Tiivistelmä: | This study aims to estimate road freight demand in the UK for the period 1956-2003 and to determine the occurrence of decoupling between economic activity and freight demand as elaborated on McKinnon (2006). As models with a deterministic trend cannot accommodate a long-run relation between the variables in the freight demand, one needs to model a relationship between the growth rates instead of the levels of the variables. Models with a stochastic trend led to better results and confirmed that the pace decoupling during the final years of the sample period increased. Price and income elasticities were approximated to be about 18 per cent and 65 per cent, respectively. |
