A multi-output cost function for port terminals : some guidelines for regulation

Abstract

Cargo handling in ports is a multioutput activity, as freight can arrive in many forms such as containers, bulk, rolling stock, or noncontainerized general cargo. In this paper Tovar, Jara-D?, and Trujillo analyze the operation of port terminals through the estimation of a multioutput cost model that uses monthly data on three firms located at the Las Palmas port in Spain. This permits the calculation of product-specific marginal costs, economies of scale (general and by firm), and economies of scope, which are key tools to help the regulators in their task.Economic Theory&Research,Environmental Economics&Policies,Decentralization,Transport and Trade Logistics,Business Environment,Environmental Economics&Policies,Airports and Air Services,Economic Theory&Research,Transport and Trade Logistics,Transport Security
