Growing out of a conference on Expectations Formation and Economic Disequilibrium held in New York City in 1981, the papers in this volume provide a complex view of market processes in which individual rationality is no guarantee of convergence to the 'correct' model and the equilibrium coordination of agents' plans. They reject the 'optimality' argument for the rational expectations hypothesis, opening the door to other hypotheses of optimal expectations of agents in the decentralized market economy.

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.

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.

This book originated from a 2010 conference marking the fortieth anniversary of the publication of the landmark "Phelps volume," Microeconomic Foundations of Employment and Inflation Theory, a book that is often credited with pioneering the currently dominant approach to macroeconomic analysis. However, in their provocative introductory essay, Roman Frydman and Edmund Phelps argue that the vast majority of macroeconomic and finance models developed over the last four decades derailed, rather than built on, the Phelps volume's "microfoundations" approach. Whereas the contributors to the 1970 volume recognized the fundamental importance of according market participants' expectations an autonomous role, contemporary models rely on the rational expectations hypothesis (REH), which rules out such a role by design. The financial crisis that began in 2007, preceded by a spectacular boom and bust in asset prices that REH models implied could never happen, has spurred a quest for fresh approaches to macroeconomic analysis.While the alternatives to REH presented in Rethinking Expectations differ from the approach taken in the original Phelps volume, they are notable for returning to its major theme: understanding aggregate outcomes requires according expectations an autonomous role. In the introductory essay, Frydman and Phelps interpret the various efforts to reconstruct the field--some of which promise to chart its direction for decades to come. The contributors include Philippe Aghion, Sheila Dow, George W. Evans, Roger E. A. Farmer, Roman Frydman, Michael D. Goldberg, Roger Guesnerie, Seppo Honkapohja, Katarina Juselius, Enisse Kharroubi, Blake LeBaron, Edmund S. Phelps, John B. Taylor, Michael Woodford, and Gylfi Zoega.

In this work, comprehensive comparative information on five Central European countries has been collected by teams of researchers from both within the region and from the West. Following an introduction to the economic environment in each country, it provides an overview of the privatization process, including an account of the legal framework of ownership, institutions for state regulation, an overview of privatization programmes and the initial transformation of enterprises. A key feature of the book is the authors' access to hitherto unavailable information and their ability to present a vast amount of material in an easily available format. Aimed at policy makers and business people, the work should provide a strong foundation for future research.

In Eastern Europe privatization is now a mass phenomenon. The authors propose a model of it by means of an illustration from the example of Poland, which envisages the free provision of shares in formerly public undertakings to employees and consumers, and the provision of corporate finance from foreign intermediaries. One danger that emerges is that of bureaucratization. On the broader canvas, mass privatization implies the reform of the whole system, the creation of a suitable economic infrastructure for a market economy and the institutions of corporate governance. The authors point out the need for a delicate balance between evolution - which may be too slow - and design - which brings the risk of more government involvement than it is able to manage. A chapter originating as a European Bank working paper explores the banking implications of setting up a totally new financial sector with interlocking classes of assets. The economic effects merge into politics as the role of the state is investigated. Teachers and graduate students of public/private sector economies, East European affairs; advisers to bankers or commercial companies with Eastern European interests.

The authors of this treatise attempt to provide a deeper understanding of the economic and political transformations now taking place in Poland, Hungary and the Czech Republic. They build up a detailed picture of the privatization process in the retail trade, catering and more general services. Not only are these sectors strongly relevant to consumers in these countries, but they also offer attractive possibilities for property ownership on a mass scale, as well as for the fostering of the small enterprises and entrepreneurial spirit that will be so important in the future.

The studies in this two-volume work shed new light on the range and viability of the emerging corporate governance institutions in the transitional economies of Central Europe. Regional specialists and experts on corporate governance in advanced economies examine the emerging forms of ownership and complementary monitoring institutions in leading transition companies.
