HERFINDAHL-HIRSHMAN 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.

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.
