This paper tests the Hotelling Valuation Principle (HVP) for natural r
esources using data from oil and gas (pure plays' such as royalty trus
ts and master limited partnerships, The results support the HVP which
specifies that the value of any mineral reserve may be predicted by th
e market price of the resource, net of extraction costs, Regression re
sults also indicate that a Box-Cox transformation of variables provide
a better means of estimating the functional relationship between the
value of an exhaustible natural resource and its market price. (C) 199
