Macroeconomists study
economy-wide phenomena.
Suppose that quantity demand falls by 30% as a result of a 5% increase in price. The price elasticity of demand for this good is
elastic and equal to 6.
Refer to Figure 5-4. The section of the demand curve from A to B represents the

If the price of Diet Coke rises, Jane decreases her consumption by only a very small amount. But if the price of gourmet cheese rises, Jane decreases her consumption by a lot.

inflation.
Marcus says that he would smoke one pack of cigarettes each day regardless of the price. If he is telling the truth, Marcus's
demand for cigarettes is perfectly inelastic.
If the quantity demanded of a certain good responds only slightly to a change in the price of the good, then the
demand for the good is said to be inelastic.
Whether a good is a luxury or necessity depends on the
preferences of the buyer.

2.33.
Last year, Tess bought 5 handbags when her income was $54,000. This year, her income is $60,000, and she purchased 7 handbags. Holding other factors constant, it follows that Tess's income elasticity of demand is about
