    Do Underlying Measures of Inflation Outperform Headline Rates? Evidence from Australian Data
    Song, Lei Lei ( 2003-12)
    Many central banks often focus on underlying measures of inflation when assessing inflation trends. This paper compares the accuracy of underlying measures of inflation relative to the headline rates by using Australian data. It is found that the underlying measures did have smaller errors in predicting the long-term trend in inflation than the quarterly headline rate in the sample period 1977 to 2001 and the inflation targeting subperiod starting from 1993, due to the large volatility of the headline rate. As compared to the year-ended headline rate, the statistical test results , however, support only the measure of market prices excluding volatile items, not the others. There is some weak evidence of the weighted median measure outperforming the headline rate in the subperiod after 1993. With respect to directional accuracy, the test statistics cannot reject the null hypothesis of an equal probability correctly predicting the moving direction of the inflation trend, though the headline rates have a higher probability.

    Effects of the Australian new tax system on government expenditure with and without behavioural changes
    Kalb, G. R. ; Kew, H. ; Scutella, R. ( 2003-04)
    This paper uses the Melbourne Institute Tax and Transfer Simulator to examine the effects of the New Tax System introduced in Australia in July 2000. First the whole set of changes is studied and then some of its components are discussed separately. From the results it is clear that the change in income tax rates and thresholds had the largest effect, because it affected a large proportion of the population whereas the changes to the benefit system are only relevant to smaller groups. Families with children benefited on average most from the changes, firstly through the changes in income taxes and secondly through the changes in Family Payments. However, families with children were also more likely to experience a loss indicating a wider range of positive and negative outcomes for this group.
