How Individuals Make Economic Decisions
In life decisions are made every day. Ideas and the decisions that follow those ideas are the choices individuals make each day.   It is implied, most people make sound rational choices and decisions.

Unfortunately, everyone does not make rational decisions all the time.   Rational behavior is a practical way to understand decisions people make.   The four principles of individual decision-making are: People Face Trade-Offs, People Think Marginally, People Respond to Incentives, and People weigh the Cost and Benefits (Mankiw).
Trade-offs occurs when a people must give up something to receive something else.

People respond to incentives, whether it is positive or negative.   An incentive is something that induces a person to act, such as the prospect of a punishment or a reward. Marginal change in cost or benefit encourages people to respond to the incentive positive or negative (Hubbard & O'Brien, 2010).   People act from a variety of motives, such as spiritual...
