Steven Klepper has made significant contributions to our understanding of the role of new firm entry in innovation and economic growth. His work is theoretical and integrative, firmly rooted in empirical observation of historical innovative processes, focusing on explaining “empirical regularities.” Klepper’s work integrates elements of traditional neoclassical models with evolutionary theory, bridging some of the gaps between neoclassical and evolutionary theory and between entrepreneurship research and mainstream economics.
In looking at the evolution of industries, Klepper explores regularities in the time paths of entry of new producers, exit of incumbent firms, industry output and price, and the rate of product and process innovation. To explain these regularities, he develops theories that feature differences in firm capabilities and the advantages of large firms in appropriating the returns from their innovative efforts. The theories are also used to explain differences in firms' innovative efforts, the composition of their innovative effort and their innovative success.
