What happens to the aggregate quantity demanded in nominal terms over this interval? Using the formula for price elasticity of demand (the ratio of the percentage change in the quantity of a good demanded to a given percentage change in the quantity of a good demanded to given percentage change in its price), what is the elasticity of aggregate demand over this interval? • Show less
