MARGINAL COST CURVE: A curve that graphically represents the relation between marginal cost incurred by a firm in the short-run product of a good or service and the quantity of output produced. This curve is constructed to capture the relation between marginal cost and the level of output, holding other variables, like technology and resource prices, constant. The marginal cost curve is U-shaped. Marginal cost is relatively high at small quantities of output, then as production increases, declines, reaches a minimum value, then rises. This shape of the marginal cost curve is directly attributable to increasing, then decreasing marginal returns (and the law of diminishing marginal returns).

PRICE INDEX A measure of the average of a group of prices calculated as a ratio to prices in a given time period (that is, a base year). A price index is primarily used to compare relative prices, or changes in the group prices over time. Such an index is a handy indicator of overall price trends. Two common price indexes that surface in the study of macroeconomics are the Consumer Price Index (CPI) and the GDP price deflator. Both are used to indicate the macroeconomy's average price level and to estimate the inflation rate. The Dow Jones Industrial Average (the Dow), Standard & Poor's 500, and the NASDAQ are well-known indexes of stock market prices.

Today, you are likely to spend a great deal of time looking for the new strip mall out on the highway looking to buy either a flower arrangement for your aunt or a birthday greeting card for your uncle. Be on the lookout for bottles of barbeque sauce that act TOO innocent.

"Consult not your fears, but your hopes and your dreams. Think not about your frustrations, but about your unfulfilled potential. Concern yourself not with what you tried and failed in, but with what it is still possible for you to do. " -- Pope John XXIII
