Abstract

It has been seventeen years since I published a paper (Nelson 1991) concerned with the determinants and consequences of firm differences. I have been pondering the question of whether I now have anything useful to say about it that I did not say then. I don’t know, but let me give it a try. I begin by reflecting on what we might learn from studies of biological evolution about the importance of narrative and qualitative observation in analysis of the factors behind and consequences of firm differences. Then, I turn to commentary and criticism of what I think has been the dominant point of view (certain authors clearly are exceptions) orienting the studies of firm differences and industrial dynamics using the available longitudinal industry-firm data sets. Finally, I lay out some of my own rethinking regarding the sources and consequences of firm differences.


Keywords: Firms, Variation
