A re-examination of incumbents' response to the threat of entry: Evidence from the airline industry

Much of the literature on the airline industry identifies a potential entrant to a market based on whether the relevant carrier has presence in at least one of the endpoint airports of the market without actually operating between the endpoints. Furthermore, a potential entrant is often defined as a credible entry threat to market incumbents once the potential entrant establishes presence at the second endpoint airport of the market. This paper provides evidence that even when a potential entrant has presence at both endpoint airports of a market, incumbents may not respond to this as an effective entry threat. Specifically, we find that (1) incumbents lower price by more when the potential entrant has a hub at one or both market endpoints; and (2) incumbents increase rather than lower their price if they have an alliance partnership with the potential entrant.
