Unitary elastic means that elasticity is equal to 1. In case of price elasticity of demand, e = 1 implies that the percentage change in quantity demanded is equal to the percentage change in price of the commodity. Demand Elasticity is obviously negative. Elasticity = percentage change in quantity demanded / percentagechange in price. Even though perfect real life examples would be tough to list, a close example can be a 1$ increase in price of a good leads to a unit fall in its quantity demanded.
SIZE:Economists calculate elasticity as the percent change in quantity (supplied or demanded) divided by the percent change in price. If the resulting number is greater than 1, the supply or demand of the good is considered elastic. If it is less than 1, it is inelastic. EFFECTS:Whether the demand or supply of a particular good is elastic or inelastic depends in part on how essential it is to most consumers. Goods that are necessities for consumers everyday lives are more inelastic.
