The economy’s initial equilibrium is at E1. The most likely explanation for the move of the economy from its initial equilibrium at E1 to a new short-run equilibrium at E2 is a decrease in the A level of tariffs on imports. B productivity of capital. C rate of wage inflation. D value of government subsidies to farmers. [1 mark] 0 5 Which one of the following policies is most likely to improve the supply side of the economy? A policy which A increases the budget surplus. B reduces the natural rate of unemployment.

If the price elasticity of demand for the drink is –2.0, the price must have increased by A 5p B 10p C 15p D 20p [1 mark] 0 7 The hypothesis of diminishing marginal utility A assumes that at least one factor of production is fixed in the short run. B can be used to help explain why a demand curve is downward sloping. C explains why firms try to maximise profit. D states that total utility must fall as consumption increases.

Her final choice is between two cars which are identical in all respects except for the differences shown below. Period of Price guarantee against faults Car 1 £8 000 3 months Car 2 £10 000 12 months Based on the above information, which one of the following is the most likely explanation for the customer’s purchase of Car 2?

D wants to reduce the risks from asymmetric information. [1 mark] 0 9 All other things being equal, if the velocity of circulation is constant, the quantity theory of money based on Fisher’s equation of exchange, MV=PQ, predicts that an x% increase in the money supply will always cause an x% A decrease in the rate of interest. B increase in nominal national income. C increase in real national income. D increase in the rate of economic growth. [1 mark] 1 0 The diagram below shows the aggregate demand (AD) curve, the short-run aggregate supply (SRAS) curve and the long-run aggregate supply (LRAS) curve for an economy. The economy’s initial equilibrium is at E1. The government wants to achieve economic growth without conflicting with its long-run objective of price stability. All other things being equal, which one of the following policy combinations is most likely to enable the economy to achieve a new long-run equilibrium at E2? A A reduction in interest rates and increased government borrowing. B A reduction in the budget deficit and the rate of growth of the money supply. C Increased government expenditure on apprenticeships and transport infrastructure funded through borrowing. D Increased government expenditure on welfare funded through higher indirect taxes.

A £15 B £105 C £110 D £120 [1 mark] 1 2 The existence of negative externalities in consumption results in a misallocation of resources. This is because at the free market level of output the A marginal private benefit is greater than the marginal private cost. B marginal private cost is greater than the marginal social cost. C marginal social benefit is less than the marginal social cost. D marginal social cost is less than the marginal private benefit.

The kinked demand curve model provides an explanation of why the A firm colludes with competitors to set the price of 0P1. B firm’s demand curve becomes more elastic as it lowers its price.
