In Silicon Valley's computer cluster, skilled employees are reported to move rapidly between competing firms. This job-hopping facilitates the reallocation of resources towards firms with superior innovations, but it also creates human capital externalities that reduce incentives to invest in...

This paper investigates how physical, organisational, institutional, cognitive, social, and ethnic proximities between inventors shape their collaboration decisions. Using a new panel of UK inventors and a novel identification strategy, this paper systematically explores the net effects of all...

Due to the growth in international migration in recent decades, the workforce of firms in host countries has become considerably more diverse, both demographically and culturally. It is an important question for firms and for governments to ask whether there are some productivity-enhancing...

To investigate econometrically whether cultural diversity of a firm's employees boosts innovation, we create a unique linked employer-employee dataset that combines data from two innovation surveys in The Netherlands with administrative and tax data. We calculate three distinct measures of...

To investigate econometrically whether cultural diversity of a firm's employees boosts innovation, we create a unique linked employer‐employee dataset that combines data from two innovation surveys in The Netherlands with administrative and tax data. We calculate three distinct measures of...

This paper examines the effects of foreign- and native-born STEM graduates and non-STEM graduates on patent intensity in U.S. metropolitan areas. I find that both native and foreign-born STEM graduates significantly increase metropolitan area patent intensity, but college graduates in non-STEM...

In this paper, we argue that the size and the composition of the female migrant population in a given area can affect the marital stability of natives. We take Italy as a case-study and we offer discrete-time event history models predicting marital disruption on data from the nationally –...
