2 ‘Free markets make the most efficient use of resources and are the 25 foundation of a successful economy.’ To what extent do you agree with this? A definition of a free market and the concepts of productive and allocative efficiency. Discussion of reasons for market failure, Imperfect knowledge, inequality, friction within a market, externalities. Note: All types of efficiency together to be regarded as one type of market failure. L4 (18–25 marks): For a thorough discussion which covers a good understanding of productive and allocative efficiency produced by markets. A good explanation of 2 forms of market failure which consider the impact on efficiency. A conclusion will be drawn that refers to a successful economy. (Max. 21 no conclusion). L3 (14–17 marks): For a competent discussion of productive and allocative efficiency produced by perfect markets. A limited explanation of 2 forms of market failure. L2 (10–13 marks): For an accurate though undeveloped explanation of efficiencies or market failures. L1 (1–9 marks): For an answer which shows some knowledge but does not indicate that the question has been fully grasped, or where the answer contains irrelevancies and errors of theory.

3(a) Explain what is meant by a normal good and comment on the link between 12 total utility, marginal utility and a consumer’s demand curve for that good. Definition of a normal good, explanation of total utility and links to total consumption. Derivation of falling marginal utility as consumption increases linked through equi-marginal consumption and price change of a product to the demand curve. L4 (9–12 marks): For clear explanations of the three terms and reference to the demand for a good. Establishment of the equi-marginal rule MUx/Px = MUy/Py. The effect of a change in price of a good on the ratio and the need to adjust the quantity demanded and hence MU in order to return to equilibrium must be explicitly stated. L3 (7–8 marks): For clear explanations of two of the terms and reference to the demand for a good. Establishment of the equi-marginal rule MUx/Px = MUy/Py. L2 (5–6 marks): For a clear explanation of 2 of the terms and an attempt to link it to the demand curve. 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. 3(b) Discuss how a government’s policies toward income and wealth distribution 13 can affect a consumer’s demand. A consideration of the impact of taxation, government transfer payments and/or other government policies on income and wealth and hence the budget line and demand. Consideration of the effect of taxation on wealth and the consumption effects of changes in wealth. Consideration of the difference in the income effect for normal and inferior goods. L4 (9–13 marks): For a response that explains two policies and their impact on income and wealth linked to consumer demand for normal goods and inferior goods. (No conclusion maximum 11). L3 (7–8 marks): For a response which explains two policies and the effect on income or wealth. Either normal or inferior goods are considered. L2 (5–6 marks): For a response which explains one policy with limited reference to demand. 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(a) Explain how a firm maximises its profit in perfect competition. 12 An explanation of the profit maximising rule based on MC = MR. Explanation of how when MC and MR are unequal a firm changes its level of output to increase profits. L4 (9–12 marks): For a sound explanation of increasing output when MC is less than MR and reducing output when MC is greater than MR to bring equilibrium when MC = MR. L3 (7–8 marks): For an explanation of equilibrium increasing output when MC is less than MR or reducing output when MC is greater than MR to bring equilibrium when MC = MR. L2 (5–6 marks): For an explanation of equilibrium when MC = MR. 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) Discuss whether profit maximisation is the best strategy in the long run for 13 firms in different market structures. A comparison of long-run profit and the difference that exists between the different forms of competition. Idea of contestable markets may mean that profit maximisation cannot be achieved due to hit-and-run competition, or there may be other objectives. Different strategies can be identified in relation to different market structures, e.g. in perfect competition and monopolistic competition long-run profit maximisation would apply, whereas in oligopoly and monopoly other strategies may be appropriate, e.g. sales revenue maximisation. L4 (9–13 marks): For a sound discussion of two market structures and two strategies. (Max. 11 if no conclusion). L3 (7–8 marks): For an analysis of either two market structures and one strategy or one market structure and two strategies. L2 (5–6 marks): For a limited comparison of a strategy between two forms of competition. 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.

5(a) Explain the relevance of economic rent and transfer earnings when 12 comparing the wages of skilled workers and unskilled workers. Definitions of economic rent and transfer earnings. Supply and demand factors in determining wage levels. The relevance of elasticity of demand and supply in the labour market. Application to skilled and unskilled workers. L4 (9–12 marks): For an explanation of the meaning of economic rent and transfer earnings and how these may differ between markets. Factors affecting the demand for labour and the supply of labour and their effect on the wages of skilled and unskilled workers. The relevance of elasticity of demand for and supply of labour. L3 (7–8 marks): For an explanation of the meaning of economic rent and transfer earnings and how these may differ between markets. Factors affecting the demand for labour and the supply of labour or elasticities of supply and demand for labour and their effect on the wages of skilled and unskilled workers. L2 (5–6 marks): For an explanation of the meaning of economic rent and transfer earnings and how these may differ between markets. 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. 5(b) Discuss whether workers always benefit when their trade union achieves an 13 increase in wages. Discussion and analysis of wage theory in imperfectly competitive labour market. Trade unions influence on wage rates; the negotiation of a higher wage. Examples could include minimum wage, higher labour productivity (higher MRP) and monopsony. L4 (9–13 marks): For a discussion of two ways in which trade unions may increase wages and of the extent to which each of these benefits the workers. (Max. 11 if no conclusion) L3 (7–8 marks): For a discussion of one way in which trade unions may increase wages and of the extent to which this benefits the workers. L2 (5–6 marks): For a discussion of one way in which trade unions may increase wages. 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. Alternatively, candidates may discuss a range of economic factors which reduce the benefits of an increase in wages e.g. higher taxation, inflation, working conditions. L4 (9–13 marks): For a discussion of 3 well explained economic factors. (Max. 11 if no conclusion). L3 (7–8 marks): For a discussion of 2 well explained factors or 3 less well explained factors. 5(b) L2 (5–6 marks): For a discussion of 1 well explained factor or 2 less well explained factors.
