Here's what a star student thought of this essay
Quality of writing
The essay has a good structure, posing a strong introduction by defining the key terms. Similarly, the conclusion is strong by weaving together all the points to come to a strong argument that supply side policies are important. The style is fine, and technical terms such as natural rate of employment are used with confidence. Spelling, punctuation and grammar are fine.
Level of analysis
The analysis in this essay is sound, but there are places where improvements could be made. For example, the essay mentions "supply side policies focus on shifting the LRAS curve to the right" but at no point is a diagram included. Using diagrammatical analysis to show shifts and the effects will gain easy marks, as it shows a high level of skills. There is a lack in understanding shown when a diagram is not used, as a Keynesian curve would allow analysis of the different macroeconomic equilibria on the curve. A discussion of an increase in LRAS having an effect on inflation would've naturally led on if a diagram was used. I think the analysis is sometimes backwards, though in this essay. Saying "supply side policies may also affect labour productivity and unit labour costs." adds nothing to the argument. If I were doing this essay, I would be saying "A supply side policy is investment into education and training. This aims to increase labour productivity by providing the workforce with more skills". Being clear in economics is crucial, as it is so easy to swap the causes and suddenly the analysis makes no sense! If this essay wanted to go further, it could explore the limitations of supply side policies, but this isn't necessary given the task.
Response to question
This essay engages well with the question, exploring supply side measures. As there is no command word such as "discuss" or "comment", there is no need to mention the effectiveness or significance. But, I would note that this question is commonly asked in exams but with a focus on effectiveness, so this essay would not be as strong in that context. Nevertheless, this essay is fine as it explains the mechanisms well, exploring a variety of supply side measures.
