Performance pay, work hours and employee health in the UK
研究发现英国绩效薪酬与更长工作时间和更差自评健康相关，但约三分之二的工时差异源于员工自选择而非行为改变，且控制工时后健康关联仍存。
A large body of research links performance pay to poorer worker health. The mechanism generating this link remains in doubt. We examine a common suspect, that performance pay causes employees to work longer hours in pursuit of higher pay. Using UK data, we demonstrate that performance pay is associated with more work hours and a higher probability of working long hours. Yet approximately two thirds of these differences reflect worker sorting rather than behavioral change. The remaining effects are small except those for labourers. Indeed, controlling for hours of work does not diminish the link between worse self-reported health and performance pay.
