The Lock-in Effects of Information on Part-time Unemployment Benefits
在法国对失业者进行大规模随机实验，提供兼职失业补助信息后，发现人们更倾向边领补助边工作，但退出失业的比率下降，形成锁定效应，总支出不变。
<h3>Abstract</h3> We conducted a large randomized controlled experiment that provides information on part-time unemployment benefits to unemployment insurance recipients in France. The information provision had a significant positive impact on the propensity to work while on claim, but reduced the unemployment exit rate, showing important lock-in effects into unemployment associated with part-time unemployment benefits. The extension of the duration of compensated unemployment counterbalanced the increase in the number of days worked while on claim so that the net expenditure of unemployment insurance remained unchanged.
