Faculty entrepreneurs and research productivity

In this paper, we analyze the research productivity of faculty entrepreneurs at 15 research institutes using a novel database combining faculty characteristics, licensing information, and journal publication records. We address two related research questions. First, are faculty entrepreneurs more productive researchers ("star scientists'') compared to their colleagues? Second, does the productivity of faculty entrepreneurs change after they found a firm? We find that faculty entrepreneurs in general are more productive researchers than control groups. We use multiple performance criteria in our analysis: differences in mean publication rate, skewness of publication rate, and impact of publications (journal citation rate). These findings bring together previous work on star scientists by Zucker, Darby, and Brewer [Zucker, L. G., Darby M. R., & Brewer M. B. (1998). The American Economic Review, 88, 290-306.] and tacit knowledge among university entrepreneurs by Shane [Shane, S. (2002). Management Science, 48, 122 -137.] and Lowe [Lowe, R. A. (2001). In G. Libecap (Ed.) Entrepreneurial Inputs and Outcomes. Amsterdam: JAI Press, Lowe, R. A. (2006). Journal of Technology Transfer, 31(4), 412 - 429]. Finally, we find that faculty entrepreneurs' productivity not only is greater than their peers but also does not decrease following the formation of a firm.
