Module 2 discussion
The Law of One Price states that equivalent investment
opportunities trading in different competitive markets will have the same
price. Yet, one can find examples where that rule seems to be violated. It is a
well-known fact that Americans pay a much higher price for most prescription
drugs than people in most other countries. Also, the price (when adjusted for
exchange rates) for the same make and model of automobile varies greatly across
different countries. Furthermore, the price of a barrel of crude oil varies
between locations. For example, on October 12, 2012, the price for Brent crude
oil produced in Europe was $114.21 and the price for West Texas Intermediate
(WTI) crude oil produced in Texas was $91.86.
Do these three cases demonstrate that the Law of One Price
is false? Why or why not?
