In this paper we develop a full information maximum likelihood method for the estimation of a joint model for the choice of length of schooling and the corresponding earnings equation. The model for schooling is assumed to be an ordered probit model, whereas the earnings equation is allowed to...

Do wage differences between workers with high and low levels of education, between males and females and between workers with different levels of experience reflect differences in productivity? We address this set of questions on the basis of a data set with variables for individual workers...

In this paper we develop likelihood based methods for statistical inference in a joint system of equations for the choice of length of schooling and earnings. The model for schooling choice is assumed to be an ordered probit model, whereas the earnings equation contains variables that are...

This paper investigates whether returns to experience and seniority vary between workers with different levels of education and between different types of firms. Using a large administrative dataset for Norwegian manufacturing, I find that more educated workers have higher experience and...

We find that the Norwegian R&D tax credit scheme introduced in 2002 mainly works as intended. The scheme is cost-effective and it is used by a large number of firms. It stimulates these firms to invest more in R&D, and, in particular, the effect is positive for small firms with little R&D...

This paper studies the distributions of literacy skills, education, and employment of immigrants and natives in three host countries: Canada, the United States, and Norway. For natives, we uncover remarkably stable relations between literacy skills, schooling, and employment across countries....

In 1998 the Norwegian government introduced a program that substantially increased parents’ incentives to stay home with children under the age of three. Many eligible children had older siblings, and we investigate how this program affected long-run educational outcomes of the older siblings....

The public health care systems in the Nordic countries provide high quality care almost free of charge to all citizens. However, social inequalities in health persist. Previous research has, for example, documented substantial educational inequalities in cancer survival. We investigate to what...

Empirical examination of whether R&D subsidies to private firms crowd out private investments has been hampered by problems related to selection. A particular worry is that research intentions and the quality of current research ideas may be correlated with the likelihood of applying for and...

We measure the effective assistance to 18 Norwegian private industries in 1989 caused by government budgetary subsidies, indirect commodity taxes, import protection through nominal tariffs and non-tariff-barriers, price discrimination of electricity and capital income taxation. The assistance...
