Market Structures Exam Questions

What this practice covers

Real past-paper questions, the answer key from the mark scheme, and the explanation that goes with it. Each one is marked the moment you pick, the correct option is shown whether or not you found it, and the full explanation opens either way. No account needed to answer them.

These questions are drawn from past Edexcel A-Level papers. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.

Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here

These are the errors that cost marks on market structures, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.

• Confusing allocative (P = MC) with productive (minimum ATC) efficiency.
• Treating X-inefficiency as productive inefficiency, X-inefficiency means costs sit above the cost curve entirely.
• Forgetting that monopolistic competition earns normal profit in the long run with excess capacity.
• Defining oligopoly by the number of firms rather than interdependence.
• Drawing the kinked demand curve without the discontinuity in MR, which is the entire point.
• Omitting one of the three conditions for price discrimination, usually preventing resale.
• Saying a concentrated market must be uncompetitive, ignoring contestability.
