Answer:
Classification of events as Shifting the Aggregate Demand Curve or Causing Movement along the Curve:
a. = shifting the aggregate demand curve.
b. = causing movement along the demand curve.
Explanation:
When technological advances generate wealth in a broad range of industries, the movement along the demand curve denotes a change in both price and quantity demanded. Â This is obtainable because technological advances usually reduce costs of production and prices. The reduced price can increase demand. Â On the other hand, inflation that drops to nearly zero will cause a shift in a demand curve because the quantity demanded can increase with the price of the good remaining the same.
