The price elasticity of demand measures the responsiveness of consumers to changes in price. For example, if consumers change their purchasing behavior very little in response to a drastic change in price, demand is said to be inelastic; but if consumers change their purchasing behavior a lot in response to a small change in price, demand is said to be elastic.
If a good has several close substitutes, then many consumers will respond to an increase in the price of the good by purchasing one of those close substitutes. For example, many people believe that Coke and Pepsi are close substitutes for each other. Therefore, holding the price of Pepsi constant, if the price of Coke were to increase, many consumers would decide to switch to Pepsi. Therefore, the demand for Coke is relatively elastic. By contrast, there are no close substitutes for insulin as a treatment for diabetes. As a result, an increase in the price of insulin will not lead to a noticeable decline in insulin consumption. The demand for insulin is relatively inelastic.

Since the percentage change in quantity is greater than the percentage change in price, the price elasticity of demand is greater than 1, and demand is elastic between points W and X.
Demand is unit elastic if the price elasticity of demand is equal to 1. This occurs when the percentage change in quantity demanded is equal to the percentage change in price. Using the midpoint method, the percentage change in price between points X and Y is 25%, and the percentage change in quantity between points X and Y is -25%. Since the percentage change in price is equal to the percentage change in quantity, the price elasticity of demand is 1, and demand is (approximately) unit elastic between points X and Y.
Demand is inelastic if the price elasticity of demand is less than 1. This occurs when the percentage change in quantity demanded is smaller than the percentage change in price. Using the midpoint method, the percentage change in price between points Y and Z is 111%, and the percentage change in quantity between points Y and Z is -43%. This means the price elasticity of demand equals 43%111%=0.3943%111%=0.39. Since the percentage change in quantity demanded is smaller than the percentage change in price, the price elasticity of demand is less than 1, and demand is inelastic between points Y and Z.
In general, demand tends to be elastic at relatively high prices, inelastic at relatively low prices, and unit elastic at prices toward the middle of the demand curve.

The price elasticity of demand measures the responsiveness of consumers to changes in price. For example, if consumers change their purchasing behavior very little in response to a drastic change in price, demand is said to be inelastic; but if consumers change their purchasing behavior a lot in response to a small change in price, demand is said to be elastic. An economist would say that the flatter demand curve is relatively elastic, whereas the steeper demand curve is relatively inelastic.
The previous graph shows the two most extreme types of demand elasticities: perfectly elastic and perfectly inelastic. Curve LL is perfectly elastic, as it indicates that quantity demanded is as responsive as possible to any given change in price. Intuitively, you can see this by observing that if price increases, quantity demanded falls to zero. On the other hand, curve OO is perfectly inelastic because no matter how much the price changes, quantity demanded is unaffected.
The price elasticity of demand is the percentage change in quantity divided by the percentage change in price. Using the midpoint method, the percentage change in quantity demanded for curve NN between points A and D can be computed as follows:

Because the elasticity is less than 1, demand is inelastic between points A and D. You can also see this by observing that the percentage change in quantity demanded is less than the percentage change in price between points A and D along curve NN.
Again, using the midpoint method, the price elasticity of demand between points A and C along curve MM is 35.29%18.18%=1.9435.29%18.18%=1.94. Because the elasticity is greater than 1, demand is elastic between points A and C. Therefore, curve NN is less elastic than curve MM for the specified regions.

The price elasticity of demand measures the responsiveness of consumers to changes in price. For example, if consumers change their purchasing behavior very little in response to a drastic change in price, demand is said to be inelastic; but if consumers change their purchasing behavior a lot in response to a small change in price, demand is said to be elastic.

Consumers will find it more difficult to minimize gas purchases in the short run than in the long run. For example, if you come out of your economics class to find that the price of gasoline has tripled, what are your options? If your car is low on gas, you have very few options. So, in the very short run, the demand for gasoline is extremely inelastic. If the price stays high for a few weeks, you may try to find someone to carpool with to class or you may cut down on the number of trips you make to the mall. If the price stays high long enough, you might continue to carpool and reduce your discretionary driving, but you might also decide to move closer to where you commute most or choose a more fuel-efficient vehicle. In the long run, people have more opportunities to find substitutes for or ways to reduce their use of gasoline-intensive transportation. Therefore, the quantity of gas demanded will be more responsive to changes in price in the long run than in the short run.

Recall that the price elasticity of demand between points A and B is 0.14. This means that the elasticity between these two points is less than 1. Therefore, demand is inelastic between these two points.
Total revenue is equal to price times quantity. When price increases by $25 per bike, quantity demanded decreases from 99 to 90 bikes per day, and total revenue rises from $2,475 to $4,500 per day. Holding everything else constant, an increase in price will increase total revenue, but a decrease in quantity will decrease total revenue. When demand is inelastic, such as between points A and B, the increase in price is large enough to more than offset the decrease in quantity. Therefore, the net effect is that total revenue rises.

When demand is inelastic, price and total revenue move in the same direction. This happens because inelastic demand means that consumers are not very sensitive to changes in price. Specifically, when price changes, the percentage change in quantity will be less than the percentage change in price. You can see this mathematically by examining the equation for price elasticity of demand when demand is inelastic:

Total revenue is equal to price times quantity. Because price and quantity move in opposite directions when you move along a demand curve, a price change will cause total revenue to move in the direction of whichever variable is overpowering.
When demand is inelastic, you know that the percentage change in price is larger than the percentage change in quantity. This means that total revenue will move in the same direction as the price change. Thus, when price increases, so does total revenue; when price decreases, total revenue decreases as well.
When demand is elastic, you know that the percentage change in price is smaller than the percentage change in quantity, because consumers are highly sensitive to changes in price. This means that price and total revenue move in opposite directions. Thus, when price decreases, total revenue increases; when price increases, total revenue decreases.
Finally, when demand is unit elastic, total revenue remains constant when the price changes in either direction because the change in quantity demanded is proportionately equal to the change in price.

Recall that the price elasticity of demand between points A and B is 3. This means that the elasticity between these two points is greater than 1. Therefore, demand is elastic between these two points.
Total revenue is equal to price times quantity. When price decreases by $10 per bike, quantity demanded increases from 20 to 30 bikes per day, and total revenue rises from $1,600 to $2,100 per day. Holding everything else constant, a decrease in price will decrease total revenue, but an increase in quantity will increase total revenue. When demand is elastic, such as between points A and B, the increase in quantity is large enough to more than offset the decrease in price. Therefore, the net effect is that total revenue rises.

Recall that the price elasticity of demand between points A and B is 0.69. This means that the elasticity between these two points is less than 1. Therefore, demand is inelastic between these two points.
Total revenue is equal to price times quantity. When price increases by $20 per bike, quantity demanded decreases from 42 to 36 bikes per day, and total revenue rises from $3,360 to $3,600 per day. Holding everything else constant, an increase in price will increase total revenue, but a decrease in quantity will decrease total revenue. When demand is inelastic, such as between points A and B, the increase in price is large enough to more than offset the decrease in quantity. Therefore, the net effect is that total revenue rises.

Horses = -1/-15 = 0.07 Normal

Clubs = 10/-15 = -0.67 Inferior

Diamonds = -36/-15 = 2.4 Normal

The intuition behind this result is as follows: If income increases by 1% in Cardtown, then there is a 0.07% increase in the quantity of horses demanded. You can use the same equation to calculate that the income elasticity of clubs is −0.67−0.67, and the income elasticity of diamonds is 2.42.4.
Using the income elasticity of demand, you can then categorize goods as either normal or inferior. When an increase in income leads to an increase in quantity demanded (or a decrease in income leads to a decrease in quantity demanded), the good is called a normal good. Therefore, goods with a positive income elasticity of demand are normal goods. Since horses have an income elasticity of 0.070.07 and diamonds have an income elasticity of 2.42.4, both of these goods are considered normal goods.
However, when an increase in income leads to a decrease in the quantity demanded (or a decrease in income leads to an increase in quantity demanded), the good is called an inferior good. Therefore, goods with a negative income elasticity of demand are inferior goods. Since clubs have an income elasticity of −0.67−0.67, this good is considered an inferior good.

When the Big Winner charges $200 and average household income is $50,000, it can fill 300 rooms per night at that price. However, if average household income increases to $60,000, the quantity of rooms demanded rises to 350 rooms per night.
The income elasticity of demand measures how much the quantity demanded of a good changes when there is a change in consumers' income. You can calculate the income elasticity of demand for Big Winner's hotel rooms by dividing the percentage change in quantity demanded by the percentage change in income:

Income Elasticity of Demand =
Percentage Change in Quantity Demanded / Percentage Change in Income

Using the income elasticity of demand, you can then categorize goods as either normal or inferior. When an increase in income leads to an increase in quantity demanded (or a decrease in income leads to a decrease in quantity demanded), the good is called a normal good. Therefore, goods with a positive income elasticity of demand are normal goods.
However, when an increase in income leads to a decrease in the quantity demanded (or a decrease in income leads to an increase in quantity demanded), the good is called an inferior good. Therefore, goods with a negative income elasticity of demand are inferior goods.
Because the income elasticity of demand is positive for Big Winner's hotel rooms, it is a normal good. (Note: The percentage change calculations in this problem do not use the midpoint method.)

When the Big Winner charges $200, it can fill 300 rooms at that price.
Total revenue is equal to price times quantity. Therefore, you can compute Big Winner's revenue at this price in the following way:
Total Revenue = Price×Quantity

$200*300 = 60000

By lowering its price to $175, Big Winner can fill 325 rooms. In this case, total revenue is $175 per room per night×325 rooms=$56,875 per night$175 per room per night×325 rooms=$56,875 per night, a decrease of $3,125.
When demand is inelastic, you know that the percentage change in price is larger than the percentage change in quantity. This means that total revenue will move in the same direction as the price change. Thus, when price increases, so does total revenue; when price decreases, total revenue decreases as well.
When demand is elastic, you know that the percentage change in price is smaller than the percentage change in quantity, because consumers are highly sensitive to changes in price. This means that price and total revenue move in opposite directions. Thus, when price decreases, total revenue increases; when price increases, total revenue decreases.
Because total revenue decreases when Big Winner decreases its price, it must be operating on the inelastic portion of its demand curve.
Another way to confirm this is by directly examining the price elasticity of demand for Big Winner's rooms. The price elasticity of demand measures the responsiveness of consumers to changes in price. For example, if consumers change their purchasing behavior very little in response to a drastic change in price, demand is said to be inelastic; if consumers change their purchasing behavior a lot in response to a small change in price, demand is said to be elastic.
The price elasticity of demand is the percentage change in quantity divided by the percentage change in price. If the Big Winner drops its price from $200 to $175 per night—a decrease of 12.5%—the quantity of rooms demanded increases from 300 to 325, an increase of about 8.3%:

Price Elasticity of Demand = Percentage Change in Quantity / Percentage Change in Price

Since the percentage change in quantity demanded is less than the percentage change in price, the price elasticity of demand is less than 1, and demand is inelastic in this region. (Note: The percentage change calculations in this problem do not use the midpoint method. )

When the Peacock charges $300, it can fill 200 rooms at that price.
Total revenue is equal to price times quantity. Therefore, you can compute Peacock's revenue at this price in the following way:

Total Revenue = Price×Quantity

$300*200 = $60,000

By lowering its price to $275, Peacock can fill 225 rooms. In this case,
total revenue = $275×225 rooms=$61,875 an increase of $1,875.

When demand is inelastic, you know that the percentage change in price is larger than the percentage change in quantity. This means that total revenue will move in the same direction as the price change. Thus, when price increases, so does total revenue; when price decreases, total revenue decreases as well.
When demand is elastic, you know that the percentage change in price is smaller than the percentage change in quantity, because consumers are highly sensitive to changes in price. This means that price and total revenue move in opposite directions. Thus, when price decreases, total revenue increases; when price increases, total revenue decreases.
Because total revenue decreases when Peacock decreases its price, it must be operating on the inelastic portion of its demand curve.
Another way to confirm this is by directly examining the price elasticity of demand for Peacock's rooms. The price elasticity of demand measures the responsiveness of consumers to changes in price. For example, if consumers change their purchasing behavior very little in response to a drastic change in price, demand is said to be inelastic; if consumers change their purchasing behavior a lot in response to a small change in price, demand is said to be elastic.
The price elasticity of demand is the percentage change in quantity divided by the percentage change in price. If the Peacock drops its price from $300 to $275 per night—a decrease of 8.3%—the quantity of rooms demanded increases from 200 to 225, an increase of about 12.5%:

Price Elasticity of Demand= Percentage Change in Quantity / Percentage Change in Price

Since the percentage change in quantity demanded is greater than the percentage change in price, the price elasticity of demand is greater than 1, and demand is elastic in this region.

The price elasticity of supply measures the responsiveness of producers to changes in price. If producers change their production and selling behavior very little in response to a drastic change in price, supply is said to be inelastic; on the other hand, if producers change their production behavior a lot in response to a small change in price, supply is said to be elastic.
The price elasticity of supply is the percentage change in quantity supplied divided by the percentage change in price. Supply is elastic when the price elasticity of supply is greater than 1. This occurs when the percentage change in quantity supplied is larger than the percentage change in price. Using the midpoint method, you can compute the percentage change in quantity and price between points W and X in the following way:

Since the percentage change in quantity is greater than the percentage change in price, the price elasticity of supply is greater than 1, and supply is elastic between points W and X.
Supply is inelastic if the price elasticity of supply is less than 1. This occurs when the percentage change in quantity supplied is smaller than the percentage change in price. Using the midpoint method, the percentage change in price between points Y and Z is 67%, and the percentage change in quantity between points Y and Z is 12%. This means the price elasticity of supply equals 12%67%=0.1812%67%=0.18. Since the percentage change in quantity supplied is smaller than the percentage change in price, the price elasticity of supply is less than 1, and supply is inelastic between points Y and Z.
In general, supply tends to be elastic at relatively low levels of output and inelastic at relatively high levels of output.
