Working Long Hours and Early Career Outcomes in the High-End Labor Market
研究发现每周工作时间与小时工资增长呈正相关但非线性关系，每周超过47小时后每增加5小时年工资增长提高1%，这一关系对年轻专业人士尤为显著，并可用于解释部分性别工资差距。
This study establishes empirically a positive but nonlinear relationship between weekly hours and hourly wage growth. For workers who put in over 47 hours per week, 5 extra hours are associated with a 1% increase in annual wage growth. This correlation is not present when hours are lower. The relationship is especially strong for young professionals. Data on promotions provide evidence in support of a job-ladder model that combines higher skill sensitivity of output in higher-level jobs with heterogeneous preferences for leisure. The results can be used to account for part of the gender wage gap.
