• An electronic copy 1 must be submitted in CloudDeakin by 11.59pm on the due
date. Penalties 2 apply to late submissions unless prior arrangements have been
made by the Unit Chair.
• You must attach an assignment attachment sheet 3 , which includes a plagiarism
declaration: see the unit guide for details. Please note that digital signature of
the plagiarism declaration IS acceptable.
• Digital literacy is one of the Deakin’s Graduate Learning outcomes and among
the Unit Learning Outcomes of MAE101. It requires the students to be capa-
ble of using modern technologies to find, use and disseminate information. To
achieve this goal, it is required that ALL contents of your assignment should be
digitally produced, including explanations, diagrams, and mathematical deriva-

tions, etc 4 .
To receive full marks you must show clear development and expression of economic
ideas in clear paragraphs in addition to the correct answers. You may use dot-points or out-
lines to develop your thinking, but then re-write them into proper sentences and paragraphs.
Please use 12pt sized font and double-space format. You must cite all ideas that are not
your own. You should use the Harvard (name-date) referencing style, to cite any source
you use – perhaps to confirm your results with the text. It means that, rather than placing a
reference in a footnote, you should provide reference of the work inside the text with the
name of the author and the date of publication of the work cited. Example:
Far from being the inventor of the idea of perfect competition, Adam Smith
was in fact among the last representative of economists who saw competition
as a dynamic process of rivalry (McNulty 1967).
This means you are citing a 1967 article authored by someone called McNulty as the source
of the idea in the sentence. You would then list that article in a list of references at the end
of your paper:
• McNulty, Paul J. 1967. “A Note on the History of Perfect Competition,” Journal of
Political Economy 75(4): 395-399 (August)
There are many ways to run the details of a name-date style. You should pick up only
one style and use it consistently. Please see the Harvard webpage put out by Student Life
not just quote chunks of the text – you must express your answer in your own words.
4 Instructions and video clips on how to use computers to generate graphs and mathematical expressions can
be found on CloudDeakin unit website in the assessment folder.
You may study with other students, discuss the assignments with whomever you wish
and even outline answers with others. However, you must write this assignment on your
own. Software will check each assignment for plagiarism and collusion, which are ex-
plained in our Unit Guide. Severe disciplinary measures could be taken as explained in the
Unit Guide. We realize that some sentences will occur in different students’ work because
there are few ways to say them, e.g., “Price decreased from P 1 to P 2 .” However there should
be few such matches between any two assignments, and even the process of resolving the
case of accidentally matching someone else’s work can be time-consuming and upsetting.
So, please do your own work. It is preparation for the exam.

that hand-drawn diagrams are usually unacceptable in professional business documents.
1. Opportunity cost is a key concept in Economics. The textbook defines the opportu-
nity cost as the best alternative that must be given up to obtain some item. Use the
opportunity cost concept to develop response to the following questions:
(a) Suppose you are a music fan. Lucky enough, you won a free ticket to see a local
rock-band concert tonight (with no resale value). There are two other concerts
on the same night: one for Taylor Swift and the other for Katy Perry. These two
concerts are the only other activities you are considering. The ticket prices for
Taylor Swift and Katy Perry’s concerts are $90 and $85, respectively. And on
any given day you would be willing to pay up to $110 to see Taylor Swift or
$100 to see Katy Perry perform. In other words, if Taylor Swift tickets sold for
more than $110, you would pass on the opportunity to see her even if you have
nothing else to do. Similarly, you will pass on the opportunity to see Katy Perry
if her concert costs you more than $100. There is no other cost of seeing any
of these three concerts. According to the information provided, what is your
opportunity cost of attending the local rock-band concert? Briefly explain your
(b) Sally owns a local souvenir store. One of the most popular items in her shop
is the opal bracelet she made. An opal bracelet costs Sally $28 on average, and
is sold for $45. She unfortunately accepted a traveller’s cheque of $100 from a
tourist who purchased two bracelets and gave him $10 change. Sally then gave
the cheque to her landlord but it bounced so she had to get $100 cash from her
bank account to pay her rent. The ongoing interest rate is 3.5%.
i. How much money has Sally lost in this incident? Briefly explain your an-
ii. Would your answer to the last question change if the opportunity cost is
considered? If so, what is the opportunity cost of this incident? Briefly
explain your answer.
iii. Sally learns from this incident and decides to never accept any traveller’s
cheques in the future. Is it a wise decision? Briefly explain your answer.
2. During 2010–2011, a series of floods hit Australia, primarily in the eastern coast
areas including Queensland and Victoria. At least 70 towns and over 200,000 people
were directly affected. The estimated damage in Australia’s GDP is about $30 billion
(ABC News Online, 18 January 2011). The floods also took a toll on the potato

industry. As a consequence, the potato market has received a lot of attention.
(a) According to a study on the Australian potato market, at the price of $2.99 per
kilogram, a regular household consumes about 7.6 kilograms of potatoes per
month. The consumption of potatoes drops to 6.5 kilograms per month when
the price is at $4.99 per kilogram.
i. Based on this information, use the mid-point method to compute the price
elasticity of demand for potatoes in a regular Australian household.
ii. There are many ways to categorize the goods in the market. For example,
there are normal goods and inferior goods, regular goods and Giffen goods,
necessities and luxuries, etc. According to your answer in the last question,
what type(s) of good does the potato belong to?
iii. Some scholars argue that the estimate of the elasticity calculated in (i)
might be unreliable. Briefly explain why.
(b) Since potato is an important food for Australians, soaring potato prices could
substantially affect the living standards of many households in Australia. In or-
der to avoid the disastrous consequences, the Australian government can adopt
some price control schemes. Suppose you have been provided with the follow-
ing information regarding the demand and supply of potatoes:
Q d = 9−0.5P
Q s = −0.5+1.4P
where Q d , Q s and P are the quantity demanded (in kilograms), the quantity
supplied (in kilograms) and the market price (in dollars), respectively.
i. Calculate the equilibrium price and quantity of potatoes.
ii. Suppose the Australian government decides to impose a price ceiling of
$4.00 per kilogram on potatoes, what will be the new market price and
iii. What will happen to the market price and quantity if the price ceiling is set
at $6.00 per kilogram on potatoes?
(c) Starting from the equilibrium of the potato market given in the last question,
use standard demand and supply analysis to answer the following questions:
i. If the Australian government subsidizes consumers and gives one dollar
for every kilogram of potatoes purchased, what are the expected effects of
such a scheme on the equilibrium price and quantity of potatoes? (See Page
137-140 of Gans et al., 2012, for a detailed discussion of subsidies).
ii. If the Australian government subsidizes the potato-growers and gives one
dollar for every kilogram of potatoes produced, what are the expected ef-
fects of such a scheme on the equilibrium price and quantity of potatoes?
iii. Instead of subsidizing only consumers or growers, if the Australian govern-
ment decides to evenly split the subsidy to both parties, i.e., give 50 cents
for every kilogram of potatoes purchased by the consumers, and another 50
cents for every kilogram of potatoes produced by the growers, what are the
expected effects of such a scheme on the equilibrium price and quantity of
(d) Suppose an economist observes the following monthly data on the market price
and quantity of potatoes purchased in Geelong during the year 2015:
Month Jan. Feb. Mar. Apr. May Jun.
Price ($ per kilo) 2.99 2.52 2.90 3.15 3.69 3.44
Quantity (tons) 342 357 345 321 300 334
Month Jul. Aug. Sep. Oct. Nov. Dec.
Price($ per kilo) 3.44 4.93 4.84 4.21 1.87 1.51
Quantity (tons) 346 208 233 289 427 475
Based on the data, the economist plots the observations on a graph below with
quantity andprice on the horizontal and vertical axis respectively. He claims
this graph approximates the demand curve (the solid straight line) for potatoes
in Geelong for 2015. Do you agree with the economist’s claim? Explain your
answer in details.
3. A survey reported in 2009 reveals the following production conditions for Cyprus,
Slovenia and Slovakia. An average Cypriot worker could produce either 5 units of
wine or 12 units of rye in a year. An average Slovenian worker could make 7 unit of
wine or 5 units of rye annually. In Slovakia, a typical worker could make 3 units of
wine or 3 units of rye in a year.
(a) Draw the Production Possibilities Frontiers (PPFs) for Cyprus, Slovenia, and
Slovakia in terms of units of wine and rye in year 2009, placing the number of
wine units on the vertical axis and the number of rye units on the horizontal
axis. (Hint: You need information about these three countries to transform the
individual productivity into the national productivity.)
(b) After being accepted as members of the European Union (EU), Cyprus, Slove-
nia, and Slovakia have joined a single market through a standardised system of
laws that apply in all EU member states. Specifically, all three countries agreed
to allow the free movement of people, goods, services, and capital. In other
words, these three countries have become an economic community, with their
individual markets for factors of production been integrated into a united one.
Draw the community’s PPF, placing the number of wine units on the vertical
axis and the number of rye units on the horizontal axis. Show your workings.
(c) Australia adopts an immigration policy that favors applicants of certain occu-
pations, such as accountants, cooks, and hairdressers. This policy has been crit-
icised by many politicians and scholars for being discriminating and inefficient.
Justify this policy by using the tool of PPF and the example given in (a) and (b).
Can you develop some policy proposals to promote the fairness and efficiency
of this policy? Why do you think they will work better than the current policy?
