This is a review of Joel Mokyr's fascinating book entitled A Culture of Growth. The work is summarized, noting its focus on Darwin-style evolutionary explanations of cultural change. But Mokyr's emphasis on cultural entrepreneurs and positive feedbacks in the procreation of ideas is insufficient to explain the origins of modern economic growth. Too much explanatory weight is placed on too few extraordinary people. It is argued that Mokyr's analysis should be extended, to bring the evolution of institutions, as well as the evolution of culture, into the picture at an additional level. The role of inter-state rivalry and exogenous shocks has also to be underlined. This kind of analysis can be developed within the framework of generalized Darwinism, which Mokyr himself adopts. This is a major and highly stimulating book.

This paper proposes a new conceptualization of business model (BM) that rigorously exploits the important insights this notion offers and links them to related views developed in economics and business studies. We develop the foundations of a BM concept consistent with the principles of generalized Darwinism (GD) and with contributions already developed within this framework. Thus, we demonstrate the relevance of GD as a unifying framework for developing the evolutionary theory of firm and industry. We suggest analysing BM as a generative replicator hosted by the firm, which structures interactions between the members of this organization and the social entities of its industrial environment. We argue that GD allows us to clarify the nature and boundaries of the BM concept and to specify its relationships to other key evolutionary concepts, such as organizational routines.
