This book presents an integrated theory of firms' strategies and two types of policies, namely environmental policies, and merger control policies. It develops a framework to examine the intricate relationship between merger and acquisition (M&A) incentives, merger control policy, environmental policies, and firms' sustainability practices. The chapters highlight the importance of policy coordination to underscore the link between M&A and environmental externality, and the link between merger policy and environmental policy. Drawing together related fields that are seldom linked in the literature, this volume offers a comprehensive and authoritative reference for scholars, graduate students, and policymakers.
