It is well known that patent citations occur disproportionately between patents issued to inventors living in the same location, which has been taken as evidence of geographically localized knowledge spillovers. In this study, we find that patent citations also occur disproportionately often in...

A person's schooling years are a formative time for cognitive development, and also a period of intense social interaction and friendship formation. In this paper, we estimate the production of social capital during adolescence and its effect on wages. We develop a model where homophily and...

This paper uses data from global and Canadian surveys data to estimate the powerful linkages between social connections, their related social identities, and subjective well-being. Our explanatory variables include several measures of the extent and frequency of use of social networks, combined...

We explore the links between social capital and labor market networks at the neighborhood level. We harness rich data taken from multiple sources, including matched employer-employee data with which we measure the strength of labor market networks, data on behavior such as voting patterns that...

Using friendship data from Facebook, we study the effects of three aspects of social capital on household financial behavior. We find that the most important measure of social capital in explaining stock market and saving participation is Economic Connectedness, defined as the fraction of one's...

We study how two of the world's largest gangs--MS-13 and 18th Street--affect economic development in El Salvador. We exploit the fact that the emergence of these gangs was the consequence of an exogenous shift in American immigration policy that led to the deportation of gang leaders from the...

We test for evidence of spatial, residence-based labor market networks. Turnover is lower for workers more connected to their neighbors generally and more connected to neighbors of the same race or ethnic group. Both results are consistent with networks producing better job matches, while the...

This paper uses novel, firm-level measures derived from communications metadata before and after a CEO transition in 102 firms to study if CEO turnover impacts employees' communication flows. We find that CEO turnover leads to an initial decrease in intra-firm communication, followed by a...

Using a 40-year panel of all public school teachers and principals in New York State, we explore how female principals affect rates of teacher turnover--an important determinant of school quality. We find that male teachers are about 12% more likely to leave their schools when they work under...

We study CEO turnover - both internal (board driven) and external (through takeover and bankruptcy) - from 1992 to 2005 for a sample of large U.S. companies. Annual CEO turnover is higher than that estimated in previous studies over earlier periods. Turnover is 14.9% from 1992 to 2005, implying...
