There has been a resurgence of interest, in many parts of the world, in problems of multilevel government finance. Recent and ongoing political and economic developments raise questions about the role of the nation, subnational governments, and supranational public authorities in the provision and financing of public-sector programs. This paper presents an overview of these developments that may assist in understanding some of the motivation behind the articles presented in this special issue and in appreciating some of their potential applications. The articles are briefly summarized, and some issues that remain on the agenda for future research are identified.
