YIELD CURVE: A curve plotting the yields (or returns) on securities with different maturity lengths. The standard yield is for U.S. Treasury securities with lengths ranging from 90 days to 30 years. The five maturity lengths are usually 90 day, 180 day, 2 year, 5 year, 10 year, and 30 year. The shape and slope fo the yield curve indicates the state of the economy and what's likely to come. A normal yield curve has a slight positive slope, with slightly higher yields for longer maturity securities. A steep yield curve suggests the end of a contraction and beginning of an expansion. An inverted, or negatively sloped yield curve is the sign of an upcoming contraction.

Elasticity and Demand
Elasticity is the relative responsiveness of one variable to changes in another variable. Economists find this notion of elasticity quite useful in the study of markets. In this lesson, we examine the basics of demand elasticity, especially the price elasticity of demand. - The first unit of this lesson, An Overview, gets us started with a review of several concepts related to elasticity and demand.
- In the second unit, The Continuum, we take a close look at how the five elasticity alternatives are reflected by demand curves.
- The third unit, Measurement, runs through some numbers for measuring the price elasticity of demand, and how elasticity values related to a straightline demand curve.
- The fourth unit, Determinants, examines how the three determinants of elasticity affect the elasticity coefficient.
- The fifth unit and final unit, Other, closes this lesson by introducing examine three related elasticity measures.

BARTER A method of trading goods, commodities, or services, directly for one another without the use of money. Barter was the first type of market exchanged undertaken by human civilization as people advanced beyond self sufficiency in the satisfaction of their wants and needs. Modern economies still use a modest amount of barter to allocate resources. The key to a barter exchange is a double coincidence of wants, in which each side of the exchange wants what the other side has and has want the other side wants. A barter exchange tends to be less efficient that exchanges involving money.
