Temporary Help Agencies and Occupational Mobility*

This paper analyses the effects of Temporary Help Agencies (THA) on occupational mobility by performing an empirical comparison of the job‐to‐job upgrading chances of agency and regular (non‐agency) workers in Spain. We estimate a switching regression model to allow for self‐selection into agency work because of, for instance, more motivated workers being more likely to search for jobs through a THA. We find evidence in favour of the existence of self‐selection in all qualification groups considered. Concerning mobility, we find that agency workers in intermediate qualification levels are less likely to experience demotions than regular workers. THA increase the probability of high‐skilled workers achieving a permanent contract in Spain.
