Government interventions should be viewed as a collection of different bodies with their own goals and tools, not just one entity. Interest groups can influence these interventions, leading to extra costs. To make regulations more efficient, transaction costs need to be minimized. Regulatory contracts should balance rent and efficiency, and regulators should be independent, autonomous, and accountable. Short-term contracts may be better for ensuring autonomy. Choosing regulators based on professional criteria may not always prevent capture, as they may have ties to the industry they regulate. Including both executive and legislative branches in the selection process can help reduce the risk of capture.
