Write an essay of no more than 1200 words (no headings or sections) on the following scenarios and questions

Assume a country in which many people use vapes containing nicotine. There are health concerns because of this.

Researchers estimate that :

Supply of Vapes is given by: QS = 0.1P - 2

And

Demand for Vapes is given by: QD = 40 – 0.05P

P isin pence per millilitre [ml]    (eg P = 100:  = 100 pence/ml  = £1/ml) and:

Qs and QD are quantity of vape (in thousands of litres) supplied/demanded in the country per year

Assume:

•    all vapes are homogenous (no variation in active content)

• the vape market is competitive, and all producers are price takers.

1.  Create and explain a diagram showing Demand and Supply curves and showing

market-clearing Price (P) and Quantity (Q) and Producer Surplus (PS) and Consumer Surplus (CS).

[10%]

The Government imposes a tax on sales (paid by the seller) of Vapes at a fixed rate of 150

pence per ml of vape

2.  Create a diagram showing how this tax changes the market-clearing equilibrium.    Explain (in terms a non-economist can understand) if / how the tax changes supply and demand curves.

[10%]

3.  Create a diagram showing the changes in P, Q, PS, CS and Tax Revenue after the tax has been imposed. Calculate and explain:

•    price paid by consumers and price received by producers

•    changes in PS and CS at equilibrium.

Explain the diagram (in terms a non-economist can understand)

[20%]

4.  Critically discuss the impact of the tax, highlighting strengths and weaknesses. What effects, in addition to those shown in your diagrams, might occur because of its

imposition.

[25%]

Researchers discover the relationship between price and demand for vapes used above is incorrect, in fact the Q demanded is given by:

QD = 80 – 0.1P

5.  Create a diagram showing (the changes in) demand curve, P, Q and PS, CS and Tax Revenue after the tax has been imposed.

Explain how and why this change will affect the tax incidence compared to the initial result.

[25%]

[10%] will be awarded for the quality of the writing and structure.

Note 1: Reading

This is an opportunity to develop and exhibit your understanding of, and ability to explain, Econ concepts.

We are not expecting you to do a huge amount of additional research on the topics covered by the essay. Some additional research/reading could inform your answer to Q4.

The expectation is that you use the concepts and frameworks covered in Micro I, especially Core Units 8 and 10, lectures 13-15, Tutorial 6.

Note 2: Diagrams

Your diagrams must be electronically produced (see FAQ below).

They can either be precise (eg created in Excel) or schematic (like the example below) with the values approximately to scale (no difference in marking based on which type you use).

Q

Referencing Style

A full list of the references should be appended as a reference section. Use the Harvard Referencing style. This comprises:

1. In-text citation. Used when directly quoting or paraphrasing a source. They are in the body of the work and contain a fragment of the full citation. For example:

"After that I lived like a young rajah in all the capitals of Europe … " (Fitzgerald, 2004).

2. Reference  List. At the end of the work which displays full citations for all

sources used. For example:

Fitzgerald, F. (2004). The great Gatsby. New York: Scribner.

Marks will be deducted for not following this referencing format.

Proofread your work

Proofreading is an essential part of the writing process.

It is the final step you need to take to ensure that you are communicating your ideas clearly and to ensure that you are fulfilling the goals of your writing.

It is more than merely a spell check. It should involve double-checking your work against any criteria you have, making sure your references are accurate, your analysis sound, and clarifying any remaining questions or limitations of your work.
