Assignment questions
Question 1: The economics of sales tax and online shopping
(Learning Outcomes: ULO1/GLO1, ULO2/GLO3 and ULO3/GLO4)
Imagine a company, A, that sells goods through its physical stores as well as an online trading
platform. Initially there is no sales tax on goods irrespective of whether they are sold through online
or physical stores. Then assume the government imposes a sales tax of $2 per unit of the good
(assuming a fixed amount of tax) only on goods which are sold at the physical store. The company
collects the following data on its sales, which is provided in the following Table 1:
Table: 1

Price per unit of goods
at Physical store
Quantity sold at
physical store
Quantity sold via online
at price $7 per unit (as
they are not subject to
sales tax)
Before sales Tax $7 3 6
After sales Tax $8 2 8

a. Calculate the own price elasticity of demand for the quantity sold at the physical store?
5 points
b. Based on your results to part (a), do you think consumers who purchased at the physical store
are responsive to the sales tax? Explain.
3 points
c. Calculate the total revenue of company A before and after the sales tax. Does the sales tax affect
company A’s total revenue? Explain.
7 points
d. Calculate the cross-price elasticity of the. quantity sold online with respect to the price per unit
of goods sold at the physical store. Use your answer to explain what cross price elasticity measure
5 points
e. Now suppose Table 1 provides us equilibrium price and quantity, then draw a demand and supply
diagrams for the market of company A’s physical store as well as its online store. Name and fully
label your diagram including both axes and indicate and explain points of interest using P for
price (P
1, P2 etc) and Q for quantity (Q1, Q2 etc). Hints: For simplicity assume that supply curve is
upwardly sloped, and the diagrams are consistent with Table 1.
10 points

f. Now work further on your diagram in part (e) to show the impact of a sales tax on quantity sold
at the physical store. Illustrate and explain how the sales tax affects the consumers of the
physical store. Also indicate the area on the diagram that represents tax revenue. How much
burden of tax is born by an individual consumer as well as an individual seller?
10 points
g. Classical economists argue that, everything else remains the same (i.e. in the absence of
externalities or market failure), any sort of government intervention on a competitive market
leads to inefficiency. If so then answer the following questions:
i) Do you think that the classical economists are right, in particular, for our case of where
a sales tax is imposed on the sales of a physical store? Calculate deadweight loss (if it
exists!) for physical store (after sales tax) in supporting your argument and also show the
deadweight loss with an appropriate diagram.
ii) Read the article (attached) titled “Consumer behaviour in online shopping is affected by
sales tax” carefully. Explain how online consumers respond to sales tax imposed by the
US government.
15 points
Question 2: Online shopping tax in Australia and Amazon
(Learning Outcomes: ULO3/GLO4 & 8)
An article published by Chung, F. (2018), “Turnbull’s online shopping tax punishes Aussie
consumers: How to avoid the Amazon rip-off”. The article is attached to this assignment question.
The article is interesting as it analyses the implications of an on-line shopping tax in the Australian
domestic market, in particular, how some big multinational companies, (for example Amazon)
respond to such tax policy taken by our government. Read the article carefully in answering the
following question
(using appropriate diagrams with reference to relevant evidence):
Critically analyse the arguments put forth, both for and against an online shopping tax on Amazon using
the above article. You may use other resources to support your argument
30 points
Question 3: Price of goods and good’s quality
(Learning Outcomes: ULO3/GLO4)
In economics, we have learnt that good’s price does matter. Given the budget constraint and
everything else remains the same, an individual consumer switches to relatively cheaper goods (also
known as substitution effect).
Often when you visit a chemist shop with your doctor’s prescription, your pharmacist may ask
whether you are interested in buying a relatively cheaper drug (which is biologically equivalent to
your prescribed drug) if it is available. Read the article carefully titled “Economists throw doubt on

generic drug price advantage over branded version”.1 Explain what seems to be a problem that may
arise when one switches to a cheaper drug
(using appropriate diagrams with reference to relevant
10 points
5 points will be allocated to the quality of presentation, including digital presentation of diagrams; all
labels and headings on diagrams; proper referencing; assignment submitted as a PDF document; and
quality of writing, taking the total to 100 points.
Your score out of 100 points will be converted to a grade out of 30 marks, or 30% of your final result for
the unit.
