Elasticity - End of Chapter Problem The accompanying table lists the cross-price elasticities of demand for several goods, where the percentage quantity Cross-price change is measured for the first good of the pair, and the elasticities of Good demand percentage price change is measured for the second good. Explain the sign of each of the cross-price elasticities. Air-conditioning units and -0.34 What does it imply about the relationship between the two kilowatts of electricity goods in question? Coke and Pepsi +0.63 High-fuel-consumption sport-utility vehicles 0.28 a. The negative cross-price elasticity for air conditioning (SUVs) and gasoline units and kilowatts of electricity, and for SUVs and Mcdonald's burgers and Burger King burgers +0.825 gasoline, means they are Butter and margarine +1.54 The positive cross-price elasticity for Coke and Pepsi. Mcdonald's and Burger King burgers, and butter and margarine means they are b. Compare the absolute values of the cross-price elasticities and explain their magnitudes. For example, why is the cross-price elasticity of Mcdonald's burgers and Burger King burgers less than the cross-price elasticity of butter and margarine? O Since the cross-price elasticity of butter and margarine is larger than the cross-price elasticity of Mcdonald's burgers and Burger King burgers, butter and margarine are closer substitutes than are Mcdonald's and Burger King burgers. Since the cross-price elasticity of butter and margarine is larger than the cross-price elasticity of Mcdonald's burgers and Burger King burgers, Mcdonald's and Burger King burgers are closer substitutes than are butter and margarine. c. Use the information in the table to calculate, to two decimal places, how a 5% increase in the price of Pepsi affects the quantity of Coke demanded. The quantity demanded will change by d. Use the information in the table to calculate, to one decimal place, how a 10% decrease in the price of gasoline affects the quantity of SUVs demanded. The quantity demanded will change by
