Abstract
Port authorities (PAs) generate revenues by guiding, coordinating and exploiting their resources, facilities and infrastructure of their ports. In this article, using Data Envelopment Analysis (DEA), we assess and analyze the efficiency of PAs in generating revenues. Despite the plethora of studies on port efficiency, there has been no study to focus on PAs and compare, in terms of efficiency, their revenue generation mechanism. For that purpose, we present two different modeling approaches: one that relates revenues to the basic throughput and activity of the port and another that takes into consideration land, infrastructure and labor indicators. For the implementation of this approach we use a sample set of international landlord, multi-activity ports. The analysis first discriminates between efficient and non-efficient ports and for the latter it identifies their benchmarks and provides target values for their revenues. Furthermore, in a post-DEA stage the article examines the relation between efficiency and the size of a port.
