Peter Nilsson's paper with Jonas Kolsrud, Camille Landais, and Johannes Spinnewijn, "The Optimal Timing of Unemployment Benefits: Theory and Evidence from Sweden"  has been accepted for publication in the American Economic Review.

This paper provides a simple, yet robust framework to evaluate the time profile of benefits paid during an unemployment spell. We derive sufficient-statistics formulae capturing the marginal insurance value and incentive costs of unemployment benefits paid at different times during a spell. Our approach allows us to revisit separate arguments for inclining or declining profiles put forward in the theoretical literature and to identify welfare-improving changes in the benefit profile that account for all relevant arguments jointly. For the empirical implementation, we use administrative data on unemployment, linked to data on consumption, income and wealth in Sweden. First, we exploit duration-dependent kinks in the replacement rate and find that, if anything, the moral hazard cost of benefits is larger when paid earlier in the spell. Second, we find that the drop in consumption affecting the insurance value of benefits is large from the start of the spell, but further increases throughout the spell. In trading of insurance and incentives, our analysis suggests that the at benefit profile in Sweden has been too generous overall. However, both from the insurance and the incentives side, we find no evidence to support the recent introduction of a declining tilt in the profile.​
