RT Journal Article SR Electronic T1 The Lock-in Effects of Information on Part-time Unemployment Benefits JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0522-12328R2 DO 10.3368/jhr.0522-12328R2 A1 Benghalem, Hélène A1 Cahuc, Pierre A1 Villedieu, Pierre YR 2023 UL http://jhr.uwpress.org/content/early/2023/10/02/jhr.0522-12328R2.abstract AB 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.
