BARTER ECONOMY: An economy that trades goods and services using barter exchanges rather than money. Barter economies originally predated the invention of money, emerging out the early stage of self-sufficiency before giving way to the use of commodity money. However, barter economies occasionally surface in modern times, especially when the public loses confidence in the monetary unit during a government crises or a period of hyperinflation.

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.

In an economy that uses markets to exchange commodities, value is commonly indicated by price and measured by the economy's monetary unit.
