The phenomenon of entrepreneurship has attracted researchers from a variety of disciplines and a diverse number of analytical approaches. Currently, there is a considerable amount of confusion and a variety of conflicting theories which are being used interchangeably and ambiguously.

In this important new book, the authors argue that there are analytically distinct forms of entrepreneurship, each of them having an individual logic of their own. They highlight the role of individual economic agents with endowments of new knowledge or new combinations of old knowledge as entrepreneurs, and thus identify them as dynamic factors in the knowledge economy.

Overall, this book not only provides a contemporary overview of current research in the field, but also summarizes the policy conclusions that can be drawn from current research.
