1(a) Identify one possible cause of the decline in world export prices of 1 Extract 1 contains possible causes. These maize. include supply factors such as large global supplies and good harvest prospects from For the identification of one possible cause (1 mark) South America and demand factors such as lower demand for maize from the biofuel and animal feed industries. The cause identified does not have to be confined to the data. Any valid demand or supply factor is acceptable provided it identifies why demand or supply may change. 1(b) Explain one change in a factor of demand that would lead to maize 2 Any appropriate demand factor can be prices rising in Malawi despite the increase in domestic production. accepted.

(1 mark) 1(c) With reference to extract 2 explain two reasons why maize prices are 4 Extract 2 states that the two reasons are rising in Zimbabwe despite the fall in the world export price of maize. ‘sustained weakness in Zimbabwe’s currency’ and the ‘sharply reduced For identification of a reason (1 mark) and for explanation of how this will harvest’. These need to be identified and cause prices of maize to rise (1 mark) explained. Only accept valid reasons contained in extract 2 that explicitly refer to Zimbabwe. The explanation should develop into why this reason will cause the price of maize to rise in Zimbabwe. Relevant diagrams should only be rewarded if used as part of the explanation. 1(d) Explain, with the help of a diagram, how a rise in the minimum price of 3 Two marks are available for an accurate maize in Malawi will encourage production. diagram showing a movement upward (rise) of the guaranteed price and the For a fully accurate S and D diagram that clearly shows a rise in the minimum extension in supply. The diagram must be price of maize and the increase in supply (2 marks) accurately labelled.

For an accompanying explanation that clearly explains that there has been a rise in the minimum price of maize and that this should increase its production If the diagram does not make it clear that because it will encourage farmers to produce more maize. (1 mark) this is a rise in the minimum price then a maximum of one mark should be awarded overall. 1(e) Discuss, with the help of a diagram, whether a subsidy on maize 4 The diagram should show a shift to the production will always benefit both the producers of maize and poorer right of the supply curve and a fall in price- households in Zimbabwe equally. benefitting consumers and the payment to producers shown as the vertical distance For an accurately labelled diagram that shows the shift to the right of the between the new supply curve and the old supply curve and the fall in equilibrium price that benefits the consumer supply curve at the new price.

The use of a diagram if accurate and correctly explained may be used in the explanation and rewarded accordingly.

3(a) Explain how a production possibility curve can be used to demonstrate 8 Candidates are likely to provide a diagram scarcity, choice and opportunity cost. although this is not essential if it is clear that the basis of a PPC is understood. For knowledge and understanding of a production possibility curve (Up to 2 marks) If a diagram is used to demonstrate e.g. a curve that shows the maximum level of output that an economy can knowledge and understanding without an achieve (1) given its current level of resources / technology (1) accompanying explanation then this is For application that demonstrates a clear understanding of what is meant by acceptable BUT it must be correctly scarcity (1) and explains how this would be shown on a PPC (1) labelled as 2 different goods (i.e., not X and Y or P and Q) and the curve itself For application that demonstrates a clear understanding of what is meant by must touch both axes for both marks. choice (1) and explains how this would be shown on a PPC (1) For application that demonstrates a clear understanding of what is meant by Scarcity is shown through the PPC as a opportunity cost (1) and explains how this would be shown on a PPC (1) production frontier and not a position outside the curve. Choice must be shown as a movement along the curve. Opportunity cost is shown as the next best alternative foregone as one product is sacrificed to produce the alternative. A diagram may be used to demonstrate scarcity, choice and opportunity cost but must be accompanied by appropriate explanation to gain marks. However, a diagram is not essential. The application for scarcity, choice and opportunity cost must be clearly separated. 3(b) Discuss the difficulties that might be encountered when adopting supply 12 Candidates need to show good side policies to expand the productive capacity of an economy and understanding of a range of supply side consider whether these difficulties can be overcome. policies that may expand the productive capacity of an economy and specifically, For an analysis of how supply side policies may be used to expand the they should be aware of the difficulties productive capacity of an economy and the difficulties encountered in associated with such policies including the adopting them.

4(a) An economy adopts a freely floating exchange rate. 8 Candidates need to demonstrate knowledge of the impact of varying Explain how this economy’s exchange rate is likely to be affected when inflation on exports and imports and the its inflation rate is much higher than inflation rates in its trading effect on the foreign exchange market. partners. Allow the first KU mark if the answer gives For knowledge and understanding of the meaning an exchange rate i.e., an example of the price of one currency the price of one currency in terms of another currency (1) and of a freely quoted against another one floating exchange rate i.e. it is determined by market forces of demand and supply for the currency (1), is not fixed by the government (1). (Maximum of 2 marks) For application that explains the effect of the lower overseas inflation rates as a rise in demand for imports (1) which will increase the supply of the domestic currency (1 ) and will lead to a fall / depreciation in the exchange rate (1) (Up to 3 marks) For application that explains the effect of the lower overseas inflation rates as a fall in demand for exports (1) which will reduce the demand for the domestic currency (1) and will also lead to a fall/ depreciation in the exchange rate (1).

Also, the lower price of For analysis that explains the disadvantages of a rise in the terms of trade imports mean that imported raw materials N.B. if only one disadvantage is discussed then maximum mark of 3 will fall in price and this will result in lower (Up to 4 marks) input costs.

Evaluative comment might refer to the significance of elasticities in determining the outcome. If the candidate is clearly confusing the terms of trade with the balance of trade or the budget balance throughout the answer, then 0 marks must be awarded. There are no KU marks awarded in part (b) for merely explaining / defining terms or phrases within the question.
