This paper demonstrates that a large economic shock such as an oil boom increases intergenerational earnings mobility among directly affected men, mostly through increased bottom-up mobility, but not for women. Preexisting local differences in mobility or shifts in the earnings distributions do not drive these findings. Instead, changes in relative earnings paid to workers with different skills offer the best explanation. Moreover, we document that intergenerational mobility is significantly higher for the indirectly affected third generation and that the oil boom broke the earnings link between first- and third-generation men.

We examine the effect of radiation exposure in utero, resulting from nuclear weapon testing in the 1950s and early 1960s, on long-run outcomes of Norwegian children. Exposure to low-dose radiation, specifically during months 3 and 4 in utero, leads to lower IQ scores for men and lower education attainment and earnings among men and women. Children of persons affected in utero also have lower cognitive scores, suggesting a persistent intergenerational effect of the shock to endowments. Given the lack of awareness about nuclear testing in Norway at this time, our estimates are likely unaffected by avoidance behavior or stress effects.

This paper studies the long-term and life cycle consequences of increasing access to mother and child health care centers in the first year of life. Access to these centers increased completed years of schooling by 0.15 years and earnings by 2%. These effects were stronger for children from a low socioeconomic background and contribute to a 10% reduction in the intergenerational persistence in educational attainment. Better nutrition within the first year of life is a likely mechanism. In particular, we find positive effects on adult height, fewer health risks at age 40, and decreased infant mortality from diarrhea.

Given the wide use of child care subsidies across countries, it is surprising how little we know about the effect of these subsidies on children's longer-run outcomes. Using a sharp discontinuity in the price of child care in Norway, we are able to isolate the effects of child care subsidies on both parental and student outcomes. We find very small and statistically insignificant effects of child care subsidies on child care utilization and parental labor force participation. Despite this, we find significant positive effect of the subsidies on children's academic performance in junior high school, suggesting that the positive shock to disposable income provided by the subsidies may be helping to improve children's scholastic aptitude.

Using Norwegian data, we examine effects of school starting age (SSA). Unlike much recent literature, we can separate SSA from test age effects using scores from IQ tests taken outside school at about age 18. We find a small, negative effect of starting school older but much larger positive effects of age at test. Also, starting older leads to lower earnings until about age 30. We find little impact of SSA on educational attainment, but boys who start older are less likely to have poor mental health at age 18. Additionally, starting school older has a negative effect on the probability of teenage pregnancy.
