  • Surely thats wrong, you have put a tax on it, rasing their MPC, but this doesnt equal MSC therefore there is still a market failure and thus you havent corrected the martet at all? Ali A2 student

  • @alih15 it is a correction as long as the size of the welfare loss created by the negative externality has been reduced. It does not have to be entirely removed to be a correction. The size of the tax will dictate how much the welfare loss gets reduced. A big enough tax could remove the welfare loss altogether.

  • can you use supply and demand to show this? and just say that ''if we include external cost the supply curve will shift to the left''?

  • @ErebusTV Hello- no you cannot use D and S curves - they are different things! You really have to think about the purpose of the curves and what points on the curves mean to realise the differenc between the two kinds of curves. Regards, PAJ Holden
