23.57    The ATEA draws on existing datasets that were not designed for the purpose of an ATEA, and therefore a number of underlying assumptions have been made, which should be considered in interpreting results. These include the following:

  • For each mode of transport, non-transport industries are assumed to exhibit the same input structure and production function of the Division I industry. For example, In-house Road Transport is assumed to have the same structure as that of the Road transport industry in Division I.
  • All economic activity within Division I is assumed to be For-hire transport. No adjustments are made to exclude secondary activity undertaken within that industry that is not related to the provision of transport services.
  • Division I products have not been used as an input to the In-House Transport industry, as it is assumed these activities will be captured within Division I.
  • Extrapolation of the time series from base year data assumes that the relative use of in-house transport products remains constant over time.
