ECONOMY: The system of production, distribution, and consumption of goods and services that a society uses to address the problem of scarcity. The essential task of an economy is to transform resources into useful goods and services (the act of production), then distribute or allocate these products to useful ends (the act of consumption). Virtually all economies accomplish this task through a combination of decisions made through voluntary market exchanges and involuntary government rules and regulations.

SAVING-INVESTMENT MODEL A variation of the Keynesian injections-leakages model that includes the two private sectors, the household sector and the business sector. This variation, more formally termed the two-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.
