Principles of Microeconomics / Unit 2 MIC 0110 short lesson, about 20 seconds
Shift Versus Movement Along
Captions available
The idea
A change in the good's own price moves along its curve, a change in quantity demanded or supplied. Anything else changing shifts the whole curve, a change in demand or supply.
In practice
A sale moves along the demand curve; a heat wave shifts demand for ice cream.
Where people slip
The good's own price never shifts its own curve; quantity demanded means the curve stayed put.
