On the basis of the amount of fluctuation shown in the quantity demanded of a good, it is termed as ‘elastic’, ‘inelastic’, and ‘unitary’. The demand for a product can be elastic, inelastic, or unitary, depending on the rate of change in the demand with respect to the change in the price of a product. Companies that operate in fiercely competitive industries provide goods or services that are elastic. This is because these companies tend to be price-takers, meaning they typically must accept prevailing prices.

At the time of taking decision to devalue or revalue the currency, the government should carefully study the nature of the elasticity of demand and supply of its exports as well as for its imports. The study of elasticity of demand is not only important for the price policies of the producers, it is equally important in determining the factor rewards in a free enterprise economy. If, however, the demand curve is non-linear, then draw a tangent at the given point, extending it to intercept both the axes as indicated in fig.

Significance in Economic Decision-Making

In general, elasticity refers to the responsiveness of one variable to changes in another. In economics, this most frequently refers to demand elasticity, or how demand fluctuates based on changes in other factors, such as price, income, and more. When a good or service is inelastic, demand fluctuates very little regardless of changes in other factors.

Essential goods, like gasoline, often exhibit inelastic demand, as consumers continue to purchase them despite price fluctuations. Elasticity of demand is a fundamental concept in economics that plays a pivotal role in understanding how changes in price impact the quantity demanded elasticity of demand types for a particular good or service. The demand curve for a perfectly inelastic demand is a vertical line i.e. the slope of the curve is zero.

Importance of the Concept of Elasticity of Demand:

As you might expect, the greater the amount of the tax increase, the fewer cigarettes are bought and consumed. While the taxes are somewhat of a deterrent, demand doesn’t decrease as much as the price increase, though. We can say, then, that the demand for cigarettes is relatively inelastic.

Example of Unitary Elastic Demand

This issue reaches beyond governments and taxes; every firm faces a similar challenge. Every time a firm considers raising the price that it charges, it needs to know how much a price increase will reduce the quantity of its product that is demanded. Conversely, when a firm puts its products on sale, it wants assurance that the lower price will lead to a significantly higher quantity demanded. In Figure, DD is the demand curve that slopes steeply with a fall in price. However, the rise in demand QQ1 is less than the fall in price PP1. The cross elasticity of demand is affected by the nature of the two goods, i.e., whether they are close substitutes, complements or unrelated to one another.

Factors influencing demand elasticity in energy

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. The demand for a product can be elastic or inelastic, depending on the rate of change in the demand with respect to change in price of a product. Let as first take one extreme case of elasticity of demand, viz., when it is infinite or perfect.

• Elastic products are more price-sensitive, and businesses that deal with such products must carefully monitor pricing strategies to avoid sharp declines in demand.
• When a product is elastic, a change in price quickly results in a change in the quantity demanded.
• Further, Elasticity of Demand refers to the responsiveness of sensitiveness of demand to a change in price.
• Elasticity of demand measures the change in demand when the price or other factors change.

Relatively Elastic Demand:

• Through the analysis of elasticity, firms can take rational pricing decisions with optimum revenue maximization and gain some pre-estimation about shifts in the market that will be developing.
• If the price of insulin increases, the patient will continue to purchase the same quantity needed to stay alive.
• The concept of elasticity of demand is of great significance in economic analysis.
• If the percentage change in the quantity demanded is exactly in the same percentage change in price it is known as unit elasticity.

Elasticity of demand is infinity when even a negligible fall in the price of the commodity leads to an infinite extension in the demand for it. 10.1 the horizontal straight line DD’ shows infinite elasticity of demand. Demand extends or contracts respectively with a fall or rise in price. This quality of demand by virtue of which it changes (increases or decreases) when price changes (decreases or increases) is called Elasticity of Demand. The elasticity of demand stands as a cornerstone in economic analysis, influencing a myriad of decisions in both the public and private sectors. Its implications extend to taxation policies, investment decisions, supply chain management, and even the rapidly evolving landscape of online markets.

In Income elasticity of demand, the responsiveness of demand to change in income. The elasticity of demand is the proportionate change of amount purchased in response to a small change in price, divided by the proportionate change in price. Higher tax leads to a big increase in price and small fall in demand. When the proportionate change in demand exceeds the proportionate change in the good's price, the demand is said to be relatively elastic.

However, in the long run, as consumers explore alternative modes of transportation or fuel-efficient vehicles, demand becomes more elastic. Goods that constitute a significant portion of consumers’ income tend to have more elastic demand. Small price changes have a larger impact on the budget, leading to a more significant response. Elastic demand indicates that quantity demanded is highly responsive to changes in price. Consumers tend to reduce their quantity demanded significantly when prices rise and increase it substantially when prices fall. 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.

When the price of a good or service reaches the point of elasticity, sellers and buyers quickly adjust their demand for that good or service. Cross elasticity of demand can be defined as a measure of a proportionate change in the demand for goods as a result of change in the price of related goods. This measures how much the quantity demanded changes when the price changes.

The concept of price elasticity of demand has important practical applications in managerial decision-making. Here, the concept of elasticity of demand becomes vital in answering such questions. In the above case the fall in price is 20% whereas the instance in demand is 25%. If we use the percentage method then it is a case of elastic demand.

The price elasticity of demand for milk is 0.2, which is less than one. Therefore, in such a case, the demand for milk is relatively inelastic. In Figure, DD is the demand curve that slopes gradually down with a fall in price. However, the rise in demand QQ1 is greater than the fall in price PP1.
