In this video, we solve two problems for maximizing dynamic efficiency of a non renewable resource over two time periods. Hotelling's rule defines the net price path as a function of time while maximizing economic 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.
