  • D. To set the quantity of pollution with tradable pollution permits, the regulator must know everything about the demand for pollution rights.
  • E. Pigovian taxes are more likely to reduce pollution to a targeted amount than tradable pollution permits.

Explanation

Both taxes and tradable permits can produce an efficient pollution outcome when properly designed, but permit allocation need not initially favor the lowest-cost reducers because trading reallocates permits. Taxes are generally more likely than permits to achieve a specified pollution price, not necessarily a specified quantity, so option b is the valid statement.
