The Austrian Yearbook on International Arbitration 2018 is a collection of articles and essays on current issues and hot topics in commercial and investment arbitration by leading arbitration practitioners. The Yearbook covers a number of areas of both topical and enduring importance which are likely to be of relevance to academics, practitioners or persons who may become involved in arbitration in Austria or in any other place. Some of the articles in the Yearbook analyze significant trends in international arbitration, like the idea of a multilateral investment court, the enforcement of settlement agreements, transparency in international commercial arbitration and in arbitration institutions, arbitration as a mean of private enforcement as well as unilateral arbitration clauses. It also includes the Vienna Repositioning Propositions, a proposal by many experts on how to reposition actors and actions in international arbitrations.
