Final answer:
Adam Smith believed in the invisible hand of the marketplace for regulating prices without government intervention.
Step-by-step explanation:
Adam Smith claimed that the "invisible hand" of the marketplace helped regulate prices without the need for government intervention. The concept of the invisible hand suggests that in a free market economy, the self-interest of individuals and businesses leads to an optimal allocation of resources and efficient functioning of the economy. This means that prices are determined through the interaction of supply and demand, rather than being set by government control.
