DIAMOND-WATER PARADOX: The perplexing observation that water, which is more useful than diamonds, has a lower price. If price is related to utility, how can this occur? This paradox was first proposed by classical economists in the 19th century and was subsequently used as a stepping stone for developing the notion of marginal utility and the role it plays in the demand price of a good. The paradox is magically cleared up with an understanding of marginal utility and total utility. People are willing to pay a higher price for goods with greater marginal utility. As such, water which is plentiful has enormous total utility, but a low price because of a low marginal utility. Diamonds, however, have less total utility because they are less plentiful, but a high price because of a high marginal utility.

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.
