1(a) Identify two ways in which kiranas compete for customers. 2 Must be distinct points: • exotic / fresh produce / quality • government intervention • prime locations • credit facilities • home delivery • sourcing products not normally stocked • local knowledge 2 × 1 marks 1(b) What can be concluded about the groceries and vegetables trade in 5 India from Fig. 1.1? Candidates can write about the type of store and / or the composition of the grocery / vegetable trade. For example: • Online grocers least used, more for groceries than vegetables • Stalls and kiranas most used, vegetables the most common closely followed by grocery and vegetable sales, relatively few groceries-only customers • Supermarkets the second most-used with limited vegetables sales • Home delivery kirana customers more grocery-heavy, in contrast to those who visit the shops and stalls. 5 × 1 mark, based on Fig. 1.1 1(c) Use economic analysis to suggest the market structure in which kiranas 6 operate and explain how equilibrium is reached by a firm in such a market. 1 mark for identification of Monopolistic Competition Up to 2 marks for explanation / characteristics Up to 3 marks for analysis of Monopolistic Competition short run or long run equilibrium. If wrong market structure identified allow up to 3 marks for analysis of short run or long run equilibrium of the market chosen. Diagrams are not essential. 1(d) Discuss how it might be possible for supermarkets in India to compete 7 with the stalls and kiranas. Up to 4 marks for analysing why it might be possible: • Supermarkets can enjoy economies of scale, reduces LRAC and therefore prices allowing them to compete. • For example can spread the cost of advertising across multiple stores to increase their demand, can buy products in bulk and so enjoy lower unit costs, can use specialisation of labour. • Credit facilities, delivery quality. Up to 4 marks for analysing why it might not be possible: • Many good sites already occupied by kiranas, therefore a barrier to location. • Small shops compete on knowledge, convenience and personal relationships, hence still attract consumers. • Large proportion of India’s population lives in rural villages and may be many kilometres from supermarkets. • Average incomes for many are low therefore idea of weekly / monthly shop is limited and therefore limits supermarket demand. 1 mark for a conclusion. NOTE: max. 7 marks Section B: Essays The Essays are to be assessed using the Levels of Response approach, process and generic grid of descriptions. The descriptions in the grid are generic so that answers to all Essays are assessed against a common set of criteria. The mark scheme for the Essays includes indicative content describing the likely approaches and relevant arguments candidates may make in their answers, but there will be a variety of relevant, valid responses seen. The mark scheme also includes the mark bands to be used for each level for each question.

3(a) A recent newspaper article commented on the fact that a pharmaceutical 12 company charged customers in the United States (US) US $800 per treatment whilst it charged customers in Egypt US $80 for the same treatment. Explain why the company might follow this policy and what conditions are necessary to allow the policy to be successful.

4(a) Analyse how an individual consumer’s demand curve for a product is 12 derived and consider how this may be linked to its market demand. Candidates can use either a marginal utility or an indifference curve approach. Marginal Utility: explanation of marginal and total utility, the equi-marginal equilibrium, the change in price of one good and the resultant establishment of the new equilibrium and its consequence for demand. Indifference Curve: explanation of the shape of an indifference curve and a budget line, the point of tangency to establish demand, followed by a change in price and change in quantity, linked to an individual’s demand curve. The aggregation of individual’s demand curves to make the market demand curve. L4 (9–12 marks) For a sound explanation of marginal utility, and the link to equi-marginal equilibrium. The effect of a change in price on demand for a good linked to an individual demand curve and hence the aggregation of individual demand to construct a market demand curve. Or For an accurate analysis of an indifference curve map and budget line tangency. Change in price shifting budget line and impact on individual demand curve and hence the aggregation of individual demand to construct a market demand curve. L3 (7–8 marks) For a sound explanation of marginal utility, and the link to equi- marginal equilibrium. The effect of a change in price on individual demand. Or For an accurate analysis of an indifference curve map and budget line tangency. Change in price shifting budget line and impact on individual demand curve. L2 (5–6 marks) For a limited explanation of equilibrium. Or For an explanation of an indifference curve map and budget line tangency. L1 (1–4 marks) For an answer which has some basic correct facts but includes irrelevancies. Errors of theory or omissions of analysis will be substantial. 4(b) Use indifference curve analysis to distinguish between the effect of an 13 increase in income on a consumer’s demand for a normal good and an inferior good.

5 Cyclical and structural unemployment are the most common types of 25 unemployment. Explain the causes of these types of unemployment and assess the effectiveness of government policies to reduce them. An analysis of the cause of cyclical unemployment – lack of aggregate demand and structural unemployment – a lack of demand for a particular good or service. Fiscal, monetary and supply-side policies need to be identified and analysed and linked to the structural or cyclical unemployment.

6(a) The US Federal Reserve pursued a policy of quantitative easing (QE) for 12 several years. Explain how the quantitative easing affects the level of economic activity in a country. The injection of money into the economy to boost spending. The central bank creates new money electronically to buy financial assets like government bonds. This cash injection lowers the rate of interest and boosts asset prices, which increases wealth and supports spending, increasing AD and stimulating employment and growth.

The links between the factors e.g. which leads to reinforcement of the individual effect. Max. 11 if no conclusion. L3 (7–8 marks) For a discussion of the contribution of the three factors health, education and savings mentioned above to economic development. and / or a limited discussion of other factors. L2 (5–6 marks) For a limited description of 2 of the 3 factors affecting economic development. Or A limited description of other factors.
