Here's what a star student thought of this essay
Quality of writing
There isn't much to structure here, as this is more of an overview and revision sheet than an argument. Bullet points are used well to differentiate between points, and technical terms are used throughout. Spelling, punctuation and grammar are fine.
Level of analysis
The analysis in here is sound. I liked the definition of unemployment, as this is a popular question and often the definition is confused. You must put "willing and seeking work" and this essay does this well. I would note that exams often like to catch people out by asking you to define the unemployment rate, this is as simple as quoting the definition and then adding the formula given in this essay! The types of unemployment are given a good overview, however I would've liked to have seen some diagrams showing shifts in aggregate demand, etc. Diagrammatical analysis is an easy way to pick up marks, as it shows a variety of skills and a strong understanding of what causes unemployment. The discussion of NAIRU is strong, as this is a concept which is commonly forgotten about or misunderstood. When talking about the costs of unemployment, it would be good if a PPF was included as this shows the misallocation of resources and waste of capacity. I always like to talk about the costs to the unemployed, as this can bring social problems. Hysteresis is a concept which examiners like, whereby the long term unemployed lose any skills or confidence making it harder for them to find work. As mentioned above, when talking about policies you really need to be clearer and discuss monetary and fiscal approaches.
Response to question
I liked this essay as it gives a good overview of unemployment, without getting bogged down in argument. This should be a good resource to look at for revision. The definition of unemployment is covered, the types are summarised, the costs are covered. The policies to reduce unemployment is poorly covered, however, as this should be looking at fiscal and monetary policies also. Trends are briefly looked at, but if you are preparing for an exam it would be wise to look at more recent data.
