The Impacts of Liberalization on Competition on an Air Shuttle Market Alessandro V. M. Oliveira§ Abstract This paper aims at assessing the impacts of deregulation on the most important airline market in Brazil: the air shuttle Rio de Janeiro – São Paulo. By making use of both a two-stages budgeting representation of the demand system, and a competition model with product heterogeneity among rivals, and based on the framework of the New Empirical Industrial Organization (NEIO), it was possible to infer whether a structural change on airlines' conduct parameters due to liberalization was observed. This exercise ultimately served as a test of the efficacy of the policy employed by the regulators since 1998. The main conclusions were that regulatory reform effectively stimulated firms to significantly increase the degree of competition in the market (via a decrease in market power), and that marginal-cost or even below-marginal-cost pricing was not rejected for some airlines.

Introduction This paper aims at developing an empirical model for assessing the impacts of economic liberalization on competition in a relevant subset of the Brazilian airline industry: the air shuttle service on the route Rio de Janeiro - São Paulo. In this market the first air shuttle in the world, the ‘Ponte Aérea’, was created in 1959, by an agreement of airline managers, and had a dominant position in the airport-pair linking both city centers for almost forty years.
