We present a model of endogenous firm growth with R&D investment and stochastic innovation as the engines of growth. The model for firm growth is a partial equilibrium model drawing on the quality ladder models in the macro growth literature, but also on the literature on patent races and the...

We examine the role of the Norwegian education system in explaining the moderate and stable earnings dispersion in Norway. Estimating earnings equations for 1980 and 1990, we find that returns to education have been remarkably stable in Norway, also when we compare returns to education across...

Using a set of panel data for manufacturing plants we study how payrll taxes and investment subsidies affect wages and demand for labor and capital. We exploit changes in the regional subsidy schemes for labor anf capital in Norway. Our empirical analysis finds that a large part of changes in...

This paper presents a somewhat new econometric framework that permits simultaneous estimation of price-cost margins, scale economies and productivity from a panel of establishment data. The econometric model contains only a few, economically interesting parameters to be estimated, but it is...

Using panel data for the Norwegian manufacturing, we revisit " the increasing returns to scale puzzle" for labour input. We consider the response of the input of white collar workers, blue collar workers, and blue collar worker hours to permanent changes in output. Permanent and temporary...

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...

A number of market failures have been associated with R&D investments and significant amounts of public money have been spent on programs to stimulate innovative activities. In this paper, we review some recent microeconometric studies evaluating effects of government-sponsored commercial R&D....
