Studying Consumption Patterns using Registry Data: Lessons From Swedish Administrative Data

Jonas Kolsrud, Camille Landais, and Johannes Spinnewijn

November 2017

This paper measures consumption expenditures using registry data on income and asset holdings in Sweden and illustrates how a registry-based measure can alleviate some critical limitations of traditional survey measures in capturing changes in consumption inequality and consumption responses to shocks. In the construction of our measure, we build on previous work exploiting the identity coming from the household budget constraint between consumption expenditures and income net of savings. We try to improve this measure using more registry information to account for the contribution of both nancial and real assets to consumption ows. We demonstrate the power of the registry-based measure to study the relationship between income and consumption inequality, especially at the top of the income distribution. We also exploit the longitudinal dimension to study consumption responses to important life-time events and the di erent means used to smooth consumption.

The Optimal Timing of Unemployment Benefits: Theory and Evidence from Sweden

Jonas Kolsrud, Camille Landais, P Nilsson, and Johannes Spinnewijn

June 2017

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 off insurance and incentives, our analysis suggests that the flat 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 introduction of a declining tilt in the profile.
