RT Journal Article T1 The labour market returns to sleep. A1 Costa-Font, Joan A1 Fleche, Sarah A1 Pagán-Rodríguez, Ricardo Braulio K1 Mercado de trabajo - Aspectos sociales AB Despite the growing prevalence of insufficient sleep among individuals, we still know little aboutthe labour market return to sleep. To address this gap, we use longitudinal data from Germanyand leverage exogenous fluctuations in sleep duration caused by variations in time and localsunset times. Our findings reveal that a one-hour increase in weekly sleep is associated with a1.6 percentage point rise in employment and a 3.4% increase in weekly earnings. Such effecton earnings stems from productivity improvements given that the number of working hoursdecreases with longer sleep duration. We also identify a key mechanism driving these effects,namely the enhanced mental well-being experienced by individuals who sleep longer hours.
