Who is often credited with the idea of the "invisible hand" in economics?

The idea of the "invisible hand" is most notably associated with Adam Smith, who introduced this concept in his seminal works on economics, particularly in "The Wealth of Nations." This metaphor describes the self-regulating nature of the marketplace, wherein individuals pursuing their own interests can inadvertently promote the overall good of society. Smith argued that when individuals act in their own economic self-interest, they unintentionally benefit others and contribute to the economy’s efficiency and growth.

This concept is foundational in classical economics, suggesting that free markets can lead to positive outcomes without centralized control. Smith's insights laid the groundwork for modern economic theory and the belief in minimal government intervention in market activities. The other individuals listed, while significant in their contributions to economic thought, did not specifically develop the concept of the "invisible hand" in a similar context as Smith did.
