This special issue of Business History Review, which explores the governance of global capitalism, was guest-edited by Grace Ballor, Bocconi University, and Sabine Pitteloud, UniDistance Suisse. Professors Ballor and Pitteloud provide an introduction that outlines the main themes of this issue and summarizes key literature on the history of businesses and international institutions. This issue also features articles by Ann-Kristin Bergquist and Thomas David on the role of the International Chamber of Commerce in shaping global environmental regulation, by Véronique Dimier and Sarah Stockwell on the efforts of the British government to influence the flow of multilateral aid within the European Economic Community, and by Vanessa Ogle on international anti-tax avoidance measures advocated by a covert international working group known as the Group of Four. In addition to co-organizing the issue, Grace Ballor contributes an article on emission standards in the European Union. The special issue also includes a roundtable on capitalism and global governance, with essays by Patricia Clavin, Nicolás M. Perrone, Neil Rollings, and Quinn Slobodian, and a reflection piece by Rawi Abdelal, entitled “Firms, Rules, and Global Capitalism.” Readers will also find a highly relevant review essay by Laura Phillips-Sawyer, “Revisiting Interwar Global Economic Governance: Technocrats, Sovereignty, and the Perennial Problem of Legitimacy in Global Governance,” that looks at new books by Nicholas Mulder and Jamie Martin.
