← Market structures and marginal analysis

How this connects to the other Level 3 Economics standards

Marginal analysis and the efficiency judgement here are the same tools 91403 uses at the whole-economy level — only the scale changes.

Shared ideas across the Level 3 Economics externals

  • Allocative efficiency (P = MC) here is a firm-level version of the same efficiency concept 91403 applies to whole markets and government policy.
  • The normal-profit-as-a-cost distinction is the same "opportunity cost" thinking used throughout the subject — a resource is only truly "free" if it has no next-best alternative use.
  • Comparing two policy or market outcomes (regulation vs no regulation, marginal-cost vs average-cost pricing) is the same compare-and-contrast skill 91403 rewards when comparing two macroeconomic policy responses.

Why this matters for revision order

The graph-labelling discipline this standard demands (naming "Graph One" explicitly, shading exactly what is asked) is good practice for any economics external that supplies a diagram — carry the habit across, not just the content.
