VERIFICATION: The hypothesis-testing step of the scientific method. Once an hypothesis is derived from a theory, it must be compared with real world data. This is the verification step. This verification can lead to support or refutation of the hypothesis. Enough support enables a hypothesis to become a principle. Refutation calls into question the theory implying the hypothesis.

Demand
This lesson on demand offers a little insight into the purchases of a wide range of goods. In fact, this demand topic is 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. And that brings us back to this lesson. - In the first unit of this lesson 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 then takes a look at the law of demand, which is one of the most important and most fundamental economic principles that we'll encounter.
- As we more on to the third unit, our attention turns to the demand curve, which is the graphical embodiment of the demand concept.
- In the fourth unit, we examine how the five basic demand determinants cause the demand curve to shift from one location to another.
- And finally in the fifth unit, we make a connection between demand and the fundamental problem of scarcity.

BALANCE ON SERVICES A subset of the balance of payments current account that records the difference between the payments received for exports of services to other nations and the payments made for the imports of services from other nations. The flow of payments is for intangible services, not for physical or tangible goods. The balance on services is thus appropriately divided into services exported and services imported. Two other subsets of the current account include the balance on merchandise trade and unilateral transfers. The commonly termed balance of trade is the sum of the balance on merchandise trade and the balance on services.
