Abstract: Helping behavior, which is the exertion of effort for one's coworkers, is an important driver of workplace productivity and job satisfaction. We show that differences in leadership, together with employees' social preferences and personality traits, explain firm-level differences in helping behavior in the workplace. Our results are based on matched employer-employee panel data that are representative of larger, private firms in Germany. The data utilize established and behaviorally validated survey items and take into account a rich set of controls both on the employee and firm level. Our results corroborate the importance of both leadership and workforce composition for the manifestation of helpful workplace cultures.
