From a pricing formulation perspective, elastic demand is of great concern. Price elasticity is particularly common when the products of competing companies are not well differentiated, or where substitute products are readily accessible. The income elasticity of demand is defined as the measure of the percentage change of the quantity demanded of a good in reference to changes in the consumer’s income. Calculating the income elasticity of demand allows economists to identify normal and inferior goods, as well as how responsive quantity demanded is to changes in income. The law of demand states that an increase in price reduces the quantity demanded, and it is why demand curves are downwards sloping unless the good is a Giffen good. For example, if the price of Sainsbury’s Caledonian mineral water increases, you would probably switch to other varieties of mineral water.

Being in an elastic market will benefit the companies because if they lower their price slightly, there is a large boost in demand. This is beneficial to the company as this allows them to achieve economies of scale.

Together, the two elasticities combine to determine what goods are produced at what prices. Elasticity is an important economic measure, particularly for the sellers of goods or services, because it indicates how much of a good or service buyers consume when the price changes. When a product is elastic, a change in price quickly results in a change in the quantity demanded.

What is Elastic Demand?

A product is said to be price inelastic if the preceding ratio is less than 1, and price elastic if the ratio is greater than 1. Revenue should be maximized when you can set the price to have an elasticity of exactly 1. On the contrary, if the aforementioned goods were complements, when the price of good B increases, the demand for good A should decrease.

One thing all these products have in common is that they lack good substitutes. Addicts are not dissuaded by higher prices, and only HP ink will work in HP printers (unless you disable HP cartridge protection). Perfectly elastic demand is when the demand for the product is entirely dependent on the price of the product. This means that if any producer increases his price by even a minimal amount, his demand will disappear. If demand is inelastic then increasing the price can lead to an increase in revenue.

Duration of Price Change

The measured value of elasticity is sometimes called the elasticity coefficient. When measured, the price elasticity of demand will have an elasticity coefficient greater than or equal to 0 and can be divided into five zones depending on the value of the coefficient. Clarity of time sensitivity is vital to understanding the price elasticity of demand and for comparing it with different products. Consumers may accept a seasonal price fluctuation rather than change their habits.

Perfectly Elastic Demand Conclusion

Examples of perfectly elastic products are luxury products such as jewels, gold, and high-end cars. A perfectly elastic demand curve will be a straight line (horizontal) on a graph, where the x-axis will be the quantity, and the y-axis will be the price of the product. The market demand for a product is directly tied to the price of the product. The formula for calculating income elasticity of demand is the percent change in quantity demanded divided by the percent change in income.

How to Use a Demand Curve Graph

Firms that are inelastic, on the other hand, have goods and services that are must-haves and enjoy the luxury of setting higher prices. When demand is elastic, it is more sensitive to the changes it is being measured against. Inelastic goods are less sensitive to the changes they are being measured against. At an elasticity of 0 consumption would not change at all, in spite of any price increases. The more easily a shopper can substitute one product for another, the more the price will fall.

A product is considered to be elastic if the quantity demand of the product changes more than proportionally when its price increases or decreases. Conversely, a product is considered to be inelastic if the quantity demand of the product changes very little when its price fluctuates. In business and economics, price elasticity refers to the degree to which individuals, consumers, or producers change their demand or the amount supplied in response to price or income changes. It is predominantly used to assess the change in consumer demand as a result of a change in a good or service’s price. The calculations for each type of elasticity are slightly different, but the intuition behind all elasticities is the same. In every case, elasticity measures the responsiveness of one factor—typically the quantity demanded or supplied of a good—relative to a percentage change in some other factor such as price or income.

Types of Price Elasticity of Demand

If a firm knows demand is price elastic, raising the price is likely to cause a significant fall in demand and a fall in revenue. The quantity demanded of a good or service depends on multiple factors, such as price, income, and preference. Whenever there is a change in these variables, it causes a change in the quantity demanded of the good or service. Elasticity is an economic concept used to measure the change in the aggregate quantity demanded of a good or service in relation to price movements of that good or service.
