This book bundles the papers of the Fortis Bank Chair lectures 2001-2003 on two major sectors of the economy in the European Union. The first series of lectures is devoted to financial services and financial markets in transition. The subjects dealt with in the papers include the relationship between the freedoms in the EC treaty and private international law, financial regulation and supervision of banks, the international insurance market and the Euro in the new member states. The second part focuses on interesting developments in European transport policy: rail, maritime and multimodal transport and air transport. It is complemented by a paper on tax law as an instrument to integrate environment and energy considerations in EC transport policy.
