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.

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.

During our lifetime we experience any number of business cycle crises which undermine our confidence and lead many to their ruin. We also experience the ‘happy days’ when our faith in the future becomes almost limitless, and when we forget that tides always turn again. So how can we better understand and predict these cycles? To answer these questions Lars Tvede takes us through a story that moves back in time to the Scottish gambler and financial genius, John Law, and then on to the distracted Adam Smith, the stockbroker Ricardo, the investment banker Thornton, the extrovert Schumpeter, the speculator Gould and many others to trace the theory and reality of business cycles, as it has evolved over 300 years. Gradually we reach the computer jugglers of the modern day who, with giant networks of equations, try to solve the same questions that have attracted the attention of classical economists throughout the centuries. Lars Tvede concludes this historical journey with a summary of what the core of the problem is and how modern understanding of business cycles can be used to forecast economic fluctuations. The final sections of the book provide detailed studies and explanations to of how stocks, bonds, hedge funds, private equity funds, gold, diamonds, exchange rates, real estate, commodities, art and collectibles, and numerous sub-sectors of some of these markets each behave over different categories of business cycles.

"Is the business cycle obsolete?" This often cited title of a book edited by Bronfenbren ner with the implicit affirmation of the question reflected the attitude of mainstream macroeconomics in the Sixties regarding the empirical relevance of cyclic motions of an economy. The successful income policies, theoretically grounded in Keynesian macroec onomics, seemed to have eased or even abolished the fluctuations in West,ern economies which motivated studies of many classical and neoclassical economists for more than 100 years. The reasoning behind the conviction that business cycles would increasingly become irrelevant was rather simple: if an economy fluctuates for whatever reason, then it is almost always possible to neutralize these cyclic motions by means of anti-cyclic demand policies. From the 1950's until the mid-Sixties business cycle theory had often been consid ered either as an appendix to growth theory or as an academic exercise in dynamical economics. The common business cycle models were essentially multiplier-accelerator models whose sensitive dependence on parameter values (in order to be called busi ness cycle models) suggested a rather improbable occurrence of continuing oscillations. The obvious success in compensating business cycles in those days prevented intensive concern with the occurrence of cycles. Rather, business cycle theory turned into sta bilization theory which investigated theoretical possibilities of stabilizing a fluctuating economy. Many macroeconomic textbooks appeared in the Sixties which consequently identified business cycle theory with inquiries on the possibilities to stabilize economies 2 Introduction by means of active fiscal or monetary policies.

Among the most revolutionary and productive areas of economic research over the last two decades, modern business cycle theory is finally made accessible to students and professionals in this rigorous, unified, introductory volume. This theory starts with the view that growth and fluctuations are not distinct phenomena to be studied separately--and that business cycles result from shocks (such as the availability of new technologies), which regularly affect most economies. The unifying theme of this book is the use of the neoclassical growth framework to study the economic fluctuations associated with the business cycle. Presenting recent advances in dynamic economic theory and computational methods--with emphasis on the construction of equilibrium paths for simple artificial economies--leading experts orient readers in the quantitative study of aggregate fluctuations and apply its concepts to key issues in macroeconomics and business cycle theory. This volume covers such issues as the aggregate labor market, the role of the household sector, the role of money, the behavior of asset markets, non-Walrasian economies, monopolistically competitive economies, international business cycles, and the design of economic policies. The contributors are David Backus, V. V. Chari, Lawrence Christiano, Thomas F. Cooley, Jean-Pierre Danthine, John Donaldson, Jeremy Greenwood, Gary D. Hansen, Patrick Kehoe, Finn Kydland, Edward C. Prescott, Richard Rogerson, Julio Rotemberg, Geert Rouwenhorst, José-Víctor Ríos-Rull, Michael Woodford, and Randall Wright.
