Research expenditures , technology transfer activity , and university licensing revenue

In this paper we relate university licensing revenues to both university research expenditures and characteristics of the university and the university technology transfer office. We apply the Hausman–Taylor estimator for panel data with time-invariant explanatory variables and the Arellano–Bover dynamic panel model to unbalanced panels for the years 1991–2003 and balanced panels for the years 1995–2003. We find conflicting evidence regarding the short-term impacts of research expenditures on licensing revenues. On the other hand, both early initiation of technology transfer programs and staff size increase expected licensing revenues. Staff size and early entry appear to be substitutes, however. One-year lagged licensing revenue has strong predictive power for current licensing revenue. Further research is necessary to analyze changes in technology transfer office efficiency over time and the contribution of technology transfer to larger university missions.
