Children with lower socioeconomic status (SES) tend to benefit more from early child care, but are substantially less likely to be enrolled. We study whether reducing behavioral barriers in the application process increases enrollment in child care for lower-SES children. In our RCT in Germany...

This paper studies the impact of speed limits on local air pollution, using a series of date specific speed limit reductions in Oslo over the 2004-2015 period. We find that lowering the speed limit from 80 to 60 km/h reduces travel speed by 5.8 km/h, but we find no effect on local air pollution....

This paper studies the impact of speed limits on local air pollution using a series of datespecific speed limit reductions in Oslo over the 2004-2011 period. We find that lowering the speed limit from 80 to 60 km/h reduces travel speed by 5.8 km/h. However, we find no evidence of reduced air...

What do the education premiums look like over the life cycle? What is the impact of schooling on lifetime earnings? How does the internal rate of return compare with opportunity cost of funds? To what extent do progressive taxes attenuate the incentives to invest in education? This paper...

This paper provides evidence on the returns to schooling in current and lifetime earnings. We use these results to assess the importance of life-cycle bias in earnings regressions using current earnings as proxy for lifetime earnings. To account for the endogeneity of schooling, we apply three...

We demonstrate how age-adjusted inequality measures can be used to evaluate whether changes in inequality over time are because of changes in the age structure. In particular, we explore the hypothesis that the substantial rise in earnings inequality since the early 1980s is driven by the large...

Using quasi-random assignment of criminal cases to judges, we estimate large incarceration spillovers in criminal and brother networks. When a defendant is sent to prison, there are 51 and 32 percentage point reductions in the probability his criminal network members and younger brothers will be...

Understanding whether, and in what situations, time spent in prison is criminogenic or preventive has proven challenging due to data availability and correlated unobservables. This paper overcomes these challenges in the context of Norway’s criminal justice system, offering new insights into...
