The Role Of Business in Global Governance offers a theoretically innovative and empirically rich analysis of the new political role of corporations in the co-performance of governance functions beyond the state. It takes stock of the different types of private contributions to transnational governance as an expression of the new interplay between the state, the business sector and civil society. It provides an understanding, grounded in theory, of the potential and the limits of private self-regulatory arrangements as components of future global governance architecture. It investigates under what conditions which kinds of private contributions to governance beyond the state can be expected; and offers a comprehensive evaluation of the effectiveness and legitimacy potential of private contributions to global governance. By conceptualizing the role change of business actors as corporate norm-entrepreneurship and employing a comprehensive set of criteria for its evaluation, this book goes much further than other studies in the field.
