Summary

A unified treatment of the marginal cost of public funds, covering both its theoretical foundations and how the MCF concept can be used to analyze tax policy issues.

The marginal cost of public funds (MCF) measures the loss incurred by society in raising additional revenues to finance government spending. The MCF has emerged as one of the most important concepts in public economics; it is a key component in evaluations of tax reforms, public expenditure programs, and other public policies. The Marginal Cost of Public Funds provides a unified treatment of the MCF, carefully developing its theoretical foundations in a variety of contexts and describing its application to a wide range of policies—from excise taxes in Thailand to public sector borrowing in Canada and the United States.

The Marginal Cost of Public Funds develops the basic theory of the MCF within the framework of public economics and shows how it is related to the traditional measures of the efficiency loss from distortionary taxation. The MCF concept is then applied to the major sources of revenues for governments—sales and excise taxes, taxes on labor income, taxes on the return to capital, public sector borrowing, and intergovernmental grants. This book will be an essential reference for economists and public policy analysts both in and out of government. Exercises and recommendations for further reading at the end of each main chapter highlight its usefulness as a supplementary text in advanced undergraduate or graduate courses in public economics.

  • An estimate of the marginal cost of public funds (MCF) is critical for the correct evaluation of public projects and for conducting reviews of public expenditure. Estimates of the MCF for different taxes also provide a guide for tax reform by revealing which taxes cause the greatest welfare loss. The Marginal Cost of Public Funds explains the theory behind the MCF, details particular features of the MCF for a range of tax instruments, and most importantly shows how the theory is applied. The book is highly recommended as a text for students seeking an accessible presentation of the theory, and as a manual for applied economists who wish to ensure the employment of best-practice in project evaluation.

  • Dahlby's excellent new book will be very useful to all professional public finance economists, as well as graduate students and advanced seniors studying public finance. The marginal cost of public funds is central for understanding issues of tax and deficit policy, as well as benefit cost analysis, and Dahlby, an expert on the subject, has written a book that is clear, comprehensively researched, and important.

  • The marginal cost of public funds is a central and unifying concept for tax analysis, and Bev Dahlby's important new book provides the first comprehensive treatment of the topic. It carefully lays out the theoretical foundation of the concept, and then illustrates its policy relevance with a series of fascinating real-world applications in both developed and developing countries.
