In this timely and insightful book, Laura Maxim evaluates the use of socio-economic analysis (SEA) in the regulation of potentially carcinogenic, mutagenic, and toxic chemicals. Retracing the history of the use of cost-benefit analysis in chemical risk policies, this book presents contemporary discourse on the political success of SEA. Informed by empirical research, theoretical analysis, and professional experience in implementing EU Regulation on the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH), Maxim proposes a new form of risk regulation called ‘regulatory co-management’, of which SEA has become a convenient tool. Chapters outline the controversy surrounding cost-benefit analysis in the US, the history of chemical regulation in Europe since 1967, and the construction and institutionalization of the European Chemicals Agency’s (ECHA) socio-economic guidelines. The book concludes by analyzing legal, political, and ethical criticisms of the role of SEA in the authorization of chemicals such as lead chromate, chromium trioxide, and sodium dichromate. With direct relevance to ongoing debates about the revision of EU chemicals policy, this unique book will be essential reading for practitioners of socio-economic analysis and stakeholders involved in REACH. It will also be beneficial to academics and students of environmental governance and regulation, European politics and policy, and industrial economics.
