How does elasticity affect price?
The four factors that affect price elasticity of demand are (1) availability of substitutes, (2) if the good is a luxury or a necessity, (3) the proportion of income spent on the good, and (4) how much time has elapsed since the time the price changed. If income elasticity is positive, the good is normal.
What are the five types of price elasticity of demand?
There are five types of price elasticity of demand: perfectly inelastic, inelastic, perfectly elastic, elastic, and unitary. Price elasticity of demand can be calculated by dividing the percentage change in quantity demanded by the percentage change in price.

3 Types of Elasticity of Demand On the basis of different factors affecting the quantity demanded for a product, elasticity of demand is categorized into mainly three categories: Price Elasticity of Demand (PED), Cross Elasticity of Demand (XED), and Income Elasticity of Demand (YED).
What is elasticity and different types of elasticity?
Price Elasticity is the responsiveness of demand to change in price; income elasticity means a change in demand in response to a change in the consumer's income; and cross elasticity means a change in the demand for a commodity owing to change in the price of another commodity.
What is price elasticity of demand in economics?
Price elasticity of demand is the ratio of the percentage change in quantity demanded of a product to the percentage change in price. Economists employ it to understand how supply and demand change when a product's price changes.
What is price elasticity of demand with examples?
Examples of price elastic demand We say a good is price elastic when an increase in prices causes a bigger % fall in demand. e.g. if price rises 20% and demand falls 50%, the PED = -2.5. Examples include: Heinz soup.

What is elastic inelastic and unitary elastic?
If the formula creates an absolute value greater than 1, the demand is elastic. In other words, quantity changes faster than price. If the value is less than 1, demand is inelastic. In other words, quantity changes slower than price. If the number is equal to 1, elasticity of demand is unitary.
What are the different types of elasticity in physics?
Elastic Moduli can be of three types, Young's modulus, Shear modulus, and Bulk modulus. In this article, we will understand elastic moduli in detail.
How to determine the elasticity of demand?
Therefore, the elasticity of demand can be determined by the slope of the demand curve. Flatter the slope of the demand curve, higher the elasticity of demand.
What is the difference between elastic and inelastic demand?
Elastic demand is the one when the response of demand is greater with a small proportionate change in the price. On the other hand, inelastic demand is the one when there is relatively a less change in the demand with a greater change in the price. ADVERTISEMENTS:
What is the value of perfectly inelastic demand?
The numerical value for perfectly inelastic demand is zero (e p =0).
Why is the change in demand negative?
This is because of the reason that the relationship between price and demand is inverse that can yield a negative value of price or demand.
When the proportionate change in demand produces the same change in the price of the product, the demand is referred to
When the proportionate change in demand produces the same change in the price of the product, the demand is referred as unitary elastic demand . The numerical value for unitary elastic demand is equal to one (e p =1).
When a small change in price of a product causes a major change in its demand, it is called?
When a small change in price of a product causes a major change in its demand, it is said to be perfectly elastic demand. In perfectly elastic demand, a small rise in price results in fall in demand to zero, while a small fall in price causes increase in demand to infinity. In such a case, the demand is perfectly elastic or e p = 00.
Can elastic demand be applied to a real situation?
However, a small rise in price would resist consumers to buy the product. ADVERTISEMENTS: Though, perfectly elastic demand is a theoretical concept and cannot be applied in the real situation. However, it can be applied in cases, such as perfectly competitive market and homogeneity products.
1. Perfectly Inelastic Demand
Perfectly inelastic means demand is steady even though the price changes. Demand is fixed even though the price increase or decrease. The same quantity will be demanded despite the price.
2. Inelastic Demand
Inelastic means the demand changes in a small variation in response to a comparatively high variation in a price change. Product demand is inelastic when the price change has a minor effect on the quantity demand.
3. Unitary Elastic Demand
Unitary elastic demand means the demand changes in a similar proportion to a change in price. This is where the price decrease equally increases the demand, and a price increase equally decreases demand.
4. Elastic Demand
Elastic demand means the demand changes in a large variation in response to a comparatively small variation in a price change. Product demand is elastic when the price change has a greater effect on the quantity demand.
5. Perfectly Elastic Demand (Infinite Elasticity)
Perfectly elastic demand (infinite elasticity) means even a minor variation in the product price results in an infinite change in the quantity demanded. The demand is infinite only at a specific price. Even a slight change in the price will eliminate the entire demand for the product, resulting in zero demand.
What is the elasticity of demand?
The elasticity of demand measures the relative change in the total amount of goods or services that are demanded by the market or by an individual. The quantity demanded depends on several factors. Some of the most important factors are the price of the good or service, the price of other goods and services, the income of ...

5 other types of Elasticity of Demand
The effect of change in economic variables is not always the same on the quantity demanded for a product.
Conclusion
We can conclude the blog by stating the fact that the demand for a commodity is affected by several factors and the three main types of elasticity of demand explains the effect of those factors.
What is the price elasticity of demand?
Price elasticity of demand is an indicator of the impact on the demand for a product in relation to its price change. Some types of consumer goods show a higher price elasticity of demand than others. For example, non-essential goods have a high elasticity of demand, while essential goods or consumer staples have a low elasticity of demand.
What factors affect the price elasticity of demand?
Factors that affect the price elasticity of demand include the availability of competitive substitutes and the brand recognition of products.
Why are essential goods inelastic?
Electricity, gas, oil, and water are all relatively inelastic because consumers rely on these as necessities rather than luxuries. Also, keep in mind that the price elasticity of demand is very time-sensitive.
Why do hamburgers have a high elasticity of demand?
For example, hamburgers have a relatively high elasticity of demand because there are plenty of alternatives for consumers to choose from, such as hot dogs, pizza, and salads. Gasoline and oil, however, have no close substitutes and are necessary to power equipment and transportation. These have a low price elasticity of demand.
Why are more expensive goods more elastic?
More expensive goods also tend to be more elastic since consumers are more sensitive to purchases that take up larger proportions of their income. Within the category of consumer staples, the price elasticity of demand changes if the marketplace has responded by offering competitive substitutes or if the consumer is willing to accept ...
How does consumer goods affect how you spend your money?
These key factors impact how you spend your money. All consumer goods are governed by the laws of supply and demand, so every type of consumer good demonstrates the price elasticity of demand. However, this does not mean the relationship between demand and price is equal across all types of consumer goods. Some types of consumer goods display high ...
What are consumer staples?
Consumer staples are a sub-category of consumer goods that are regarded as essential products. Examples of this include food, beverages, and certain household goods. Consumers view these goods as primary and essential for life. These are the staples people are unable (or are unwilling) to eliminate from their budget.
Example
Let us suppose that price of a good falls from $10 per unit to $9 per unit in a day. The decline in price causes the quantity demanded to increase from 125 units to 150 units per day. The price elasticity of demand will be:
Types
The concept of price elasticity of demand can be used to divide the goods into three groups.
Formula
The formula for measuring the income elasticity of demand is the percentage change in demand for a good divided by the percentage change in income.
Example
A simple example will show how income elasticity of demand can be calculated. Let us assume that the income of a person is $4000 per month and he purchases six CD’s per month. Let us assume that the monthly income of the consumer increase to $6000 and the quantity demanded of CD’s per month rises to eight.
Types
When the income of a person increases, his demand for goods also changes depending upon whether the good is a normal good or an inferior good. For normal goods, the value of elasticity is greater than zero but less than one. Goods with an income elasticity of less than 1 are called inferior goods.
Formula
The numerical value of cross elasticity depends on whether the two goods in question are substitutes, complements or unrelated.
Definition
A demand is perfectly elastic when a small increase in the price of a good leads its demand to zero. Perfect elasticity implies that individual producer can sell all his products at a ruling price but cannot charge a higher price. If any producer tries to charge even one penny more, no one would buy his product.
Diagram
It shows that the demand curve DD / is a horizontal line which indicates that the quantity demanded is extremely (infinitely) response to price. Even a slight rise in price (say $4.02), drops the quantity demanded of a good to zero. The curve DD / is infinitely elastic.
Definition
When the quantity demanded of a good dose not change at all to whatever change in price, the demand is said to be perfectly inelastic or the elasticity of demand is zero (PED = 0).
Diagram
In diagram 6.2, a rise in price from OA to OC or fall in price from OC to OA causes no change (zero responsiveness) in the quantity demanded.
Definition
When the quantity demanded of a good changes by exactly the same percentage as price, the demand is said to be a unitary elasticity.
Diagram
In above diagram (6.3) DD / demand curve with unitary elasticity shows that as the price falls from OA to OC, the quantity demanded increases from OB to OD. On DD / demand curve, the percentage change in price brings about an exactly equal percentage in quantity at all points a, b.
Definition
If a one percent change in price causes greater than a one percent change in quantity demanded of a good, the demand is said to be elastic.
