For a cross-section of 123 European regions, we find evidence for a positive effect of generalized trust on regional innovation activity. We aim to identify causal effects by using instrumental variables from climate and soil data, drawing from recent literature on the effects of climate on...

We find that social capital in U.S. counties, as captured by strength of social norms and density of social networks, is positively associated with innovation of firms headquartered in the county, as captured by patents and citations. This relation is robust in fixed-effect regressions,...

For a cross-section of 123 European regions, a positive causal effect of generalised trust on innovation activity is identified using a set of geographic instrumental variables from climate and soil data. The geographic instrumental variables are defined and discussed. The popular explanation...

This paper investigates the interplay between social capital, innovation and economic growth in the European Union. We identify innovation as an important mechanism that transforms social capital into economic growth. In an empirical investigation of 102 European regions in the period 1990-2002,...

This research investigates the role of social capital and government intervention in explaining the differences of innovation output and economic growth for regions of the European Union from 1990-2002. Using several measures of social capital and innovation, and the European Union’s Objective...

We study whether interactions between individuals with different skills, expertise and perspectives influenced innovation in U.S. counties from 1850 to 1940. We introduce and validate a new measure of social interactional diversity based on the distribution of surnames: lower surname diversity...

This paper analyzes the structural dimension of social capital, and its impact on the success of open source software projects. By examining ties existing between open source projects through their core members altogether with other contributors, we identify the communication paths and flows of...
