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 is 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. (C) 1997 Elsevier Science Ltd.
