One of MaCCI’s main ambitions is to promote the exchange between lawyers and economists in the field of competition policy. Therefore, two workshops were organized in the end of November this year: the MaCCI Competition and Regulation Day and the ZEW-MPI Workshop on Private Law and Economics. The MaCCI Competition and Regulation Day is an internal event with presentations from MaCCI members working at ZEW and in both the law and the economics department of the University of Mannheim. For the second workshop, the Max-Planck Institute (MPI) for Comparative and International Private Law in Hamburg is an important partner. MaCCI and the MPI have taken turns in hosting the joint workshop now over the course of four years.
