Over the next few days, we will be hosting a discussion of Sergio Puig’s article Social Capital in the Arbitration Market, which was published in volume 25, no. 2 of the European Journal of International Law (2014). Sergio is an Associate Professor of Law at the University of Arizona James E. Rogers College of Law. The commentaries on his article will be by Daphna Kapeliuk (Radzyner Law School, IDC Herzliya), Thomas Schultz (King’s College London), and Michael Waibel (Cambridge). We are grateful to all of them for participating in the discussion.
