Amidst the wave of privatization and "deregulation" across the globe, a new set of regulatory structures is being created. The fact that deregulation actually involves "re-regulation" has been acknowledged in the recent literature, but the tension between regulation and public participation has been understudied in these new structures. While some private markets need effective regulation to reduce transactions costs and ensure stable market rules, consumers need regulation that is responsive to, and protective of, their interests. Consumer participation, therefore, is an important component of effective regulation. Effective regulation must also consider collective national or public interests, including the well-being of corporations. Therefore, regulatory agencies need to be both independent from, and responsive to corporate, consumer, and public interests. This article will briefly examine the tension among the competing goals of regulatory independence and responsiveness, and then conduct a broad survey of the status quo of public participation in national regulatory structures for electricity in the Americas. Our case studies demonstrate a wide variety of institutional mechanisms for participation, yet we find that no existing system seems to embrace direct participation by a wide set of consumers. The problems are even more acute in developing countries. We conclude by looking at recent experiments and proposals to improve the levels of participation in regulatory decision making.
