This paper characterizes the equilibria in airline networks and their welfare implications in an unregulated environment. Competing airlines may adopt either fully-connected (FC) or hub-and-spoke (HS) network structures; and passengers exhibiting low brand loyalty to their preferred carrier...

This paper presents a simple model of airline schedule competition that circumvents the complexities of the spatial approach used in earlier papers. Consumers choose between two duopoly carriers, each of which has evenly spaced flights, by comparing the combinations of fare and expected schedule...

Hub congestion is a major concern and a relevant policy issue because it causes important problems at airports such as flight delays, cancellations and missed connections that end up affecting both air travelers and airlines. We address the interplay between flight frequency and aircraft size in...

This paper presents a simple model of airline schedule competition that circumvents the complexities of the spatial approach used in earlier papers. Consumers choose between two duopoly carriers, each of which has evenly spaced flights, by comparing the combinations of fare and expected schedule...

This paper looks at the endogenous formation of airline alliances by means of a two-stage game where first airlines decide whether to form an alliance and then fares are determined. The authors analyse the effects and the strategic formation of airline alliances when two complementary alliances,...

We analyze the effect of research joint ventures (RJVs) on consumer welfare in an international context when collusion can occur. Our results suggest that antitrust authorities should distinguish between domestic and international RJVs and be more benevolent with international RJVs.

Airports have become platforms that derive revenues from both aeronautical and commercial activities. The demand for these services is characterized by a one-way complementarity in that only air travelers can purchase retail goods at the airport terminals. We analyze a model of optimal airport...

This article provides a rationale for the present trend towards complementary airline alliance formation, by studying the strategic behaviour of carriers that may decide whether to form an alliance (that may be either parallel or complementary) or stay alone.

The market developments in international air transportation have led to the dominance of three global airline alliances - Star, SkyTeam and oneworld. At the same time, members of these alliances receive increasingly more freedom in coordinating various aspects of joint operations, including...
