Peter Isard's recent book (Globalization and the International Financial System: What's Wrong and What Can be Done?, Cambridge University Press, 2005) provides a thoughtful and balanced review of the scholarly literature on the past operation and potential reform of the international monetary and financial system. The author's approach, from which much can be learned, is to draw lessons from the history of exchange rates and capital flows and, especially, from the financial crises of the 1990s. But this retrospective focus is also revealing of what is new and different about our current international monetary and financial environment and in the ongoing debate surrounding the future of its steward, the International Monetary Fund.

Editor's Note The Journal of Economic Literature (JEL) regularly reviews books of interest to the economics profession. The Economic Report of the President (ERP) falls under that purview. I have asked a handful of very prominent economists to review the 2006 ERP. Reviewers were chosen to reflect expertise on what I guessed would be key issues. The ERP in principle should provide an accurate assessment of the consensus professional views of economists on any given issue, based on the research to date. Reviewers were asked to evaluate whether the discussion in the ERP in fact accurately summarizes what we as economists know? Reviewers were given free rein over what material they would review in the ERP but were urged to focus on their areas of particular expertise. In the reviews that follow, Martin Feldstein reviews the overview chapter as well as topics relating to macroeconomics. Alan Auerbach reviews the ERP's discussion of tax-related issues, while Ken Rogoff reviews the ERP's discussion of international economic topics. Rebecca Blank writes on labor market issues in the ERP, and Michael Katz reviews the ERP's discussion of health care issues. Many thanks to the reviewers for the quick turnaround.

This essay reviews and criticizes Vermeij's Nature: An Economic History and places it in the context of evolutionary economics. Vermeij presents a natural history written in what he considers economic terms and argues that biologists should know more about economics. While the exchanges between economics and biology can sometimes be hazardous and misleading, quite a bit could be learned by economists from reading this book.

Following George Stigler (1964), many economists assume that incentive problems undermine attempts b firms to collude to raise prices and restrict output. But the potential profits from collusion can create a powerful incentive as well. Theory cannot tell us, a priori, which effect will dominate: whether or when cartels succeed is thus an empirical question. We examine a wide variety of empirical studies of cartels to answer the following questions: (1) Can cartels succeed? (2) If so, for how long? (3) What impact do cartels have? (4) What causes cartels to break up? We conclude that many cartels do survive, and that the distribution of duration is bimodal. While the average duration of cartels across a range of studies is about five years, many cartels break up very quickly (i.e., in less than a year). But there are many others that last between five and ten years, and some that last decades. Limited evidence suggests that cartels are able to increase prices and profits, to varying degrees. Cartels can also affect other non-price variables, including advertising, innovation, investment, barriers to entry, and concentration. Cartels break up occasionally because of cheating or lack of effective monitoring, but the biggest challenges cartels face are entry and adjustment of the collusive agreement in response to changing economic conditions. Cartels that develop organizational structures that allow them the flexibility to respond to these changing conditions are more likely to survive. Price wars that erupt are often the result of bargaining issues that arise in such circumstances. Sophisticated cartel organizations are also able to develop multipronged strategies to monitor one another to deter cheating and a variety of interventions to increase barriers to entry.

Steven Shavell's Foundations of Economic Analysis of Law (Harvard University Press, 2004) is a major theoretical contribution to “law and economics,” the applied field of economics that studies the economic properties and consequences of legal doctrines and institutions. It is a field of immense practical importance, but unfamiliar to many economists—a situation that Shavell's book bids fair to rectify. This review essay situates Shavell's book in the history of economic scholarship about law and uses the book as a springboard for speculation about new directions in that scholarship.

Stanley Fischer was deputy managing director of the IMF from 1994 to 2001 and, perhaps more than any other individual, he personifies the international “rapid response” to financial crises in the 1990s. This book is a collection of essays written during his tenure at the IMF; taken together, the essays represent the strongest and most logical defense of IMF initiatives in the 1990s in print. My review essay comprises six parts. In parts 2 through 4, I provide an overview of Fischer's arguments in three central areas of contention: stabilization policy, the impact of IMF programs on poverty, and the IMF's anticipation of and response to international financial crisis. I then compare Fischer's arguments to those raised by the IMF's critics during that period. The controversial issues of these parts can be resolved only through empirical investigation but, on the issues of greatest importance from the financial crises of the 1990s, both Fischer and the IMF's critics make logically consistent arguments with little empirical support. In part 5, I review the recent empirical literature to illuminate what evidence has been found in support of—or counter to—the assertions of Fischer and the IMF's critics. Part 6 provides conclusions and suggestions for follow-on empirical research.

Saving Capitalism from the Capitalists is an ambitious probe into capitalism's past, present, and future. Whereas Joseph A. Schumpeter viewed capitalism as doomed because it was losing its political and social supports, Rajan and Zingales see it more as threatened from within by established or “incumbent” industrialists and financiers who become enemies of free markets. The authors contend that free financial markets foster economic progress while undermining the ability of incumbents to have their way. Rajan and Zingales may overstate the significance of “the great reversal” of financial development in the middle decades of the twentieth century, and their evidence and interpretations are sometimes flawed. Nonetheless, they make a strong case for the fundamental importance of financial development for economic modernization and their warnings about the antimarket tendencies of incumbents are well worth pondering.
