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...

We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can maximize it. Through the links in the collaboration network, researchers create spillovers not only to their direct coauthors but also to researchers indirectly linked to them....

This paper discusses the determinants of product innovation in young innovative companies (YICs) by looking at in-house and external R&D and at the acquisition of external technology in embodied and disembodied components. These input-output relationships are tested on a sample of innovative...

Academic entrepreneurship has become an increasingly important channel through which universities contribute to economic development. This paper studies academic entrepreneurs using a comprehensive venture capital database. I find that about two-thirds of the academic entrepreneurs locate their...

We study entrepreneurs' start-up financing from banks and local financiers. An informal network, whose membership cannot be observed by outsiders, conveys the good signals it gets about the hidden types of network entrepreneurs to local financiers, which are then reflected in different loan...

In virtually all industrialized countries, women are underrepresented in entrepreneurship, and the gender gap exhibits a remarkable persistence. We examine one particular source of persistence, namely the prevalence of gendered networks and associated peer effects. We study how early career...

This paper analyzes the role of networks in access of women entrepreneurs to start-up capital and firm performance in Eswatini, a country with one of the highest female unemployment rates in Africa. The paper first shows that higher initial capital is associated with better sales performance for...

In nationally representative household data from the 2008 wave of the Rural to Urban Migration in China survey, nearly two thirds of rural-urban migrants found their employment through family members, relatives, friends or acquaintances. This paper investigates why the use of social network to...

When one's treatment status affects the outcomes of others, experimental data are not sufficient to identify a treatment causal impact. In order to account for peer effects in program response, we use a social network model. We estimate and validate the model on experimental data collected for...

We contribute to the literature on relative age effects on pupils' (non-cognitive) skills formation by studying students' social network. We investigate data on European adolescents from the Health Behaviour in School Aged Children survey and use an instrumental variables approach to account for...
