Net national saving as a proportion of GDP
Income that is saved rather than being spent on current consumption can be used to accumulate assets (wealth) that will generate future income and support future consumption. In particular, saving is one means of funding investment (the formation of fixed capital used in the production of goods and services).
During the past decade, there was a 0.8 percentage point rise in the ratio of net national saving to GDP (from 2% to 2.8%). But the longer term trend has been downward; between 1960-61 and 2000-01 the ratio fell overall from around 10% to around 3%. Similar downward trends in national saving have been observed in some other countries, such as the United States of America and the United Kingdom.
There is an important distinction between gross and net national saving (see box). The ratio of depreciation to gross saving has risen during the past forty years - from an average of around 64% in the 1960s to around 88% during the 1990s. This means that proportionately less of Australia's saving has been devoted to increasing the national stock of fixed capital and more to replacing the existing stock.
Net national saving as a proportion of GDP, by sector
SOME DIFFERENCES WITHIN AUSTRALIA
Net national saving can be dissected to show the trends in saving by the various sectors - households, general government and corporations.
Over the longer term (from the 1960s onward), the household sector has been the main contributor to national saving. During the 1990s, however, the net saving of the household sector has fallen relative to GDP.
The general government sector went from being a net saver during the 1960s to a net dissaver during the 1970s, 1980s and early 1990s. During the 1990s, however, government dissaving was progressively reduced; between 1997-98 and 2000-01 the government sector again became a net saver.
For the corporate sector (financial and non-financial corporations) there have been considerable fluctuations in saving since the 1960s. For much of the 1990s, however, the corporate sector has been a net saver - possibly reflecting an increasing tendency for corporate profits to be retained rather than distributed to households in the form of dividends.
FACTORS INFLUENCING CHANGE
National and sectoral saving may be affected by both cyclical and behavioural influences.
For example, the economic cycle has a significant influence on government saving (as outlays tend to rise and receipts tend to fall during an economic downturn). In Australia, the government sector experienced a period of dissaving following the recession in 1991. The rise in government saving in the late 1990s in part reflected sustained economic growth and fiscal consolidation. The possible changes to the corporate sector's distribution of profits in the form of dividends during the 1990s are referred to above.
Changes in rates of inflation can also affect saving rates. A certain amount of saving is required to 'protect' the real value of assets which would otherwise fall due to inflation. In periods of lower inflation - such as the 1990s - less saving might need to be set aside for this purpose.
