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.

This investment explanation of business-cycle instability rests on the proposition that the seeds of each subsequent business-cycle phase are planted during the current phase. An expansion creates the conditions that cause a contraction and a contraction creates the conditions that cause an expansion. This explanation suggests a critical role for government intervention and stabilization policies to correct the business-cycle problems of inflation and unemployment.
