Economics is a subset of psychology - psychology applied to
matters of money, assets, liabilities, production, buying
and selling, that sort of thing.

That's not even in the ball park! Have you ever read an economics
text?

Yes, I have. I had to read one to help my ex-wife pass an
econ class. She didn't understand it, but I did.

You may *think* you did, but you didn't.

The closest economics comes to being "psychological" (and it's about
as "close " as the North Pole is to the South Pole) is in making the
assumption that people always behave "rationally." I.e., that
entrepreneurs maximize profit by equating marginal cost with marginal
revenue and that consumers "equate at the margin" so that the last
penny spent on every good and service provides the same amount of
"utility" (want-satisfaction).

You just described applied psychology

No, I didn't. Psychologists *study* human behavior. Economic theory
is based on an *assumption* about behavior, an extremely naive one,
and proceeds from there, with no study of behavior to investigate that
assumption.

I don't recall any economist claiming that people always behave rationally.

See above.

Your point being...???

My point is, your original post is incorrect, as well as what you said
here. (BTW, "being" is not a verb.)

Are you sure that book you read with your wife wasn't about HOME
economics?
