Abstract
This paper measures the efficiency of Italian airports using Data Envelopment Analysis (DEA). Particularly, the efficiency of an airport is evaluated at three different stages of its cost-revenue production cycle, i.e. cost-operations-revenue stages, while network-slack based measure DEA (NSBM-DEA) is adopted to generate efficiency measurements for the airports at each stage. Results show that the suggested modeling approach has a better discrimination capability than the traditional black-box DEA model and provides important insights for policy makers and airport concessionaires useful for improving industry performance and airport management.
