"The Yearbook on International Investment Law & Policy has become an institution in international investment law and policy scholarship. For good reason: it monitors developments in the field and typically comprises an excellent selection of papers from academics, practitioners and policymakers. The fourth and most recent volume is no exception to this rule. The Yearbook is a seminal contribution to the study of the development of internationalinvestment law and policy, and should be on every investment lawyer's essential reading list." --Catharine Titi, Universite Pantheon-Assas Paris II
