PIE CHART: A circular graph divided into wedges that is commonly used to present the division of a total among parts. The circular "pie" represents the total value and each slice represents the portion distributed to each category. Pie charts are a handy way to present information, but are not well suited for more involved economic analysis.

Consumer Demand
This lesson discusses the basics of consumer demand theory, especially the notion of utility. Utility is the fancy-schmancy economic term that means satisfying wants and needs. The purpose of this lesson is to set the stage for a behind-the-scenes look at the demand-side of the market. Because the prices buyers are willing to pay for the goods depend on the utility, an understanding of demand requires an understanding of utility. - The first unit of this lesson, Demand Theory, introduces the concept of utility and previews the relation between utility, consumer decision making, and demand.
- In the second unit, Total Utility, we take a look at the first of two key technical notions of utility are used to examine the relation between utility and demand.
- The third unit, Marginal Utility, presents and discusses the second of the two technical notions of utility, and the most important notion underlying demand.
- The fourth unit, The Curves, illustrates the total utility and marginal utility concepts with handy graphs.
- The fifth unit, Taking Stock, then wraps up this lesson with an extended preview of the relation between utility and demand.

SLOPE, LONG-RUN AGGREGATE SUPPLY CURVE The long-run aggregate supply (LRAS) curve is a vertical line with an infinite slope, reflecting the independent relation between the price level and aggregate real production. A higher price level is associated with the same real production as a lower price level. This is the real production generated when resources are fully employed, that is, full-employment production.
