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.

FOUR-SECTOR KEYNESIAN MODEL A Keynesian model of the macroeconomy that includes all four macroeconomic sectors, the household sector, the business sector, the government sector, and the foreign sector.

This model provides the complete Keynesian representation of the macroeconomy, including the export-import interaction between the domestic economy and the foreign sector. Equilibrium is identified as the intersection between the C + I + G + (X - M) line and the 45-degree line. Two related variations are the two-sector Keynesian model and the three-sector Keynesian model.
