Davis demonstrates that industry lobbying, legislative demands, and international politics influence which countries and cases appear before the WTO. Democratic checks and balances bias the trade policy process toward public lawsuits and away from informal settlements. Trade officials use legal complaints to manage domestic politics and defend trade interests. WTO dispute settlement enables states and domestic groups to signal resolve more effectively, thereby enhancing the information available to policymakers and reducing the risk of a trade war. Davis establishes her argument with data on trade disputes and landmark cases, including the Boeing-Airbus controversy over aircraft subsidies, disagreement over Chinese intellectual property rights, and Japan's repeated challenges of U.S. steel industry protection. In her analysis of foreign trade barriers against U.S. exports, Davis explains why the United States gains better outcomes for cases taken to formal dispute settlement than for those negotiated. Case studies of Peru and Vietnam show that legal action can also benefit developing countries.
