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.

TWO-SECTOR, TWO-MARKET CIRCULAR FLOW A simple circular flow model of the macroeconomy containing two sectors (business and household) and two markets (product and factor) that illustrates the continuous movement of the payments for goods and services between producers and consumers. The payment flow between the two sectors and two markets is conveniently divided into four segments representing consumption expenditures, gross domestic product, factor payments, and national income. More advanced models containing additional flow segments are two-sector, three-market circular flow; three-sector, three-market circular flow; and four-sector, three-market circular flow.
