%0 Journal Article %T Merger Simulation with Quality Improvement: Application to the Case of a Codeshare between Major Carriers in Brazil %A Mois¨¦s Vassallo %J Revista de Literatura dos Transportes %D 2010 %I %X This work presents a model of simulated post-mergers prices adjusted to the specificities of airlines industry. The model here proposed takes in consideration peculiar characteristics of this sector, in order to measure the effect in prices due to improvements of quality in the product after the merger. With this development, a strong hypothesis of the traditional post-merged prices simulation models was relaxed. Constant quality before and after mergers is the hypothesis relaxed, this hypothesis is typical of the models implemented in other sectors. Due to air transportation specificities it was possible to develop a model able to measure the quality improvement effects in the post-merge prices.[Paper in Portuguese] %K codesharing %K mergers %K alliances %K antitrust %K air transportation %U http://www.pesquisaemtransportes.net.br/relit/index.php/relit/article/view/63
