Marshallian demands of intercity passenger transport in Spain: 1980–1992. An economic analysis

In this study, a theoretical model for the passenger transport demands in Spain is presented. The data are used for the 1980.I–1992.IV quarterly period, and several equations are estimated for the different modes of transport: railway (Talgo), railway (long distance); road and air transport. Cointegration techniques, which are subject to a wide range of contrasts, are used to obtain short and long term equations. The product, price and cross-elasticities of each mode of transport are obtained. These estimations may be used to analyse the effects of transport tariffs on income changes, as well as to predict short- and long-term traffics.
