【 摘 要 】

Cargo handling in ports is a multioutputactivity, as freight can arrive in many forms such ascontainers, bulk, rolling stock, or noncontainerized generalcargo. In this paper Tovar, Jara-D�, and Trujillo analyzethe operation of port terminals through the estimation of amultioutput cost model that uses monthly data on three firmslocated at the Las Palmas port in Spain. This permits thecalculation of product-specific marginal costs, economies ofscale (general and by firm), and economies of scope, whichare key tools to help the regulators in their task.
