Wealth is highly correlated between parents and their children; however, little is known about the extent to which these relationships are genetic or determined by environmental factors. We use administrative data on the net wealth of a large sample of Swedish adoptees merged with similar...

Studies on the intergenerational transmission of human capital usually assume a one-way spillover from parents to children. But what if children also affect their parents' human capital? Using exogenous variation in education, arising from a Swedish compulsory schooling reform in the 1950s and...

We examine how the gender of a sibling affects earnings, education and family formation. Identification is complicated by parental preferences: if parents prefer certain sex compositions over others, children's gender affects not only the outcomes of other children but also the existence of...

We introduce a novel strategy to study the intergenerational transmission of human capital, net of genetic skill transfers. For this purpose, we use unique data on children conceived through sperm and egg donation in IVF treatments in Denmark. Because the assignment of donors is not selective,...

Learning-by-doing is a fundamental concept in economics but a challenging one to document in high-skilled settings due to non-random assignment of workers to tasks and lacking performance measures. Our paper overcomes these challenges in the context of heart attack treatments in Sweden, where we...

Over the last century, global life expectancy has increased tremendously. A longer planning horizon may change individuals' incentives to work, save, and marry but it has proven challenging to disentangle such incentive effects from those of improved health. In this paper, we study how...

Longer life expectancy can affect individuals' incentives to work, save, and marry, net of any changes in their underlying health. We test this hypothesis by using the sudden arrival of a new treatment in 1995 that dramatically increased life expectancy for HIV-infected individuals. We compare...

Although learning-by-doing is believed to be an important source of productivity growth there is limited evidence that production volume affects productivity in a causal sense. We document evidence of learning-by-doing in a high-skill profession where stakes are high; advanced cancer surgery....

In this paper, we study the short-run effect of salary receipt on mortality among Swedish public sector employees. By exploiting variation in pay-days across work-places, we completely control for mortality patterns related to, for example, public holidays and other special days or events...
