Optimal extraction with grade variation and endogenous reserves
This paper describes and analyzes a simple model of a competitive firm engaged in non-petroleum resource extraction. It allows for grade variation within a mineral deposit, treats as endogenous the determination of reserves and distinguishes between ore throughput and metal output. The central result is a characterization of the optimal intertemporal extraction profile. A numerical example illustrates the main principle of quality selection.
