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.

BROWN PRAGMATOX
Your compete MICRO*scope for today

You are the type of person who is the poster child for the word "frugal," and you might even buy the poster if it cost less. Family and friends never, never, never ask your advice about the latest fashions, and rightly so. Today, you are likely to spend a great deal of time surfing the Internet trying to buy either decorative garden figurines or a wall poster commemorating last Friday (you know why). Be on the lookout for florescent light bulbs that hum folk songs from the sixties. You should consider shopping at stores or businesses beginning with the letter T, but do not buy any products with a serial number or product code containing the number 934856. Your preferred shopping venue is thrift stores. Your special symbol is the comma (,).


Is this You?

As a Brown Pragmatox, you are down-to-earth and practical. You are hard working and industrious. You are frugal to the point that you might even refrain from making a purchase that you really, really need. Doing so often causes problems down the road. You definitely go with function over form and substance over style.


This isn't me! What am I?
BANK PANIC

An economy-wide problem in the financial sector and the banking industry that triggers an economy-wide business-cycle contraction or even depression. Bank panics were common throughout the 1800s and early 1900s, during which time they where the primary cause of business-cycle downturns. Bank panics usually involved bank runs that spread from bank to bank throughout the economy.

Fact 4: Our Monopolized Markets

Our pedestrian's jaunt through the economy is not, unfortunately, an unrestrained shopping spree for confectioneries, spark plug tools, and Houston, Texas. We have other important errands to run. At the moment we need to hike over to Shady Valley's exclusive provider of cable television services, the Merciless Monolithic Media Masters Cable Television Company, Inc., to inquire about a mysterious fee that appeared last month's bill.

The good news is that the Merciless Monolithic Media Masters (the 4M people) Cable office is a mere 2 miles (3 kilometers for the metrically inclined) from the Shady Valley Central Town Sprawling Hills Shopping Mall. A hop, skip, and a moderately long jump later, our excursion through the economy takes us to the front door of the 4M Cable Television Company where I hope to discover why last month's cable bill included a $3,569 charge for something called "The Vacation Channel." I didn't even know I had a vacation channel. (But, I'm sure it's a great channel, and if I don't have it, then I will certainly subscribe. Please don't disconnect me.)

Of course, because this an afternoon workday, the doors of the 4M office are locked. I can almost make out, through the expensive stained glass windows, what appears to be several Merciless Monolithic Media Masters Cable Television employees, with champaign bottles in hand, dancing on expensive mahogany desks. Let's not disturb them. As they say in the cable business, an upset worker is a disconnected customer.
