Pigouvian Tax

… a core term used in Economic Analysis and Atlas102


A Pigouvian tax is a tax levied on a market activity that has a significant External Cost.

Alex Tabarrok (reference below) illustrates how the imposition of a Pigouvian Tax, equal to the external cost, makes the Private Cost plus tax equal to the Social Cost, and thus moves the price and quantity to the Efficient Equilibrium.
