Productivity change in Italian airports

Abstract

This paper examines the total factor productivity of 28 Italian airports during 2000–2006 using non-parametric estimation methods. Moreover, non-parametric inference and hypothesis test on the Malmquist index and its two main components, efficiency and technological change, have been carried out. All the airports have been characterized by technological regress and only a minority of airports experienced an increase in productivity lead by the improvement of efficiency.Airport efficiency; bootstrap; Malmquist index; DEA
