Elasticity of Demand Types, Importance, Formula and Examples

5 types of price elasticity of demand

The quantity demanded is extremely responsive to price changes, moving from zero for prices close to P to infinite when prices reach P. Demand is described as elastic when the computed elasticity is greater than 1, indicating a high responsiveness to changes in price. Computed elasticities that are less than 1 indicate low responsiveness to price changes and are described as inelastic demand.

With price inelastic (as opposed to perfectly inelastic) demand, the demand curve itself is still downward sloping. The slope of a line is the change in the value of the variable on the vertical axis divided by the change in the value of the variable on the horizontal axis between two points. The slope of a demand curve, for example, is the ratio of the change in price to the change in quantity between two points on the curve. The price elasticity of demand is the ratio of the percentage change in quantity to the percentage change in price. As we will see, when computing elasticity at different points on a linear demand curve, the slope is constant—that is, it does not change—but the value for elasticity will change. Inelastic demand occurs when changes in price cause a disproportionately small change in quantity demanded.

If price changes by 10% the quantity demanded of the commodity change by more than 10% i.e. 25%. The elasticity of demand is an important concept when understanding the demand and supply mechanism in the economy. Understand what it is all about, the different types of elasticities and how it is measured. The elasticity would give you an understanding how the quantity demanded changes with respect to other factors affecting demand. If you own a business, you would be able to price your products correctly so that your demand stays up for maximum revenue.

We use the word elasticity to describe the property of responsiveness in economic variables. We also describe the responsiveness as (relatively) elastic or (relatively) inelastic. We can also describe elasticity as perfectly elastic or perfectly inelastic. As the price of Hulu Live rises, the demand for its competitor’s service rises.

If your product has a lot of competition that is pretty similar, raising prices will most likely drive consumers away. Conversely, if a slice of pizza you purchased every day for lunch went up by $0.50, would it affect your purchase? As long as you weren’t super attached to the pizza and had other options (more on this below), you probably would move to another lunch establishment.

What Is the Importance of Price Elasticity of Demand?

For example, you probably don’t even know how much that pack of Paper Mate pens costs, so when the price rises by 10% (just a few cents), you likely won’t notice. But, if the price decreases by 10% on that new car you want (hundreds or thousands of dollars), you’re sure to notice. Most businesses want to capture as much of the cash on the table as possible. To do this, you need to make your product as inelastic as possible, increasing demand, regardless of how expensive you make the product. Determine the equilibrium price and quantity using the demand and supply curve. One thing all these products have in common is that they lack good substitutes.

On the other hand, if the demand is only marginally impacted, the product is called ‘inelastic’. Usually, if income rises, the demand is expected to increase since customers can afford more products at increased income levels. Elastic demand means the demand changes in a large variation in response to a comparatively small variation in a price change.

How to determine the price elasticity of demand for your product

Consumers are unwilling to spend more and therefore go elsewhere instead. Some products/services are able to achieve a ‘geographical monopoly’, whereby consumers have little choice. For instance, we only need to look at football or baseball games as examples – customers can only buy food and drink available in the stadium. The consumer’s willingness to pay is much greater because there is no alternative, with an element of convenience. Elasticity refers to the ratio of the proportionate rate of change in one variable and the proportionate rate of change in another variable.

5 types of price elasticity of demand

The availability of close substitutes tends to make the demand for Fords more price elastic. The greater the absolute value of the price elasticity of demand, the greater the responsiveness of quantity demanded to a price change. The most important determinants of the price elasticity of demand for a good or service are the availability of substitutes, the importance of the item in household budgets, and time. The demand curve in Panel (c) has price elasticity of demand equal to −1.00 throughout its range; in Panel (d) the price elasticity of demand is equal to −0.50 throughout its range.

Types of Price Elasticity of Demand – Full Explanation

I just threw out a lot of words like “unit”, “elastic”, “coefficient”, “lazy”, etc. Economists like to use fancy words, so let’s break this down a bit with some examples of price elasticity of demand. But the demand curve varies greatly based on the product, particularly on how necessary the product is. A good with perfectly inelastic demand would have a PED of 0, where even huge changes in price would cause no change in demand.

Consider a person with diabetes who needs insulin to stay alive. If the price of insulin decreases, the patient can’t stock up and save it for the future. If the price of insulin increases, the patient will continue to purchase the same quantity needed to stay alive. Perfectly inelastic 5 types of price elasticity of demand demand means that quantity demanded remains the same when price increases or decreases. The problem in assessing the impact of a price change on total revenue of a good or service is that a change in price always changes the quantity demanded in the opposite direction.

What Are the Types of Price Elasticity?

When the price elasticity of a good is less than 1, it’s considered inelastic. That means a one-unit increase in price resulted in a less than one-unit decrease in demand. On the other hand, if the coefficient (the absolute value) is more than 1, the good is elastic. One of the pillars of pricing strategy and microeconomics is the theory of price elasticity of demand, or simply price elasticity. Below we discuss price elasticity and how to increase demand by making your offering more inelastic through marketing and product development.

5 types of price elasticity of demand

The price elasticity of demand for gasoline in the intermediate term of, say, three–nine months is generally estimated to be about −0.5. Since the absolute value of price elasticity is less than 1, it is price inelastic. We would expect, though, that the demand for a particular brand of gasoline will be much more price elastic than the demand for gasoline in general. Moving from point A to point B implies a reduction in price and an increase in the quantity demanded.

This measures the demand for a product based on the price of another product. For example, if the price of Coca-Cola rises, the demand for Pepsi is likely to increase. This price sensitivity can work in the other direction, e.g. if the price of burgers were to rise, the demand for burger buns would drop. Inelastic demand describes the scenario where fluctuations in price do not change the demand for a good.

  • The horizontal line shows that an infinite quantity will be demanded at a specific price.
  • If your PED equals 0, price changes do not affect your product’s demand.
  • As we can see from the chart above – demand hardly reacts to a change in price.
  • Consumers will have to travel far to get the same bread, which makes them less responsive to an increase in its price by the local grocery.
  • For any linear demand curve, demand will be price elastic in the upper half of the curve and price inelastic in its lower half.

Price elasticity gives you some useful information on how to best price your products and services. However, it’s important to note that a decrease in the quantity demanded does not automatically mean that revenue decreases. The additional profit margin could make up for the slight decrease in purchases. The elasticity of demand for the commodity is inelastic because the co-efficient is less than one. The change in demand shows a negative sign, which can be ignored. 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.
