Economics is a social science that describes how society produces and consumes goods and services. It is concerned with both efficiency (getting the most out of a fixed amount of resources) and distribution (who gains and who loses). The use of free markets as a mechanism of promoting efficiency has been touted by the majority of economists since the time of Adam Smith. His theory was that in free markets each individual, pursuing his or her own self-interests, will be led,
as if by some “invisible hand,” to produce an allocation that maximizes society's utility.
