DEMAND ELASTICITY AND TOTAL EXPENDITURE: The notion that price-induced changes in total expenditure for a good (price times quantity) depends on the relative price elasticity of demand. In particular, for relatively elastic demand (1 < E < ∞) changes in price cause total expenditure to change in the opposite direction. An increase in price causes total expenditure to fall and a decrease in price causes total expenditure to rise. For relatively inelastic demand (0 < E < 1) changes in price cause total expenditure to change in the same direction. An increase in price causes total expenditure to rise and a decrease in price causes total expenditure to fall. For unit elastic demand (E =1) price changes do not cause any change in total expenditure. Total expenditure is the same whether price increases or decreases.

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.

Today, you are likely to spend a great deal of time at a flea market wanting to buy either a how-to book on home remodeling or a tall storage cabinet with five shelves and a secure lock. Be on the lookout for florescent light bulbs that hum folk songs from the sixties.
