An economist is someone who studies or works in the field of economics. Economics is the study of how people make choices to satisfy their wants.

According to Frédéric Bastiat:

"There is only one difference between a bad economist and a good one: the bad economist confines himself to the visible effect; the good economist takes into account both the effect that can be seen and those effects that must be foreseen."^[1]
