• Please Note: You are permitted to upload your Coursework in the final submission area as many times as you like before the deadline. You will receive a similarity/originality score which represents what the Turnitin system identifies as work similar to another source. The originality score can take over 24 hours to generate, especially at busy times e.g. submission deadline. 

• If you upload the wrong version of your Coursework, you are able to upload the correct version of your Coursework via the same submission area. You simply need to click on the 'submit paper' button again and submit your new version before the deadline. 

In doing so, this will delete the previous version which you submitted and your new updated version will replace it. Therefore your Turnitin similarity score should not be affected. If there is a change in your Turnitin similarity score, it will be due to any changes you may have made to your Coursework. 

• Please note, when the due date is reached, the version you have submitted last, will be considered as your final submission and it will be the version that is marked. 

• Once the due date has passed, it will not be possible for you to upload a different version of your assessment. Therefore, you must ensure you have submitted the correct version of your assessment which you wish to be marked, by the due date. 

Your overall total word count should not exceed 2,000 words (Weighted at 30% of final mark for the module)

Question 1 

Consider the market for wheat in the UK. The market is at equilibrium e1 (Quantity Q1 and Price P1) as the demand for wheat intersects with the supply of wheat. The market is served by a combination of UK wheat production and imports of wheat from outside the UK. Assume that the Government imposes a total ban on wheat imports. 

a) Illustrate graphically (you need to use only one diagram - call it Figure 1) the market equilibrium point at e1 (see above) and the new equilibrium point at e2 (Quantity Q2 and Price P2) following the Government intervention. 

[15 marks] 

b) Discuss and explain the effects of a ban on foreign wheat on UK supply and demand. 

[15 marks] 

c) What is the difference between Quotas on imports and total Ban on imports? 

[05 marks] 

d) What is the aim of the Quotas on imports and total Ban on imports? 

[05 marks] 

Question 2 

You are given the following data (see Table 1) for a small company which produces bricks for house construction. 

a) Fill in Table 1 – there is an Excel Version of Table 1 and you are advised to fill in Table 1 in MS Excel and then copy and paste Table 1 from MS Excel to MS Word. Use one decimal point for your calculations. 

[04 marks] 

b) Illustrate graphically the Total Productivity (TP). Make sure you label the axes and the line. 

Call it Figure 2. 

[03 marks] 

c) Illustrate graphically on the same diagram, the Marginal Product of Labour (MPL) and the 

Average Product of Labour (APL). Make sure you label the axes and the lines. Call it Figure 3.

d) Discuss and critically evaluate the “law of diminishing marginal returns (or diminishing marginal product)”. As part of your discussion and critical evaluation, you may refer to the numbers, points of interest and trends of the completed Table 1 and Figures 2 and 3 to consolidate your arguments and discussion. 

[20 marks] 

e) Discuss the inter-relationship of the Total Productivity (TP), Marginal Product of Labour (MPL) and the Average Product of Labour (APL) using Figures 2 and 3. How are all these curves interrelated, and what they tell us about productivity when labour increases and capital remains constant? 

[10 marks] 

Question 3 

One of the main market paradigms discussed in Economics literature is the market of perfect competition. In your critical evaluation do you think that the perfect competition exist in the real world? Justify your answer by employing references from official sources.
