Derived demands for ‘General Cargo’ shipping in Spain, 1975–1992, an economic approach

Abstract

The behaviour of ‘General Cargo’ shipping transport in Spain is analysed.Derived demands for the period 1975–1992 are estimated. Cointegration techniques are used to obtain long-run and short-run equations, both estimated separately in two steps, and jointly in one step. Price and output elasticities agree with previous findings and could be used for analyzing the revenue effects of changes in freights and medium-term forecasting of traffic and revenues.
