Sorry if this is a bit of a late post, but I'm new here and posted my original post in a different thread by accident! Here's my post:
I severely regret doing the 'non-market failure' question over a generic 'subsidy analysis' question (a weird combination of exam panic and interest/surprise at a 20 marker on firm behaviour overwhelmed me...), although I did have loads of ideas on econs/disecons of scale.
Conversely, I struggled to structure it as our teacher didn't expect a 20 marker that is not about market failure to crop up.
Anybody else in the same boat as me? Everybody else in my year - around 18 people - did q17 and everyone on reddit played it safe (although not many 6th formers are active on reddit, it was quite amusing that someone called me a 'f-ing madman.' )
