In this paper, we analyze efficiency and productivity of Italian and Portuguese airports, by using the directional distance function and the Luenberger productivity indicator. The key advantage of this approach is that both input contraction and output expansion are considered. The model generates efficiency scores, ranking the airports in the sample. We conclude that inputs and outputs play a major role in airports efficiency. According to this methodology, it can be stated that some Italian and Portuguese airports are efficient and that productivity increased in most of the cases.
