KALDOR-HICKS IMPROVEMENT: 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.

Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
