It is argued that taxation causes three kinds of deadweight losses and two types of direct costs. The deadweight losses arise from substitution, evasion, and avoidance activities while the direct costs are administrative and compliance costs. Some of these social costs tend to be discontinuous and/or nonconvex. Because most models of taxation ignore some components of the social costs of taxation, their conclusions cannot be of a general nature. An alternative approach to policy evaluation is to rely on a marginal efficiency cost of funds rule which can indicate appropriate directions of reforms. The paper discusses its merits, applicability, and limitations, as well as its relationship to other concepts.

The book provides a hands-on introduction to computable general equilibrium (CGE) models, written at an accessible, undergraduate level.

Based on their work in the application of principal-agent theory to questions of regulation, Laffont and Tirole develop a synthetic approach to this field, focusing on the regulation of natural monopolies such as military contractors, utility companies and transportation authorities.

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.

This paper identifies policy tools that could be used for fiscal consolidation in advanced and emerging economies in the years ahead. The consolidation strategy, particularly in advanced countries, should aim to stabilize age-related spending in relation to GDP, reduce non-age-related expenditure ratios, and increase revenues. Bold reforms are needed to offset projected increases in age-related spending, particularly health care. On the revenue side, measures could include improving tax compliance, for example through better international cooperation, as well as increasing the yield from VAT by eliminating exemptions and reduced rates, further developing property taxes, and increasing excise rates within the range of rates already applicable in comparable countries.

When A Revision of Demand Theory was first published in 1956, the late Harry Johnson described it as "elegant in the extreme, probably the last word there is to be said on this aspect of demand theory." This landmark work by Nobel Prize winner J.R. Hicks is now available again.
