When PED is less than one, demand is inelastic. The effect of price changes on total revenue PED may be important for businesses attempting to distinguish how to maximize revenue For example, if a business finds out its PED is very inelastic, it may want to raise its prices because it knows that it can sell its products for a higher price without losing many sales.
Conversely, if a business finds that its PED is very elastic, it may wish to lower its prices. This would allow the business to dramatically increase the number of units sold without losing much revenue per unit. There are two notable cases of PED. The first is when demand is perfectly elastic. Perfectly elastic demand is represented graphically as a horizontal line.
In this case, any increase in price will lead to zero units demanded. Perfectly Elastic Demand : Perfectly elastic demand is represented graphically by a horizontal line. In this case the PED value is the same at every point of the demand curve.
The second is perfectly inelastic demand. Perfectly inelastic demand is graphed as a vertical line and indicates a price elasticity of zero at every point of the curve.
This means that the same quantity will be demanded regardless of the price. Perfectly Inelastic Demand : Perfectly inelastic demand is graphed as a vertical line. The PED value is the same at every point of the demand curve. Since PED is measured based on percent changes in price, the nominal price and quantity mean that demand curves have different elasticities at different points along the curve.
Elasticity along a straight line demand curve varies from zero at the quantity axis to infinity at the price axis. Below the midpoint of a straight line demand curve, elasticity is less than one and the firm wants to raise price to increase total revenue.
Above the midpoint, elasticity is greater than one and the firm wants to lower price to increase total revenue. At the midpoint, E1, elasticity is equal to one, or unit elastic.
Elasticity and the Demand Curve : The price elasticity of demand for a good has different values at different points on the demand curve. The numerical value of relatively inelastic demand always comes out as less than 1 and the demand curve is rapidly sloping for such type of demand. Recommended Read: Microeconomics vs Macroeconomics.
When the proportionate change in the quantity demanded for a product is equal to the proportionate change in the price of the commodity, it is said to be unitary elastic demand.
The numerical value for unitary elastic demand is equal to 1. The demand curve for unitary elastic demand is represented as a rectangular hyperbola. 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. To explain the extent of the effect of the economic variables on the quantity demanded, we have 5 other types of elasticity of demand which are perfectly elastic, perfectly inelastic, relatively elastic, relatively inelastic, and unitary elastic.

Also, read our blog on 4 types of Elasticity in economics Elasticity of Demand Elasticity of Demand, or Demand Elasticity, is the measure of change in quantity demanded of a product in response to a change in any of the market variables, like price, income etc.
The demand for a commodity is affected by different economic variables: Price of the commodity Price of related commodities Income level of consumers We will read about these in detail, later in the blog. Let us look at them in detail and their examples.

Part Of. Introduction to Microeconomics. Microeconomics vs. If you're starting to wonder if the concept of slope fits into this calculation, read the following Clear It Up box. It is a common mistake to confuse the slope of either the supply or demand curve with its elasticity.
The price elasticity, however, changes along the curve. Elasticity between points A and B was 0. Elasticity is the percentage change, which is a different calculation from the slope and has a different meaning. When we are at the upper end of a demand curve, where price is high and the quantity demanded is low, a small change in the quantity demanded, even in, say, one unit, is pretty big in percentage terms.
A change in price of, say, a dollar, is going to be much less important in percentage terms than it would have been at the bottom of the demand curve. Likewise, at the bottom of the demand curve, that one unit change when the quantity demanded is high will be small as a percentage. So, at one end of the demand curve, where we have a large percentage change in quantity demanded over a small percentage change in price, the elasticity value would be high, or demand would be relatively elastic.
Even with the same change in the price and the same change in the quantity demanded, at the other end of the demand curve the quantity is much higher, and the price is much lower, so the percentage change in quantity demanded is smaller and the percentage change in price is much higher.
That means at the bottom of the curve we'd have a small numerator over a large denominator, so the elasticity measure would be much lower, or inelastic.
Price elasticity measures the responsiveness of the quantity demanded or supplied of a good to a change in its price. It is computed as the percentage change in quantity demanded or supplied divided by the percentage change in price.
Elasticity can be described as elastic or very responsive , unit elastic, or inelastic not very responsive. Elastic demand or supply curves indicate that quantity demanded or supplied respond to price changes in a greater than proportional manner.
An inelastic demand or supply curve is one where a given percentage change in price will cause a smaller percentage change in quantity demanded or supplied. A unitary elasticity means that a given percentage change in price leads to an equal percentage change in quantity demanded or supplied. The demand curve is inelastic in this area; that is, its elasticity value is less than one. The demand curve is elastic in this interval.
The supply curve is elastic in this area; that is, its elasticity value is greater than one. The supply curve is inelastic in this region of the supply curve.
