2.2 The Role of Markets in Allocating Resources
2.2.1 The Market System
- Definition: A system where buyers and sellers interact to exchange goods/services.
- Market Forces = Demand + Supply.
- Outcome: Prices adjust to balance demand and supply (market equilibrium).
- Market Disequilibrium:
- Excess Demand (Shortage): Price rises.
- Excess Supply (Surplus): Price falls.
Examples:
- Housing market → if demand > supply, house prices increase.
- Wheat surplus → prices fall until demand rises.

2.2.2 Key Resource Allocation Decisions
Scarcity forces economies to answer 3 Key Questions:
| Question | Meaning | Example |
|---|---|---|
| What to produce? | Decide which goods/services to make | Guns vs butter, luxury vs basic goods |
| How to produce? | Decide production methods (labour vs capital intensive) | Use more machines or more workers |
| For whom to produce? | Decide distribution → who gets goods/services | Affordable public education vs private schools |
- Consumers influence “what” through demand.
- Producers influence “how” through efficiency choices.
- Government + Market decide “for whom” via income, prices, and policies.
2.2.3 Introduction to the Price Mechanism
- Price Mechanism = Process where prices adjust to allocate resources.
- Functions of Price Mechanism:
| Function | Explanation | Example |
|---|---|---|
| Rationing | Scarce goods go to those willing/able to pay higher prices | Limited concert tickets go to highest bidders |
| Signalling | Prices signal information to buyers/sellers | Higher oil prices signal producers to drill more |
| Incentives | Higher prices encourage more supply; lower prices encourage more demand | Rising wheat prices → farmers plant more wheat |
| Allocating | Resources move to most profitable uses | Workers shift to IT sector where wages are higher |
- Key Idea: Price mechanism answers what, how, for whom.
- Market efficiency achieved if no intervention (though real-world markets often fail).

Quick Examples for Exams
- If smartphone demand rises → price increases → producers make more smartphones → allocates resources to phones.
- In a drought, water price rises → rationing ensures only essential uses.
- A shortage of doctors leads to higher wages → signals more students to study medicine.
Memory Hooks
- 3 Questions: What? How? For whom?
- 4 Functions of Price Mechanism: Rationing, Signalling, Incentives, Allocating (RSIA).
- Market = buyers + sellers; Price = guide to resource use.
