25
How does the value of price elasticity of demand change along a linear demand curve?
The value of price elasticity of demand changes along a linear demand curve because the slope of the curve varies. It is more elastic at higher prices and less elastic at lower prices.
26
What is the difference between elasticity and slope?
Elasticity measures the responsiveness of quantity demanded to changes in price, while slope measures the change in quantity demanded for a one-unit change in price.
27
What does it mean for demand to be price inelastic?
Demand is not affected by changes in price
28
What is the difference between perfectly inelastic demand and price inelastic demand?
Perfectly inelastic demand means that the change in quantity is zero for any percentage change in price, while price inelastic demand means only that the percentage change in quantity is less than the percentage change in price
29
If price and quantity demanded change by the same percentage, then total revenue __.
stays the same
30
What is the relationship between price changes and total revenue?
Price changes can either increase or decrease total revenue
31
How does a change in price affect total revenue?
The relationship between price changes and total revenue depends on the price elasticity of demand.
32
Can you provide an example of price elasticity of demand?
One example of price elasticity of demand is when the price of a luxury item increases and the quantity demanded decreases significantly.
33
Insulin is an example of a good that has __ demand
perfectly inelastic
34
Give an example of price elasticity of demand.
An example of price elasticity of demand is when a reduction in price leads to an increase in quantity demanded and total revenue.
35
How does a price change affect total revenue?
It depends on the initial price and the elasticity of demand
36
What is the concept of total revenue?
The relationship between price changes and total revenue
37
How does price changes affect total revenue?
The relationship between price changes and total revenue depends on the price elasticity of demand. If demand is elastic, a decrease in price will increase total revenue, while an increase in price will decrease total revenue. If demand is inelastic, a decrease in price will decrease total revenue, while an increase in price will increase total revenue. If demand is unit elastic, a change in price will not affect total revenue.
38
When the price of a good or service changes, the quantity demanded changes in the __ direction.
opposite
39
What is total revenue?
The price per unit times the number of units sold
40
What determines the price elasticity of demand?
The availability of substitutes The amount of time buyers have to adjust to price changes The importance of the good in household budgets
41
What determines whether demand is more or less price elastic?
The availability of substitutes Time The importance of the item in household budgets
42
Can you give an example of price elasticity of demand?
One example of price elasticity of demand is when the price of a luxury car increases and the quantity demanded decreases significantly. Another example is when the price of a generic brand of cereal decreases and the quantity demanded increases significantly.
43
What is the concept of price elasticity of demand?
The relationship between availability of substitutes and price elasticity of demand
44
What does a negative cross price elasticity of demand indicate?
Complements
45
How are goods classified as substitutes or complements based on their cross price elasticity of demand?
By their cross price elasticity of demand
46
What is cross price elasticity of demand and what is its formula?
Cross price elasticity of demand measures the responsiveness of demand for one good to changes in the price of another good. The formula for cross price elasticity of demand is (% change in quantity demanded of good A / % change in price of good B).
