Temporary Agency Work and Firm Competitiveness: Evidence from German Manufacturing Firms

This paper addresses the relationship between the utilization of temporary agency workers by firms and their competitiveness measured by unit labor costs, using a rich, newly built, dataset of German manufacturing enterprises. We conduct the analysis by applying different panel data models while taking the inherent selection problem into account. Making use of dynamic panel data models allows us to control for firm‐specific fixed effects as well as for potential endogeneity of explanatory variables. The results indicate an inverse U‐shaped relationship between the extent that temporary agency workers are used and the competitiveness of firms.
