THREE-SECTOR INJECTIONS-LEAKAGES MODEL A variation of the Keynesian injections-leakages model that includes the three domestic sectors--the household sector, the business sector, and the government sector. This model provides an alternative to the three-sector aggregate expenditures (Keynesian cross) analysis of government stabilization policies, especially how fiscal policy changes in government purchases and taxes can be used to close recessionary gaps and inflationary gaps.
