Individual and Aggregate Labor Supply with Coordinated Working Times
分析了两种扩展的生命周期劳动供给模型，一种假设个人面临连续工资-工作时间选择，另一种假设工作时间需协调。两种模型对税收政策的总体劳动供给反应有不同含义，后者中休闲效用函数的曲率至关重要。
I analyze two extensions to the standard model of life‐cycle labor supply that feature operative choices along both the intensive and extensive margin. One assumes that individuals face continuous wage‐hours schedules, while the other assumes that all work must be coordinated across individuals. Though similar qualitatively, the two models have very different implications for aggregate labor supply responses to tax policy. In the first model, curvature in the individual utility from leisure function plays relatively little role, but in the second model, it is of first‐order importance. The second model also has important implications for what data are best able to provide evidence on the extent of curvature in the utility from leisure function.
