Please join us for a discussion with Mathew McCubbins, Provost Professor of Business, Law and Political Economy at the University of Southern California, entitled "Good Edge, Bad Edge: Connectivity, Constraint and Coordination in Networks."

Professor McCubbins writes:

Coordination is a core problem in social situations. Tasks as diverse as trying to decide where to go to dinner, what political candidate to support or which regulatory policy to adopt all require coordination. Information is often the key to solving coordination problems, and this information can be modeled as a network that connects individuals to each other. In this paper we show that these connections can both improve and impede a group's ability to achieve coordination. To model how networks influence coordination we distinguish between "constraining edges"that make coordination harder by reducing the number of solutions, and "redundant edges" that make coordination easier by increasing communication without affecting the number of solutions. We show experimentally that the addition of constraining edges reduces coordination, while redundant edges improve subjects' ability to solve a coordination problem.
