This paper studies the diffusion of products and behaviour with coordination effects through social networks when agents are myopic best responders. We develop a new network measure, the contagion threshold, that determines when a p-dominant action – an action that is a best response when...

When preparing a research article, academics engage in informal intellectual collaboration by asking their colleagues for feedback. This collaboration gives rise to a social network between academics. We study whether informal intellectual collaboration with an academic who is more central in...

This paper studies the long-run (stochastic) stability of an evolutionary model with persistent randomness in network games. We focus on evolutionary dynamics in symmetric coordination games where players choose the best responses to their opponents' strategies. Recent studies find that the...

This study is the first to examine the role of discussants in academic knowledge production. Comparing articles of similar quality with andwithout discussants,we find that having a discussant increases a paper's probability of publication in prestigious journals, but not its citation count....
