Econometric estimation of scale and scope economies within the port sector: a review

Seaports provide multiple services to ships, cargo and passengers. The size of the port and type of service they offer are two key elements when deciding whether competition is feasible and how to promote it or, conversely, regulation is needed. Analysing this requires a profound knowledge of the cost structure of the activity involved. This means not only knowing total costs for different volumes of aggregated traffic, but also the behaviour of costs when part of the bundle is produced, i.e. when the mix changes. The optimal organization of the industry can be studied by means of cost and production functions. This paper offers a review of the relatively scarce literature about econometric ports’ cost structure, and highlights the role of the multioutput approach as the correct one because it allows the calculation of key cost indicators (economies of scale, scope and so forth) to determine the optimal port industrial structure for a given forecast of demand (traffic mix and volume).
