2.6. Implications for Public Policy


In this study, observations were made using disaggregate data on a sample of 62 markets that cover a broad range of market structures. Some of the most important points that were shown include the following:

  • Low price dispersion can be associated with both low and high market concentration, depending on the characteristics of the market. This finding contrasts with the findings of past research on price dispersion.

  • When a low cost carrier is the only airline competing nonstop on a route, the monopoly route functions differently than a monopoly with a major carrier. Even in a monopoly situation, low cost carriers (especially Southwest) demonstrate flat pricing and price dispersion as the day of departure approaches.

  • As the day of departure approaches, price dispersion can either increase or decrease.

  • Peak and off-peak periods often demonstrate different pricing strategies, highlighting the importance of jointly examining price and demand.

  • Major carriers tend to exhibit more dynamic pricing strategies than those of low cost carriers, suggesting the former are targeting both business and leisure customers.

  • Markets with codeshares (specifically codeshares between US and UA) sometimes exhibit unusually high price dispersion on the airline that is selling tickets for a flight operated by another airline.

The results of this study could be used to support analysis of mergers and acquisitions, allocation of gate slots for new entrants, and other policies that relate to airline competition and the assessment of consumer welfare benefits. For example, this paper has shown that there are certain instances when monopoly routes exhibit lower price dispersion and lower average prices than competitive routes, as is the case of monopoly routes with one nonstop low cost carrier. These differences in monopoly routes highlight the importance of understanding price dispersion at the detailed, disaggregate level when analyzing the impact of future mergers and acquisitions.

Perhaps most importantly from a public policy perspective, this paper shows the importance of disaggregate data that describe individual airline behavior. Much public policy discussion and analysis relies on average market values that can hide important market behavior. With the advent of internet-based ticketing, a powerful tool now exists that can be used to understand some of the finer detail of airline markets and competition.



2.7. Future Research


In future research efforts, there is a need for disaggregate demand data in order to link pricing strategies with demand as the day of departure approaches. This could be accomplished by pulling seat maps off of the internet while collecting airfares online. There is also an obvious need for more research, at the disaggregate level, on how codesharing affects pricing within a market. As more and more airlines begin to use codeshares, understanding the impacts on the market will become more important. There is also a need to link price dispersion to individual revenue management practices of airlines, as there appears to be evidence of more price dispersion in airlines with complex revenue management systems. Additionally, in future research efforts, it would be helpful to compare the offered ticket observations with an actual ticket sample to see which fares were actually purchased. In doing this, market sizes, carrier shares and average fares for each carrier could also be obtained from the ticket sample.
