- I am not a pro, but it goes something like this. In order to be
- rational, it follows you must maximize something. Also, the
- operational definition of rationality is maximizing an objection
- function subject to all available information. Implicitly, it is
- assumed that you use all available information in an efficient way,
- and that the model of the economy is known. This ensures you don't
- keep on making the same mistakes or acting on nominal and not real
- values.
-
- Bounded rationality says that there are costs to obtaining the
- information or maximizing the objective function. Thus, we are not
- "rational" but nearly so.
-
- Another approach is to alter the assumption that the model of the
- ecomy is known, and that in fact it has to be learned. This literature
- attempts to discover the process of learning. It turns out that
- economy is complicated enough, then people can make the same mistakes
- over and over and "Not one man in a million" can tell you where you
- went wrong....
