deadweight loss
This term is a specialized technical expression used primarily in economics and public policy. It describes a specific type of inefficiency where the loss of consumer and producer surplus exceeds the revenue gained by the government through a tax, or the cost of a subsidy. It carries a negative connotation of waste and inefficiency.
Because it refers to a conceptual economic measurement, it is treated as an uncountable noun. You would not refer to "three deadweight losses" in a standard economic analysis; instead, you would discuss "the amount of deadweight loss" or "a significant deadweight loss" to describe the magnitude of the inefficiency.
Ý nghĩa
The loss of economic efficiency that occurs when the equilibrium for a good or service is not achieved or is artificially distorted, typically by taxes, subsidies, or price controls.
The imposition of a high tax on luxury goods often results in a significant deadweight loss as consumers reduce their purchases.
