With monopoly, consumer surplus would be the area below the demand curve and above P m R. Part of the reduction in consumer surplus is the area under the demand curve between Q c and Q m; it is contained in the deadweight loss area GRC. This right over here is our dead weight loss. This market inefficiency is represented by the following formula: Q is the difference in the quantity demanded. The domain of this cookie is owned by Rocketfuel.

As a result, the market fails to supply the socially optimal amount of the good. Fair-return price and output: This is where P = ATC.
