Premium Supply and demand Price elasticity of demand
price elasticity of demand is a measure of how much the quantity demanded of a good responds to a change in the price of that good‚ computed as the percentage change in quantity demanded divided by the percentage change in price. When demand is inelastic (a price elasticity less than 1)‚ a price increase raises total revenue‚ and a price decrease reduces total revenue. When demand is elastic (a price elasticity greater than 1)‚ a price increase reduces total revenue‚ and a price decrease increases

total-revenue test is a way to determine if a product is elastic (a decrease in price that will increase the total revenue and vice-versa) or inelastic (a decrease in price that will cause the total revenue to decrease and vice-versa) (McConnell‚ 2009‚ p. 116‚ para. 6). Businesses use this test to determine if they have a product that is elastic or inelastic by moving the prices of the products up and down and determining if the revenue is increasing or decreasing. For example‚ if a product currently

a slight change in price leads to a sharp change in the quantity demanded or supplied. Usually these kinds of products are readily available in the market and a person may not necessarily need them in his or her daily life. On the other hand‚ an inelastic good or service is one in which changes in price witness only modest changes in the quantity demanded or supplied‚ if any at all. These goods tend to be things that are more of a necessity to the consumer in his or her daily life. To determine

relationship between the change in quantity demanded of a particular good and a change in its price relates to prices sensitivity. If a small change in price is accompanied by a change of quantity demanded‚ the product will be elastic. A product that is inelastic is when a large change in price is accompanied by a small change in the quantity demanded. Elasticity is sensitive to change in price‚ the degree to which demand for a good or service‚ in this case the flowers I am selling‚ varies with its price
