Section 2
The mean was 56% - higher than 2012!
Strong correlation with exam total (0.93)
• Q25 – Productivity growth
Mean of 55.5% (Correlation 0.84)
• Q26 – Trading partners - descriptive
Mean of 61% (Correlation 0.81)
• Q37 – B of P & the exchange rate
Mean of 52% (Correlation 0.88)
Section 2
Question 25
Section 2
(b) Explain why the change in labour productivity
between Period 2 and Period 3 is a cause of concern
for the Australian economy. (4 marks)
Many students confuse productivity with production.
Also most students incorrectly stated that labour
productivity fell rather than the rate of productivity
growth slowed.
Need to spend more time on teaching the meaning of
productivity & the difference between labour
productivity & multifactor productivity.
What’s the difference?
Section 2
Labour productivity consists of 2 elements:
i) capital deepening – increasing the capitallabour ratio
ii) multifactor productivity – ‘real’ measure of
productivity, it is a measure of technical
progress & innovation
Section 2
(c) Explain how fiscal policy and microeconomic
reform can be used to increase labour productivity. (6
marks) - mean 46%!
Many students could not discuss how fiscal policy
could be used to increase labour productivity. Most
responses referred to expansionary fiscal policy as a
means for raising productivity rather than specific
measures such as spending on education and
training, R & D or investment on infrastructure
Section 2
Question 26 Australia’s
Trading Partners
(b) Describe the factors that have contributed to
Australia being a major exporter to China.
(c) Describe the advantages to Australia of the
increased linkages among the countries in the
Asia-Pacific region in recent decades
Many students simply talked about trade linkages
and failed to mention investment or immigration
Section 2
Question 27
Balance of
payments &
the $A
Section 2
27. (a) (i) What was the value of Australia’s current
account balance in 2006–07? Mean 29%!!!
(b) Describe and explain the relationship between the
change in net capital inflow and the change in the
exchange rate from 2000–01 to 2006–07. (4 marks)
Great data interpret question
It is evident that many students incorrectly think that
a high dollar causes an inflow of foreign investment
rather than foreign investment causing a rise in the
currency. This is an important teaching point that
should be addressed.
Section 2
27. (c) Explain how changes in domestic interest rates
affect the goods and services balance. (6 marks)
This proved difficult – mean 48%
1. An increase in i/rs will decrease C & I spending
which will decrease imports – the trade balance
will increase
2. But an increase in i/rs will appreciate the $A
which will increase imports & decrease exports the trade balance will decrease
Are you confused?

Section 3
Question 30
(a) Describe the economic conditions in Australia that
led to these policy stances. (8 marks) Mean 51%
Few students could explain why the budget deficit was
falling. Most simply focussed on the expansionary
impact of a budget deficit. The key understanding was
that the Australian economy was weak with economic
growth well below trend (2.5%) and unemployment
rising (5.7%). Contributing factors were the slowdown
in the Chinese economy, decline in domestic investment
and the high $A.
Section 3
Question 30
(b) Using a diagram/s, show how these policies can
help the Government achieve its internal economic
objectives. (12 marks) Mean 56%

policy can be use to offset a weak domestic economy

This was the most popular question!
But most students do not understand the causes of
business cycles - students simply described the phases
of the business cycle.

Good answers should have incorporated the AD/AS
model to show how changes in AD and/or AS can cause
fluctuations in economic activity
