Explores the geographic localization of knowledge spillover by comparing the location of inventors of citing patents to the location of the inventors of the patents they cite. The originating patents considered were from 1975 and 1980 and included all patents granted to U.S. universities and two...

Neoclassical economic theory predicts that policies that discourage the consumption of a particular good will induce innovation in a socially desirable substitute. Evolutionary theory emphasizes the possibility of innovation waves associated with the identification of new dominant designs. We...

This paper surveys the existing literature on diffusion of environmentally beneficial technology. Overall, it confirms many of the lessons of the larger literature on technology diffusion: diffusion often appears slow when viewed from the outside; the flow of information is an important factor in...

The 21st century global decline in productivity growth is not well understood. One possible contributor is a decline in economic dynamism. We explore the contribution of firm formation and employee movement to productivity using administrative data on the population of New Zealand construction...

We explore the use of patent citations to measure the "basicness" and appropriability of inventions. We propose that the basicness of research underlying an invention can be characterized by the nature of the previous patents cited by an invention; that the basicness of research outcomes relates...
