SCARCITY RENT: The marginal opportunity cost imposed on future generations by extracting one more unit of a resource today. Scarcity rent is one of two costs the extraction of a finite resource imposes on society. The other is marginal extraction cost--the opportunity cost of resources employed in the extraction activity.
