In most multi-species fisheries managed through output controls, total allowable catches (TACs) are set primarily on the basis of biological considerations, usually on a species by species basis. An implicit assumption of management is that fishers are able to adjust their product mix in line...

This paper deals with risk and uncertainties that are an inherent part of designing and implementing fisheries rebuilding plans. Such risk and uncertainties stem from a variety of sources, biological, economic and/or political factors, and are influenced by external factors like changing...

Production condition and behavioural reactions have traditionally been modelled in unregulated industries. The paper examines the impact that output regulation will have in an industry of multiple outputs where production of regulated and unregulated outputs are combined. The industry's respond...

A purpose of this paper is to give a critical review of the total allowable catch (TAC) policy within the European Union (the EU) for cod in the North Sea. The actual TACs are compared with the biological recommendations about the TAC and the bio-economic optimal TAC. It is shown that the actual...

The paper analyses the perspectives for a new container port at the German North Sea coast. In view of the expected further enlargement of container ship sizes and sustained growth in international trade, the port seems to be an economically sound project. Public funds, however, will probably...

Russische Schiffe sind seit einigen Jahren damit beschäftigt, kritische Infrastruktur in den Gewässern rund um Europa auszukundschaften. Dieses "Mapping" dient offenbar der Vorbereitung möglicher Sabotageakte und stellt somit eine erhebliche Sicherheitsbedrohung dar. Nach internationalem...

Since the 1990s, efficiency and benchmarking analysis has increasingly been used in network utilities research and regulation. A recurrent concern is the effect of environmental factors that are beyond the influence of firms (observable heterogeneity) and factors that are not identifiable...
