This volume focuses on economic institutions defined as rules and organizational arrangements that, if they govern the design and implementation of fiscal and monetary policies, can better align those policies with long-run citizen interests. Specifically, the economic institutions covered are those that promote more sustainable fiscal management, adequate implementation of monetary policy, and more resilient financial systems. On fiscal management, the book covers public revenue administrations, public financial management systems, public debt management institutions, fiscal rules, medium-term fiscal frameworks, independent fiscal councils, and the design features of sovereign wealth funds. While pension schemes are not a fiscal institution, they are also analyzed because of the fiscal burden and contingencies that these systems may entail. In terms of institutions that support effective monetary policy, the focus is on the importance of central bank independence and transparency. On financial systems, the book analyzes the relevance of financial regulation and supervision to promote more stable and efficient markets that are better suited to confront challenges and more resilient against external shocks. Some institutional enhancements that foster access to credit and deeper financial systems are also analyzed.
