SPATIAL: A modifying term used to indicate a connection or relation to space, and by inference the study of urban and regional economics, as suggested by the term spatial differentiation (which means differences in the concentration of economic activity across space). This term is commonly used to make people some exceedingly intelligent by asking questions like "Did you consider spatial factors in your analysis?" However, in so doing be careful that the word is pronounced "spatial", not "special." This just confuses the situation.

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.
