How does class size in compulsory school affect peoples’ long run education and earnings? We use maximum class size rules and Norwegian administrative registries allowing us to observe outcomes up to age 48. We do not find any indication of beneficial effects of class size reduction in...

This paper exploits discontinuous grade mixing rules in Norwegian junior high schools to estimate how classroom grade composition affects pupil achievement. Pupils in mixed grade classrooms are found to outperform pupils in single grade classrooms. This finding is driven by pupils benefiting...

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...

In econometrics some nonparametric instrumental regression models and nonparametric demand models with endogeneity lead to nonlinear integral equations with unknown integral kernels. We prove convergence rates of the risk for the iteratively regularized Newton method applied to these problems....

Deductibles in health insurance generate nonlinear budget sets and dynamic incentives. This paper uses detailed individual claims data from a large Swiss insurance company to estimate the response in health care demand to the discrete price increase that is generated by resetting the deductible...

Auf Grundlage von Daten des 'Survey of Health Ageing and Retirement in Europe' (SHARE) werden in diesem Beitrag einkommensbezogene Ungleichheiten in der Inanspruchnahme medizinischer und präventiver Leistungen in Deutschland analysiert und statistisch erklärt. Die Ergebnisse belegen...

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...

Traditional approaches to consumer demand modelling ignores the problem associated with product heterogeneity where important product characteristics are latent. The point of departure in the present study is a particular framework developed in Dagsvik (1996a,b) and Dagsvik et al. (1998). In...

This paper discusses a particular approach to empirical consumer demand modelling when products are differentiated and the product attributes are unobservable. In contrast to the traditional approach to this problem, see e.g. Epple (1987) and Deaton (1987, 1988), where the product variants are...

In conducting economic policy, governments generally face conflicts in various objectives, e.g. between efficiency and equity. In Norway, one objective of energy politics has been to reduce electricity consumption, and several tax increases have been proposed. Whether this objective may be in...
