Firm growth in the Swedish energy sector: Will large firms become even more dominant?
Abstract
This paper examines the determinants of firm growth in the Swedish energy sector using a sample of 200 energy firms active from 2000 to 2010. The article has two aims. First, we seek to investigate whether there is reason to believe that the Swedish energy market will become more concentrated in the future, dominated by a few firms. That would be the result if, for example, large firms systematically and over time grew faster than the smaller firms in the Swedish market. Second, we investigate whether firm growth can mainly be explained by firm-specific variables, supporting Penrose's [1] suggestion that internal resources are the key determinants of firm growth rates. To this end, quantile regression is used in addition to ordinary least squares regression, to provide a more complete estimation of the growth distribution of firms conditional on different attributes. The results indicate that large firms do not grow faster than other firms in the sector, and that energy firms' internal resources are indeed the key determinants of firm growth in the Swedish energy industry.
