Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive-based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs....

This paper utilizes the bootstrap to construct tests using the measures for goodness-of-fit for nonnested regression models. The bootstrap enables us to compute the statistical significance of the differences in the measures and to formally test on nonnested regression models. The bootstrap...

In this paper we use a two stage procedure, based on bias corrected DEA, to evaluate the impacts of regulatory reforms on technical efficiency of 28 Italian airports during the period 2000–2006. We employ two different DEA models: physical and monetary. The first relies on the aeronautical...

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...

Over the past twenty years, important changes in the Italian health system have led to different approaches in organizing, delivering and financing health services throughout the regions of the country. This study aims to examine the impact these factors have had on efficiency. The methodology...
