WEALTH PYRAMID: A handy technique that many get-rich-quick schemes use to transfer a little wealth from a lot of people into the overflowing pockets of a few. In works in this manner--A person or business establishes a multi-level pyramid of investors, employees, or "distributors." Each level is responsible for recruiting the next level beneath it. The trick is that each distributor at one level recruits several distributors into the next lower level in an ever-expanding fashion. Each recruit transfers a little, teeny, tiny bit of their own wealth to the next higher level. In that each higher level has fewer members, that little, teeny, tiny bit of wealth accumulates rapidly, making those at the top incredibly well-off.

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.
