Ten Key Principles of Economics

1. Everything has a cost. There is no free lunch. There is always a trade-off.
2. Cost is what you give up to get something. In particular, opportunity cost is cost of the tradeoff.
3. One More. Rational people make decisions on the basis of the cost of one more unit (of consumption, of investment, of labor hour, etc.).
4. Incentives work. People respond to incentives.
5. Open for trade. Trade can make all parties better off.
6. Markets Rock! Usually, markets are the best way to allocate scarce resources between producers and consumers.
7. Intervention in free markets is sometimes needed. (But watch out for the law of unintended effects!)
8. Concentrate on productivity. A country’s standard of living depends on how productive its economy is.
9. Sloshing in money leads to higher prices. Inflation is caused by excessive money supply.!!
10. Caution: In the short run, falling prices may lead to unemployment, and rising employment may lead to inflation.

As the latest attempt to pass an energy bill goes up in smoke, there is one thing for certain, a lot of ignorance surrounds this issue. Click on the link above to get an understandable description of the cap and trade system. Every economist worth his salt would tell you that the answer to global warming has to be disincentives to produce the causes of global warming. A pigouvian tax, for instance, increases the private cost of the action to equate or surpass the social cost. The cost of polluting is currently not a deterrant.

In an extreme case of externalities, farmers in Europe are levied a tax on their cows because of the methane released when the bovine...uh, you know...fart. Cows are considered significant contributors to the greenhouse gases that impact our atmosphere, but this pigovian maneuver has farmers steamed.
