Restoring Public Debt Sustainability represents the first comprehensive survey of a new generation of independent fiscal institutions, established to promote transparency in public finances through real-time monitoring of the soundness of budgetary policymaking. The chapters, written by headsof the institutions, as well as distinguished policy analysts and academics, explore the rationale and experience of these fiscal watchdogs. Consequently, useful lessons and implications are drawn for the design and practical operation of such institutions. The timeliness of the volume isunderscored by the potential role of fiscal watchdogs in containing the public debt crisis that has engulfed a number of countries. Specifically, the recent proliferation of these institutions has been largely in response to the need for enhancing policy credibility of highly indebted governments infinancial markets, and for strengthening the quality of economic governance - especially in the current European context. The first part of the book deals with key analytical and institutional issues: the political environment, the scope and limits of these institutions, and a comparison to delegation of monetary policymaking to an independent body. The second part contains case studies of institutions that were bornas a result of domestic developments. The third part presents the experience of institutions in Sweden, Hungary, and the United Kingdom, whose origins can be traced directly or indirectly to an earlier or a recent external financial crisis. The chapters are written from a multidisciplinary(economic, financial, political, legal) perspective, intended for academics, researchers, and practitioners alike.
