I'm trying to do 25 mark questions that could possibly come up in my exams. How would I go about writing a 25 marker for the differences between Monopolies and Oligopolies? Like sure there are the basics like pure monopolies having the whole market share and legal monopolies having 25% or more. Whereas Oligopolies are markets dominated by a few large firms and firms are interdependent on each other. But I can't think of how to give long chains of reasoning and good evaluations. I also can't use the way I normally do a final substantiated judgement. Conclusion, reasoning, however it depends on. If anyone has any advice or somewhere that has a structured answer it would be great help.
