G: The standard abbreviation for government purchases by the governement sector, especially when used in the study of macroeconomics. This abbreviation is most often seen in the aggregate expenditure equation, AE = C + I + G + (X - M), where C, I, and (X - M) represent expenditures by the other three macroeconomic sectors, household, business, and foreign.

TWO-SECTOR INJECTIONS-LEAKAGES MODEL A variation of the Keynesian injections-leakages model that includes the two private sectors, the household sector and the business sector. This variation, often termed the saving-investment model or private sector injections-leakages model, captures the interaction between induced saving (and indirectly induced consumption expenditures) and autonomous investment expenditures. This model provides an alternative to the two-sector aggregate expenditures (Keynesian cross) analysis of the macroeconomy, including equilibrium, disequilibrium, and the multiplier. Equilibrium is identified as the intersection between the saving line and the investment line. Two related variations are the three-sector injections-leakages model and the four-sector injections-leakages model.
