The Demand for Hours of Labor: Direct Evidence from California
利用加州1980年将加班费规定扩展至男性的政策变化，分析1973、1985和1991年人口调查数据，发现加班惩罚显著减少了男性加班时长，需求弹性至少为-0.5。
California's longstanding requirement that most women receive time-and-a-half pay for workhours beyond eight in one day was extended to men in 1980. Analyzing Current Population Survey data from 1973, 1985, and 1991, we find that this overtime penalty substantially reduced the amount of daily overtime worked by California men relative to men in other states. Comparisons that use women to control for California-specific shocks show even stronger effects. The estimates imply a price elasticity of demand for overtime hours of at least -0.5. © 2000 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
