Title: Networks as covers
Description: This paper proposes that networks give actors a cover by giving them the excuse of sociability to engage in normatively prohibited market behaviors. I apply this hypothesis to actors in long-term exclusive relationships who are surreptitiously seeking new relationships without jeopardizing their current ones. I hypothesize that these actors will be drawn to social environments where others socialize with their friends, and that they will establish numerous relationships in these environments to cover up their real intent. I find significant support for these predictions using data from a large on-line social network.
