Assuming that all gold extracted is sold in the same year (cannot be stockpiled for later sale) , how will the regulation affect the user cost? A) It will have no effect on the user cost. B) The effect on the user cost cannot be determined. C) The user cost will rise because the rate of extraction will rise. D) The user cost will become zero because they will not be able to extract in the future.
