This paper examines the trends in geographic localization of knowledge spillovers via patent citations, considering US patents from the period of 1976-2015.

We want to understand how important market frictions are in stifling the transmission of ideas from one firm to another. We use comprehensive data on patent applications from the European Patent Office and a multiple spells duration model to provide estimates that suggest that they are substantial.

We provide evidence on how changes in the use of high-skilled workers (inventors) in a foreign location affect a firm's domestic use of the same type of worker. We exploit rich data that provide variation in the location of inventors within multinational firms across industries and countries to control for confounding firm–time and industry factors. We find that a 10% increase in the use of foreign inventors leads to a 1.9% increase in the use of domestic inventors. Our results suggest that foreign and domestic inventors are complementary in the production of knowledge.

We analyze the effect of patent thickets on entry into technology areas by firms in the UK.

This paper provides a novel portrait of firms engaging in the international use of inventors.

We provide a comprehensive and systematic overview of the Intellectual Property (IP) Box regimes in place in Europe.
