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. The demand for a good or service depends on multiple factors such as price, income, and preference. Whenever there is a change in any of these variables it causes a change in the quantity demanded of the good or service. Price Elasticity of Demand or PED measures the responsiveness of quantity demanded to a change in price.

Key Takeaways Elasticity of demand is a measure of the responsiveness of a change in demand given a change in a variety of other factors including the product's price. Price elasticity of demand is perhaps the most well-recognized, measuring how demand changes for an item if its price changes, with some goods' demand more sensitive to price than others.
Income elasticity of demand refers to the sensitivity of the quantity demanded for a certain good to a change in real income of consumers who buy this good.
Cross elasticity of demand is an economic concept that measures the responsiveness in the quantity demanded of one good when the price for another good changes. Compare Accounts. The offers that appear in this table are from partnerships from which Investopedia receives compensation.
As people have more income, they might be able to afford better cars that are more reliable, that break down less, and then they would have to go to the car mechanic less. And so that situation, where our demand would actually go down when our income goes up, or our percent change will become negative when we have a positive percent change income, that would be, that is known as an inferior good. Inferior good. There's two big things to take away.
One, you don't just have to think about price elasticity of supply or demand, there are other types of elasticities. But just to hit the point home on income elasticity, let's look at a few examples. In this situation, what type of good would fast food be? Pause this video and think about it. Well, their income is increasing but their demand is decreasing.
That's the situation we just talked about. This is an inferior good. And for kicks, what is the income elasticity of demand right over here, calculate that. Just remember, our income elasticity of demand is just going to be our percent change in quantity demanded divided by our percent change, instead of price, we're going to say in income. I'll just write percent change of income, which is going to be what?
Well, we know our percent change in income. Sometimes laws are proposed that seek to increase the quantity of savings by offering tax breaks so that the return on savings is higher. Such a policy will increase the quantity if the supply curve for financial capital is elastic, because then a given percentage increase in the return to savings will cause a higher percentage increase in the quantity of savings. However, if the supply curve for financial capital is highly inelastic, then a percentage increase in the return to savings will cause only a small increase in the quantity of savings.
The evidence on the supply curve of financial capital is controversial but, at least in the short run, the elasticity of savings with respect to the interest rate appears fairly inelastic. The elasticity concept does not even need to relate to a typical supply or demand curve at all.
For example, imagine that you are studying whether the Internal Revenue Service should spend more money on auditing tax returns. The question can be framed in terms of the elasticity of tax collections with respect to spending on tax enforcement; that is, what is the percentage change in tax collections derived from a percentage change in spending on tax enforcement?
With all of the elasticity concepts that have just been described, some of which are listed in Table 1, the possibility of confusion arises. Practice until you feel comfortable doing the questions.
