The Effects of Sleep on Labor Productivity PY - 2025/Jan/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 17618 UR - https://www.iza.org/publications/dp17618 AB - We estimate the effect of sleep on labor productivity addressing the two main challenges in time use research: the unavoidable substitutions among activities implied by the time budget constraint and the endogeneity of the allocation of time. We use complete time diary data to identify the relative effect of sleep vs. non-work activities among employees working the same number of hours, and account for the endogeneity of time use choices by leveraging longitudinal information on productivity in a value-added specification. We show that, when work hours are held constant, substituting sleep with other non-work activities does not affect labor productivity. KW - sleep KW - time use KW - productivity ER -
