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.

The financial markets are one of three primary sets of macroeconomic markets. The other two are product markets and resource markets.
