“…The first novelty is methodological, as we illustrate the advantages of a cointegrating approach applied on a system of fuel shares, which has been previously applied only once but for the industrial sector as a whole rather than the industrial subsectors modelled in the study. By implementing the first cointegration analysis for a set of fuels shares estimated at a disaggregated industrial level, we showed that plausible and robust estimates of price elasticities can be obtained Bardazzi et al (2016) -0.82 Italy Burke and Yang (2016) (-1.09, -1.00) International Enevoldsen et al 2007-0.11 Nordic countries Harvey and Marshall (1991) -0.62 UK Huntington (2007) (-0.29, -0.15) US Hyland and Haller 2018-1.16 Ireland Pindyck (1979) -1.44 UK Renou-Maissant (1999) -0.65 UK Serletis et al 2010-0.13 UK Serletis and Shahmoradi (2008) (-1.50, -1.01) US Steinbuks 2012(-0.94, -0.28) Long-run, UK, heating and all processes respectively Suh 2016-0.20 US Taheri and Stevenson (2002) -0.39 US Uri (1979) -082 UK Uri (1982) -0.91 UK Westoby (1984) -1.06 UK Our weighted average -1.22 UK Enevoldsen et al (2007) (-0.28, -0.10) Nordic countries Harvey and Marshall (1991) -0.06 UK Hyland and Haller (2018) -0.31 Ireland Jamil and Ahmad (2011) -1.22 Long-run, Pakistan Paul et al (2009) -0.40 US Pindyck (1979) -0.56 UK Renou-Maissant (1999) -0.31 UK Ros (2015) (-0.87, -0.52) Long-run, US Serletis et al 2010-0.004 UK Steinbuks (2012) (-1.11, -0.23) Long-run, UK, heating and all processes respectively Suh 2016-0.11 US Taheri and Stevenson (2002) -0.71 US Uri (1979) -0.22 US Uri (1982) -0.50 UK Westoby (1984) -0.39 UK Our weighted average -0.82 UK even from relatively short time series using a parsimonious but careful application of a system approach. Modelling a VECM for each of the eight industrial subsectors we obtained unequivocal evidence for the existence of two cointegrating relationships representing demand for electricity and gas.…”
