abstract="This paper presents results of an econometric study study of intercity travel demands in Canada, 1961-1976. A translog form of reciprocal indirect utility function is used to test the structure of preferences in five demand sectors: three travel modes, goods and other services. Travel sector preferences are found to be time- and season varying but independent of average weekly work hours. The aggregate results indicate that the demands for all three passenger modes are price-elastic; bus and rail exhibit moderate complementarity, while rail and air are weakly complementary. The most important result derived from our tests of separability was that the demand system for the three passenger modes is inextricably tied to the rest of the economy, and therefore, may not be studied in isolation from the goods and other services sectors.<p /><p>Language: en</p>",
