Stuart and Waverly Ding of Berkeleys Haas School of Business take a randomly selected sample of 5,100 life science Ph.D.s in academia, and examine the link between participation in for-profit entrepreneurial ventures and the presence of an academic social network that supports faculty entrepreneurism. They find that university scientists are more likely to found or join the board of a new firm if other faculty members have already done so, particularly if more prestigious colleagues in their department have created their own start-ups. They also find evidence that more accomplished faculty members are more likely to help commercialize technologies and to lead the way in fostering an entrepreneurial climate within a university department.
