Economic Model

An economic model attempts to abstract from complex human behavior in a way that sheds some insight into a particular aspect of that behavior.  This process inherently ignores important aspects of real-world behavior, making the modeling process an art as well as a mathematical exercise.

The expression of a model can be in the form of words, diagrams, or mathematical equations, depending on the audience and the point of the model.

The Classic Economic Models collection emphasizes the role of diagrammatic economic models in describing optimizing behavior.
