An economist tells you that demand is not the same thing as quantity demanded. What is the distinction?
ADemand is the point on the curve at one price
BQuantity demanded is the entire demand curve itself
CDemand is the curve; quantity demanded is one point on it
DThe two terms mean exactly the same thing
Answer & Solution
Correct answer: C. Demand is the curve; quantity demanded is one point on it
1. Demand describes the whole relationship between a range of prices and the quantities buyers want at each price.
2. That relationship is shown as a demand curve or a demand schedule.
3. Quantity demanded is only one value read off that curve at one particular price.
4. So demand is the curve, and quantity demanded is a single point on it, which rules out options A and B.
