The Effect of an Increase in Worker's Compensation Benefits on the Duration and Frequency of Benefit Receipt
利用加州行政数据，研究1990年代中期临时伤残福利金增加对受伤工人领取时长和申请频率的影响，发现福利增加延长了领取时长，并可能提高受伤后申请福利的概率。
We present quasi-experimental estimates of the effect of changes in workers' compensation benefits on benefit duration and application frequency, using administrative data for California. Our design exploits two increases in temporary disability benefits occurring during the mid-1990s. We find consistent increases in the duration among injured workers whose benefits were affected by the schedule changes, and some evidence indicating that the likelihood of filing for benefits conditional on being injured is responsive to benefit levels. Finally, we evaluate whether the frequency effect on applying for indemnity benefits introduces a sample selection bias into standard quasi-experimental estimates of duration benefit elasticities. 2004 President and Fellows of Harvard College and the Massachusetts Institute of Technology.
