Working Papers

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

    Abstract: This paper provides a simple, yet general framework to analyze the optimal time profile of benefits during the unemployment spell. We derive simple sufficient-statistics formulae capturing the insurance value and incentive costs of unemployment benefits paid at different times during the unemployment spell. Our general approach allows to revisit and evaluate in a transparent way the separate arguments for inclining or declining profiles put forward in the theoretical literature. We then estimate our sufficient statistics using administrative data on unemployment, income and wealth in Sweden. First, we exploit duration-dependent kinks in the replacement rate and find that the moral hazard cost of benefits is larger when paid earlier in the spell. Second, we find that the drop in consumption determining the insurance value of benefits is large from the start of the spell, but further increases throughout the spell. On average, savings and credit play a limited role in smoothing consumption. Our evidence therefore indicates that the recent change from a flat to a declining benefit profile in Sweden has decreased welfare. In fact, the local welfare gains push towards an increasing rather than decreasing benefit profile over the spell.

  • Heterogeneity, Demand for Insurance and Adverse Selection - R&R at American Economic Journal: Economic Policy - (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.
