A Multioutput Cost Function for Port Terminals : Some Guidelines for Regulation

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-Diacute;az, 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.This paper - a product of the Infrastructure Vice Presidency - is part of a larger effort in the vice presidency to promote analytical work on the economic analysis of the sector
