Maritime competition as an economic phenomenon is currently influenced by a number of factors both at EU and international level. From a legislative point of view, the recent repeal of EC Reg. 4056/1986 affects the treatment of horizontal agreements not only in the liner but also in the bulk sector, which was excluded until recently from the scope of EC secondary competition rules. However, competition distortions are not only a question of private arrangements. They emanate also from measures and practices incompatible with the freedom to provide services, Member states’ protectionism and international mandatory regulation. This volume comparatively and comprehensively examines all these issues, by bringing together contributions from distinguished academics. Particular focus is given on private shipping cartels, the liberalization of cabotage and port services, indirect competition-distorting factors and the latest developments on international regulation of carriage of goods by sea.
