We compare the geographic location of patent citations to those of the cited patents, as evidence of the extent to which knowledge spillovers are geographically localized. We find that citations to U.S. patents are more likely to come from the U.S., and more likely to come from the same state...

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...

The israeli high tech sector is widely regarded as a hotbed of cutting-edge technologies, and as the growth engine of the israeli economy in the nineties and beyond. In this paper we present a close-up portrait of innovation in Israel for the past 30 years, with the aid of highly detailed patent...

The goal of this paper is to provide an overview of R&D policy in Israel, and critically examine the policies currently in place as well as proposals to change them. We review in Part I the various programs of the Office of the Chief Scientist (OCS) of the Ministry of Industry and Trade in...

This paper presents evidence that firms' patents, profits and market value are systematically related to the"technological position" of firms' research programs. Further, firms are seen to "move" in technology space in response to the pattern of contemporaneous profits at different positions....

This paper uses sales and patent distribution data to establish the market and technological "positions" of firms. A notion of technological proximity of firms is developed in order to quantify potential R&D spillovers. The importance of the position variables and the potential spilover pool in...
