COMMODITY EXCHANGE: A financial market that trades the ownership of various commodities, such as wheat, corn, cotton, sugar, crude oil, natural gas, gold, silver, and aluminum. The two biggest commodity exchanges in good old U. S. of A. are the Chicago Board of Trade and the Chicago Mercantile Exchange. Unlike, let's say a grocery store where commodities physically trade hands, commodity exchanges trade only legal ownership. This is much like a stock market, which trades the ownership of a corporation, but leaves the factory at home. Commodity markets offer two basic sorts of trading -- spot (immediate delivery of a commodity) and futures (delivery of a commodity at a future date).

AVERAGE-MARGINAL RULE: An intriguing, extremely useful mathematical relationship between an average measure and it's corresponding marginal measure, for example average product and marginal product, or average total cost and marginal cost. When the marginal measure is greater than the average measure, then the average measure increases. Alternatively, when the marginal measure is less than the average measure, then the average measure decreases. In addition, when the marginal measure is equal to the average measure the average measure doesn't change. See also | average product | marginal product | average total cost | average variable cost | marginal cost | average revenue | marginal revenue | average factor cost | marginal factor cost | average revenue product | marginal revenue product |

INDUCED GOVERNMENT PURCHASES Government purchases that depend on income or production (especially national income and gross domestic product). That is, changes in income induce changes in government purchases. Induced government purchases reflect the observation that the government sector (especially state and local governments) is inclined to use tax revenue, which increases with income, for purchases. They are measured by the marginal propensity for government purchases (MPG) and are reflected by the positive slope of government purchases line. The alternative to induced government purchases is autonomous government purchases, which do not depend on income.

[What's This?]
Today, you are likely to spend a great deal of time at a dollar discount store looking to buy either several magazines on fashion design or a package of 3 by 5 index cards, the ones without lines. Be on the lookout for jovial bank tellers.
