Hotelling's rule
Hotelling's rule defines the net
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. 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.
This concept was the result of analysis of non-renewable
fossil fuels (coal, oil, gas).[1]
Devarajan and Fisher note that a similar result was published by L. C. Gray in 1914, considering the case of a single mine owner.
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 δ 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. In other words, the resource rent is the resource royalty or resource's net price (price received from selling the resource minus costs. In this case costs are zero). The resource rent therefore equals the shadow value of the natural resource or natural capital.
