The price elasticity of demand for a good is likely to be elastic​ . A. the budget share spent on the good.
B. the number of close substitutes for the good.
C. the available time during which consumers can adjust.
D. all of the above.

The price elasticity of demand for a good is likely to be elastic​ :

A. the greater the proportion of budget share spent on the good.

B. the greater the number of close substitutes for the good.

C. the longer the available time during which consumers can adjust.

Explanation:

Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.

Price elasticity of demand = percentage change in quantity demanded / percentage change in price  

If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.  

Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one

Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded.  

Infinitely elastic demand is perfectly elastic demand. Demand falls to zero when price increases  

Perfectly inelastic demand is demand where there is no change in the quantity demanded regardless of changes in price.

Price is more elastic in the long run than in the short run because consumers have more time to search for suitable alternatives

The more close substitutes a good has, the more elastic its demand. This is because if price is increased, consumers can easily shift to the consumption of an alternative product

the greater the proportion of budget share spent on the good, the more elastic the demand for the good
