Knowledge Spillover Entrepreneurship & Innovation: The Role of Universities David B. Audretsch
The Traditional University
• The Humboldt Model (Wilhelm von Humboldt, 1767-1835)
• Freedom & independence of research & teaching
• “knowledge for its own sake”
• Little valuation for engagement & societal impact
Role of University in the Solow Economy
• Limited contribution for investment in physical capital
• Limited link to (exogenous) knowledge
• Contribution in terms of social and political values
• Limited contribution to economic development
Role of University in the Romer Economy
• Competitiveness Crisis of 1970s
• Comparative advantages shifts from physical capital of knowledge
• University is source of knowledge
• University financial shortfall
• Demand oriented
The Knowledge Filter
“A wealth of scientific talent at American colleges and universities – talent responsible for the development of numerous innovative scientific breakthroughs each year – is going to waste as a result of bureaucratic red tape and illogical government regulations…What sense does it make to spend billions of dollars each year on government-supported research and then prevent new developments from benefiting the American people because of dumb bureaucratic red tape?” U.S. Senator Birch Bayh, 1980
The Bayh-Dole Act of 1980
• Penetrate the Knowledge Filter • Creation of the Technology Transfer Office (TTO) • Most studies analyzing commercialization of
university research limited to measures of what the TTO does
• Intellectual property disclosed to and registered by TTO may lead to systematic underestimation of commercialization and innovation emantating from university research (Thursby & Thursby, 2005; Shane, 2004)
Emergence of Entrepreneurial University • Facilitate knowledge spillovers from university
• University as solution provider – user oriented fields and programs (i.e. biochemistry, informatics)
• Demand orientation rather than “knowledge for its own sake”
• Provision of conduits for knowledge spillovers – technology transfer offices, incubators, science parks, sponsored research
--(Shiri M. Breznitz and Maryann P. Feldman, “The Engaged University,” Journal of Technology Transfer, 2012)

Disappointing Assessment of Technology Transfer
Paucity of University Entrepreneurship?
• AUTM reports annual mean of 426 startups from U.S. Universities
• MIT TTO reported 29 startups
• Stanford TTO reported 6 startups
• Based on AUTM data, one startup generated per $368 million of R&D
Has Knowledge Spillover Entrepreneurship from Universities been Underestimated?
• Most studies analyzing commercialization of university research limited to measures of what the TTO does
• Intellectual property disclosed to and registered by TTO may lead to systematic underestimation of commercialization and innovation emantating from university research (Thursby & Thursby, 2002, “Who Is Selling the Ivory Tower?” Management Science; Shane, 2004, “Technological Opportunities and New Firm Creation,” Management Science)

Measuring Knowledge Spillover Entrepreneurship from Universities
• 16,693 scientists awarded National Cancer
Institute (NCI) grant, 1998-2002 (top 20%)
• $5,350 million NCI grant awards
• NCI awards matched to patents
• 398 distinct patentees, (1,204 patents), 1998-2004
• 1 in 4 scientists started new business
Aldridge & Audretsch, “The Bayh-Dole Act and Scientist Entrepreneurship”, Research Policy, 2011.
Knowledge Spillover Entrepreneurship from Unviersities • Measurement of scientist entrepreneurship by
AUTM & university TTO’s may underestimate extent of scientist entrepreneurship
• Based on AUTM data, one startup generated per $368 million of R&D
• Aldridge & Audretsch (Research Policy, 2011) implies one startup generated per $12 million of R&D
Limitations of Previous Research on University Knowledge Spillover Entrepreneurship • Limited to a single field of science – cancer research
• Limited to the highest performing scientists
• Unanswered questions
– “To what extent is the high rate of entrepreneurial activity exhibited by the high performing cancer research scientists prevalent across different types of scientific fields for different types of scientists?”
-- “To what extent do the main determinants of scientist entrepreneurship hold across different scientific fields & heterogeneous types of scientists?
Purpose of Paper
• Ask What Scientists Do & Not What the TTO Does to Commercialize Research
• Move Beyond Traditional Individual-Specific Characteristics in Explaining Propensity for Scientist to Engage in Entrepreneurship
• Move Beyond University Characteristics in Explaining Scientist Commercialization
• Why & How Do Scientists Become Entrepreneurs?
Creating a Scientist Entrepreneurship Database • Web of knowledge database contained email addresses of
9361 scientists that received NSF funding between 2005 and 2012-Q2.
• Online survey questionnaire directed to the entire population of 9361 scientists in the first round of survey administration
• 30 scientists were on sabbatical, 9 scientists were inactive, and email addresses of 172 scientists were returned since they were incorrect/incomplete.
• Survey sample of 9150 scientists (97.75 percent of the population
Creating a Scientist Entrepreneurship Database
• Scientists spanned 6 different fields of research,
•1899 scientist responses (response rate of 20.75%) from three rounds of administering questionnaire
Hypothesis 1: Age is positively related to the propensity for scientists to become an entrepreneur • For general entrepreneurship literature, age has negative
impact on entrepreneurship (Parker, 2010, The Economics of Entrepreneurship, Oxford University Press; Reynolds, Carter, Gartner & Greene (2004) “The Prevalence of Nascent Entrepreneurs in the United States: Evidence from the Panel Study of Entrepreneurial Dynamics,” Small Business Economics)
• Levin and Stephan, (1991), “Research Productivity Over the Life Cycle; Evidence for Academic Scientists,” American Economic Review; Stephan, Paula., & Levin, Sharon (1992), Striking the Mother Lode in Science: the Importance of Age, Place, and Time, Oxford University Press
Hypothesis 2: Female scientists less likely to be an entrepreneur
• Studies from general population find likelihood of female entrepreneurship lower than male entrepreneurship (Minniti & Nardone (2007) “Being in Someone Else’s Shoes: The Role of Gender in Nascent Entrepreneurship,” Small Business Economics)
• Aldridge & Audretsch (2011) find no difference for gender for cancer scientists
Hypothesis 3: The propensity for a scientist to become an entrepreneur is positively related to human capital • Positive relationship found between human
capital and entrepreneurship for general population (Davidsson & Honig (2003) “The role of Social and Human Capital among Nascent Entrepreneurs,” Journal of Business Venturing)
• Aldridge & Audretsch (2011) find human capital to have no impact on scientist entrepreneurship for cancer researchers
Hypothesis 4: Social capital is positively related to the propensity for a scientist to become an entrepreneur
• Positive relationship found between social capital and entrepreneurship for general population (Aldrich & Martinez (2010), “Entrepreneurship as Social Construction,” in Handbook of Entrepreneurship)
• Mosey & Wright, Michael (2007) “From Human Capital to Social Capital: A Longitudinal Study of Technology Based Academic Entrepreneurs,” Entrepreneurship Theory and Practice and Aldridge & Audretsch (2011) find social capital to be most important determinant of scientist entrepreneurship for cancer researchers
Hypothesis 5: Scientist entrepreneurship is positively related to the resources available to the technology transfer office • Clarysse, Wright, Lockett, Van de Velde, &
Vohora (2005) “Spinning Out New Ventures: A Typology of Incubation Strategies from European Research Institutions,” Journal of Business Venturing
• Di Gregorio & Shane (2003), “Why Some Universities Generate More TLO Start-Ups than Others?”, Research Policy
Hypothesis 6 Access to financial resources is positively related to scientist entrepreneurship
• For general population, access to financial resources found to have positive impact on entrepreneurship (Gompers &Lerner (2010), “Equity Financing,” in Handbook of Entrepreneurship Research)
• Access to financial resources positively influences entrepreneurship for high-tech & knowledge industries (Kerr & Nanda (2009) “Financing Constraints and Entrepreneurship,” National Bureau of Economic Research Working Paper
Creating a Database
• Web of knowledge database contained email addresses of 9361 scientists that received NSF funding between 2005 and 2012-Q2.
• Online survey questionnaire directed to the entire population of 9361 scientists in the first round of survey administration
• 30 scientists were on sabbatical, 9 scientists were inactive, and email addresses of 172 scientists were returned since they were incorrect/incomplete.
• Survey sample of 9150 scientists (97.75 percent of the population

Conclusions
• Knowledge spillover entrepreneurship from universities more prevalent than reflected in extant literature
• Knowledge spillover entrepreneurship varies across scientific fields
• Determinants of knowledge spillover entrepreneurship from universities do not mirror determinants for more general population
• Determinants of knowledge spillover entrepreneurship entrepreneurship vary considerably across scientific fields
