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.

DOUBLE COINCIDENCE OF WANTS: The requirements of a barter exchange that each trader has want the other wants and wants what the other has. Because everyone doesn't necessarily want everything, the lack of double coincidence of wants is a major obstacle in barter exchanges, especially for complex, modern economies. While double coincidence of wants is also essential for exchanges involving money, it's such an inherent trait of money we don't think twice about it. By its very nature as a generally accepted medium of exchange, everyone WANTS money.

ARC ELASTICITY

The average elasticity for discrete changes in two variables. The distinguishing characteristic of arc elasticity is that percentage changes are calculated based on the average of initial and ending values of each variable, rather than initial values. Arc elasticity is generally calculated using the midpoint elasticity formula. The contrast to arc elasticity is point elasticity. For infinitesimally small changes in two variables, arc elasticity is the same as point elasticity.

In his older years, Andrew Carnegie seldom carried money because he was offended by its sight and touch.
"A leader, once convinced that a particular course of action is the right one, must . . . be undaunted when the going gets tough."
