MegaReg is a research project about the potential transformation of global and national regulation through megaregional agreements such as the Trans-Pacific Partnership (TPP), the Transatlantic Trade and Investment Partnership (TTIP), the Trade in Services Agreement (TiSA), the Regional Comprehensive Economic Partnership (RCEP), and the Tripartite Free Trade Area (TFTA). A particular focus lies on their impact on non-party countries as well as excluded and under-included groups. We gratefully acknowledge the support of the NYU Global Institute for Advanced Study.
