Examiner's comment
In this question, candidates are required to calculate the total reduction in the UK’s GDP. There are two steps in the process. Firstly, candidates need to calculate the value of the multiplier. Secondly, they need to multiply this value by £20 million. There were a range of answers with many of the weaker responses demonstrating a lack of understanding of this key macroeconomic formula. This is a response that was awarded the full 4 marks for the correct answer. Make sure you know key formulas, such as how to calculate the multiplier. It is always worth showing your workings in case you make a mistake as marks can be awarded for the workings.

Notes from the mark scheme and report
- multiplier = 1/(1 - MPC) = 1/0.36 = 2.78
- 2.78 x £20m = £55.6m (allow £55m to £56m)
- 3 marks if 'million' is missing
- show working
- weaker answers did not know the multiplier formula
Quantitative skills: QS 1 (calculate, use and understand ratios and fractions); QS 9 (interpret, apply and analyse information in written, graphical tabular and numerical forms)
