HERFINDAHL INDEX: A measure of concentration of the production in an industry that's calculated as the sum of the squares of market shares for each firm. This is an alternative method of summarizing the degree to which an industry is oligopolistic and the relative concentration of market power held by the largest firms in the industry. The Herfindahl index gives a better indication of the relative market control of the largest firms than can be found with the four-firm and eight-firm concentration ratios.

GREEN LOGIGUIN
Your compete MICRO*scope for today

You are the type of person who always looks at both sides of any issue, because every issue has two sides. Family and friends don't understand how you can watch a baseball game and a movie at the same time. Today, you are likely to spend a great deal of time going from convenience store to convenience store trying to buy either a remote controlled World War I bi-plane or a wall poster commemorating Thor Heyerdahl's Pacific crossing aboard the Kon-Tiki. Be on the lookout for telephone calls from former employers. You should consider shopping at stores or businesses beginning with the letter N, but do not buy any products with a serial number or product code containing the number 615171. Your preferred shopping venue is strip malls. Your special symbol is the equal sign (=).


Is this You?

As a Green Logiguin, you seek a balance in life and your market activities. You are logical and reasonable, always seeking to weigh costs and benefits, pros and cons, ups and downs, ins and outs, goods and bads. You are the embodiment of yin and yang. You know that there are two sides to every story and every market exchange. Sometimes you buy. Sometimes you sell. You search out the best deals, with the highest quality and lowest price.


This isn't me! What am I?
ELASTIC SUPPLY

The general supply relation in which relatively small changes in price cause relatively large changes in quantity supplied. Small changes in price cause relatively large changes in quantity supplied or the percentage change in quantity supplied is larger than the percentage change in price. This characterization of elasticity is most important for the price elasticity of supply. Elastic supply is one of two general elasticity relations for supply. The other is inelastic supply.

Planning On SOCIAL SECURITY?

This may be the greatest day of my life. The musical group to top all musical groups -- The Strollers -- has just released its latest CD with a song that's certain to be a foot-tapping classical. Of course, you know the song of which I speak -- "Sidewalking." Let's stop into the Musical Sound CD Emporium in the Shady Valley Central Town Sprawling Hills Shopping Mall and fulfill my dreams. Everyone in Shady Valley, however, does not share my joy. As the seventeen year old Emporium clerk, Alicia Hyfield, completes my transaction, she confesses more than a bit of disgruntlement over here just-issued paycheck. A little investigation reveals some displeasure with the size of the FICA deduction. Her disgruntlement isn't lessened to know that this is for the government's social security program that's suppose to provide a source of income in her golden years. She seems more than a bit skeptical of ever seeing any returns. Maybe we can alleviate her concerns (and mine) with a quick run through social security.

The word "fiscal" is derived from a Latin word meaning "moneybag."
"My philosophy of life is that if we make up our mind what we are going to make of our lives, then work hard toward that goal, we never lose - somehow we win out."
