Effect of mood and worker incentives on workplace productivity
研究情绪对呼叫中心员工生产力的因果影响，发现情绪好反而降低固定薪酬员工的生产力，但绩效薪酬能缓解这一负面效应。
Abstract We study the causal effect of mood on the productivity of call-center workers. Mood is measured through an online “mood questionnaire” which the workers are encouraged to fill out daily. We find that better mood actually decreases worker productivity for workers whose compensation is largely fixed. The negative effect of mood is attenuated for workers whose compensation is based on performance (high-powered incentives). This finding holds both at a correlational level and in two IV settings, where mood is instrumented for by weather or, alternatively, by whether the local professional sports team played/won the day before. We rule out a number of threats to the exclusion restrictions, and discuss the mechanisms that could generate our findings.
