【题目】

Answer two questions. Each question is worth [25 marks]. Write your answers in the boxes provided.
1. The table below shows data for price elasticity of demand and income elasticity of demand for seven product groups in Argentina in 2008.

There are concerns about rising food prices and their impact on households. Economists have forecast that rising food prices may have a negative effect on the demand for goods in other product groups.
(a) Outline one reason why
(i) the price elasticity of demand figures are negative;

(ii) the income elasticity of demand figures are positive.

(b) Using the price elasticity of demand data in the table
(i) calculate the percentage change in quantity demanded for clothing and footwear if the price of clothing and footwear rises by 6 %;

(ii) calculate the percentage change in the price of house furnishings that can lead to a 2 % fall in quantity demanded of house furnishings;

(iii) describe what might happen to the revenues of food and beverages firms as the price of food and beverages increases.

(c) The cross price elasticity between housing and house furnishing was estimated to be equal to – 0.4. Using this cross price elasticity data, explain the possible impact that an increase in house prices might have on the demand for house furnishing.

(d) Using the income elasticity of demand data in the table
(i) calculate the percentage change in quantity demanded for housing if household incomes rise by 4 %;

(ii) calculate the percentage change in household incomes that can lead to a 5 % rise in quantity demanded of recreation.

(e) Argentina’s average household disposable income is currently US$11 132 and household incomes are expected to grow in the future. The average Argentinean household income is forecast to rise by 27 % by 2015.
(i) Calculate the amount the average Argentinean household currently spends on health care.

(ii) Calculate the forecasted average Argentinean household income for 2015.

(iii) As a result of the forecasted average Argentinean household income for 2015,calculated in part (ii), explain what you would expect to happen to the proportion of income Argentinean households spend on health care.

【答案解析】

(a)

(i)As price increases, the quantity demanded decreases, and vice versa.So there is a negative relationship between price and quantity demanded sinceif price increases the willingness and ability to purchase the good decreases.

(ii)As income rises, households are more willing and able to purchasegoods. And because the goods in the table are normal goods, the quantitydemanded rises.

(b)

(i)-0.71 = % change in Qd / 6: % change in Qd = - 4.26 ( a decrease of4.26%)

(ii)-0.77 = -2 / % change in price: % change in price = 2.60 ( anincrease of 2.6%)

(iii)As the price of food and beverages increases the revenue of food andbeverages firms increases because demand is price inelastic so the increase inprice leads to a proportionately smaller decrease in quantity demanded.

(c) As the price of houses increases thedemand for house furnishings will decrease as they are complementary goods.Hence, as houses become more expensive, fewer will be bought and fewer housefurnishings will be needed. The increase in the price of houses will cause asmaller decrease in the demand for house furnishings.

(d)

(i)1.07 = % change in Qd / 4%: % change in Qd = 4.28 ( an increase of4.28%)

(ii)1.41 = 5 / % change in income: % change in income = 3.55 ( anincrease of 3.55%)

(e)

(i)0.09 x 11132 = $1,001.88

(ii)11132 x 1.27 = $ 14,137.64

(iii)The income elasticity of demand for health care is greater than 1,which means the demand for health care rises faster than income as incomerises; as a result, households will be spending a higher proportion of theirincome on health care over time.
