The Marginal Cost of Public Funds
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.

"Dahlby's excellent new book will be very useful to all professional publicfinance economists, as well as graduate students and advanced seniorsstudying public finance. The marginal cost of public funds is central forunderstanding issues of tax and deficit policy, as well as benefit costanalysis, and Dahlby, an expert on the subject, has written a book that isclear, comprehensively researched, and important."

"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 important, 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."
