This means that a negative number is converted to a positive number, and a commodity is considered elastic when PED > 1. However, because the PED formula always produces a negative result, the minus sign becomes unnecessary - it is therefore ignored. When the result of the formula is between 0 and -1, the price of a commodity is said to be inelastic, whereas a result of score of -1 or lower represents inelasticity. Price elasticity of demand = % change in quantity demanded ÷ % change in priceĪccording to laws of demand (whereby an increase in price will result in a decrease in demand, and vice versa), the PED formula will always produce a negative result. There are several methods for calculating price elasticity of demand, but one of the most common measures is the ‘percentage method', which uses the following formula: The concept of ‘price elasticity of demand’ measures how much demand for a commodity is affected by its price. ‘Price elasticity’ is usually used refer to to the relationship between price and demand. Alternatively, if price of a commodity has little impact on supply and demand, it is described as inelastic. If the price of a good or service easily affects supply or demand, it is described as elastic. Price elasticity measures the extent to which this applies to a specific commodity, and looks at how much the price of a product or service affects supply or demand. In microeconomic theory, it usually assumed that an increase in price will lead to lower demand and higher supply. Sign up now and try Debitoor free for seven days.
