9. Which of the following products are likely subject to positive network externalities?
I. A car
II. A fax machine
III. A set of golf clubs
IV. An email account
A. II and IV only
B. II and III only
C. I and III only
D. II only
E. III and IV only
“A” answer is right.
Actually I would add also all others – because if there would be only one golf club – not so much players would be available and professionals, trainers, etc. The same with car – nobody would build a roads for your car only. So all of listed things would be useless if nobody else would be able to use them (if they wouldn’t be available for them). Just for ones mentioned “A” attributes of network externality are most expressed.
