| Abstract: | This paper estimates the effect of research externalities in generating innovation. R&D and patent data are used for European Regions in the 19771995 period. It is found that spillovers are very localized and exist only within a distance of 300 km. The estimates are robust to simultaneity, omitted variable bias, different specifications of distance functions, country and border effects. However the size of these spillovers is small. Doubling R&D spending in a region would increase the output of new ideas in other regions within 300 km only by 23 percent, while it would increase the innovation of the region itself by 8090 percent. |
