REAL ECONOMY: The physical side of the economy dealing with goods, services and resources. This side is concerned with using resources to produce the goods and services that make the satisfaction of wants and needs possible. This should be contrasted with the paper economy, or financial side of the economy.

FOUR-SECTOR INJECTIONS-LEAKAGES MODEL

A variation of the Keynesian injections-leakages model that adds the foreign sector to the three domestic sectors--the household sector, the business sector, and the government sector. This variation adds the foreign to the three domestic sectors (household, business, and government) in the three-sector model and provides an alternative to the four-sector aggregate expenditures (Keynesian cross). It 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 S + T + M line and the I + G + X line. Two related variations are the two-sector injections-leakages model and the three-sector injections-leakages model.
