Economics Exam Discussion + Suggested Answers!
« on: November 06, 2017, 05:24:35 pm »
Hi guys!!!

Congratulations for finishing your economics exam!!!! I'm going through the answers now, and will post them up as soon as I am done :)

But in the meantime, how did the exam go? Did it go well? What was your favourite section? What essay question did you choose?

Keen to hear your thoughts, and again, congratulations! For many of you that would have been your last HSC exam ever, so go you!!! Now off to a well deserved break :) If you have anymore exams to go however, then good luck! I'm sure you will smash it :)

Isaac (and sudodds, who is helping him type this up ;) )

DISCLAIMER!!!! I did the HSC last year and haven't studied this content for a year so I'm a little bit rusty and not in the HSC mindset - so these are a tentative answer for each question - definitely feel free to call me up on ones you think I got wrong - bound to be a few I promise since I'm not sure of at least 6!!!
Spoiler
1. D Migration laws that are encourage international labour mobility - TNC's encourage globalisation and more relaxed migration laws that encourage international labour mobility is a benefit since this encourages allocative efficiency and thus maximises production. The other answers are all drawbacks.
2. D Non-excludable and Non-rival - This is just the definition of  a public good that you can't stop someone from using it and one person's use doesn't diminish another persons use - think street lights
3. A Fiscal policy has a longer implementation lag than monetary policy - This is true because fiscal policy needs to pass both houses of parliament before it can be implemented having a medium lag whereas monetary policy can be immediately implemented by the RBA (monetary policy has a medium impact lag and fiscal has a short impact lag; micro policy has a long implement and impact lag :D)
4. A Expansionary fiscal and monetary policy - Since there is high unemployment; this must be addressed through expansionary policy to increase the demand for goods and services and thus decrease unemployment. Also since inflation is quite low, this should be stimulated through expansionary policy as well (monetary is usually the one that responds to inflation more so expansionary monetary policy is required) therefore expansioinary stances for both policies will address these problems
5. B Aggregate Supply in Australia - To improve international competitiveness, the price of our exports should be less than foreign competition; by increasing inflation, spending or the dollar value; we would increase the price of our exports and make them less internationally competitive thus an increase in aggregate supply will decrease the price of exports and improve international competitiveness. This is because a shift out of the AS curve will translate to an expansion in AD down the curve to a lower price level but higher growth.
6. A Fines for firms that pollute - Since market based policies are things that provide incentives to change production (usually through internalising the cost of subsidising production) the most correct answer is a fine since the others are about targets that dont intervene in the market B Firms buying and selling pollution permits I was tossing up between these two answers - the only reason I chose A was that a fine would definitely increase the cost and discourage pollution - I wasn't too sure about how buying and selling permits would do the same since the permits already exist in the market and firms would just buy and sell them between each other depending on how much pollution was produced - I didnt know if it internalised the cost (sorry I'm a bit rusty on this topic)
7. B an increase in the tax free threshold - government policies are counter cyclical meaning that they aim to reduce fluctuations in the business cycle. Excessive fluctuations would necessitate government intervention to smooth out the business cycle - this is usually achieved through increasing the impact of automatic stabilisers i.e. by increasing the tax free threshold it affects the progressive tax system which in itself is non discretionary. C decrease in company taxation receipts was my first answer and I have circled it - the only reason I chose B was that the fluctuations of the business cycle (it didnt specify international so I assumed it was domsetic) would not necessarily cause a decrease in tax receipts since it could go up and down depending on where the economy was in the business cycle - im not too confident with this one so what do you guys think and why??
8. A upward pressure on interest rates Government's funding a deficit by borrowing domestically triggers the crowding out effect in that the government borrows from the private sector and uses national savings that could be used for investment. However when national savings decrease, it increases the interest rate since the lower supply means businesses will compete for investment (not literally) and thus put upward pressure on interest rates
9. B the domestic price of the product will increase - by reducing the import quota they are effectively decreasing the amount of imports they let in and increasing protection. Because of this, the domestic price of the good rises since there is excess demand that can't be satisfied unless more domestic suppliers produce the product. Thus the price increases and domestic production increases whilst importer production decreases
10. A they are legally employed The most basic requirement to earn the minimum wage is that they are legally employed (working for more than one hour a week) the other options are all types of employment contracts that usually are above the minimum wage to cater to the specific industry.
11. C the price of Australia's imports increased relative to the price of Australia's exports - Since the TOT decreased from 115 to 105; it means that either export price index fell or the import price index rose (basically meaning that we spend relatively more on imports than we receive for exports). TOT only measures the price of the traded goods not the value of them - different concept that requires looking at inflation and volumes. Therefore it is the price of imports relative to exports.
12. C Returns to labour, returns to enterprise, returns to land and capital transfer payments - Using the 2015 data on the Australian National Accounts (this may have changed from last year) but Wages accounted for 54.8%, Profit was 18.5% (returns on enterprise), Rent, interest and dividends was 11.5% and Social Benefits was 10%
13. A a depreciation of the Australian dollar - If there was a downturn in a major trading partner who bought our exports then this would equate to a decrease in the demand of the Australian dollar and contribute to a depreciation. There is not enough information to say what would happen to the demand and supply of the foreign currency.
14. D it is contracting because leakages are greater than injections - Since injections is (20+25+70)=115; and leakages are (35+30+60)=125; leakages are greater than injections which means more money is leaving the economy than being injected and thus contracting.
15. B 2 - the unemployment rate = unemployed/labour force and the participation rate is labour force/working age population - when you put the values given in the formula you should get year 2 in which working age population = 8, employed = 3, unemployed = 2 and labour force = 5.
16. C they increase at a decreasing rate. - The trick with this question is that even though CPI increases by the same value - inflation is calculated through the change in CPI. So even though it changes from 100 to 105 to 110 - the inflation rate is 5% in year 2 but 4.5% in year 3 therefore the price of goods are increasing but at a decreasing rate.
17. C the net errors and omissions are larger in Year 2 than in Year 1 - so to calculate on the BOP we would see that the in year 1 the CAD = -100 and KFA = 95 and Net errors and omissions = 5; in year 2: CAD=-130, KFA=120 and Net errors=10. Therefore net errors and omissions has increased and is larger in year 2 than in year 1.
18. B only one person can read the book at a time. - this question asks you to look at the definition of a public good being non-excludable and non-rival - therefore you had to find the option where one persons use diminished another persons use or you could stop someone from using it. The fact that only one person can read the book at a time means that another person's use is diminished. The other options don't show exclusivity or rivalry.
19. D X=2000, Z=700 - This question confused me at first but you have to recall that the multiplier is 1/(1-MPC) which the question says is 2.5. Then we can see that   1=2.5-2.5MPC --> 2.5MPC=1.5 ---> MPC = 0.6. Then since MPC = the change in consumption/the change in income.therefore we can see that as income rises by 1000, consumption increases by 600 therefore Z=700 since C was originally 100.
20. B Australian exports to the US are less expensive in 2020 compared to 2019 - This one requires a lot of understanding the question and recognising the different exchange rates - it really helps to dominate the exchange rate into just one currency so you would have the USD/AUD exchange rate being 0.8 in year 1 and then 0.75 in year 2. Meaning that the Australian dollar depreciated therefore exports to the US are less expensive.

Short Answer
21 (a) Why can dumping be used as a justification for trade protection?
So for this question you would want to define what dumping is and how it decreases domestic producer's market share and thus can lead to unemployment within the economy. an adequate explanation of that would have got you 2 marks!

21 (b) Explain the difference between subsidies and local content rules in discouraging dumping
So for this one I would split it between subsidies and local content rules.
For subsidies you firstly define what it is then you would want to say how it decreases production costs for domestic businesses and allow them to decrease their price to consumers which would help them compete with foreign dumping. Drawing a diagram may have also elevated your answer here!
Then looking at local content rules; this places a minimum level of domestically produced products and thus can diminish the level of foreign dumped imports that can be sold in the market.
Any logical explanation that linked how subsidies and local content rules discouraged dumping would have gotten you 4 marks. (2 for each method)

21(c) Compare and contrast the roles of the IMF and the World Bank in international economic integration
So definitely look at what the IMF does in terms of international financial stability but also the question focuses on international economic integration. So you would want to say how it promotes globalisation one of the big things the IMF does to promote free trade is to encourage the deregulation of financial markets and reduce capital controls through giving out advice or lending with strict austerity measures to deregulate their markets. Another thing you could say is that it attempts stops financial financial crises from spreading globally through providing loans to countries facing crises.
In looking at the world bank, it mainly gives out loans to developing countries to fund infrastructure and promote economic development. This organisation is less orientated towards globalisation and more towards equality and economic development. To some extent, economic integration is encouraged through coordinating multilateral aid towards developing countries. Also the world bank does try to encourage globalisation through influencing developing countries to adopt policies that create conditions favourable for foreign investment and efficient markets to allow for economic growth and development. These include reduction of subsidies, trade liberalisation and removal of capital controls. Sometimes, aid is conditional on these structural adjustment recommendations.

So you needed to firstly identify what each organisation is and how it promotes globalisation; then you want to compare and contrast the two in how significant their approach to globalisation is.

22(a) A large agricultural property in Australia is sold to a foreign investor. Outline how this transaction can affect TWO component of Australia's balance of payments.
This question relies on a few assumptions that I made. Firstly that the property was used as a business and that the investor was investing in the business. Secondly I assumed that since it is a "large" property meaning that it was a large investment with a controlling interest.
Using these assumptions I would say that the investment was a credit in the financial account since it is money coming into Australia and on the financial account due to it being direct investment.
However when the business makes profits in the long term; these profits will be paid back to the foreign investor as dividends which are recorded as a debit on the primary income account.

22(b)Distinguish between direct investment and portfolio investment.
This one is pretty simple in that direct investment is when you gain a controlling interest in the company more than 10% whereas portfolio is anything less - usually speculative

22(c) Discuss the costs and benefits for Australia of foreign direct investment
for this one you could have talked about:
Costs
  • future profits being leaked out of the economy
  • taxation incentives means that government receives very little taxation revenue
Benefits
  • increased investment can increase infrastructure and inject funds into establishment of companies
  • increased employment and thus increased incomes which allow people to buy more goods and services (increased standards of living)
  • increased technology flows and spillover which can increase efficiency nationally
Those are just a few you could have mentioned - let me know what you guys put down!!

23(a) Distinguish between income and wealth
Income is the amount of money a person earns each a year for owning, maintaining and managing productive resources of land, labour, capital and enterprise whereas Wealth is the monetary value of assets that are currently owned including savings of previous income.

23(b) Explain two ways in which taxation can be used to change the GINI coefficient from 0.5 to 0.2.
A decreased gini means that the economy is moving to a more equitable distribution. This can be achieved through increasing the marginal tax rates of higher income earners (more money will be taken from those who earn a lot) and then increasing the tax free threshold (those with lower incomes will keep their original income) and this will bridge the gap between the two.
Other answers could be things like decrease the GST since it is a regressive tax. If you explain how this tax would bridge the gap between high and low income earners effectively then this should get you 4 marks.

23(c) Explain how age and gender affect wealth inequality
so firstly for age - you would wanna say how they are quite young and thus dont have as much time to accumulate financial assets like shares/houses. You could also talk about the fact that employment available to them is usually low skilled (little work experience/qualifications) which is low paying thus their accumulated savings is likely to be low. You can also mention how they are young and have little knowledge of stock markets or ways to increase wealth.
In looking at gender, you would wanna talk about the gender pay gap and how there is an unconscious bias and discrimination that occurs in the workplace preventing women from entering higher paying managerial roles. This inability to accumulate income and savings will create wealth inequality. Thus, these two demographics are more likely to suffer higher levels of wealth inequality contributing to greater overall inequality in the economy,

24(a)Identify one type of unemployment that is present at full employment and one type that is not.
Present at full employment: You could put a few such as structural, frictional, seasonal, hardcore, long term
Not present at full employment: The main one here is cyclical unemployment.

24(b)Explain how unemployment affects economic growth in an economy.
Unemployment means that some resources are underutilised in the economy. When this occurs it means that some resources can't be used in production and thus limits the amount of goods and services that can be produced over a period of time. You can also look at structural and long term unemployed people start to lose their skills over a period of time when they aren't demanded meaning that if they enter the workforce the quality of labour decreases. This results in inefficiency and constrained economic growth.

You could also argue that unemployment creates inequality meaning that some people are incentivised to learn new skills and work harder which can contribute to improved economic growth in the long term.

24(c) Contrast the use of fiscal policy for an economy at the non-accelerating inflation rate of unemployment (NAIRU) with its use when the economy is above the NAIRU.
So fiscal policy for an economy at the NAIRU would mean that any expansionary stance to decrease unemployment would result in higher inflation.
When the economy is above the NAIRU it means that at the current level of unemployment there is a higher rate of inflation due to the fact that there is no cyclical unemployment in the economy and that structurally and frictionally unemployed people get sucked into employment due to a higher rate of demand. When this occurs firms attempt to attract the skilled labour by increasing wages. An economy at this point would want ot dampen economic activity through contractionary fiscal policy. Moreover they would want to use fiscal policy to undergo structural reform in order to reduce the level of structural and frictional unemployment and thus decrease the NAIRU - can be done by higher expenditure into retraining programs, job finding agencies etc.)

My interpretation of the question may be a bit wrong, sorry everyone, if the economy is above the NAIRU it can mean there is a little bit of cyclical unemployment - i interpreted the question on the graph as in we were above the NAIRU point. But in that were the case, the government would try to decrease cyclical unemployment by increasing growth using expansionary fiscal policy. Whilst simultaneously trying to reduce the NAIRU since they could be fast approaching it. However I would also write in that it would depend on the government's objectives and targets for unemployment/inflation!

Extended Response
Q25 Analyse the implications of a decline in global economic activity for Australia's policies. In your response, refer to the economic information provided
For this question it is really important to look at the stimulus given and see that it gives you terms of trade and the cash rate and exchange rates. This should indicate the concepts that NESA wants you to be talking about.
So definitely have a trend analysis to start (after an introduction) some stats and talk about the international business cycle (could have drawn the diagram) and how global economic activity has fallen - you could maybe give a few reasons why it has declined - low consumer confidence after GFC, end of the commodity/mining boom, end of China's emergence...
Then you could look at how this affects the demand for exports and thus commodity prices (bring in the TOT stats they give you) and say how the government will respond to this - diversify economic base etc.
Another thing could be looking at how it affects domestic growth (low confidence/low exports) and how expansionary monetary and fiscal policy is required.

Q26 Analyse the role that the Australian government's economic policies play in achieving price stability in Australia. In your response, refer to the economic information provided.
For this question you would have to look at price stability i.e. inflation and evaluate the policies to control inflation.
Monetary policy - main way to affect inflation - talk about the cash rate (use info given) as well as how it is more ffective at curbing inflation than increasing inflation.
Fiscal policy - talk about how it affects inflation through aggregate demand
Micro - look at how reforms affect productivity and shift AS curve to create sustainable growth at a lower level of inflation
Since they gave you info on the exchange rate you should talk about how this impacts inflation and how the government is responding to it --> dirtying the float as well as how the sustained depreciation has bee affecting inflation (imported inflation).

Q27 With reference to BOTH Australia and one other economy, compare and contrast the effects of globalisation on economic growth and environmental sustainability
So this one you would most probably use your case study - since I only did China I can only talk about that one.
But for this question look at how globalisation has impacted each economy so:
Investment --> Economic Growth - normally through increased investment - increased employment then increased activity and production
Economic development
Inequality - this might just be specific to China
Environmental sustainability - in looking at China - their increased production caused a massive increase in pollution which has significantly degraded their air quality and environmental sustainability - led to further respiratory illnesses.

Then you would look at how each country was affected differently and why - so China implemented special economic zones to incentivise TNC investment which allowed their coastal regions to industrialise and expand rapidly but created vast inequality whereas Australia did a lot of deregulation and liberalisation in financial and trade markets to allow an increase in investment. Contrast the level of TNC's - attributed to Australia's higher labour costs etc.

Q28 Explain how labour market policies can be used to achieve Australia's economic objectives
This one requires you to look at the governments economic objectives and say how labour market policies can be used to achieve them --> this is a really long essay since you would have to look at most of the objectives.
Decentralisation - wage bargaining - incentive to work harder --> increase growth thorugh increased AS but inequality
Minimum wage - affects inequality but also inflation and unemployment since some people wont be employed (look at the supply and demand for labour)
Education/training and employment programs - help decrease structural and frictional unemployment and thus affect growth through getting closer to the Production possibility curve

Id love to know what you guys wrote down for these ones - albeit I found these quite a struggle so interesting to hear what people who have studied the course recently would think!!


Congratulations everyone!!! You did it!!! You've all smashed eco and smashed the HSC can't wait to hear how you all went

Chose Q26 and Q28 (mainly because I forgot stats for Aus for Case study) but doing labour market ended up helping for Q26. Multiple choice was decent. i think I messed up 1 short answer but very good exam overall

I really hope I'm not the only person who found that hard...
My MC was good, I usually find this the hardest so I'm glad I improved but it says a lot about the rest of the exam.
SA I found myself waffling a lot because I was overcomplicating things from trying too hard, I knew everything in my head but found it hard to put into words on paper... Hopefully the markers can see where I'm coming from.
And the essays? What the hell? I ended up choosing Q25 and 27, but definitely regret not choosing 26, and only just didn't finish 27, as well as all of my case study being BS (Believable BS tho ;) I think this was definitely my weakest section, was really hoping BOP and protectionism would be asked, guess not lol.

Either way, I think the paper was difficult and will hopefully scale better than average.

Glad my final exam is done now, the goal is Economics at USYD, time will tell :)

Yeah the essays were so unexpected... Like as if they had no fiscal policy..?? Its one of the main economic topics of talk this year...

I think i screwed it up really bad, chose the labour market policy question and wrote a full paragraph on how wage determination can help the government achieve it's goal of price stability, how many marks do you guys think ill lose?

I thought for Q4 it would be contractionary monetary policy as that is equivalent to tightening. Tightened monetary policy leads to increased interest rates which increases inflation. If so the answer I put was C

they did... for q25 or q26 you could talk about fiscal (the stimulus for q 25 talked about fiscal and monetary)
