This chapter explores the interface between competition and consumer policies, law and institutions as it is emerging in ASEAN. It analyses the reasons for the traditional separation of these two fields, both generally and ASEAN in particular, and then explains the case for an integrated approach to policymaking and a coordinated approach to institutional design, pointing to international examples of such approaches. The chapter considers the evidence of integration and coordination in ASEAN to date, and considers reasons for the functionally silo-ed approach that has been exhibited in most member states thus far. It argues that increased recognition of the positive interdependencies between competition and consumer policies should be a key element of ASEAN’s future development, consistent with theories of networked governance, trading up and contextualised transplantation.
