The new classical approach to macroeconomics, which assumes that people gather and use economic information efficiently, has been the most important theoretical advance since the Keynesian revolution of the 1930s. This book surveys the major contributions of the "second generation" of proponents of the new classical approach, emphasizing real business cycle theories and applying them to a variety of phenomena. The chapters include expositions of growth theory, real models of business fluctuations, the informational role of prices, consumption, fiscal policy, rules versus discretion in monetary policy, time consistency and policy, and monetary models. Although the chapters are aimed at advanced undergraduate- and graduate-level students, they will also be of interest to researchers who are looking for a compact and original exposition of the new classical macroeconomics.

In recent decades the American economy has experienced the worst peace-time inflation in its history and the highest unemployment rate since the Great Depression. These circumstances have prompted renewed interest in the concept of business cycles, which Joseph Schumpeter suggested are "like the beat of the heart, of the essence of the organism that displays them." In The American Business Cycle, some of the most prominent macroeconomics in the United States focuses on the questions, To what extent are business cycles propelled by external shocks? How have post-1946 cycles differed from earlier cycles? And, what are the major factors that contribute to business cycles? They extend their investigation in some areas as far back as 1875 to afford a deeper understanding of both economic history and the most recent economic fluctuations. Seven papers address specific aspects of economic activity: consumption, investment, inventory change, fiscal policy, monetary behavior, open economy, and the labor market. Five papers focus on aggregate economic activity. In a number of cases, the papers present findings that challenge widely accepted models and assumptions. In addition to its substantive findings, The American Business Cycle includes an appendix containing both the first published history of the NBER business-cycle dating chronology and many previously unpublished historical data series.

An academic colleague has called Lucas "the dominant figure in Americanmacroeconomics." And another refers to this group of 14 essays, nearly all of which were firstpublished during the 1970s, as the most influential contribution to macroeconomics in thatdecade.

In the years following its publication, F. A. Hayek's pioneering work on business cycles was regarded as an important challenge to what was later known as Keynesian macroeconomics. Today, as debates rage on over the monetary origins of the current economic and financial crisis, economists are once again paying heed to Hayek's thoughts on the repercussions of excessive central bank interventions. The latest editions in Routledge's ongoing series The Collected Works of F. A. Hayek, these volumes bring together Hayek's work on what causes periods of boom and bust in the economy. Moving away from the classical emphasis on equilibrium, Hayek demonstrates that business cycles are generated by the adaptation of the structure of production to changes in relative demand. Thus, when central banks artificially lower interest rates, the result is a misallocation of capital and the creation of asset bubbles and additional instability. Business Cycles: Part I contains Hayek's two major monographs on the topic: Monetary Theory and the Trade Cycle and Prices and Production. Reproducing the text of the original 1933 translation of the former, this edition also draws on the original German, as well as more recent translations. For Prices and Production, a variorum edition is presented, incorporating the 1931 first edition and its 1935 revision. Business Cycles: Part II assembles a series of Hayek's shorter papers on the topic, ranging from the 1920s to 1981. In addition to bringing together Hayek's work on the evolution of business cycles, the two volumes of Business Cycles also include extensive introductions by Hansjoerg Klausinger, placing the writings in intellectual context, including their reception and the theoretical debates to which they contributed, and providing background on the evolution of Hayek's thought.

Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.

This volume presents the most complete collection available of the work of Victor Zarnowitz, a leader in the study of business cycles, growth, inflation, and forecasting.. With characteristic insight, Zarnowitz examines theories of the business cycle, including Keynesian and monetary theories and more recent rational expectation and real business cycle theories. He also measures trends and cycles in economic activity; evaluates the performance of leading indicators and their composite measures; surveys forecasting tools and performance of business and academic economists; discusses historical changes in the nature and sources of business cycles; and analyzes how successfully forecasting firms and economists predict such key economic variables as interest rates and inflation.
