Exploration and Exhaustible Resources: The Microfoundations of Aggregate Models
The appropriate specifications for aggregate extraction and exploration cost functions are derived from a disaggregate model of the search for low-cost deposits of an exhaustible resource. The common practice of combining the no-discovery extraction cost function with exploration is shown to result in a misspecified model for which the total cost of extracting the resource is not well defined. The widely accepted prediction that the anticipated discovery of low-cost deposits results in a U-shaped price path appears to be an artifact of this misspecification. For the authors' properly specified cost functions, the predicted resource price always rises.
