By definition, if the elasticities of demand at each price are equal on two different demand curves, then the two demand curves are said to be iso-elastic.
What is inelastic demand?
" Inelastic demand " is a term that economists use to refer to a situation where demand for an item remains the same, no matter how far its price rises or falls. A product or service is said to have elastic demand when the change in quantity demanded is large when there is a change in price.
Which two demand curves are iso-elastic?
Therefore, at any particular price OP, the values of e on the demand curves (lines) AB and AC (at the points F and G, respectively) have been obtained to be identical. Therefore, here the two demand curves AB and AC are iso-elastic. Type: 3. Parallel Demand Curves:
What is isoelastic utility?

Four types of elasticity are demand elasticity, income elasticity, cross elasticity, and price elasticity.
What is price elasticity example?
Example of Price Elasticity of Demand As a rule of thumb, if the quantity of a product demanded or purchased changes more than the price changes, then the product is considered to be elastic (for example, the price goes up by 5%, but the demand falls by 10%).
What is elastic demand examples?
Elastic Demand These are items that are purchased infrequently, like a washing machine or an automobile, and can be postponed if price rises. For example, automobile rebates have been very successful in increasing automobile sales by reducing price. Close substitutes for a product affect the elasticity of demand.
How do you interpret a demand curve?
If any determinants of demand other than the price change, the demand curve shifts. If demand increases, the entire curve will move to the right. That means larger quantities will be demanded at every price. If the entire curve shifts to the left, it means total demand has dropped for all price levels.
What do you mean by demand curve?

What is straight line demand?from askinglot.com
Straight line (linear) demand curve The price elasticity of demand can also be measured at any point on the demand curve. If the demand curve is linear (straight line), it has a unitary elasticity at the midpoint. The total revenue is maximum at this point. The value of PED falls as price falls.
What does constant unit elasticity mean?from khanacademy.org
Because constant unit elasticity means if price goes down by 1, quantity increase by 1.
What is elasticity in math?from khanacademy.org
Elasticity is a mathematical concept related to various factors such as necessity, substitutes, price, income, habits, and durability, rather than the notion of it being an intrinsic value specific to goods. Certain situations may make necessities elastic and vice versa.
Why is the elasticity always 1?from khanacademy.org
Because that is the mathematical consequence of assuming "unit elasticity". Saying "the elasticity is always 1" is just another way of saying "The curve is shaped like this"
Is income elasticity inferior to goods?from khanacademy.org
in case of income elasticity and specifically in inferior goods we don't so that we understand they are inferior goods.
What is inelastic demand?
Inelastic demand is when a buyer’s demand for a product does not change as much as its change in price. When price increases by 20% and demand decreases by only 1%, demand is said to be inelastic. This situation typically occurs with everyday household products and services. Products and Services A product is a tangible item ...
What are the two types of inelastic demand curves?
Demand Curve. There are two types of inelastic demand curves: 1. Perfectly inelastic demand. 2. Inelastic demand. An example of the two types of curves are shown below: Note: Perfectly inelastic demand is when a change in prices does not change the quantity of demand at all.

How to label an indifference curve?from microeconomicsnotes.com
By drawing a diagonal line from the origin, it is possible to label indifference curves, i.e., to label to each indifference curve to show how far it is from the origin, measured along the diagonal line, so long as preferences are monotonic. Almost any type ‘reasonable’ preference (consistent choice) can be represented by a utility function.
What is the equation for a quasi-linear preference?from microeconomicsnotes.com
In this case all the indifference curves are just vertically shifted versions of the origin indifference curve (the first one). The equation of an indifference curve in this case is x 2 = a – v (x 1) where a is a constant.

Definition and Examples of Elastic Demand
Whether demand for an item or service is elastic or inelastic is measured by its percent of change in demand divided by its percent of change in price, if all other factors remain the same. If an item's change in price changes in proportion to its change in demand, it is neither elastic nor inelastic.
How Does Elastic Demand Work?
The law of demand guides the relationship between price and the quantity demanded. It states that the quantity purchased has an inverse relationship with price. When prices rise, people buy less. The elasticity of demand tells you how much the amount bought decreases when the price increases.
Elastic Demand vs. Inelastic Demand
The opposite of elastic demand is inelastic demand. Demand changes more than price when it is elastic, and price changes more than demand when it is inelastic. In other words, an item has an inelastic demand when consumers are willing to tolerate greater changes in price before they alter their behavior.
What is the definition of iso-elastic demand curve?
By definition, if the elasticities of demand at each price are equal on two different demand curves, then the two demand curves are said to be iso-elastic.
What is the demand curve for each point on a horizontal straight line?
Of course, at each point on a horizontal straight line demand curve, e = ∞ (Fig. 2.4).
What happens if two straight line demand curves intersect?
If any two straight line demand curves intersect each other, then, at any particular price of the good concerned, the steeper line would have a lower e and the flatter line would have a higher e. The point is established with the help of Fig. 2.11 where, at the price p = OP, the straight line demand curves AB and CD have intersected at the point F. Of the two demand lines, AB is the steeper line and CD is the flatter line.
Is a demand curve negatively sloped?
That is why, from the point of view of elasticity measurement ,it shall be assumed that the demand curves are negatively sloped straight lines.
Is the value of e at any point on a curvilinear demand curve the same?
It is evident that the value of e at any (p, q) point on a curvilinear demand curve and the value of e at the same (p, q) point on a straight line demand curve—which is a tangent to the former demand curve at the said point—are identical.
Is the demand curve AB and AC iso elastic?
Therefore, here the two demand curves AB and AC are iso-elastic.
Is a parallel straight line demand curve isoelastic?
Therefore, the parallel straight line demand curves are not iso-elastic. At any particular price, of the two parallel straight line demand curves, the one nearer the origin (here AB) would have a higher e than the other (here CD).
