Equilibrium in the Hotelling model of spatial competition is guaranteed if the distribution of consumers is log concave. In the real world, nothing guarantees such a log concave distribution however, rendering the analytical model unable to provide a primer as to what one might expect from...

We analyze the phenomenon of hub dominance by developing a model relating faresto distance, using the mainleg of intercontinental flights for scaling purposes. Our results indicate thatat least some of the major Europeancarriers place a mark up on flights originating from or going to their hubs.

This paper presents a framework for analysing spatial aspects of environmentalpolicies in the regulation of trans-boundary externalities. A spatial priceequilibrium model for two regions is constructed, where interactions betweenthese regions can occur via trade and transport, via mutual...

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...
