Jack can reduce his pollution at $300/ton of carbon dioxide and Jill can reduce her pollution at $250/ton of carbon dioxide. Would it most likely be inefficient to reduce both of their pollution emissions by an equal amount? Multiple choice question. Yes, because the cost of reducing consumption varies between Jack and Jill. Jack should reduce his emissions by more to achieve efficiency. No, because both pay their fair share. Yes, because the cost of reducing consumption varies between Jack and Jill. Jill should reduce her emissions by more to achieve efficiency. No, because the cost of reducing consumption does not matter in terms of efficiency
