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).

With limited resources and unlimited wants and needs, a lot of opportunities are forgone, a lot of alternatives can't be pursued. This is the idea of opportunity cost. A definition: - Opportunity cost is the highest valued alternative foregone in the pursuit of an activity.
Three points related to this definition:- Foregone Alternative: Opportunity cost means NOT doing something else, not producing another good. Using resources to satisfy one want or need means they can't be used to satisfy another.
- Highest Valued: Opportunity cost is all about giving up the best alternative possible, the most satisfying. Any activity has many alternatives. Opportunity cost is not all of these alternatives, only the most preferred, the highest valued.
- Pursuit of an Activity: Using resources to produce goods that are consumed to satisfy wants and needs. The key economic activities foregone are production and consumption.

[What's This?]
Today, you are likely to spend a great deal of time looking for the new strip mall out on the highway hoping to buy either a rechargeable battery for your cell phone or a T-shirt commemorating the 2000 Olympics. Be on the lookout for bottles of barbeque sauce that act TOO innocent.
