We analyze the phenomenon of hub dominance by developing a model relating fares to distance, using the main leg of intercontinental flights for scaling purposes. Our results indicate that at least some of the major European carriers place a mark up on flights originating from or going to their...

This paper analyzes the relative economic power position of home carriers in hub-and-spoke systems. Hub-and-spoke systems may lower costs on densely traveled routes and enable economically viable operations on less densely traveled routes. The reverse side is probably that carriers enjoy...

This paper presents a framework for analysing spatial aspects of environmental policies in the regulation of trans-boundary externalities. A spatial price equilibrium model for two regions is constructed, where interactions between these regions can occur via trade and transport, via mutual...
