Foreign Inventors in the US and EU15 : Homophily, Self-selection, and Productivity

Edoardo Ferrucci (Univeristy of Bordeaux) & Francesco Lissoni (Univeristy of Bordeaux), “Foreign Inventors in the US and EU15 : Homophily, Self-selection, and Productivity”

We examined the quality of patent applications signed by US- and EU-resident teams of inventors, as a function of the nationality composition of teams. In particular, we test the hypothesis of a negative association between team’s homophily and patent quality.
