Working Papers

  • The Optimal Timing of Unemployment Benefits: Theory and Evidence from Sweden - Slides // Draft Coming Soon - (with Jonas Kolsrud, Camille Landais and Peter Nilsson)

    Abstract: This paper provides a general framework to analyze the optimal time profile of benefits during the unemployment spell. We derive simple sufficient-statistics formula capturing the insurance value and incentive costs of unemployment benefits at different times during unemployment. Our general approach allows to evaluate the separate arguments for increasing or decreasing profiles put forward in the theoretical literature. Using administrative data in Sweden on unemployment, income and wealth, we find that the insurance value is fairly constant over the unemployment spell. From the start of the spell savings and credit play only a limited role in smoothing the loss of earnings. We also exploit duration-dependent kinks in the replacement rate and find that the welfare-relevant unemployment elasticity is twice as high for benefits in the first 20 weeks of the spell compared to benefits given after 20 weeks. Our evidence therefore indicates that the recent change from a flat to a declining benefit profile in Sweden has decreased welfare. The local welfare gains push towards an increasing rather than decreasing benefit profile over the spell.

  • Heterogeneity, Demand for Insurance and Adverse Selection - REVISED - (Web Appendix)

    Abstract: Recent empirical work finds that surprisingly little variation in the demand for insurance is explained by heterogeneity in risks. I distinguish between risk preferences and demand frictions underlying the residual variation. Demand frictions induce a systematic difference between the true and revealed value of insurance. Using a sufficient statistics approach that accounts for this alternative source of heterogeneity, I find that the welfare conclusions regarding adversely selected markets are substantially different. The source of heterogeneity is also essential for the evaluation of policy interventions intended to reduce adverse selection like insurance subsidies and mandates, risk-adjusted pricing and information policies.

  • Rewarding Schooling Success and Perceived Returns to Education: Evidence from India - REVISED - (with Sandra Sequeira and Guo Xu)

    Abstract: This paper tests two specific mechanisms through which individuals may form expectations about returns to investments in education: receiving recognition for one's schooling performance, and exposure to successful students through family or social networks. Using a regression discontinuity design, we study the impact of a fellowship program recognizing the schooling performance of young girls in secondary school in India. We find that the fellowship award is associated with a significant increase in the perceived value of education, by both increasing the perceived mean of earnings and decreasing the perceived variance in earnings associated with additional years of schooling. Being exposed to successful students does not affect perceived returns to education for those in their family or social networks. This exposure is however associated with holding more information on potential sources of funding for schooling and a higher intention to apply for the fellowship.

  • Revising Claims and Resisting Ultimatums in Bargaining Games - R&R at Review of Economic Design - (with Frans Spinnewyn)

    Abstract: We propose a mechanism which implements a unique solution to the bargaining problem with two players in subgame-perfect equilibrium. Players start by making claims and accept a compromise only if they cannot gain by pursuing their claim in an ultimatum. The player offering the lowest resistance to his opponent's claim can propose a compromise. The unique solution depends on the extent to which claims can be revised. If no revisions are allowed, compatible claims implement the Nash solution. If all revisions are allowed, maximal claims implement the Kalai-Smorodinsky solution.
