The European Court of Justice's definition of when a firm has a dominant position has recently come under attack as being meaningless and impossible to measure. We argue that both attacks are wrong, suggest an economic interpretation of domination and propose how it may be measured using modern...

The aim of the paper is to examine the relationship between R&D capital and productivity using micro data for Danish manufacturing firms. We account for the influence of factors such as ownership, innovative characteristics and source of funding. The return to accumulated R&D capital is...

In this paper we analyse the determinants of R&D spending in Danish firms and firms and industries in the nineties. We also examine the complementarity and substitution between publicly and company financed spending taking into account the influence from market structure, barriers of entry,...
