Economy-wide assessment<br />
What are the economy wide implications of the changes foreshadowed in<br />
the previous Cha<strong>pt</strong>er? This Cha<strong>pt</strong>er reports on MONASH model<br />
simulations about the impact of greater use of e-commerce in the<br />
Australian economy. It compares outcomes for a range of economic<br />
indicators against a base case forecast which represents outcomes with less<br />
use of e-commerce.<br />
4.1 The base case<br />
The simulation results that follow compare the expected outcomes with<br />
greater use of e-commerce against those that would have been obtained<br />
anyway, if use of e-commerce stayed largely static (the base case). The<br />
base case simulation is detailed in Appendix C to this report. The key<br />
inputs of the base case are:<br />
• The economy will grow and exhibit changes in prices and industry<br />
composition in line with standard economic forecasts (incorporating<br />
forecasts from Access Economics).<br />
• Trends in world commodity prices (largely drawing on Australian<br />
Bureau of Agricultural and Resource Economics forecasts).<br />
• Trends in technology particularly as reflected in changes in inputoutput<br />
ratios for differing industries.<br />
• Known policy changes of significance including issues such as the<br />
introduction of the GST and related reforms are included. 13 The Ralph<br />
reforms have not been included because they were announced after<br />
this analysis had been done.<br />
• Immigration and population growth forecasts from the ABS.<br />
• Pre-existing trends in the use of e-commerce as they applied up to the<br />
end of 1996–97 (the base year for the current MONASH model).<br />
This is projected to be supported by a reasonable level of access to<br />
the Internet infrastructure through adequate bandwidth at<br />
reasonable prices.<br />
• The economic impacts of greater use of some forms of e-commerce<br />
such as EDI and ATMs and EFTPOS are included in this study. It is<br />
viewed that these developments continue well established trends,<br />
further developments are likely to happen anyway and they have been<br />
factored in to the forecasts about expected economic outcomes.<br />
Against these settings, the results which are discussed below can therefore<br />
be viewed as the sensitivity of each economic indicator (i.e. output,<br />
employment, etc.) to greater use of e-commerce.<br />
4.2 Change scenario<br />
To evaluate the economy-wide implications of e-commerce, the analysis<br />
draws on 14 sets of direct changes to the Australian economy. These<br />
changes are often referred to as ‘shocks’ because they change the balance<br />
