3.2 Part 2: Measuring economic growth
and living standards
Calculating grows
domestic product (GDP)
Eco growth occurs when there is a rise in the real
value of finished goods and services produced in Aus
b/w one year and the next.
GDP is the most common measure. Prepared
every quarter and four quarters show the annual
rate of eco growth
Looking back at the circular flow novel, It's
possible to see that the value of goods and
services produced or GDP (flow no.4) can be
estimated in three ways.
The model assumes that the three flows of total
expenditure on production (no.3 or AD) , total incomes
paid to those selling resources (no.2) and total production
(no.4 or GDP) are all exactly equal in value.
Estimates on GDP can be made in three different ways.
1. GDP (E)
should be equal to the total annual market value of expenditure
on final goods and services produced in Australia
Basically AD
GDP consists of the annual sum of private consumption (C)
+ investment spending (I) + government consumption (G1) +
government investment spending (G2) + overseas spending
on exports (X) - our import spending (M)
2. GDP (I)
GDP should also be equal to the
total value of incomes paid to those
selling resources needed for
production
Incomes here include wages + salaries + supplements + profits of firms
3. GDP (P)
GDP should also be equal to
the total market value of final
goods and services produced
each year.
equal to the value of
production each year
Value added in production refers to the total market
value of sales - the cost of all inputs purchased by
firms.
Impossible to include all forms of
production in GDP - this would be
too complicated
Some things are excluded from GDP such as the
value of the black market, home duties like
parenting and backyard DYI jobs.
Calculating chain volume GDP
and allowing for changes in
price levels.
Inflation and deflation affect the growth
rate in market value of final goods and
services produced each year.
misleading impression of the actual size and
change in the volume of g/s produced each
year
Inflation would exaggerate the rise in market value g/s
produced and sold while deflation would underestimate
these values.
nothing was done to take these measures into consideration, GDP would be pointless
ABS now removes the impact that annual price changes
would have on the value of production measured at
current or market prices by using a measure called chain
volume GDP.
Chain Volume GDP - market value of goods and services
produced by Australia, adjusted to remove the effect on
the value of national production caused by changes in
prices against a reference year.
uses a
chain price
index to
help
deflate the
figures or
inflate
them
chain price index measures the average change in the prices of
goods and services relevant to expenditure on GDP for the most
recent year, against the prices that existed in a selected base
year or reference year
