We study peer effects in absenteeism among workplace colleagues. Gatekeeping is an essential task in many insurance systems. In this study we exploit exogenous shifts of general practitioners (GPs) occurring when physicians quit or retire. We find that these shifts induce changes in absenteeism for affected workers. By utilizing high-quality Norwegian matched employer-employee data with detailed individual information on certified sick leave during the period 2003–2012, we can study how the transfer of workers between GPs affects co-workers’ absenteeism. We identify strong causal positive peer effects in absenteeism: a one day change in focal worker sickness absence transfers to a 0.41?day shift in peer absence.
