An efficiency study of airlines and air cargo/passenger divisions: a DEA approach

In this paper we investigate the question of whether a high degree of cargo business improves the operational efficiency of a mixed passenger/cargo airline. We use Data Envelopment Analysis (DEA) to compute the efficiency scores for major airlines in the world and then carry out non-parametric statistical tests. Using data for 29 airlines during the period 1998-2002, we find that airlines with a ...
