This paper examines the sources of differences in social mobility between the U.S. and Denmark. Measured by income mobility, Denmark is a more mobile society, but not when measured by educational mobility. There are pronounced nonlinearities in income and educational mobility in both countries....

This paper analyzes the effects of Denmark's Start Aid welfare reform that targets refugees. Implemented in 2002, it enables us to study not only the reform's immediate effects, but also its longer-term consequences, and its repeal a decade later. The reform-induced large transfer cuts led to an...

Denmark's Start Aid welfare reform reduced benefits to refugee immigrants by around 50 percent for those granted residency after the reform date. The reform led to a sharp short run increase in labor earnings and employment, but it also induced a strong female labor force withdrawal, and a large...

This paper studies whether an exogenous reduction in the criminal activity of one individual lowers crimes committed by other young men who live in the immediate neighborhood. Using the randomness of a child's gender, we first show that men who father their first child at a very young age are...

This paper investigates the effects of school starting age on crime while relying on variation in school starting age induced by administrative rules; we exploit that Danish children typically start first grade in the calendar year they turn seven, which gives rise to a discontinuity in...

This paper studies the effects of a large welfare benefit reduction on the children in the affected families. The welfare cut targeted adult refugees who received residency in Denmark, and it reduced their disposable income by 30 percent on average over the first five years. We show that...

This paper studies intergenerational income mobility using register data for 630,000 Danish children and their parents. We document substantial mobility differences across parents' income levels. Decomposing the mobility estimates shows that for children from low income families,...

This paper studies the interaction between parental and public inputs in children's skill formation. We perform a longer-run follow-up study of a randomized controlled trial that increased preschool quality and initially improved skills significantly for children of all backgrounds. There is,...

We show how tax kinks can be used to estimate the marginal propensity to consume (MPC). Tax kinks create discrete changes in the relationship between taxable income and disposable income, which – under a set of testable assumptions – enables causal identification of the spending response to...
