An approximation to technical efficiency in Spanish toll roads through a DEA approach

Abstract

This research has an academic approach is to know the relative efficiency of toll roads managed by the Administración General del Estado through a DEA approach. The global technical efficiency, local pure technical efficiency and scale efficiency were estimated. Thus, the possible reasons why there is inefficiency and as reverse it. The great majority of toll roads are not fully effective according to the DEA approach, showing a greater global efficiency, with an increase in their return to scale, with the possibility of improvements in their efficiency levels.
