Purpose The Spanish airport system contains several regional airports within an amenity distance and alternative travel modes. Profitable cross-subsidise small airports, which are not required for development or connectivity. Airports government-owned centralised-managed by Air Navigation (AENA, its acronym). This study aims to analyse the probability of under-used public infrastructure AENA’s ...

Both are central to allowing people to perform at their capabilities. Both are often provided by, or subsidized by, government. Heterogeneity— the idea that interventions such as AP classes or bypass surgery may have differ...

An issue that has received little attention in the Data Envelopment Analysis literature is the decomposition of profit inefficiency by means of measures that account all sources of technical inefficiency. In this paper we introduce a new way to measure and decompose profit inefficiency through weighted additive models. All our results are derived from a new FenchelMahler inequality using dualit...

We study the problem of optimizing traffic in decentralized transportation networks, where the cost of a link depends on its congestion. If users of a transportation network are permitted to choose their own routes, they generally try to minimize their personal travel time. In the absence of centralized coordination, such a behavior can be inefficient for society and even for each individual us...

We examine the cost structure of public schools in this paper, using frontier cost models that enable us to estimate sources of inefficiency. A two equation stochastic frontier model is presented that can be used to explain both cost and the sources of inefficiency. Using that model and data for public schools in Nebraska over the period 1989-92, we estimate cost frontiers for the districts. Es...
