In this video, you'll learn about what the "invisible hand" means in economics. The invisible hand is a metaphor for how self-interested individuals operate through a system of mutual interdependence in a free market economy. Adam Smith introduced the concept of the invisible hand in 1776. The invisible hand metaphor stipulates that voluntary trades in a free market produce unintentional and widespread benefits and that these benefits are greater than those of a regulated, planned economy.
