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...

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...

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...

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...

We measure the effective assistance to 17 Norwegian private industries in 1989 and 1991 caused by government budgetary subsidies, indirect commodity taxes, import protection through nominal tariffs and non-tariff barriers, and electricity market distortions. The assistance effects are measured...

An indicator of allocation effects of industrial policy is derived from a theoretical framework of monopolistic competition. The indicator gives a qualitative picture of how industrial policy affects industry structure and resource allocation, it identifies the policy measures that work as...

This paper studies how productivity shifts at the level of the firm are transmitted to aggregate industry productivity in a model of heterogeneous firms. We analyse both uniform productivity shifts, and catching up by reducing the productivity differentials between firms. The two kinds of shifts...

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...

It is an established fact that firms, even within narrowly defined industries, differ with respect to productivity. In this paper we analyse how observed heterogeneity in productivity is affected by endogenous producer behaviour, and to what extent shifts in firm specific productivity parameters...

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...
