Elasticity is also defined in economics as the measurement of percentage change of one economics value in response to change in the other. Elasticity is a central concept in economics and has many applications.
Basic demand and supply models explain that different variables like price, demand, income are generally related. So, what elasticity does is that it can provide crucial information about the strength and weakness of such relationships. Based on the value of elasticity variables are categorized as elastic or inelastic. An elastic variable with an absolute elasticity value greater than 1 is one that responds more than proportionally to changes in other variables. In contrast, an inelastic variable with an absolute elasticity value less than 1 is one which changes less than proportionally in response to changes in other variables.
To better understand the working we should move to the next section of the blog. Recommended blog: What is Managerial Economics? Definition, Types, Nature, Principles, and Scope. When the value of elasticity is greater than 1. On the other hand, when the value of elasticity is less than 1. We also call it inelastic.
Inelastic means that the buying habit of consumers remains more or less the same, irrespective of the change in prices. There is one more situation that is just theoretical i.
This happens when the value of elasticity is zero. This would mean that the demand for the perfectly inelastic good will remain the same even if the prices are changed drastically. The explanation itself might have cleared that there are no real-world examples of perfectly inelastic goods.
Even if there was a good, it might have been the costliest as the producers and suppliers would be free to charge anything considering the demand. Elasticity is a financial idea used to gauge the adjustment in the total amount demanded for a good or service according to value developments of that good or service.
An item is viewed as elastic if the amount of interest in the item changes radically when its cost increments or diminishes. On the other hand, an item is viewed as inelastic if the amount of interest of the item changes almost no when its cost vacillates. Taking the examples of both kinds of goods. An example of a highly inelastic good is insulin. On the other hand are highly elastic products. There can be various examples of goods that fall in this category. For example, the demand for refrigerators go high during festive seasons as the prices are slashed and people wait for it.
As mentioned above in the blog, there are mainly two types of elasticity- Elasticity of Demand and Elasticity of Supply. Elasticity of demand is an economic measure of the sensitivity of demand relative to a change in another variable.
If the price of one soda rises, consumers can opt to buy the cheaper substitute. When close substitutes are available, the quantity demanded is highly sensitive to changes in the price level and vice versa. The demand elasticity of goods with close substitutes is measured by dividing the percent change of the quantity demanded of one product by the percent change in the price of a substitute product.
This formula is also known as the cross elasticity of demand. Lastly, the level of consumer income plays a role in the demand elasticity of goods and services. The income elasticity of demand is used to measure the sensitivity of a change in the quantity demanded relative to a change in consumers' incomes.
Different types of goods are affected by income levels. For example, inferior goods, such as generic products, have a negative income elasticity of demand because the quantity demanded for generic products tends to fall as consumers' incomes increase.

Basic demand and supply analysis explains that economic variables, such as price, income and demand, are causally related. Elasticity can provide important information about the strength or weakness of such relationships.
Elasticity refers to the responsiveness of one economic variable, such as quantity demanded, to a change in another variable, such as price. There are four types of elasticity, each one measuring the relationship between two significant economic variables. They are:. Price elasticity of demand PED , which measures the responsiveness of quantity demanded to a change in price.
PED can be mmeasured over a price range, called arc elasticity, or at one point, called point elasticity. The cross-price elasticity of demand , the percentage change in demand of one good divided by the percentage change in the price of a related good, measures how much changes in the price of related goods affect consumer purchases. The advertising elasticity of demand, the percentage change in demand divided by the percentage change in advertising expenditures, measures how much changes in advertising expenditures affect consumer purchases.
How do we measure how much producers respond to a price change? We do this in the same basic way we measure whether consumers respond to a price change: we calculate the price elasticity of supply.
The price elasticity of supply is the percentage change in the quantity supplied divided by the percentage change in price. The price elasticity of supply depends primarily on the length of time producers have to vary their output in response to changes in price.
Chapter Review. Third, the longer the period under consideration, the more elastic the demand.
