About WJEC A Level Economics Resource Allocation
Resource allocation is a short WJEC AS microeconomics topic that explains how a free market economy decides what, how and for whom to produce. The answer is the price mechanism: changes in prices signal information, create incentives for producers and consumers and ration scarce goods. You should be able to show these functions on a demand and supply diagram and apply them to real markets, from food to housing. The topic links demand and supply analysis to market failure, which looks at where the price mechanism does not lead to the best outcome. It is examined in AS Units 1 and 2, often as a short explanation using recent data.
What you need to know
- How a free market works Resources are owned privately and allocated by voluntary exchange. Consumers spend according to their preferences and firms produce what earns them profit, coordinated by prices.
- Signalling Prices act as signals. A rising price tells producers that demand is strong or supply is short; a falling price signals that resources should move elsewhere.
- Incentives Higher prices make production more profitable, encouraging firms to expand output and attracting new entrants. Price changes also give consumers incentives to change what they buy.
- Rationing When a good becomes scarcer, its price rises, so it is rationed to those who value it most and can afford it, and the shortage is eliminated.
- Advantages of the price mechanism It works automatically without central planning, responds quickly to changes in tastes and costs, encourages efficiency and innovation and offers consumers choice.
- Limitations It ignores external costs and benefits, does not provide public goods, can lead to very unequal outcomes and may give volatile prices, which provides the case for government intervention.
Common mistakes in Resource Allocation
- Explaining the price mechanism without a diagram when one is asked for. Show the shift and the resulting shortage or surplus.
- Mixing up the functions. Signalling is about information, incentives are about motivation and rationing is about who gets the scarce good.
- Assuming free market outcomes are fair. Efficiency and equity are different, and the market rations by ability to pay.
- Writing that prices are set by firms in a free market. In a competitive market price is set by the interaction of demand and supply.
Try three Resource Allocation exam-style questions
1. Explain the rationing function of the price mechanism. (2 marks)
Show the mark scheme answer
When a good is scarce its price rises; so only those willing and able to pay the higher price obtain it, removing the excess demand.
2. Using a diagram, explain how the price mechanism would respond to a poor harvest of strawberries. (6 marks)
Show the mark scheme answer
Supply shifts left; excess demand at the original price; price rises, signalling scarcity; higher price rations strawberries to those willing to pay (contraction of demand); higher price encourages growers and importers to supply more (incentive function, extension of supply); new equilibrium with higher price and lower quantity; correct diagram.
3. State two reasons why the free market may lead to a misallocation of resources. (2 marks)
Show the mark scheme answer
Externalities are not reflected in prices; public goods are not provided; information gaps; monopoly power; inequality (any two).
Resource Allocation FAQs
What does WJEC A Level Economics Resource Allocation cover?
It covers how a free market allocates resources through the signalling, incentive and rationing functions of the price mechanism, and the advantages and limitations of this system.
Which unit is Resource Allocation examined in?
It is AS content, so it is examined in AS Unit 1 (Introduction to Economic Principles) and AS Unit 2 (Economics in Action). A2 Unit 4 assesses all A level content, so it can be drawn on again there.
What is the best way to revise resource allocation?
Practise applying the three functions to real markets in the news, such as energy, housing or concert tickets, drawing the diagram each time and explaining the sequence of changes.
