6.26 The ABS publishes two types of price index in the national accounts:
- chain Laspeyres price indexes; and
- implicit price deflators (IPDs).
6.27 The quarterly chain Laspeyres price indexes are derived in the same way as the quarterly chain Laspeyres volume indexes, but they are only derived in original terms and are not seasonally adjusted.
6.28 The IPDs are derived by dividing current price values by the corresponding chain volume measures (CVMs). These are only derived using seasonally adjusted data. They are thus seasonally adjusted chain Paasche price indexes.
