Hi,
Yes I have analysed past papers questions and I have now my predictions of the Unit 3 AQA Economics exam on June 20th:
Essays:
I fully believe that the first essay will be about business objectives, heavily referring to monopoly and perfect competition, but mainly about the growth of firms and how significant profit maximisation and other objectives to certain firms and market structures are.
I believe the second essay will be on either price discrimination (hasn't featured as second essay since June 2013) or contestable markets (which hasn't featured since June 2012).
Finally, the trend seems to say that the third essay will be a cost-benefit analysis one (as it comes up every 2 years: Jan 2010, June 2012, June 2014) but it's very likely it could be about poverty, however this came up last year as the 3rd essay (in the form of distribution of income).
For the contexts, I have no idea but the general structure is always should the government intervene and competition policy is strong for this.
Good luck to everyone!
