6 In the diagram, YL and YM show two budget lines for a consumer of a product, X, when its price changes. IC1 and IC2 are two indifference curves, representing the consumer’s preferences between product X and spending on other goods. spending on Y other goods E2 IC2 E1 IC1 O L M quantity of X What is not a valid statement? A Product X must be a Giffen good, since the consumer spends more on other goods after the price change. B The consumer has greater satisfaction at E2 than at E1. C The prices of other goods are assumed to be held constant when drawing the budget lines. D The shift from YL to YM represents a fall in the price of product X.

6 When the price of a good increases, which statement is correct according to the analysis that uses budget lines and indifference curves? A The income and substitution effects of the price increase will work in opposite directions in the case of a Giffen good. B The income effect of the price increase will result in reduced consumption for all goods. C The new equilibrium position will be where the new budget line meets the original indifference curve. D The price rise will be represented by a parallel shift inwards of the original budget line.

5 The diagram shows a consumer’s initial budget line is GH and a set of indifference curves IC1, IC2 and IC3 for goods R and S. The original equilibrium for the consumer is point X. The inflation rate is rising faster than money incomes. What will be the most likely new equilibrium for the consumer if all real income is spent? good R G B A X D IC2 IC1 C IC3 O H good S
