11. Income elasticity measures the effect of a change in income on the purchases of some good or service.
12. The more time consumers have to adjust to a change in price,
a. the smaller will be the price elasticity of demand.

a. It is unit elastic.
b. It is price elastic.
c. It is price inelastic.
d. It is perfectly inelastic.
15. An income elasticity coefficient of −1.8 means the product is a normal good.
16. Supply curves tend to be
a. perfectly elastic in the long run because consumer demand will have sufficient time to adjust fully to changes in supply.
b. more elastic in the long run because there is time for firms to enter or leave the industry.
c. perfectly inelastic in the long run because the law of scarcity imposes absolute limits on production.
d. less elastic in the long run because there is time for firms to enter or leave an industry.
