Friendship formation is of central importance to online social network sites and to society, but can suffer from significant and unequal frictions. In this study, we demonstrate that social networks and policy makers may use an IT-facilitated intervention – displaying things in common (TIC) between users (mutual hometown, interest, education, work, city) – to encourage friendship formation, especially among people who are different from each other. Displaying TIC may update an individual’s… 

From Strangers to Friends: Tie Formations and Online Activities in an Evolving Social Network

In contrast to results for static networks, it is found that seeding to users with the most friends is not the most effective strategy to increase users' activity levels in an evolving network.

Individualized conditional independence testing under model-X with heterogeneous samples and interactions

Model-X knockoffs and the conditional randomization test are methods that search for conditional associations in large data sets, controlling the type-I errors if the joint distribution of the

Do Your Online Friends Make You Pay? A Randomized Field Experiment on Peer Influence in Online Social Networks - Online E-Companion Appendix

This paper presents a novel randomized experiment that tests the existence of causal peer influence in the general population -- one that did not involve subject recruitment for experimentation -- of a particular large-scale online social network, utilizing a unique social feature to exogenously induce adoption of a paid service amongst a group of randomly selected users.

Tie Strength, Embeddedness, and Social Influence: A Large-Scale Networked Experiment

This work presents some of the first large-scale in vivo experimental evidence investigating the social and structural moderators of peer influence in networks, and finds that both embeddedness and tie strength increase influence.

Socially Nudged: A Quasi-Experimental Study of Friends' Social Influence in Online Product Ratings

It is found that rating similarity between friends is significantly higher after the formation of the friend relationship, indicating that with social-networking functions, online rating contributors are socially nudged when giving their ratings.

How Do Friendships Form?

We examine how people form social networks among their peers. We use a unique dataset that tells us the volume of email between any two people in the sample. The data are from students and recent

An Economic Model of Friendship: Homophily, Minorities and Segregation

We develop a model of friendship formation that sheds light on segregation patterns observed in social and economic networks. Individuals come in different types and have type-dependent benefits from

The Evolution of Influence Through Endogenous Link Formation

The study investigates the endogenous acquisition of network position as a function of exogenous individual characteristics and finds that independents can have less influence out-degree than imitators who collect information from multiple sources.

Social Ties and User Generated Content: Evidence from an Online Social Network

We use variation in wind speeds at surfing locations in Switzerland as exogenous shifters of users' propensity to post content about their surfing activity onto an online social network. We exploit

Who Should I Follow? Recommending People in Directed Social Networks

It is found that sharing an audience with someone is a surprisingly compelling reason to follow them, and that similarity is much less persuasive.

A Structural Model of Network Dynamics: Tie Formation, Product Adoption, and Content Generation

We develop a structural model for the co-evolution of individuals’ friendship tie formations and their concurrent online activities (product adoptions and production of user-generated content) within
