We examine the relation between the social ties between firms' headquarters locations and co-movements between their fundamentals and stock returns. Our evidence indicates that firms in the same industry with socially connected locations exhibit co-movement in fundamentals and stock returns that...

Social networks are a key factor of success in life, but they are also strongly segmented on gender, ethnicity, and other demographic characteristics (Jackson, 2010). We present novel evidence on an understudied source of homophily: behavioral traits. Behavioral traits are important determinants...

We present a dynamic model of social network formation in which a fixed number of agents interact in overlapping social groups. We derive several results on the formation of links in such networks, including results on the degree distribution, on comparative statics relating degree and group...

We analyze the characteristics of the social networks of students studying in the economics department in one Russian university. We focus on student friendship and study assistance ties and demonstrate how these networks are connected with the individual characteristics of students and their...

It is important to consider the interweaving nature of online and offline social networks when we examine social network evolution. However, it is difficult to find any research that examines the process of social tie formation from an integrated perspective. In our study, we quantitatively...

I investigate introductions as a way of network formation. In the model, players are endowed with different ability levels and want to match with a neighbour as capable as possible. Introductions for unacquainted neighbours influence the matching outcome since the network structure is changed. I...

We provide an overview and synthesis of the literatures analyzing games in which players are connected via a network structure. We discuss, in particular, the impact of the structure of the network on individuals’ behaviors. We focus on game theoretic modeling, but also include some discussion...

We choose between alternatives without being fully informed about the rewards from different courses of action. In making our decisions, we use our own past experience and the experience of others. So the ways in which we interact - our social network - can influence our choices. These choices...
