Demand that is relatively elastic suggests that a change in the price of a good or service will have an effect on the quantity required of that good or service. A product or service is typically said to have significant price elasticity when there are several replacements available.
Example: You might see salt and a variety of salt alternatives when you browse the aisle at the grocery store. Would you be willing to pay an extra $2 for a bag of salt if there were salt replacements instead if the price of salt increased by $2 per bag tomorrow? Most people would switch from preferring salt to one that contains sugar substitutes, which would lower their demand for pure salt. Since most economists concur, salt is viewed as a good with a high degree of elasticity.

Relatively Inelastic Demand
Petrol is one product whose price is thought to be relatively inelastic. Both consumers and businesses need gas to prosper in our market. Despite the march toward alternative fuels, there are still a lot of individuals who depend on petrol for everyday needs and are unable or unlikely to switch to alternative fuels as a workable replacement.
Would you still report to work tomorrow if petrol prices rose by 30%? Most individuals will pay more because they have to. There are, of course, exceptions. Prices rose to a national average peak of almost $4.10 per petrol during the oil and gas bubble in 2008, and customers adjusted their behaviour by requesting less gas. Some analysts believed that the sharp recession that occurred in late 2008 and 2009 was caused by this shift in demand.An excellent example of a relatively inelastic demand is found in luxury items like TVs and designer labels.
Example: A well-known slipper company sells 2,000 pairs of their flagship model, which retails for $100, each month. The company chooses to cut the cost of the slipper by 20%, from $100 to $80. At the current price, which represents a 25% increase, it starts selling 2,500 pairs per month. Given that the 25 % rise in demand exceeds the 20 percent variation in cost, slippers are considered to be relatively elastic.

Types of Elasticity of Demand
Elasticity of demand is classified into three types based on the many elements that influence the quantity desired for a product: price elasticity of demand (PED), cross elasticity of demand (XED), and income elasticity of demand (IED) (YED).
1)Price Elasticity of Demand (PED)
The quantity requested for a product is affected by any change in the price of a commodity, whether it be a drop or an increase. For example, as the price of ceiling fans rises, the quantity requested decreases.
The Price Elasticity of Demand is a measure of the responsiveness of quantity sought when prices vary (PED).
The mathematical formula for calculating Price Elasticity of Demand is as follows:
2). Income Elasticity of Demand (YED)
Consumer income levels have a significant impact on the amount requested for a product. This may be seen in the contrast between commodities sold in rural marketplaces and those sold in urban markets.
The Income Elasticity of Demand, commonly known as YED, refers to the sensitivity of the quantity requested for a certain commodity to changes in real income (the income generated by a person after accounting for inflation) of the consumers who buy this good, while all other variables remain constant.
The formula for calculating the Income Elasticity of Demand is as follows:
The formula's output may be used to assess if a product is a need or a luxury item.
3. Cross Elasticity of Demand (XED)
In an oligopolistic market, numerous companies compete. Thus, the amount desired for a commodity is affected not only by its own price, but also by the prices of other items.
Cross Elasticity of Demand (XED) is an economic term that assesses the sensitivity of quantity requested of one good (X) when the price of another item (Y) changes, and is also known as Cross-Price Elasticity of Demand.
The formula for calculating the Cross Elasticity of Demand is as follows:
The result for a substitute good would always be positive since anytime the price of an item rises, so does the demand for its alternative. In the case of a complementary good, however, the outcome will be negative.
Relatively Elastic Demand Example
The majority of necessities tend to be very inelastic.
Example : A youtube business with 50,000 subscribers offers a service for $100 a year. The corporation increases the subscription service's cost by 30%, from $100 per year to $130. The company now has 52,000 users, a 4 % increase after the price rise. The service is comparatively inelastic because the price increased by 30% while the demand increased by only 4%.
Economists attempt to quantify the degree to which demand is sensitive to changes in price for a particular good using the concept of price elasticity of demand. This assessment can be helpful in predicting consumer behaviour as well as big occurrences like an economic recession or recovery. Every day, as customers, we make choices that economists track. We may consume less of a good or none at all if its price rises and we can survive without it, there are many replacements, or both. Despite price hikes, we will continue to demand large amounts of water, medicine, and gasoline as needed.
