How to use deadweight loss
Deadweight loss is primarily a technical term in economics referring to the reduction in total economic welfare due to market inefficiency, most commonly caused by taxes, monopolies, or price controls that prevent markets from reaching competitive equilibrium. The third sense (useless cargo or weight) is now archaic and rarely used in contemporary English. The term is essential in microeconomic analysis and policy discussions, where it quantifies the cost of economic distortions.
Common phrases

A common mistake
Learners sometimes confuse deadweight loss with simple redistribution of wealth; deadweight loss specifically refers to the net loss of total benefit to society, not merely a transfer of resources from one party to another.
