Global aging will impose greater economic demands on the young and may entail dramatic consumption shortfalls for the old. Against this gloomy backdrop, many analysts hail the world's funded pension systems as a means to protect future retirement security. The monographs reviewed ask how funded pension plans might be restructured to better meet the policy challenges of global aging. Both show that the pension institution must be reformulated to better provide for both economic growth and demographic aging. Questions remain regarding how retirement policy can better integrate intergenerational adequacy and incentive considerations.

This article reviews the memoirs of János Kornai. The famous Hungarian economist describes his life experiences and the concurrent history of Hungary. More importantly, he leads us through his intellectual evolution, explaining how his thinking evolved, how it was influenced by events, how one research question led to another. This brings alive the intellectual and historical developments that led to Kornai's work on socialist incentives, on the theory of planning, on the economics of shortage, and on the transition from socialism to capitalism. The book takes us on a journey that encompasses large elements of the history of economic thought in the second half of the twentieth century, as well as the history of Central Europe.

David Colander's update/reworking of his 1987 volume draws conclusions about graduate study in economics from interviews with students in selected leading U.S. programs. Although not formally statistical, the interviews support the conclusion that most of the core of graduate instruction (except macro) is handled very well. Colander's concern about the lack of attention to training teachers is well founded. His conclusion that fewer idiots savants are being trained than in the 1980s is overly optimistic, and his worry about stresses that graduate students express is misplaced.

America Works is a splendid book and Richard Freeman is to be congratulated on producing a work that sets out what is right and what is wrong with the U.S. labor market while being a joy to read. While I am generally sympathetic to both the analysis and the conclusions, there are a number of points of disagreement that I highlight in this review. In particular, I would add to his policy recommendations by taking a gamble and enacting a law that entitled all employees in the United States to four weeks paid holiday per year in addition to public holidays. This may transform summertime in the United States.

Ray Fair's Estimating How the Macroeconomy Works is the latest in a series of books by Fair that build, estimate, and apply his macroeconometric model to study the U.S. economy. In this book, Fair updates the model to incorporate the most recent data and uses it to analyze several important empirical questions, such as whether the U.S. economy moved into a new age of high productivity in the last half of the 1990s and the dynamics of prices, output, and unemployment. This review places his work in the context of the historical evolution of aggregate econometric models, compares it with the current developments in the estimation of dynamic stochastic general equilibrium models, and discusses some salient aspects of Fair's contributions.

This book collects essays, most of which were published earlier, into an advertisement for real business cycle (RBC) analysis. Half of the essays discuss the Great Depression; half discuss events of the 1980s and 1990s. They all use the general equilibrium model of economic growth to analyze short-run fluctuations in the rate of economic growth of various countries. I find that the use of closed economy models without frictions is not useful for the analysis of short-run variations in the rate of economic growth. Almost all of these essays end by claiming that variations in the rate of GDP growth were due to changes in the rate of total factor productivity (TFP) growth. They do not provide any explanation for fluctuations in the rate of TFP growth, leaving the reader no closer to understanding these periods of depression and slow growth. I discuss in turn the essays on the Great Depression, the essays on more recent fluctuations, and the definition of “great depressions” used in this volume.

The role of improved schooling, a central part of most development strategies, has become controversial because expansion of school attainment has not guaranteed improved economic conditions. This paper reviews the role of cognitive skills in promoting economic well-being, with a particular focus on the role of school quality and quantity. It concludes that there is strong evidence that the cognitive skills of the population—rather than mere school attainment—are powerfully related to individual earnings, to the distribution of income, and to economic growth. New empirical results show the importance of both minimal and high level skills, the complementarity of skills and the quality of economic institutions, and the robustness of the relationship between skills and growth. International comparisons incorporating expanded data on cognitive skills reveal much larger skill deficits in developing countries than generally derived from just school enrollment and attainment. The magnitude of change needed makes clear that closing the economic gap with developed countries will require major structural changes in schooling institutions.

The economics of information has identified an important role for government to correct situations where competition is not sufficient to reveal valuable information to consumers. Archon Fung, Mary Graham, and David Weil's Full Disclosure: The Perils and Promise of Transparency provides a thorough discussion of government-mandated disclosure policies. I use their book to frame an empirical assessment of whether these—and other information policies—have significantly reduced the costs to consumers created by imperfect information. My conclusion, which calls for more research, is that government information policies have amounted to weak solutions in search of a problem.
