23
Q

Formula for CPED and Midpoint CPED

A

Qy2-Qy1 Qy2-Qy1
———— ——————
Qy1 (Qy2+Qy1)/2
————– —————————–
Px2-Px1 Px2-Px1
————- ————
Px1 (Px2+Px1)/2

23
Q

How should you use CPED?

A

Treat it like this, QDy is what we want to know how it is affected by increases/decreases in the price of QDx
Example:
Badminton Racket=QDx and Px
Shuttlecock=QDy and Px
we can phrase it like “We want to know how the change in the price of badminton racket affects the demand of Shuttlecock”
if we reverse it, it becomes “We want to know how the change in the price of shuttlecock affects the demand of badminton Racket”
