While confounding factors typically jeopardise the possibility of using observational data to measure peer effects, field experiments offer the possibility of obtaining clean evidence. In this Paper we measure the output of four randomly selected groups of individuals who were asked to fill...

The prevalence of shirking within a large Italian bank appears to be characterized by significant regional differentials. In particular, absenteeism and misconduct episodes are substantially more prevalent in the south. We consider a number of potential explanations for this fact: different...
