I just learned (via Rajshree Agarwal) of the passing, at a young age, of Steven Klepper. Steven was an acquaintance of many years, a stand-up guy as well as a great researcher. His work on the lifecycle of firms and the role of spinoffs is a model for how to do good empirical work in organization and technology. By coincidence, this new paper (with Russell Golman) crossed my screen only a few minutes after I learned the news.
Geographic clustering of industries is typically attributed to localized, pecuniary or non-pecuniary externalities. Recent studies across innovative industries suggest that explosive cluster growth is associated with the entry and success of spinoff firms. We develop a model to explain the patterns regarding cluster growth and spinoff formation and performance, without relying on agglomeration externalities. Clustering naturally follows from spinoffs locating near their parents. In our model, firms grow and spinoffs form through the discovery of new submarkets based on innovation. Rapid and successful innovation creates more opportunities for spinoff entry and drives a region’s growth.
