This paper studies the role of intrinsic motivation, reputation and reciprocity in driving open source software innovation. We exploit the observed pattern of contributions – the ‘revealed preference’ of developers – to infer the underlying incentives. Using detailed information on code...

Using new data on citations to university patents and scientific publications, we study how geography affects university knowledge spillovers. Citations to patents decline sharply with distance and are strongly constrained by state borders. The effect of distance on citations to scientific...

We study the impact of private ownership, incentive pay and local development objectives on university licensing performance. We develop and test a simple contracting model of technology licensing offices, using new survey information together with panel data on U.S. universities for 1995-99. We...

Using new data on citations to university patents and scientific publications, we study how geography affects university knowledge spillovers. Citations to patents decline sharply with distance up to about 150 miles and are strongly constrained by state borders. Distance also constrains...

We study the impact of private ownership, incentive pay, and local development objectives on university licensing performance. We develop and test a simple contracting model of technology-licensing offices using new survey information together with panel data on U.S. universities for 1995-99. We...

This paper studies the role of intrinsic motivation, reputation, and reciprocity in driving open source software innovation. Unlike previous literature based on survey data, we exploit the observed pattern of contributions - the .revealed preference. of developers - to infer the underlying...
