An idealized human being considered to operate rationally and seeking to maximize personal happiness and utility is referred to as an economic man. This type of man is the standard by which all other men are measured. Rational choice theory, a branch of economics that studies how humans make decisions, assumes that people act according to certain universal laws called "human nature." In other words, rational actors will always choose what will benefit them most in any given situation. The word "economic" here means "having to do with wealth or the acquisition of money." As such, an economic man is one who is concerned with achieving wealth through successful investment management. Different authors have given different definitions for what it means to be an economic man. However, they all share two traits: rationality and self-interest. An economic man makes choices based on what will benefit him/her financially in the long run. They don't give away money to charity just because it feels good. Instead, they only do work for pay. An economic man doesn't waste resources nor does he/she take risks needlessly. He/she lives within their means and tries not to spend more than they earn. In conclusion, being an economic man is about using your brain before you open your wallet.
