Some 25 marker possibilities I have been planning/researching based on the advanced information:
- assessing contestability in a market of your choice
- government intervention to increase contestability
- government intervention in market structures (oligopoly, monopoly)
- business growth (benefits/drawbacks of different types and maybe government intervention, possibly to what extent is XYZ a constraint on business growth)
- comparing business objectives in different markets - for example evaluate that profit maximisation is the primary objective in an industry of your choice (or specific market structure)
- efficiency - maybe discussing efficiency in different markets like evaluating that a monopoly is always inefficient (can't think of better wording off the top of my head)
- Market structures and their impacts on consumers/suppliers/employees/firms
- Maybe market structure and reasons for non-competitive behaviour but not sure how that would be worded honestly
- And possibly government intervention + externalities
All points above discussing government intervention could consider government failure too
It looks like a lot but many of them link together/overlap significantly - research on one industry area could be applied to lots of different questions!
General application areas that could come up are energy markets, enviromental policies, general policies to reduce externalities, mergers/acquisitions in an industry and
almost definitely a reference to oligopolies/monopolies in some form. For the labour market - labour supply factors/immobility is on the advanced information but I don't think it will be a 25 marker as it was already asked in 2019 and 2021 but don't take my word for that
