Why the TRAIL+?

The TRAIL+ is an advanced master’s programme in Trade and Investment Law combined with courses in international law and economics. This programme is offered at the World Trade Institute in cooperation with the Faculty of Law of the University of Bern. The programme includes more law courses and fewer courses on economics than the MILE programme. Upon the successful conclusion of the TRAIL+ programme, the student is awarded an LL.M. in International Trade and Investment Law, as well as a Diploma of Advanced Studies (DAS) in International Law and Economics.
