LRAS CURVE: The abbreviation of long-run aggregate supply, which is the long-run relation between real production and the price level, holding all ceteris paribus aggregate supply determinants constant. The LRAS curve is one of two curves that graphical capture the supply-side of the aggregate market; the other is the short-run aggregate supply curve (SRAS). The demand-side of the aggregate market is occupied by the aggregate demand curve. The vertical LRAS curve captures the independent relation between real production and the price level that exists in the long run.

Kinked-Demand Curve
|
|
|
- How and why oligopoly firms have rigid prices can be illustrated with the use of the kinked-demand curve.
- A kinked-demand curve is a demand curve with two distinct segments with different elasticities that join to form a kink.
- The two segments of a kinked-demand curve are:
- A relatively more elastic segment for price increases.
- A relatively less elastic segment for price decreases.
- The most striking feature of this curve is that it comes it three parts:
- One part corresponds with the relatively more elastic demand curve for price increases.
- The second part corresponds with the relatively less elastic demand curve for price decreases.
- The third part is the vertical line connecting these two segments.
- This disjointed marginal revenue curve is the key to oligopoly price rigidity.

UNEMPLOYED The condition in which a resource (especially labor) is NOT actively engaged in a productive activity, but IS actively seeking employment. This general condition forms the conceptual basis for one of the three categories used by the Bureau of Labor Statistics (BLS) when classifying an individual's labor force status--employed persons. The other two BLS categories are employed persons and not in the labor force.

[What's This?]
Today, you are likely to spend a great deal of time wandering around the shopping mall hoping to buy either a T-shirt commemorating Thor Heyerdahl's Pacific crossing aboard the Kon-Tiki or a wall poster commemorating the 2000 Olympics. Be on the lookout for telephone calls from former employers.
