These essays, though formally independent, nevertheless constitute a whole, each one preparing the way for the succeeding chapter.

In the early 1980s, rational expectations and new classical economics dominated macroeconomic theory. This essay evolved from theauthors' profound disagreement with that trend. It demonstrates notonly how the new classical view got macroeconomics wrong, but also howto go about doing macroeconomics the right way.

This book consists of the major work of Professor Ping Chen, a pioneer in studying economic chaos and economic complexity. They are selected from works completed since 1987, integrating different insights from Marx, Marshall, Schumpeter and Keynes.

The worldwide Great Depression of the 1930s was a watershed for both economic thought and economic policymaking. It led to the belief that market economies are inherently unstable and to the revolutionary work of John Maynard Keynes. Its impact on popular economic wisdom is still apparent today. Great Depressions of the Twentieth Century, which uses a common framework to study sixteen depressions from the interwar period in Europe and America, as well as from more recent times in Japan and Latin America, challenges the Keynesian theory of depressions. It develops and uses a methodology for studying depressions that relies on growth accounting and the general equilibrium growth model. Different chapters in this book analyze the depressions in Canada, France, Germany, Italy, the United Kingdom, and the United States in the 1930s, the depressions in Argentina, Brazil, Chile, and Mexico in the 1980s, and recent depressions in Argentina, Finland, Japan, New Zealand, and Switzerland. Besides the editors themselves, the contributors are Pedro Amaral, Paul Beaudry, Raphael Bergoeing, Mirta Bugarin, Harold Cole, Juan Carlos Conesa, Mario Crucini, Roberto Ellery, Victor Gomes, Jonas Fisher, Fumio Hayashi, Andreas Hornstein, James Kahn, Patrick Kehoe, Finn Kydland, James MacGee, Lee Ohanian, Fabrizio Perri, Franck Portier, Vincenzo Quadrini, Kim Ruhl, Raimundo Soto, Arilton Teixeira, and Carlos Zarazaga.

The main purpose of Lectures on Macroeconomics is to characterize and explain fluctuations in output, unemployment and movement in prices. Lectures on Macroeconomics provides the first comprehensive description and evaluation of macroeconomic theory in many years. While the authors' perspective is broad, they clearly state their assessment of what is important and what is not as they present the essence of macroeconomic theory today.The main purpose of Lectures on Macroeconomics is to characterize and explain fluctuations in output, unemployment and movement in prices. The most important fact of modern economic history is persistent long term growth, but as the book makes clear, this growth is far from steady. The authors analyze and explore these fluctuations. Topics include consumption and investment; the Overlapping Generations Model; money; multiple equilibria, bubbles, and stability; the role of nominal rigidities; competitive equilibrium business cycles, nominal rigidities and economic fluctuations, goods, labor and credit markets; and monetary and fiscal policy issues. Each of chapters 2 through 9 discusses models appropriate to the topic. Chapter 10 then draws on the previous chapters, asks which models are the workhorses of macroeconomics, and sets the models out in convenient form. A concluding chapter analyzes the goals of economic policy, monetary policy, fiscal policy, and dynamic inconsistency. Written as a text for graduate students with some background in macroeconomics, statistics, and econometrics, Lectures on Macroeconomics also presents topics in a self contained way that makes it a suitable reference for professional economists.

This is a collection of essays on the development of modern macroeconomics. It reflects the profound and controversial changes that the subject has undergone in the period 1974 to 1999. Each of the eight essays focuses on an important issue relating to those changes.

The recent financial crisis and the difficulty of using mainstream macroeconomic models to accurately monitor and assess systemic risk have stimulated new analyses of how we measure economic activity and the development of more sophisticated models in which the financial sector plays a greater role. Markus Brunnermeier and Arvind Krishnamurthy have assembled contributions from leading academic researchers, central bankers, and other financial-market experts to explore the possibilities for advancing macroeconomic modeling in order to achieve more accurate economic measurement. Essays in this volume focus on the development of models capable of highlighting the vulnerabilities that leave the economy susceptible to adverse feedback loops and liquidity spirals. While these types of vulnerabilities have often been identified, they have not been consistently measured. In a financial world of increasing complexity and uncertainty, this volume is an invaluable resource for policymakers working to improve current measurement systems and for academics concerned with conceptualizing effective measurement.
