This paper has two objectives. First, it describes a new database mapping migratory patterns of inventors, extracted from information included in patent applications filed under the Patent Cooperation Treaty. We explain in detail the information contained in the database and discuss the...

The goal of this paper is to assess the influence of spatial mobility of knowledge workers on the formation of ties of scientific and industrial collaboration across European regions. Co-location has been traditionally invoked to ease formal collaboration between individuals and firms, since tie...

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...

The aim of the present paper is to shed light on the determinants of geographical mobility and location choices of skilled individuals across the European regions. The most talented workers, e.g. inventors, move for a number of reasons, contributing in this manner to the geographical diffusion...

This paper documents the influence of diaspora networks of highly-skilled individuals – i.e., inventors – on international technological collaborations. Using gravity models, it studies the determinants of the internationalization of inventive activity between a group of...

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....

This paper documents the influence of diaspora netw orks of highly-skilled individuals – i.e.,inventors – on international technological collaborations. Using gravity models, it studies the determinants of the internationalization of inventive activity between a group of industrialized...

We investigate the importance of the labour mobility of inventors, as well as the scale, extent and density of their collaborative research networks, for regional innovation outcomes. To do so, we apply a knowledge production function framework at the regional level and include inventors’...
