Macroeconomics would not be what it is today without Edmund Phelps. This book assembles the field's leading figures to highlight the continuing influence of his ideas from the past four decades. Addressing the most important current debates in macroeconomic theory, it focuses on the rates at which new technologies arise and information about markets is dispersed, information imperfections, and the heterogeneity of beliefs as determinants of an economy's performance. The contributions, which represent a breadth of contemporary theoretical approaches, cover topics including the real effects of monetary disturbances, difficulties in expectations formation, structural factors in unemployment, and sources of technical progress. Based on an October 2001 conference honoring Phelps, this incomparable volume provides the most comprehensive and authoritative account in years of the present state of macroeconomics while also pointing to its future. The fifteen chapters are by the editors and by Daron Acemoglu, Jess Benhabib, Guillermo A. Calvo, Oya Celasun, Michael D. Goldberg, Bruce Greenwald, James J. Heckman, Bart Hobijn, Peter Howitt, Hehui Jin, Charles I. Jones, Michael Kumhof, Mordecai Kurz, David Laibson, Lars Ljungqvist, N. Gregory Mankiw, Dale T. Mortensen, Maurizio Motolese, Stephen Nickell, Luca Nunziata, Wolfgang Ochel, Christopher A. Pissarides, Glenda Quintini, Ricardo Reis, Andrea Repetto, Thomas J. Sargent, Jeremy Tobacman, and Gianluca Violante. Commenting are Olivier J. Blanchard, Jean-Paul Fitoussi, Mark Gertler, Robert E. Hall, Robert E. Lucas, Jr., David H. Papell, Robert A. Pollak, Robert M. Solow, Nancy L. Stokey, and Lars E. O. Svensson. Also included are reflections by Phelps, a preface by Paul A. Samuelson, and the editors' introduction.

Assembling some of the leading figures in the field of macroeconomics, this text highlights the continuing influence of the ideas of Edmund Phelps since the early 1960s. The contributions address many of the most important current areas of macroeconomic research in 2003.

Posing a major challenge to economic orthodoxy, Imperfect Knowledge Economics asserts that exact models of purposeful human behavior are beyond the reach of economic analysis. Roman Frydman and Michael Goldberg argue that the longstanding empirical failures of conventional economic models stem from their futile efforts to make exact predictions about the consequences of rational, self-interested behavior. Such predictions, based on mechanistic models of human behavior, disregard the importance of individual creativity and unforeseeable sociopolitical change. Scientific though these explanations may appear, they usually fail to predict how markets behave. And, the authors contend, recent behavioral models of the market are no less mechanistic than their conventional counterparts: they aim to generate exact predictions of "irrational" human behavior. Frydman and Goldberg offer a long-overdue response to the shortcomings of conventional economic models. Drawing attention to the inherent limits of economists' knowledge, they introduce a new approach to economic analysis: Imperfect Knowledge Economics (IKE). IKE rejects exact quantitative predictions of individual decisions and market outcomes in favor of mathematical models that generate only qualitative predictions of economic change. Using the foreign exchange market as a testing ground for IKE, this book sheds new light on exchange-rate and risk-premium movements, which have confounded conventional models for decades. Offering a fresh way to think about markets and representing a potential turning point in economics, Imperfect Knowledge Economics will be essential reading for economists, policymakers, and professional investors.

This work provides up-to-date discussions of recent developments in modern macroeconomics; it also features interviews with leading economists that aim to shed new light on the major intellectual and policy issues of the 1990s.

An essential introduction to one of the most timely and important subjects in economics International Macroeconomics presents a rigorous and theoretically elegant treatment of real-world international macroeconomic problems, incorporating the latest economic research while maintaining a microfounded, optimizing, and dynamic general equilibrium approach. This one-of-a-kind textbook introduces a basic model and applies it to fundamental questions in international economics, including the determinants of the current account in small and large economies, processes of adjustment to shocks, the determinants of the real exchange rate, the role of fixed and flexible exchange rates in models with nominal rigidities, and interactions between monetary and fiscal policy. The book confronts theoretical predictions using actual data, highlighting both the power and limits of given theories and encouraging critical thinking. Provides a rigorous and elegant treatment of fundamental questions in international macroeconomicsBrings undergraduate and master’s instruction in line with modern economic researchFollows a microfounded, optimizing, and dynamic general equilibrium approachAddresses fundamental questions in international economics, such as the role of capital controls in the presence of financial frictions and balance-of-payments crisesUses real-world data to test the predictions of theoretical modelsFeatures a wealth of exercises at the end of each chapter that challenge students to hone their theoretical skills and scrutinize the empirical relevance of modelsAccompanied by a website with lecture slides for every chapter

Using nothing more than undergraduate mathematical skills this book takes the reader from basic IS-LM style macro models to the state of the art literature on Dynamic Stochastic General Equilibrium. Dealing with all major topics it summarizes important approaches and provides a coherent angle on macroeconomic thought.

A powerful challenge to contemporary economics and a new agenda for global finance In the wake of the global financial crisis that began in 2007, faith in the rationality of markets has lost ground to a new faith in their irrationality. The problem, Roman Frydman and Michael Goldberg argue, is that both the rational and behavioral theories of the market rest on the same fatal assumption—that markets act mechanically and economic change is fully predictable. In Beyond Mechanical Markets, Frydman and Goldberg show how the failure to abandon this assumption hinders our understanding of how markets work, why price swings help allocate capital to worthy companies, and what role government can and can't play. The financial crisis, Frydman and Goldberg argue, was made more likely, if not inevitable, by contemporary economic theory, yet its core tenets remain unchanged today. In response, the authors show how imperfect knowledge economics, an approach they pioneered, provides a better understanding of markets and the financial crisis. Frydman and Goldberg deliver a withering critique of the widely accepted view that the boom in equity prices that ended in 2007 was a bubble fueled by herd psychology. They argue, instead, that price swings are driven by individuals' ever-imperfect interpretations of the significance of economic fundamentals for future prices and risk. Because swings are at the heart of a dynamic economy, reforms should aim only to curb their excesses. Showing why we are being dangerously led astray by thinking of markets as predictably rational or irrational, Beyond Mechanical Markets presents a powerful challenge to conventional economic wisdom that we can't afford to ignore.

A timely investigation of the potential economic effects, both realized and unrealized, of artificial intelligence within the United States healthcare system. In sweeping conversations about the impact of artificial intelligence on many sectors of the economy, healthcare has received relatively little attention. Yet it seems unlikely that an industry that represents nearly one-fifth of the economy could escape the efficiency and cost-driven disruptions of AI. The Economics of Artificial Intelligence: Health Care Challenges brings together contributions from health economists, physicians, philosophers, and scholars in law, public health, and machine learning to identify the primary barriers to entry of AI in the healthcare sector. Across original papers and in wide-ranging responses, the contributors analyze barriers of four types: incentives, management, data availability, and regulation. They also suggest that AI has the potential to improve outcomes and lower costs. Understanding both the benefits of and barriers to AI adoption is essential for designing policies that will affect the evolution of the healthcare system.

It is a little over seventy years since John Maynard Keynes produced his magnum opus, The General Theory of Employment, Interest, and Money. Keynes' staggering achievement has been to remain relevant to economics and other disciplines even today and this book reflects that with an examination on his influence on modern economics. Leading economists from a variety of backgrounds, including Ed Nell and Heinz Kurz have joined forces in this volume with internationally respected Japanese scholars to produce a strong collection of contributions to the debate on Keynes' monumental legacy. This book will be vital reading for historians of economic thought, economic methodologists as well as those economists with an interest in the overall development of their discipline.

Inflation is regarded by the many as a menace that damages business and can only make life worse for households. Keeping it low depends critically on ensuring that firms and workers expect it to be low. So expectations of inflation are a key influence on national economic welfare. This collection pulls together a galaxy of world experts (including Roy Batchelor, Richard Curtin and Staffan Linden) on inflation expectations to debate different aspects of the issues involved. The main focus of the volume is on likely inflation developments. A number of factors have led practitioners and academic observers of monetary policy to place increasing emphasis recently on inflation expectations. One is the spread of inflation targeting, invented in New Zealand over 15 years ago, but now encompassing many important economies including Brazil, Canada, Israel and Great Britain. Even more significantly, the European Central Bank, the Bank of Japan and the United States Federal Bank are the leading members of another group of monetary institutions all considering or implementing moves in the same direction. A second is the large reduction in actual inflation that has been observed in most countries over the past decade or so. These considerations underscore the critical – and largely underrecognized - importance of inflation expectations. They emphasize the importance of the issues, and the great need for a volume that offers a clear, systematic treatment of them. This book, under the steely editorship of Peter Sinclair, should prove very important for policy makers and monetary economists alike.
