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.

LERNER INDEX: The difference between price (p) and marginal cost (mc) as a fraction of price, that is [p-mc]/p. The Lerner index is usually taken as an indicator of market power because the larger the index, the larger the difference between price and marginal cost, that is, the larger the distance between the price and the competitive price. The Lerner index depends on the elasticity of demand. The Lerner index is also called the price-cost margin.

MARGINAL COST CURVE

A curve that graphically represents the relation between the marginal cost incurred by a firm in the short-run product of a good or service and the quantity of output produced. This curve is constructed to capture the relation between marginal cost and the level of output, holding other variables like technology and resource prices constant. Three related curves are average total cost curve, average variable cost curve, and average fixed cost curve.
