This volume provides a clear, comprehensive introduction to social constructivism for use in making sense of global governance. By elucidating processes of social construction-how different actors come to be authoritative rule-makers, how diverse norms and practices come to define global rules, and how the clash of ideas and identities shape global rule-making-Ba and Hoffmann provide a useful approach for those seeking to grasp (or even steer) the processes and varied arrangements of global governance.
