***B*** ∻Key Concept∻ ⚹Change in Quantity Demanded vs. Change in Demand⚹ ∻Explanation∻ ⚹A change in quantity demanded ($\Delta Q_{d}$) refers to a movement along the demand curve due to a change in the price of the good itself, while a change in demand ($\Delta D$) refers to a shift of the entire demand curve caused by factors other than the price of the good, such as income, expectations, preferences, number of buyers, and prices of other goods.⚹◊What factors can cause a shift in the demand curve according to macroeconomics?⍭ Generate me a similar question◊
