Despite important policy implications associated with the allocation of education resources, evidence on the effectiveness of school inputs remains inconclusive. In part, this is due to endogenous allocation; families sort themselves non-randomly into school districts and school districts...

Using a matched employer-employee data set for Norway, we exploit rare information on the union status of both individual employees and their workplaces. We establish two key results. First, we find a positive effect of workplace trade union density on the level of the individual's pay in...

Failure to account for differences between immigrants and natives in their responsiveness to changes in macroeconomic conditions may bias estimates of assimilation effects on immigrant earnings. Using Norwegian register data from 1980 to 1996, we first establish that earnings of immigrants from...

The regional unemployment elasticity of annual earnings for non-OECD immigrants is found to be more than three times larger than for natives, using micro data covering all immigrants in Norway in 1990 and a random sample of natives. The decline in relative earnings of non-OECD immigrants from...

We investigate the effects of a large-scale Norwegian reform that provided extra teachers to 166 lower secondary schools with relatively high student-teacher ratios and low average grades. We exploit these two margins using a regression discontinuity setup and find that the reform reduced the...

We study how the adoption of battery electric vehicles -- a key technology for decarbonizing transportation -- responds to two local privileges: road toll exemption and bus lane access. Combining rich Norwegian microdata with a quasi-experimental research design where we exploit household-level...

We examine employment effects of the COVID-19 crisis in Norway during the initial lockdown, through the subsequent recovery, and after the dust had settled. While we identify large and socially skewed effects of the crisis through its early phases, we find no long-term effects on employees...

We study how the adoption of battery electric vehicles – a key technology for decarbonizing transportation – responds to two local incentives: road toll exemption and bus lane access. Combining rich Norwegian microdata with a quasi-experimental research design where we exploit...

We follow the same children before and after they receive their first child welfare service (CWS) record, and compare the trajectories of those assigned to foster care with those that received home-based CWS in an event-study framework. To account for the fact that children who start receiving...
