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 thinks of shopping as a necessity, but not the most important thing that you will do today. Family and friends generally call the local library when they can't find you, and rightfully so. Today, you are likely to spend a great deal of time browsing about a thrift store hoping to buy either a coffee table shaped like the state of Florida or storage boxes for your summer clothes. 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 D, but do not buy any products with a serial number or product code containing the number 589797. 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?

MARGINAL COST OF SEARCH The incremental cost incurred by additional search effort is the marginal cost of search. Marginal cost of search, also termed marginal search cost, is comparable to marginal cost of short-run production analysis. Marginal cost of search increases with an increase in search effort and is represented by the marginal cost of search curve. This is one half of the efficient information search decision. The other is marginal benefit of search.

Shopping Around For RETAIL PRICESIt's time for another one of our frequent stops at Mr. Market Super Food Discount Store, this time to check out the story behind retail prices. As consumers, we spend a large fraction of our nonworking, nonsleeping lives wandering grocery stores aisles, searching clothing store racks, and surveying department store displays for the right product at the right price. How do we know, like the name of the long-running game show, if "The Price is Right?" How are retail prices set and do they really tell us the value of a product?
