Perfectly elastic curves are horizontal.
Perfectly elastic curves are horizontal.
question
The price elasticity of demand for a brand of breakfast cereal is 5.
Based on this elasticity, what will be the percentage change in the quantity of breakfast cereal bought as a result of a %5 decrease in the cereal's price?
Based on this elasticity, what will be the percentage change in the quantity of breakfast cereal bought as a result of a %5 decrease in the cereal's price?
answer
+25%
The 5\%5%5, percent decrease in price will cause quantity demanded to increase by 555 times more than the change in price (since the elasticity coefficient is -5−5minus, 5). This means quantity demanded increases by 25\%25%

question
What happens to price elasticity of demand as the price of a good increases along a linear demand curve?
answer
Price elasticity of demand increases.
As you move to the left along a linear demand curve, the price elasticity of demand increases. Even though the slope of a linear demand curve is constant, elasticity is not.

question
If the price elasticity of demand is unit elastic how does quantity demanded change in response to a %25 increase in price?
answer
Quantity demanded decreases by 25%
Unit elasticity means that a change in quantity demanded will equal the magnitude of change in price, so a 25%, percent increases in price decreases quantity demanded %25.
Unit elasticity means that a change in quantity demanded will equal the magnitude of change in price, so a 25%, percent increases in price decreases quantity demanded %25.
question
Which of the following best describes what price elasticity of demand measures?
answer
How responsive buyers are to a change in the price of a good
Elasticities measure a response to a change in some factor, such as price or income. Price elasticity of demand measures how quantity demanded changes (the response) caused by a change in price (the factor that is changing).

question
Total Revenue Rule
answer
if you increase the price of a good with inelastic demand, then total revenue increases
question
Which of these values of price elasticity will result in no change in total revenue if a firm increases its price?
answer
1
A price elasticity of demand equal to 1 indicates unit elasticity. When a firm has a demand that is unit elastic, any increase in price is offset by an equal decrease in quantity and, as a result, total revenue doesn't change.

question
When is demand inelastic?
answer
When there are few substitutes for a good
