Summary and Final Tasks


In this lesson, we introduced the concept of a market system, and our core tool for analysis of markets, the supply and demand diagram.

We examined in detail the origins and underpinnings of one half of this market model: the demand curve.

At this point, you should be able to perform the following tasks:

  • Explain what a market-based economy is, and what the most common alternative form of economic organization is.
  • Define and understand what is meant by the term, "declining marginal utility."
  • Identify the parts of a supply and demand diagram.
  • Read an individual demand schedule and use it to draw an individual demand curve.
  • Understand that a demand curve is a functional relationship between two things: the quantity of goods (Q) that is demanded by consumers at a given price (P). Demand is not a constant, but a line that has changing Q for changing P.
  • Amalgamate individual demand curves to obtain a market demand curve.
  • Understand what the term "price elasticity of demand" refers to.
  • Be able to calculate a price elasticity of demand.
