In 2010 China was the world's fourth largest filer of patent applications. This followed a decade of unprecedented increases in investment in skills and Research and Development. If current trends continue China could rank first in the very near future. We provide evidence that the growth in...

In this paper we use new data to describe how firms from 15 European countries organise their innovative activities. The data matches firm level accounting data with information on the patents that those firms and their subsidiaries have applied for at the European Patents Office. We describe...

How much does US-based R&D benefit other countries and through what mechanisms? We test the 'technology sourcing' hypothesis that foreign research labs located on US soil tap into US R&D spillovers and improve home country productivity. Using panels of UK and US firms matched to patent data we...

We examine the home bias of knowledge spillovers (the idea that knowledge spreads more slowly over international boundaries than within them) as measured by the speed of patent citations. We present econometric evidence that the geographical localization of knowledge spillovers has fallen over...

We examine the “home bias” of knowledge spillovers (the idea that knowledge spreads more slowly over international boundaries than within them) as mea- sured by the speed of patent citations. We present econometric evidence that the geographical localization of knowledge spillovers has...

There is considerable interest in understanding how important market frictions are in stifling the transmission of ideas from one firm to another. Although the theoretical literature emphasizes the importance of these frictions, direct empirical evidence on them is limited. We use comprehensive...
