This analysis of ‘globalised’ standard-setting processes draws together insights from law, political sciences, sociology and social anthropology to assess the authority and accountability of non-state actors and the legitimacy and effectiveness of the processes. The essays offer new understandings of current governance problems, including environmental and financial standards, rules for military contractors and complex public-private partnerships, such as those intended to protect critical information infrastructure. The contributions also evaluate multi-stakeholder initiatives (such as the Extractive Industries Transparency Initiative), and discuss the constitution of public norms in stateless areas. A synopsis of the latest results of the World Governance Indicator, arguably one of the most important surveys in the area today, is included.
