CONSTRUCTION, STABILITY AND PREDICTABILITY OF AN INPUT-OUTPUT TIME-SERIES FOR AUSTRALIA

This paper documents the development of a time series of Australian input-output tables. It describes the construction techniques employed in order to overcome the major issues encountered. Environmentally important processes were delineated using a range of detailed commodity data, thus expanding the original tables from roughly 100 industries into a temporally consistent 344 industries. Data confidentiality and inconsistency were overcome using an iterative constrained optimisation method called KRAS - a recent modification of RAS (Lenzen et al. 2006; 2007; 2009). The article concludes by analysing the stability of input-output coefficients over time similar to work in Dietzenbacher and Hoen (2006). The issue of stability of coefficients and multipliers was investigated under the Leontief and Ghosh models of supply/demand. Finally, the predictability of the models was examined under updated final demand or primary inputs and over varying time scales.
