Cost-efficiency benchmarking of European air navigation service providers

This study uses EUROCONTROL data on operating performance of the national air navigation service providers over the 2002-2011 time period to document in detail the efficiency changes across providers and time using data envelopment analysis. Our results suggest that overall providers' productivity improved over the time period covered by the data, driven by improvements in technical rather than allocative efficiency. However, some trend reversals in the post-2008 crisis period are also observed. © 2015 Elsevier Ltd.
