Term Kaldor-Hicks improvement Definition: Based on the Kaldor-Hicks efficiency criterion, the notion that an action improves efficiency if the willingness to pay of those benefiting exceed the willingness to accept of those harmed. In other words, if those gains exceed those losses, or the benefits exceed the costs, then social welfare is improved and undertaking the action provides a net benefit to society. In other words, the winners can, in principle, compensate the losers for their loss, and still come out ahead. The actual compensation, however, is required. A contrasting condition for attaining efficiency is the Pareto improvement.
