The ultimate goal of any world-class swimmer is to break a record, and technology enables that accomplishment. Using 40 years of data at the individual, national and international level, we identify the quantitative impact that innovation has had on the number of record breaks. We find small but...

This paper examines the location of innovations within green technology, using U.S. patent citation data to trace their inter-generational knowledge flows over time. Clustering is clearly evident, and we use multivariate left-censored Tobit regression analysis to control for identifiable...

With the recent liberalization of technology flows, changes in the pattern of domestic invention can be expected in Brazil. This paper models the decision of a firm to engage in innovative activity and to protect the results of that activity. Using a unique firm-level dataset collected for this...

This paper tests the induced innovation hypothesis that higher oil prices will lead to increased innovation in energy-efficient automotive technology. We find robust empirical support for the hypothesis, while using various measures of oil and gas prices and controlling for other factors...

Recent liberalization of technology flows in several less developed nations necessitates study into the possible effects of this significant shift in policy. This paper uses a unique firm-level dataset, modeling the choice between R&D expenditures and technology licensing behavior in Brazil,...

There are two counter-intuitive trends in technological collaboration currently at work, making collaborative patent applications less common but where they exist, the collaborations involve more partners. Patent data are used to examine these trends along with the impact of two recent policy...
