Define and Explain the Concept

First, a quick review of Price Elasticity of Demand from lecture on 02/19/09. The definition, of Price Elasticity of Demand (PED) is: Price Elasticity of Demand = Percentage Change in Quantity Demanded = %ΔQD Percentage Change in Price

Price elasticity of demand is a Theory of the relationship between a change in the quantity demanded of a

The elasticity of demand measures the buyer’s reaction to price as its changing. “Economists measure the degree to which demand is price elastic or inelastic with the coefficient E d, defined as E d = percentage change in quantity demanded of product X/ percentage change in price of product X” (McConnell, C. 2011). Therefore, Ed=∆Qd/∆Pd. When elasticity of demand is measured less than one, demand is considered to be inelastic. The coefficient in an inelastic range is less than one. When this takes place the percentage change in price is more than the percentage change in quantity. It can be said that when inelastic demand is present that quantity becomes less effected by price changing.

For example, if the price of spaghetti sauce increases then the demand for the spaghetti noodles will decrease. If the price of spaghetti sauce decreases then the demand of spaghetti noodles will increase. Therefore, when the output of the cross price elasticity formula results in a negative coefficient means that the products are complementary goods.

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

Elasticity of demand is measured as the percentage change in quantity demand divided by the percentage change in price .

When the elasticity of demand is elastic, the change in quantity will be greater that the change in price. Hence, the total revenue will reduce with increasing prices and increase as prices decrease. However, if the business offers goods or services with inelastic price elasticity of demand, then the change in quantity demanded will be smaller than the change in price. Consequently, the total revenue, which is a product of the two will increase when

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: When a consumer is in greater need of resources, there is a smaller chance for price change. However, when goods and services are in less demand as a necessity, price change will not affect the economy as much. Elasticity is based on the change of supply and demand of goods and services that a society is in need of. (Investopedia)

Availability of Substitutes: This is the most important factor of what determines the price of elasticity of demand. Goods or services that have close similar substitutes will typically have more elastic demands associated with them (Jerelin, n.d.).

Market supply and demand determine the price therefore the price is elastic because the supply

Price elasticity of demand is an economic measure that is used to measure the degree of responsiveness of the quantity demanded of a good to change in its price, when all other influences on buyers remain the same.

When price elasticity of demand is elastic, the coefficient will be greater than one. When a percent price change occurs quantity demanded responds strongly there will be a large change in quantities consumers purchase. There is price sensitive in this scenario. If price elasticity of demanded is inelastic the coefficient will be less than one. When a percent price change occurs quantity demanded does not respond strongly then there is a slight change in quantities consumers will purchase. There a weak price sensitive in this scenario. Lastly, if price elasticity of demanded is unit elastic the coefficient will be equal to one. Whenever there is a percent change in price there is an equally matched percent change in quantity demanded. This scenario is rare.

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.
