A graphical representation showing the cost of extracting resources at various production rates, typically illustrating increased costs as resources become scarcer.

Marginal Extraction Costs

The additional costs incurred in extracting one more unit of a resource, which can increase as the resource becomes more scarce.

User Costs

Expenses related to the use of a product or service, including maintenance, operation, and depreciation.
