Abstract

The note aims to discuss the methodology applied by the Antitrust Authority for the identification of the relevant market for freight sea transport from/to Sardinia. It is argued that the use of the spatial distance criterion applied to arbitrary couples of origin and destination locations leads to biased results if other determinants of port choice are excluded from the analysis. Furthermore, it is argued in favor of microdata usage to identify preferences of logistics operators (the final users) and hence to estimate the demand schedule.
