriented policies aiming to improve job matching.
Changes in Occupational Tasks and Their Association with Individual Wages and Occupational Mobility [German Economic Review; earlier version 2011: SFB 649 DP]
Abstract: This study provides novel evidence on the relevance of task content changes between and within occupations to wage dynamics of occupational changers and stayers. I use individual-level, cross-sectional data featuring tasks performed on the job to compute a measure of proximity of job contents. Then, I merge this measure to a large-scale panel survey to show that occupational changers experience a wage growth that is declining when the accompanying alterations in task contents are big. For occupational stayers, alterations in task contents generate a positive wage component, beyond tenure effect. However, the results are not robust with respect to the choice of proximity measure and over time.
