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.

Market Demand
This lesson on demand offers a little insight, not only into my Stuffed Amigo buying behavior, but into the purchases of a wide range of other goods, too, even goods that aren't cute and cuddly. In fact, this demand topic does more than offer insight into buying behavior. It's also one half of the market analysis -- the other half being supply. And market analysis is one of the most widely used tools in the study of economics. Economists explain a lot of economic phenomenon using markets. But to use markets, we need demand, which brings us back to this lesson. - In the first unit of this lesson, Buying Basics, we examine the basic concept of demand. While you've likely come across the term demand before, we'll see the specific way the term is used in economics.
- The second unit, Law of Demand, then takes a look at the law of demand, which is one of the most important and fundamental economic principles that we'll encounter.
- As we move on to the third unit, Demand Curve, our attention turns to the demand curve, which is the graphical embodiment of demand.
- In the fourth unit, Determinants, we examine how the five basic demand determinants that cause the demand curve to shift from one location to another.
- And finally in the fifth unit, Scarcity, we make a connection between demand and the fundamental problem of scarcity.

INTERMEDIATE GOODS Goods (and services) that are used as inputs or components in the production of other goods. Intermediate goods are combined into the production of finished products, or what are termed final goods. Unlike final goods, intermediate goods will be further processed before sold as final goods. Because gross domestic product seeks to measure the market value of final goods, and because the value of intermediate goods are included in the value of final goods, market transactions that capture the value of intermediate goods are not included separately in gross domestic product. To do so creates the problem of double counting.
