# Price demand relationship and the elasticity of

Elastic Demand and Total Revenue. Elastic Demand: Elasticity > 1. Percentage change in quantity is greater than percentage change in price. Raise Price. Both demand and supply curves show the relationship between price and the number of units demanded or supplied. Price elasticity is the ratio between the. Price elasticity of demand is a measure of the change in the quantity demanded or purchased of a product in relation to its price change.

## Price elasticity of demand and price elasticity of supply

For inelastic goods, because of the inverse nature of the relationship between price and quantity demanded i. But in determining whether to increase or decrease prices, a firm needs to know what the net effect will be.

Elasticity provides the answer: The percentage change in total revenue is approximately equal to the percentage change in quantity demanded plus the percentage change in price. One change will be positive, the other negative. As a result, the relationship between PED and total revenue can be described for any good: Goods necessary to survival can be classified here; a rational person will be willing to pay anything for a good if the alternative is death. For example, a person in the desert weak and dying of thirst would easily give all the money in his wallet, no matter how much, for a bottle of water if he would otherwise die.

His demand is not contingent on the price. Hence, when the price is raised, the total revenue increases, and vice versa. Hence, when the price is raised, the total revenue falls, and vice versa. Hence, when the price is raised, the total revenue falls to zero. This situation is typical for goods that have their value defined by law such as fiat currency ; if a five-dollar bill were sold for anything more than five dollars, nobody would buy it, so demand is zero. Hence, as the accompanying diagram shows, total revenue is maximized at the combination of price and quantity demanded where the elasticity of demand is unitary.

You don't have any alternative, so you pay the higher price, buy the needed quantity of gasoline and go to your job.

That's called price inelasticity. What Is Price Elasticity? Price elasticity measures the changes in demand for a product in reaction to changes in the price for that product. It's a ratio of percentages, and the formula is as follows: When the ratio is less than one, the demand for a product does not change substantially with changes in price.

In this case, a company could increase its prices and not suffer a significant decline in sales volume.

## Price elasticity of demand

The elasticity is calculated as follows: The price for oatmeal goes up, and consumers buy less of the product. They may start buying other cereal products, or they might switch to the grocery store's generic brand of oatmeal. Factors That Affect Elasticity The factors that affect the price elasticity of any product include: As in the case of rising prices for oatmeal, consumers can shift their purchases to similar products if they are readily available.

Coca-Cola and Pepsi are products that can be easily substituted for each other when prices change.
