Questions from this subtopic
Each one with the model answer underneath.
- 1
How do high barriers to entry shape market structure?
Model answer
They keep the number of firms small and protect incumbents' profits, so the market tends towards oligopoly or monopoly.
- 2
What happens to market structure when barriers to entry fall?
Model answer
New firms enter, concentration falls, prices are competed down and the market moves towards imperfect or perfect competition.
- 3
What are economies of scale?

Economies of scale are the reductions in long-run average cost that come from producing on a larger scale.
- 4

What are purchasing economies of scale?
Model answer
A large buyer orders in bulk and negotiates a lower price per unit from suppliers, which cuts the cost of every item it sells.
- 6
What are technical economies of scale?
Model answer
Larger plant and specialised machinery spread capital costs over more units and allow processes that would be too big for a small producer.
