Efficient Equilibrium

… a core term used in Economic Analysis and Atlas102


Alex Tabarrok (reference below) describes the efficient equilibrium as the point at which private demand intersects the Social Cost curve. When there is a significant External Cost associated with the activity, the efficient equilibrium will be different from the Market Equilibrium, the intersection of demand and the supply curve  that reflects the Private Cost of provision. (See Externality.)
