I am a Postdoc at the Department of Economics at the Stockholm School of Economics, going on the 2024/25 Jobmarket.

My research interests are macroeconomics, public policy, demography, welfare, and inequality. My work combines computational models and  micro data to analyze pertinent policy issues.

Jobmarket Paper

Does Student Aid Improve Educational Mobility?
with Johanna Wallenius. Link to latest version.

Abstract: Universal education systems are often said to promote intergenerational mobility. However, educational mobility in Denmark, which offers tax-financed post-secondary education and generous student aid, is still surprisingly low. To rationalize this, we develop a structural life cycle model where education choice is endogenous and depends on preferences, graduation probabilities, and parental transfers, which vary with child ability and parental education. After estimating the model on Danish register data, we first disentangle the drivers of educational mobility. Subsequently, we conduct counterfactual policy experiments to evaluate the scope for education policy to improve mobility. We find that increasing current subsidies has only small positive effects on educational attainment and mobility, while relaxing the student debt limit has virtually no effect. This is so as the persistent transmission of skills and preferences dominate immediate pecuniary incentives.

Population Aging, Public Finances, and Alternatives for Retirement Reform
with Tim Dominik Maurer. Link to latest version

Abstract: We study retirement reforms that ensure sustainable public finances in the face of population aging. We build a structural life-cycle model with a pension scheme that includes a public pay-as-you-go pillar and a mandatory fully-funded pillar. The two pillars interact through a means-testing mechanism. The higher the fully-funded benefit, the lower the public pay-as-you-go benefit. The interaction allows us to assess a reform in which increases in fully-funded contributions and benefits reduce public pension benefits through means testing. We compare this reform to three alternatives: Increasing the retirement age, cutting public benefits, and increasing taxes to finance growing public pension expenditures. We estimate the model to Danish micro data and find that expanding fully-funded pensions to indirectly lower public pensions yields the highest welfare. Among the remaining reforms, we show that directly lowering public benefits outperforms hiking taxes and increasing the retirement age.
