This 2004 textbook explores how markets operate and governments' roles in addressing market failures.

A rigorous, self-contained textbook covering all the central topics in public economics.

This text by one of Europe's leading economists covers a wide variety of public economics issues with great clarity and precision, illustrating them with a wealth of carefully-chosen examples and problems. Starting from theories of general equilibrium analysis, Laffont considers issues of market failure, collective decisionmaking, and distributional equity. He analyzes the important informational and motivational problems involved in planning solutions for market failures, and provides a rigorous justification for the theoretical foundations of public economics. Topics include the theories of externalities, public goods, collective choice, consumer surplus, cost-benefit analysis and/or theory of the second best, incomplete markets, and nonconvexities. For each Laffont begins with the classical foundations, moves on to consider the topic within a simple model of the economy, and concludes by integrating results from recent journal articles into this simple framework. In this way students are led to understand the classical tradition in the context of modern general equilibrium theory. The book concludes with eight problems with solutions, each interesting and rich enough to be considered a case study, and nine exercises without solutions; together they provide an excellent review of material covered in the text. The basic approach in each problem is to set up a general equilibrium model, discover the market failure by calculating the unfettered equilibrium, and develop an explicit planning solution. Jean-Jacques Laffont is Professor of Economics at the University of Social Sciences at Toulouse. Fundamentals of Economics may be used in either an advanced graduate-level course in public economics or in conjunction with a second volume forthcoming by the same author in a course in advanced microeconomics.

To better understand the role and importance of government, it is important to try to comprehend all aspects of public economics and finance. This book covers many of these aspects and presents a core thesis that government is a fundamental instrument of the social welfare of communities. It provides the reader with a comprehensive overview of new era states, and answers the question, does the new era require new government policies? Over five chapters, authors from a variety of disciplines and methodological approaches cover topics such as welfare states and social policies, borrowing in the context of public debt theory, and new budgetary approaches. This volume is a valuable contribution to the field and will be appreciated by the global community of scholars.

A new edition of a comprehensive text, updated throughout, with new material on behavioral economics, international taxation, cost-benefit analysis, and the economics of climate policy. Public economics studies how government taxing and spending activities affect the economy—economic efficiency and the distribution of income and wealth. This comprehensive text on public economics covers the core topics of market failure and taxation as well as recent developments in both policy and the academic literature. It is unique not only in its broad scope but in its balance between public finance and public choice and its combination of theory and relevant empirical evidence. The book covers the theory and methodology of public economics; presents a historical and theoretical overview of the public sector; and discusses such topics as departures from efficiency (including imperfect competition and asymmetric information), issues in political economy, equity, taxation, fiscal federalism, and tax competition among independent jurisdictions. Suggestions for further reading, from classic papers to recent research, appear in each chapter, as do exercises. The mathematics has been kept to a minimum without sacrificing intellectual rigor; the book remains analytical rather than discursive. This second edition has been thoroughly updated throughout. It offers new chapters on behavioral economics, limits to redistribution, international taxation, cost-benefit analysis, and the economics of climate policy. Additional exercises have been added and many sections revised in response to advice from readers of the first edition.

Today, the most pressing challenges for public economics are of macroeconomic nature: pensions, debt, income distribution, and fiscal sustainability. All these problems are compounded by the phenomenon of demographic transition and aging. This graduate textbook addresses these issues with the help of state-of-the-art macroeconomic tools that are based on a sound microfoundation and rooted in empirical evidence. Different from the standard partial-equilibrium analysis in traditional textbooks on public economics, the concept of general equilibrium helps to account for compensating or amplifying side-effects of economic policy.
