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.

PURPLE SMARPHIN
Your compete MICRO*scope for today

You are the type of person who is generally thinking about three different things at the same time. Family and friends get irritated when you explain, for the umpteenth time, the difference between a partial derivative and a total derivative. Today, you are likely to spend a great deal of time browsing through a long list of dot com websites wanting to buy either a pair of blue silicon oven mitts or a coffee cup commemorating the 2000 Olympics. Be on the lookout for celebrities who speak directly to you through your television. You should consider shopping at stores or businesses beginning with the letter H, but do not buy any products with a serial number or product code containing the number 768855. Your preferred shopping venue is the Internet. Your special symbol is the exclamation point (!).


Is this You?

As a Purple Smarphin, you are the brightest and most intelligent person you know. And that goes for shopping, too. You know exactly what you want. You know exactly what it costs. You know exactly when and where to buy. But, of course, shopping is only one of the many activities that attracts your intellectual attention. You shop when you need to and buy if have to, but shopping is not the end all of your life.


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

What a bank owes, including most notably customer deposits. Bank liabilities are typically listed on the right-hand side of a bank's balance sheet. Bank assets, what a bank owns, are listed on the left-hand side of a bank's balance sheet. Net worth is the difference between assets and liabilities. The most important liability category of most bank is checkable deposits, which is part of the economy's M1 money supply. The largest liability category includes other types of deposits (especially savings deposits, certificates of deposit, and money market deposits) that enter into the M2 and M3 monetary aggregates.

Laying The Groundrules On REGULATION

Our journey has brought us to the "Rs," which means, among other things, that my feet are trifle bit sore. Fortunately, we've also found ourselves at the front door of the Good Time Pharmacy. (Isn't coincidence wonderful?) My quick shopping trip for a pair of cushioned insoles, analgesic rub, and an ankle wrap is lengthened, however, by crossing paths with the normally quiet Stella von Steincamp. Stella, the pharmacist and proprietor of the Good Time Pharmacy, has taken the opportunity of our meeting to voice a rather vehement complaint over a new Shady Valley city government pharmaceutical regulation mandating the use of disposable rubber gloves when preparing and dispensing medicine. She is livid! Her primary complaint (among several) is that the cost of this regulation will send her pharmacy onto a short path into bankruptcy. In the interest of maintaining pharmaceutical services for the residents of Shady Valley, I think, would should explore this topic of government regulation.
