Comparing tests of the theory of exhaustible resources

The empirical relevance of Hotelling’s exhaustible resource theory has been tested with primarily negative results. Tests have been performed on various resources, at different levels of aggregation, with varying market structures, and over different time periods. Consequently, it is difficult to draw any general conclusions concerning the theory’s applicability in explaining producer behavior, given the assumptions and restrictions implicit in the data and tests. This paper compares test results when the implicit restrictions associated with the data are removed. Employing a single data set we compare the results for four published tests. Even with this uniform data set, two approaches reject the theory while two do not.
