Why do individuals choose different types of post-secondary education, and what are the labor market consequences of those choices? We show that answering these questions is difficult because individuals choose between several unordered alternatives. Even with a valid instrument for every type...

Many developed countries currently consider a move towards a universal child care program. The challenge in assessing the case for universal child care programs is that the evidence base is scarce. We analyze the staged expansion of subsidized, universally accessible child care in Norway. Our...

Most nations spend a considerable part of their gross domestic product (GDP) on defense. However, no previous study has addressed the productivity and efficiency of the core area of the armed forces, operational units, using Data Envelopment Analysis (DEA). Introducing a model for the production...

Norwegian administrative data are used to evaluate the impact of a doubling of the threshold in the retirement earnings test. We find almost no impact on the extensive margin, but a positive effect on the intensive margin. This positive effect is uneven over the earnings distribution, and...

I present a theory on the relationship between educational choice and entrepreneurship in a labour market with asymmetric information. The model shows that, in a labour market where education is used as a signalling device, an imperfect relationship between productivity in education and in the...
