Social Interaction and Sickness Absence

Abstract

Does the average level of sickness absence in a neighborhood affect individual sickness absence through social interaction on the neighborhood level? To answer this question, we consider evidence of local benefit-dependency cultures. Well-known methodological problems in this type of analysis include avoiding the so-called reflection problem and disentangling the causal effects of group behavior on individual behavior from the effects of individual sorting on neighborhoods. Based on data from Sweden, we adopt several different approaches to deal with these problems. The results are robust in the sense that regardless of approach and identifying assumptions, we obtain statistically significant estimates indicating group effects.
