Regulation exists in both the public and private sectors to manage risk and protect consumers. There are two main forms - traditional regulation by government agencies and self-regulation set by professional bodies and private organizations. While self-regulation is preferred by the private sector for its flexibility, there are questions around whether it can be fully trusted without oversight from government regulators. Effective regulation requires identifying risks in both foreseeable and unforeseen ways in order to manage industries where public and private interests intersect.
