Passage:
In classical economics, the concept of “invisible hand” describes the self-regulating nature of markets. Adam Smith suggested that individuals pursuing their own interests unintentionally benefit society by allocating resources efficiently. Modern critics argue that market failures, such as monopolies or externalities, limit this self-regulation. Behavioral economists further suggest that humans do not always act rationally, undermining traditional assumptions. Despite these critiques, the principle of the invisible hand remains influential in policy debates and economic theory. Some economists argue that certain regulations can complement, rather than replace, market forces. Empirical studies show that minimal interventions in competitive markets often lead to better outcomes than heavy-handed regulation. Understanding these nuances is essential for applying classical economic ideas to contemporary policy.
