Determinantes de guerra de pre？os e conluio no transporte aéreo brasileiro

this paper aims to identify possible patterns of price wars and the formation of collusion by the airlines that operate in the route rio de janeiro - s？o paulo (tam and gol) and estimate the conditions that facilitated the two phenomena in the period 2002 - 2010. to this end, we used game theory, economic theory of cartels and logit models as analytical tools. the results show that the determinants of these two phenomena are different for each airline: tam had a higher probability of collusion formation than gol in the analyzed period, while the latter was more likely to enter a price war than in collusion. furthermore, the variables used in this study could not explain the probability of tam practice price war.
