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.

Hair Dyeing Fad Reflects Recession


Dyed hair is making a comeback. L'Oréal, the world's no.1 hair dye manufacturer, saw the sales of its hair color products surge some 30 percent in September compared to a year earlier. The sales of unusual dye including red, copper and metallic colors soared 47 percent. Experts make connections between the trend and the recession. A beauty specialist said people seek to escape reality in a recession, and dyed hair offers a kind of fantasy image. During the 1997-98 Asian financial crisis, dyed hair was also fashionable. More middle-aged people also dye their hair in an effort, experts say, to look younger and stand a better chance in the depressed job market.
It is a global phenomenon. The U.K. Telegraph called the phenomenon a "gold rush" and quoted celebrity hairdresser Andrew Barton as saying that many people are dyeing their hair blond to find an antidote to the depression. In the U.S., the term "hair dye index" was newly coined to show the link between the economy and dyeing hair. People's hair color becomes lighter as economy worsens. Hair dyeing is a counter-cyclical economic indicator roughly synonymous with an inferior good.
