Principles of Macroeconomics / Unit 2 MAC 0104 short lesson, about 20 seconds
Supply and Quantity Supplied
Captions available
The idea
Supply is the whole relationship between price and the amount sellers are willing to offer. Quantity supplied is the amount at one particular price.
In practice
The supply curve slopes upward, so higher prices bring more onto the market.
Where people slip
The same distinction as on the demand side: supply is the curve, quantity supplied is a point on it.
