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.

STOCK MARKET: A financial market that trades ownership shares in corporations--corporate stock. The three best known, national stock markets in the United States are the New York Stock Exchange, the American Stock Exchange, and the National Association of Securities Dealers. There are also a few regional markets--the Chicago, Philadelphia, and Pacific exchanges are the most notable that trade stock on a smaller scale. Other countries that use corporations to produce stuff, all of the industrialized ones, also have stock markets. The biggest and most worthy of attention are in Tokyo, London, Toronto, Frankfurt, and Paris. Stock markets play a vital role in our economy, making it possible for businesses to raise the large sums of money needed for investment.

ASSUMPTIONS, CLASSICAL ECONOMICS Classical economics, especially as directed toward macroeconomics, relies on three key assumptions--flexible prices, Say's law, and saving-investment equality. Flexible prices ensure that markets adjust to equilibrium and eliminate shortages and surpluses. Say's law states that supply creates its own demand and means that enough income is generated by production to purchase the resulting production. The saving-investment equality ensures that any income leaked from consumption into saving is replaced by an equal amount of investment. Although of questionable realism, these three assumptions imply that the economy would operate at full employment.
