➤ Why doesn’t a change in production cost shift the demand curve?
Production costs affect supply decisions, not consumers’ preferences. When firms face higher costs, the supply curve shifts and market price may rise, which causes a movement along the demand curve (change in quantity demanded). Only factors that alter consumer willingness or ability to buy at all prices shift the demand curve.
