Over time, the scope of public finance, as a branch of economics, has expanded with the changing role of governments. When considered from the positive as well as normative perspectives, this subject is no longer confined to the understanding of only public revenue or taxation, public expenditure, and public debt. Issues related to climate finance and climate change, environmental federalism, and the trans-jurisdictional implications of global public goods have emerged as themes of critical relevance. When it comes to public financial management, several new areas have become relevant for policy, including the understanding of fiscal transparency, legislative control over borrowing, and the establishment of independent fiscal institutions such as fiscal councils. Fiscal Policy and Public Financial Management presents a range of contributions dealing with the evolving frontiers of research on the subject. It highlights specific themes related to direct and indirect taxes, tax evasion, public expenditure and debt, fiscal and environmental federalism, fiscal transparency, budget management, climate change and climate finance, and public sector investment appraisals. The diverse array of issues covered in this volume thus provides important analytical insights on the complexity and challenges of fiscal management in India and the emerging issues in public financial management, including climate finance.
