This attempt to measure the efficiency of regulatory bodies is made mainly by identifying the presence or absence of the conditions required for them to operate. There is no consideration of the rectitude of regulators' decisions, the welfare effects of regulation, or cost-benefit analysis of it. The article summarizes attempts made to measure the efficiency of regulatory bodies in international organizations, scientific research and state regulatory systems. Attention is paid here primarily to branch regulation of network services. However, the analytical methods mentioned in the article are also used to examine competition-regulatory bodies.
