    Insurance, Redistribution, and the Inequality of Lifetime Income

    Individuals vary considerably in how much they earn during their lifetimes. This study examines the role of the tax‐and‐transfer system in mitigating such inequalities, which could otherwise lead to disparities in living standards. Utilizing a life‐cycle model, we determine that the tax‐and‐transfer system offsets 45% of lifetime earnings inequality attributed to differences in productive abilities ...

    Income Effects of Disability Benefits

    We provide novel evidence about the incentive and welfare effects of an increase in the generosity of disability benefits. Importantly, a unique policy variation in Germany allows us to isolate the income effect of a change in benefit generosity. We leverage this quasi-experimental policy variation using an RD design to estimate the effect of increasing disability benefits on employment, earnings, ...

    The gender pension gap, the difference in pension entitlements between men and women, is 32 percent for 60-yearolds according to data from the German Pension Insurance (Deutsche Rentenversicherung). In addition, there is a considerable motherhood pension gap: Statutory pension entitlements for mothers and childless women differ greatly. Pension-related childcare credits, which were introduced in 1986 ...

    The Effect of Pension Wealth on Employment

    This study provides novel evidence about the pension wealth elasticity of employment. For the identification we exploit reform-induced variation of pension wealth that is related to the number of children but which does not affect the implicit tax rate of employment. We use a difference-in-differences estimator based on administrative data from the German pension insurance and find that, on average, ...

Using administrative data that comprises a 10 percent random sample of the Australian population and a natural experimental design, we investigate the effects of natural disasters on retirement savings in the aftermath...

    Increasing disability benefits: selection and labor market effects.

    We study the incentive and labor market effects of disability benefit programs using unique policy variation in Germany. In 2014, disability benefits of new recipients were increased considerably while eligibility criteria were not changed. We exploit this quasi-experimental policy variation to test the implications at two different margins. First, we analyze to what extent an increase in the...
