This article presents a method of objectively measuring trucking price variations in Canada by constructing price indices. A brief theoretical overview compares the proposed method (that of Tornqvist) with those currently in use. The application of this method to Canadian trucking is then considered in greater detail and compared with the method recently used by M. Boucher as part of a study on Quebec trucking. This comparison illustrates the importance of determining whether a system of revenues or tonne-kilometres will be used for weighting an index, since results differ significantly depending on the system used. Tonne-kilometres weighting appears to underestimate price increases, with respect to Tornqvist's original method, which uses revenues as factors in weighting. The present study also shows an alternative way to obtain series of price indices. This method aggregates the basic series of indices rather than calculating the series from an extensive basic data source. As a result, it enables one to obtain good approximations in respect of a series of price indices based on Tornqvist's original method.
