The spread of financial crises and trade conflicts show the necessity of a new political architecture for the world eco-nomy. As cross-border economic flows and private actors' mobility grow, national economic policy and international organizations do not seem to live up to the expectations. Which rules will shape globalization in the 21st century? The book explains the need for new rules and the divergence of national attitudes towards global economic governance. It covers the role of states in negotiating international trade, in regulating the banks and in promoting trilateralism. It investigates the role of business by assessing its increased power in writing the rules for self-regulation and in influencing the public sphere. Also, international organizations are analysed as standard setters and regional institutions are examined as blueprints for public and private authority on the global scale. Thus, the book answers the question on how the changes brought by globalization are addressed on the national, regional, multilateral and transnational levels.
