    INJECTIONS LINE

    A graphical representation of the relation between the level of aggregate production and one or more injections. The three injections (non-consumption expenditures on aggregate production) are investment expenditures, government purchases and exports. The injections line sequentially adds, or layers, each of these three expenditures depending on the number of sectors used in the analysis (two, three, or four). The slope of the injections line depends on which if any of the expenditures are induced by aggregate production. The injections line is combined with the leakages line (containing saving, taxes, and imports) in the Keynesian injections-leakages model.
