Figure 4.5 shows the contributions made by different components to the decline of the overall PSTN sub-index in 2013−14.

Figure 4.6 shows the proportion of consumer expenditure attributed to each component of the PSTN sub-index in 1997−98 and 2013−14. Basic access and fixed-to-mobile calls accounted for a much greater proportion of total consumer expenditure in 2013−14 than they did in 1997−98, whereas the proportion of consumer expenditure on PSTN international call services has reduced significantly.

In 2013−14, the real price of PSTN services fell by 5.1 per cent (table 4.4), which was a greater decline than in 2012. The residential PSTN services index was the dominant driver of the price decline for the overall PSTN services, contributing to the PSTN price decline by 3.3 percentage points whereas the business PSTN services index contributed to the overall PSTN price decline by only 1.9 percentage points.130 Table 4.4 below shows the year-on-year percentage changes in the PSTN services index since 2004−05.

4.2.2 Price movements in the PSTN residential index
The PSTN residential services index is derived from average real prices paid by residential consumers for each component of PSTN services. Average prices of residential PSTN services declined in 2013−14 by 5.5 per cent in real terms.
Table 4.5 shows the movement in the service components of the PSTN residential index over the past decade. With the exception of national long-distance calls, real prices decreased across every service component of the PSTN residential index in 2013−14.

Figure 4.7 shows the extent to which each service component contributed to the change in the PSTN residential index in 2013−14. Basic access services were the largest contributor towards the fall in the index followed by fixed-to-mobile services. The slight increase in the real price levels of the national long-distance calls were offset by the decline in real prices for all other services making up the residential PSTN sub-index.
