It is commonplace for today's transnational enterprises to undertake political risk analysis when choosing foreign markets and creating entry strategies. Despite this, non-market elements of corporate strategy are less well researched than the traditional market-based perspectives. Providing comprehensive and leading edge overviews of current scholarship, this Companion surveys the current state of the field and provides a basis for improving our understanding of the non-market environment, encouraging new insights to improve strategies for enhancing a firm's performance and legitimacy. With a foreword by David Baron, the international team of contributors includes Jean-Philippe Bonardi, Bennet Zelner, and Jonathan Doh, who combine to create a book that is essential reading for students and researchers in business, management, and politics, including those interested in business regulation, environmental policy, political risk and corporate social responsibility.
