4.11 It can be seen that over the period 1989–90 to June quarter 1998, the modest 11.8% increase for domestic Final goods can be attributed to the dampening effect of export prices. A marginal rise of 1.2% in Export prices over the period offset the much more substantial 18.6% increase in prices of goods destined for domestic final consumption and capital formation. When combined with imports the total Final goods index, excluding exports, rose by 20.0%.

4.12 A further observation is that for both domestic and imported Final goods, prices of consumption goods increased slightly more than prices of capital goods.

4.13 Returning to the table in paragraph 4.7, the index for domestic Intermediate (Stage 2) goods rose between 1989–90 and June quarter 1998 by less than the imported series (13.0% compared with 17.4%) leading to a 13.8% increase in the total Intermediate goods index.

4.14 For Preliminary (Stage 1) goods, the domestically produced series increased between 1989–90 and June quarter 1998 by a greater amount than the imports series (10.6% compared with 8.6%) resulting in an increase of 10.2% in the Preliminary goods index.

4.15 It is interesting to note the different impacts of import prices on the total indexes for each stage. In the case of Final goods, import prices had a substantial upward impact while for Intermediate goods, prices of imported goods had a more modest upward impact. However, for Preliminary goods import prices had a moderating influence.

4.16 Another observation is that, for each Stage, the series for imports is far more volatile than the series for domestic goods (see tables 4 and 6). This is largely attributable to exchange rate movements.

4.17 In summary, the growth in the index over the eight-year period for each stage progressively increases as shown below:

Preliminary goods

+10.2%
Intermediate goods
+13.8%
Final goods (excluding exports)
+20.0%.

4.18 The table in paragraph 4.10 shows that the 20.0% increase in Final goods (excluding exports) prices comprises price increases of 20.2% for Consumption goods and 19.6% for Capital goods. The 20.2% increase in the producer price index for Final Consumption goods can be compared with an increase of 23.1% over the same period for the goods component of the Consumer Price Index (table 7 of Consumer Price Index, June Quarter 1998 (Cat. no. 6401.0)). This indicates a continuation of the progressive increase in the growth of prices of goods as they advance along the production and distribution chain associated with, for example, wholesale, transport and retail margins being added to the value of the goods.

4.19 This progressive increase in the growth of goods prices over the eight-year period of study could be attributable to price pressures from other inputs, apart from goods. That is, prices of intermediate inputs of services as well as goods, labour costs, indirect tax rates and changes in profit margins also need to be considered. Prima facie, it could be deduced that, taken together, the prices of these other inputs rose at a greater rate than the prices of goods over the period, culminating in the progressive increases along the production and distribution chain.

4.20 Obviously a more complete statistical framework is required to support a rigorous study of inflation processes. A comprehensive SOP data model, intended for this purpose, is articulated in Chapter 5. Further analysis of the available data is also undertaken.
