%0 Report %A Mitman, Kurt %A Rabinovich, Stanislav %T Whether, When and How to Extend Unemployment Benefits: Theory and Application to COVID-19 %D 2021 %8 2021 Jan %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 14085 %U https://www.iza.org/index.php/publications/dp14085 %X We investigate the optimal response of unemployment insurance to economic shocks, both with and without commitment. The optimal policy with commitment follows a modified Baily-Chetty formula that accounts for job search responses to future UI benefit changes. As a result, the optimal policy with commitment tends to front-load UI, unlike the optimal discretionary policy. In response to shocks intended to mimic those that induced the COVID-19 recession, we find that a large and transitory increase in UI is optimal; and that a policy rule contingent on the change in unemployment, rather than its level, is a good approximation to the optimal policy. %K unemployment insurance %K unemployment %K optimal policy %K COVID-19
