Deutschland - Nebenjobberland



"Since 2003, the number and ratio of multiple jobholders has more than doubled, even though the German labour market has been experiencing a strong and sustained upswing. This study analyses multiple jobholding from a time-series as well as a cross-section perspective. We use rich register data and logit estimations. The microeconometric findings are linked to macroeconomic trends. Workers hold multiple jobs primarily because of factors affecting earnings or hours in the main job. Towards the upper end of the earnings distribution, there is no renewed increase in the probability of taking on a secondary job and we do not find evidence that another job enriches the job portfolio as such. Moreover, female workers, migrants, workers in west Germany as well as in service sectors display a higher than average probability of multiple jobholding. However, the individual factors only partly explain the rise of multiple jobholding in the examined time frame. Hence, we argue that the far-reaching exemption of second marginal jobs from social security contributions and taxes sets the wrong incentives." (Author's abstract, IAB-Doku) ((en))
