Deadweight Loss

… a core term used in Economic Analysis and Atlas102

Definition

The Economist defines deadweight loss (or deadweight cost) as the extent to which the value and impact of a tax, tax relief, or subsidy is reduced because of side effects. (See Tax Revenue and Deadweight Loss.)

However, as noted by Alex Tabarrok (reference below) the term can also be applied to the loss associated with external costs, as illustrated below. (See Externality.)
