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....

We investigate the causes and consequences of the aging of the scientific workforce. Using novel data on the population of US chemistry faculty members over fifty years, we find that the secular increase in the age of the academic workforce has been mainly driven by the slowdown in faculty...

We investigate whether and how social ties affect performance in teams by implementing a field experiment in which a sample of undergraduate students are randomly assigned to either teams composed by friends or teams composed by individuals not linked by friendship relationships. Students...

We provide some of the first rigorous evidence on performance spillovers and social network in the workplace. The data we use are rather extraordinary - weekly data for rejection rates (proportion of defective output) for all weavers in a firm during a 12 months (April 2003-March 2004) period,...

In this paper we analyze the relationship between social networks and the job search behavior of unemployed individuals. It is believed that networks convey useful information in the job search process such that individuals with larger networks should experience a higher productivity of informal...

Using data from the CPS this paper examines the role of birth-country networks on immigrants' unemployment duration from 2001 to 2013. We find that networks significantly lower unemployment duration for all immigrants. Varying the effect of networks over duration categories we find that networks...

Using detailed data on a cohort of young Americans who were in their late twenties and early thirties in 2008, we investigate the importance of forces different from economic incentives in nest-leaving decisions. We apply recent methods from social network econometrics to identify the importance...

Migration networks are usually captured by the number of people from the migrant's country in the host region. Using Mexican migration data, we analyze the effects of the usual network variable and two additional origin-village-specific variables on migrants' location choice.

If people come to live in a country different from their nation state, due to border shifts, expulsion, or migration, they adopt some of the new country's habits after some time. This paper investigates their (return) migration decision when they have been restricted to live in the foreign...
