Bonding and Bridging Social Capital and Economic Growth

In this paper we develop a formal model of economic growth and two types of social capital. Following extant literature, we model social capital as participation in two types of social networks: first, closed networks of family and friends, and, second, open networks that bridge different communities. Higher levels of social capital may crowd out economic growth through a reduction of working time. At the same time, participation in intercommunity networks reduces incentives for rent seeking and cheating, promoting economic growth. We test our hypotheses in a sample of European regions using unique data from the European Value Studies (EVS). Our findings show that it is important to distinguish between the nature of the social interaction.
