So can anyone sum up the key basis of evaluation in the exam? My understanding is that you discuss a particular point, then you weigh up its costs and benefits and then argue the points which it depends on, e.g. 'the effectiveness of deregulation of a market to increase competetition heavily depends on other barriers to entry in the market too, such as strategic barriers to enrty'.
Would this be the correct way to evaluate? If not any advice?
