PARETO IMPROVEMENT: Based on the Pareto efficiency criterion, the notion that an action improves efficiency if it is possible for one person to benefit without anyone else being harmed. A Pareto improvement is possible if the economy has idle resources or market failures. With idle resources, more production is possible to help some without hurting others. With market failures, corrective actions can eliminate deadweight loss that can then be use for benefits economy-wide. A contrasting condition for attaining efficiency is the Kaldor-Hicks improvement.
