  • The public interest theory suggests that regulatory agencies are established to address market failures and promote the overall well-being of society. These agencies are tasked with correcting issues such as information asymmetries, negative externalities, and the provision of public goods, which the free market often fails to adequately address.

  • One of the key criticisms of the public interest theory is the concept of regulatory capture, where regulatory agencies become influenced by the industries they are meant to regulate. In such cases, the agencies may end up serving the commercial or political interests of special interest groups rather than the broader public interest. Additionally, the degree to which regulatory agencies actually serve the public interest is an ongoing debate, as there may be instances where the agencies' actions do not align with the intended goals of the public interest theory.

The ongoing debate surrounding the public interest theory and the role of regulatory agencies highlights the complexities involved in balancing the need for regulation with the potential for regulatory agencies to be influenced by special interests.
