Recent evolutionary theorizing about economic changeR.R.NelsonauthorEconomists long have employed evolutionary language and metaphors to characterize economic change, but until recently have largely eschewed the expression of explicit evolutionary theories. Over the last decade, however, a number of explicit evolutionary theories have been developed by economists, and other social scientists. This essay discusses the general analytic art form, and summarizes and discusses a number of the particular models. In the light of those examples, it evaluates the strengths and weaknesses of explicit evolutionary theorizing as an approach to understanding economic change.1995American Economic AssociationArticle
