We assess the role of ethnic ties in the diffusion of technical knowledge by means of a database of patent filed by US-resident inventors of foreign origin, which we identify through name analysis. We consider ten important countries of origin of highly skilled migration to the US, both Asian...

In this paper we review 20 years of quantitative research in the geography of innovation, to whose advancement patent data have contributed in a decisive way. We know now that the importance attributed by the earliest studies to knowledge externalities as an agglomeration force was excessive....

Based on the Knowledge Production Function framework given byGriliches (1979), we slightly modify it so that the innovative output depends upon aset of factors related to the firm internal characteristics and are influenced by the environment.Specifically, regarding the firm internal...
