Entrepreneurship is the engine of economic progress, but mainstream economic models of economic growth tend to leave out the entrepreneurial elements of the economy. This new book from Randall Holcombe begins by identifying areas in which evolutionary and Austrian approaches differ from the academic mainstream literature on economic growth, before moving on to distinguish growth from progress.The author then analyzes economic models of the firm based on the idea that it is entrepreneurship that drives economic progress. The book should prove to be a natural successor to recent Routledge books by Frederic Sautet and David Harper.
