:''Not to be confused with
Hotelling's law.''
'Hotelling's rule' is defining the net price path as a function of time while maximising rent in the time of fully extracting a
non-renewable natural resource. The maximum rent is also known as 'Hotelling rent' or 'scarcity rent' and is the maximum
rent that could be obtained while emptying the stock resource.
'Hotelling's rule' is the result of analysis of non-renewable
resource management by
Harold Hotelling, published in the ''Journal of Political Economy'' in
1931. A similar result was published by L. C. Gray in
1914, considering the case of a single mine owner. Hotelling's result shows that in an efficient exploitation of a non-renewable and non-augmentable resource, the percentage change in net-price per unit of time should equal the
discount rate in order to maximise the present value of the resource capital over the extraction period.
The simple rule can be expressed by the equilibrium situation representing the optimal solution.
:
,
when P(t) is the unit
profit at time t and
is the discount rate.
The
economic rent obtained is an
abnormal rent, often referred to as
resource rent, since it generates from a situation where the resource owner has open access to the resource for free. The resource rent therefore equals the
shadow value of the natural resource or
natural capital.
The concept of Resource rent also includes biological and other
renewable resources.
