The aim of this authoritative selection is to synthesize the burgeoning, heterogeneous literature on institutions and agents engaged in technological entrepreneurship at universities. These studies highlight the importance of institutional incentives and organizational practices in stimulating entrepreneurship, and clearly demonstrate the multiplicity of stakeholder objectives, perceptions and outcomes relating to it. However the evidence is much less clear on the effectiveness of property-based institutions designed to promote technological entrepreneurship, such as science parks and incubators. The volume covers four related topics: university licensing and patenting; science parks and incubators; university-based start ups; and the role of academic science in entrepreneurship.Professor Siegel - a leading authority in the field - has written a scholarly new introduction which summarizes the key findings of these studies and discusses their managerial and policy implications.
