Question

Suppose we have the following information concerning the printed magazine and digital magazine subscription markets:

Printed Magazine Subscription Price0=$20 Digital Magazine Subscription Quantity0=216 Printed Magazine Subscription
Price1=$13.40 Digital Magazine Subscription Quantity1=208 Question:
What is the cross-price elasticity of demand between printed and digital magazine subscriptions?

Answer 1

Cross-price elasticity of demand between printed and digital magazine subscriptions is 8.91.

Step-by-step explanation:

Percentage change in price of Printed Magazine Subscription = ((Printed Magazine Subscription Price1 - Printed Magazine Subscription Price0) / Printed Magazine Subscription Price0) * 100 = (($13.40 - $20) / $20) * 100 = -33%

Percentage change in quantity of Digital Magazine Subscription Quantity = ((Digital Magazine Subscription Quantity1 - Digital Magazine Subscription Quantity0) / Digital Magazine Subscription Quantity0) * 100 = ((208 - 216) / 216) * 100 = -3.7037037037037%

Cross-price elasticity of demand between printed and digital magazine subscriptions = Percentage change in price of Printed Magazine Subscription / Percentage change in quantity of Digital Magazine Subscription Quantity = -33% / -3.7037037037037% = 8.91

Note: The relationship between printed and digital magazine subscriptions is that they are substitutes because the cross-price elasticity between them is positive. That is, an increase in the price of printed digital magazine makes consumer to switch to and buy more of digital magazine which is a substitute.
