Overview
This lecture explains Adam Smith's concept of the "invisible hand" in economics and discusses differing perspectives on its impact.
Adam Smith and the Invisible Hand
- Adam Smith introduced the "invisible hand" metaphor in the 18th century to describe how self-interest can lead to public benefit.
- The theory suggests individuals acting for personal gain unintentionally create an effective economic system.
- In free markets, prices drop when goods are abundant and rise when scarce, encouraging production and importation.
Free Market Efficiency
- Buyers and sellers focus on their own profits and losses, seeking the best deals available.
- Their self-interested decisions lead to an efficient allocation of resources.
- This market-driven system is considered superior to government-controlled economies by many economists.
Criticism and Alternative Views
- Economists like Friedrich Hayek and Milton Friedman used the invisible hand argument to oppose trade restrictions.
- Critics argue that the invisible hand is not always beneficial, especially for those who are underpaid or unemployed.
- Some describe negative market effects as an "invisible boot" rather than a helping hand.
Key Terms & Definitions
