A Rentabilidade da TAM no Contexto de Elevação do Preço do Barril de Petróleo
Abstract
The present study aims at evaluating the extent to which the international increase in petroleum price per barrel impacted the profitability of the Transportes Aéreos Marília S.A. (TAM airlines). The context of civil aviation is explored in the case study methodology, including DuPont Method and simple linear regression for the 2001-2006 period. The study attempts to falsify the hypothesis of no relationship between the increase in petroleum price per barrel and profitability. Apparently, the price of a barrel of petroleum influences TAM¿s ROA, ROE, Cost of Assets and Services, Operational Budget, and Net Profit, especially on quarterly bases (significance level: p < .05).
