ABSTRACTION: Simplifying the complexities of the real world by ignoring (hopefully) unimportant details while doing economic analysis. Abstraction is often criticized because it's, well, it's JUST NOT REALISTIC. However, when done correctly (ignoring things that JUST DON'T MATTER), then the pursuit of knowledge is greatly enhanced by abstraction. For example, when travelling cross country along a high-speed interstate highway, a paper road map is a handy tool. It shows towns and cities along the way, the major intersections, rest stop locations, and other important points of interest. However, it ignores unimportant details. It doesn't realistically show the location of every tree, bush, or blade of grass. Why bother? This information won't enhance your road trip.

Lesson 5: Market Demand | Unit 5: Scarcity
|
Page: 19 of 20
|
Demand is closely related to the scarcity problem, especially unlimited wants and needs.- Scarcity arises because society has limited resources but unlimited wants and needs.
- The connection between demand and scarcity is:
- The demand side of the markets comes directly from the unlimited wants and needs side of the scarcity problem, and
- The supply side of the market comes from the limited resources side of the scarcity problem.

STRUCTURAL UNEMPLOYMENT Unemployment caused by a mismatch between workers' skills and the skills needed for available jobs. Structural unemployment essentially occurs because resources, especially labor, are configured (trained) for a given technology but the economy demands goods and services using another technology. Employers seek workers who have one type of skill and workers seeking employment have a different type of skill. This mismatch in skills, largely the result of technological progress, creates unemployment of the structural variety. Structural unemployment is one of four unemployment sources. The other three are cyclical unemployment, seasonal unemployment, and frictional unemployment. Frictional and structural unemployment are the two components of natural unemployment.
