单选题 Which of the following statements about the economic rent to a natural resource is most accurate? A. The entire payment for a non-renewable natural resource is economic rent. B. A non-renewable natural resource earns economic rent only if demand for the resource is perfectly inelastic. C. The entire payment for a renewable natural resource is economic rent.

【正确答案】 C

【答案解析】When the supply curve is perfectly inelastic, as it is for a renewable natural resource, the entire payment for the resource is economic rent. When the supply curve is perfectly elastic, as with a non-renewable natural resource, none of the payment is economic rent.
