The Comprehensive Economic and Trade Agreement between the EU and Canada (CETA), proposed Transatlantic Trade and Investment Partnership between the EU and the US (TTIP), and the plurilateral Trade in Services Agreement (TiSA) between the EU and 22 other States have sparked a great deal of academic and public interest. This edited collection brings together leading experts in the field of international economic law to address the legal complexities of these treaties and provide an explanation of their core principles. In the first two chapters, this book examines changing conceptions of international economic law and the main motivations for negotiating mega-regional agreements. In nine further contributions, international experts examine sectoral issues such as the trade, investment, and dispute settlement procedures envisaged in these 'mega-regional' agreements. The book goes on to consider the progress made in intellectual property protection, the problems associated with data protection, human rights, labour, and environmental standards, issues of transparency and legitimacy, and the relationship between CETA, TTIP, and TiSA on the one hand and EU law on the other. It concludes with four chapters that discuss globalization and other fundamental questions surrounding these mega-regional agreements from economic, political science, and legal perspectives.
