“…Similarly, the significance of productivity spillovers between coworkers within teams has been demonstrated in various economic domains: examples are, among others, Kahane (2000, 2004), Kendall (2003), Franck and Nüesch (2010), and Alvarez et al (2011). Also, several field studies demonstrate the effects of peers on the productivity of workers, see for example Mas and Moretti (2009), Bandiera et al (2010), Chan et al (2014), and most recently Friebel et al (2017), who confirm the presence of significant complementarities between team members, here for the case of a retail chain. 7 Moreover, Herbst and Mas (2015) compare results from laboratory experiments with field studies and conclude that both yield similar estimates of peer effects.…”
