The Trans-Pacific Partnership (TPP) between 12 Pacific Rim countries has generated the most intensive political debate about the role of trade in the United States in a generation. The TPP is one of the broadest and most progressive free trade agreements since the North American Free Trade Agreement (NAFTA). The essays in this Policy Analysis provide estimates of the TPP's benefits and costs and analyze more than 20 issues in the agreement, including environmental and labor standards, tariff schedules, investment and competition policy, intellectual property, ecommerce, services and financial services, government procurement, dispute settlement, and agriculture. Through extensive analysis of the TPP text, PIIE scholars present an indispensable and detailed "reader's guide" that also sheds light on the agreement's merits and shortcomings.
