Evaluation
Consider cost, opportunity cost, targeting (means-tested versus universal), stigma and take-up. Judge between all, some or no children.

Context 2

Commodity prices

Extracts: Average monthly world prices of potash and crude oil, · Competition in the potash market · Commodities markets: should governments intervene?

Q31Explain10 marks
Extract E (lines 1–2), states ‘Potash is one of three main fertiliser products which farmers use to increase their output before planting crops such as wheat.’
Explain the possible effects on the market for wheat of a fall in the price of a fertiliser such as potash.

TopicPrice determination in a competitive marketCommodity markets

Examiner insight

What to cover
Potash is a fertiliser, so a lower price reduces wheat farmers' costs. Supply of wheat shifts right, the price of wheat falls and quantity rises.
Diagram

Watch out
Explain the link between the two markets clearly.
Q32Assess25 marks
Extract F (lines 15-16) states that ‘Commodities are vital as the raw materials and energy sources to make finished products’.
Using the data in the extracts and your economic knowledge, assess whether market forces should be left to determine the price of commodities such as potash, oil and gas.

TopicPrice determination in a competitive marketCommodity markets

Examiner insight

What to cover
Market forces set prices through supply and demand and signal scarcity.
Diagram
Demand and supply diagram, or buffer stock diagram.
Evaluation
Commodity prices are volatile because supply and demand are price inelastic; market power (potash) and externalities (oil and gas) also cause failure. Judge using the extract data.
Watch out
Use potash, oil and gas from the extracts.
