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...

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...

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...

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

An inventor's own knowledge is a key input in the innovation process. This knowledge can be built by interacting with and learning from others. This paper uses a new large-scale panel dataset on European inventors matched to their employers and patents. We document key empirical facts on...

Based on an original dataset linking patent data and biographical information for a large sample of US immigrant inventors with Indian names and surnames, specialized in ICT technologies, we investigate the rate and determinants of return migration. For each individual in the dataset, we both...
