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.

BALANCE OF PAYMENTS A comprehensive set of accounts that tracks the flow of currency and other monetary assets coming in to and going out of a nation. These payments are used for international trade, foreign investments, and other financial activities. The balance of payments is divided into two accounts -- current account (which includes payments for imports, exports, services, and transfers) and capital account (which includes payments for physical and financial assets). A deficit in one account is matched by a surplus in the other account. The balance of trade is only one part of the overall balance of payments set of accounts.
