LAW OF COMPARATIVE ADVANTAGE: A basic principle that states every nation has a production activity that incurs a lower opportunity cost than that of another nation, which means that trade between the two nations can be beneficial to both if each specializes in the production of a good with lower relative opportunity cost. While this law is fundamental to the study of international trade, it also applies to other activities, especially the specialization and the division of labor.

ABSTRACTION METHODS: Abstraction is the process of simplifying the complexities of the real world by ignoring (hopefully) unimportant details, especially (for our purposes) while doing economic analysis. Three common methods of actual, real world abstraction used in economic theories are words, graphs, and equations. Words can be misunderstood. Graphs are a little more precise. And equations tend to be the most precise of the three.

This isn't me! What am I?

Helping spur the U.S. industrial revolution, Thomas Edison patented nearly 1300 inventions, 300 of which came out of his Menlo Park "invention factory" during a four-year period.
