Price elasticity of demand
In economics and business studies, the price elasticity of demand (PED) is an elasticity that measures the nature and degree of the relationship between changes in quantity demanded of a good and changes in its price.
Introduction
When the price of a good falls, the quantity consumers demand of the good typically rises; if it costs less, consumers buy more. Price elasticity of demand measures the responsiveness of a change in quantity demanded for a good or service to a change in price.
Mathematically, the PED is the ratio of the relative (or percent) change in quantity demanded to the relative change in price. For most goods this ratio is negative, but in practice the elasticity is represented as a positive

It may be possible that quantity demanded for a good rises as its price rises, even under conventional economic assumptions of consumer rationality. Two such classes of goods are known as Giffen goods or Veblen goods. Another case is the price inflation during an economic bubble. Consumer perception plays an important role in explaining the demand for products in these categories. A starving musician who offers lessons at a bargain basement rate of $5.00 per hour will continue to starve, but if the musician were to raise the price to $35.00 per hour, consumers may perceive the musician's lessons ability to charge higher prices as an indication of higher quality, thus increasing the quantity of lessons demanded.
Various research methods are used to calculate price elasticity:
Test markets
Analysis of historical sales data
Conjoint analysis
Mathematical definition
The formula used to calculate the coefficient of price elasticity of demand for a given product is
This simple formula has a problem, however. It yields different values for Ed depending on whether Qd and Pd are the original or final values for quantity and price. This formula is usually valid either way as long as you are consistent and choose only original values or only final values.

The price elasticity of demand measures the sensitivity of the quantity demanded to price. The price elasticity of demand is the percentage change in quantity demanded brought by a 1 percent change in price. The value of price elasticity of demand for a normal good must always be negative, reflecting the fact that demand curves slope downward because of the inverse relationship of price and quantity.
Elasticity of demand is the relationship between the demands for a product with respect to its price. Generally, when the demand for a product is high, the price of the product decreases. When demand decreases, prices tend to climb. Products that exhibit the characteristics of elasticity of demand are usually cars, appliances and other luxury items. Items such as clothing, medicine and food are considered to be necessities. Essential items usually possess inelasticity of demand. When this occurs prices do not change significantly.
Elastic demand or “elasticity means the extent to which the quantity demanded changes when there’s a change in the price of a good” (Thinkwell, 2013). A product is considered elastic when the change in price increases the percentage change in quantity demanded. When
Price elasticity that relates to demand is determined by many factors. Price elasticity is measured by the change in price and the response from consumer demand. The demand of a good or service will vary the price in the item. The most important factor to determine the price elasticity of demand is necessity. If a good is a necessity, the demand will seldom change and the price is able to be adjusted. The demand is the most important due to the freedom it provides for price adjustment and inventory control. With necessity comes an inelastic price. Other factors such as the
a) Elasticity of demand are circumstance at which a good or service varies according to prices. These circumstances measures consumers reaction and how they respond to the changes in price by changing the quantity demanded. (PE-of-D = (% Change in Quantity Demanded/% Change in Price)) – When the price for a number of units decreases from positive units pre-dollars to negative units per-dollars, the quantity of units sold increases.
It shows how the demand for a product increase or decreases in price set. In Microeconomics this theory is called as Price elasticity of demand. Price elasticity of demand measures the change in quantity demanded or purchased of a product in relation to its price change (investinganswers.web). This Economical tool shows the response of how consumers react to price change. There are two types of defining the consumer attitude on Prices.
Elasticity of demand is measured as the percentage change in quantity demand divided by the percentage change in price .
Because the paint is at 2.56, this is considered to be elastic demand. This means that the demand for the good changes at a faster rate than the price change of the good. Sales fall off steeply when the price increases, but they jump sharply when the price declines.
Elasticity is a measure of the responsiveness of demand to changes in the price of a good or service. In the case of Steam Scot, when the price rises from 4 to 5, demand falls from 60,000 to 40,000 units. The original equilibrium market price of 4 pounds resulted in demand of 60,000 units and this generated revenue of 240,000 pounds. When the prices increased to 5 pounds the resulting demand is 40,000 units, and this generates total revenue of 200,000 pounds. When market price changes from 4 pounds to 5 pounds 40,000 pounds of revenue are lost in this indicates an elastic price elasticity of demand.
Elasticity of demand helps the sales manager in fixing the price of his product, deciding the sales, pricing policies and optimal price for their products. The evaluation of this measure is a useful tool for firms in making decisions about pricing and production which will determine the total
Elasticity of demand represented as “Ed” is defined as a “measure of the response of a consumer to a change in price on the quantity demanded of a good” (McConnell, 2012). Determinants for elasticity of demand would include the substitutability of a good, proportion of a consumer 's income spent on a good, the nature of the necessity of a good and the time a purchase is under consideration by the consumer. Furthermore, elasticity of demand is calculated with this formula:
When the price of a good rises the quality demanded falls, if we think about how much does it falls. To figure out by how much it falls we must calculate the price elasticity of demand which is calculate by how responsive demand is to rise in price. Also, the price elasticity of supply measures the responsiveness of quantity supplied to a change in price.
If the demand for the good or services of the company is elastic then the change in quantity demanded would be greater than a change in price. Let’s say the 10 percent decrease in price will cause increase in demand for 20 percent. The effect of this changes is that customers buying more products of this company. They are buying it for lower price but the price decrease outweigh by increasing quantity of the products or services. In this case the company benefits from these changes by raising profits. On the other hand, if company would raise the prices for the product the quantity will decrease so does the profit.
Recall that the elasticity of demand, which measures the responsiveness of demand to price, is given by
