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.
答案
参考答案：C
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.
