The regulation of financial markets holds a significant place in economic theory. Classical economists such as Adam Smith and David Ricardo believed in the self-regulating nature of markets, advocating for minimal state intervention. They argued that market forces naturally determine prices and allocate resources efficiently. Modern economic theories, including institutionalism view the efficiency of the state and institutions as essential for the effective functioning of financial markets. Regulatory economics examines financial regulation and its impact on economic efficiency, suggesting that excessive regulation stifles innovation, while insufficient regulation leads to financial instability. Therefore, a balanced regulatory approach is necessary.
