Step-by-step explanation:
The concept of the invisible hand, introduced by Adam Smith, is a metaphor used to describe the mechanisms through which beneficial social and economic outcomes may arise from the self-interested actions of individuals. It suggests that when individuals pursue their own self-interests in a market economy, the cumulative effect of their actions can lead to positive outcomes for society as a whole.
