In the tradition of the Asia Competitiveness Institute (ACI) at the Lee Kuan Yew School of Public Policy (LKYSPP), National University of Singapore (NUS), our research publications make a distinctive contribution to the literature by focusing on pertinent regional and national economic issues of the Association of Southeast Asian Nations (ASEAN) as one of our flagship projects. Combining leading-edge research methodologies with an extensive dataset, ACI has evaluated and tracked competitiveness for the 10 ASEAN members annually since 2000. In this edition, the competitiveness ranking and simulation study for the ASEAN-10 economies are improved and updated with 121 indicators across four environments.
