Benjamin Golub’s research [short summary] in economic theory focuses on social and economic networks. A research website, with up-to-date publications and other information, is at http://www.bengolub.net.
His work has examined:
- Learning and gossip: what are the dynamics of information in networks? Who is particularly influential? When do agents learn correctly? When are their beliefs polarized?
- Coordination in organizations: how do strategic agents in complex organizations coordinate, and how do the networks that connect them matter?
- Financial contagion: which financial networks are particularly sensitive to sudden breakdowns?
- Public goods and externalities: in complex favor-trading problems such as pollution reduction, we can use a network perspective to understand how much scope for cooperation there is, who is particularly essential to it, and how to organize negotiations.
