Unemployment Insurance (UI) Benefit Generosity and Labor Supply from 2002 to 2020: Evidence from California UI Records
利用加州20年行政数据和回归扭结设计，研究发现失业保险福利水平对劳动供给的行为效应在2002至2019年间不随商业周期变化，但疫情期间效应显著降低。
This paper obtains comparable estimates of the effect of unemployment insurance (UI) benefits on labor supply throughout the unemployment spell and over the business cycle using a regression kink design and 20 years of administrative data from California. For a given unemployment duration, the behavioral effect of UI benefit levels on labor supply does not vary with the business cycle from 2002 to 2019. However, due to increased coverage from extensions in benefit durations, the duration elasticity of UI benefits rises during recessions. The behavioral effect during the start of the COVID-19 pandemic is substantially lower at all unemployment durations.
