The concept of the invisible hand is associated with which economist?

• A. Karl Marx
• B. David Ricardo
• C. Carl Menger
• D. Adam Smith

Answer: (D)

The invisible hand describes how self-interested actions in a free market, guided by price signals and competition, coordinate economic activity and allocate resources efficiently without central planning. Adam Smith is the economist most closely associated with this metaphor, illustrating how individuals pursuing their own gain can unintentionally promote societal well-being through voluntary exchange and competitive markets. Marx emphasizes class struggle and planning in an economy, not the invisible-hand idea; Ricardo focuses on labor value and trade, not the coordinating mechanism of markets; Menger contributed to marginal utility and price theory but did not popularize the invisible-hand concept. So, the economist linked to the invisible hand is Adam Smith.
