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.

DOUBLE COINCIDENCE OF WANTS: The requirements of a barter exchange that each trader has want the other wants and wants what the other has. Because everyone doesn't necessarily want everything, the lack of double coincidence of wants is a major obstacle in barter exchanges, especially for complex, modern economies. While double coincidence of wants is also essential for exchanges involving money, it's such an inherent trait of money we don't think twice about it. By its very nature as a generally accepted medium of exchange, everyone WANTS money.

AUTOMATIC STABILIZERS

Taxes and transfer payments that depend on the level of aggregate production and income such that they automatically dampen business-cycle instability without the need for discretionary policy action. Automatic stabilizers are a form of nondiscretionary fiscal policy that do not require explicit action by the government sector to address the ups and downs of the business cycle and the problems of unemployment and inflation.
