Since the price elasticity of demand is negative for the vast majority of goods and services (unlike most other elasticities, which take both positive and negative values depending on the good), economists often leave off the word "negative" or the minus sign and refer to the price elasticity of demand as a positive value (i.e., in absolute value terms).

Price elasticity of demand (PED) measures the change in the demand for a product or service in response to a change in its price. With most goods, an increase in price leads to a decrease in demand – and a decrease in price leads to an increase in demand. When there is a large change in demand after a price change, that good is considered to have '...
PED is calculated by dividing the percentage change in quantity demanded by the percentage change in price. The value resulting from that calculation indicates the responsiveness of demand.
You can tell if price elasticity of demand is elastic or inelastic from the value provided by the price elasticity of demand formula. If the value from that equation is:
The PED calculations above will give you a number that indicates whether demand for a good is elastic or inelastic: 1. If the demand for a good is elastic, the change in demand is greater than the change in price. 2. If it’s inelastic, the change in demand is smaller than the change in price.
Generally speaking, demand will decrease when price increases, and demand will increase when price decreases. That means that the price elasticity of demand is almost always negative (since demand and price have an inverse relationship). Because there is almost always one decreasing variable, the resulting value will be negative. It’s important to ...

With a downward-sloping demand curve, price and quantity demanded move in opposite directions, so the price elasticity of demand is always negative. A positive percentage change in price implies a negative percentage change in quantity demanded, and vice versa. Sometimes you will see the absolute value of the price elasticity measure reported.
In Fig 6.1, at each point between A and B, shown on the demand curve, price drops by $1.50 and the number of units demanded increases by 2. The slope is –1.5/2 = – 0.75 along the entire demand curve and does not change. The price elasticity, however, changes along the curve.
Cross-Price Elasticity of Demand. Cross-price elasticity measures how the demand for one good changes in response to a change in the price of another good. A positive cross-price of elasticity indicates the presence of substitutes since the increase in the price of one good increases the demand for a different good.
