Business Cycle Dynamics

Business cycle theory has been one of the fastest growing fields in modern nonlinear economic dynamics. This book presents new mathematical methods for global analysis which have not previously been available in this easily accessible form. In addition it contains a presentation of full analyses of several models left open in the 1950s when the tools then available did not permit more systematic analysis.

As the 55th anniversary of the bank holiday of March 1933 approached, financial instability was a main topic in the financial press. Daily reports appeared of international debt crises, of the covert bankruptcy of deposit insurance, and of the near bankruptcy of one great financial institution after another. The great stock market crash of October 19 and 20, 1987, demonstrated that extreme instability can happen. It is generally asserted that the consequences of October 19th and 20th would have been disastrous if the Federal Reserve and Treasury interventions had not set things right. In 1933, financial markets in the United States and throughout the capitalist world collapsed. In the light of historical experience, the past 55 years are the anomaly. The papers collected in this volume come from various backgrounds and research paradigms. A common theme runs through these papers that makes the collection both interesting and important: The authors take seriously the obvious evidence that capitalist economies progress through time by lurching. Whether a particular study starts from household utility maximization or from the processes by which productive structures are reproduced and expanded, the authors are united in accepting the evidence that financial instability is a significant characteristic of modern capitalism.

This monograph is devoted to the analysis of the dynamics of business cycles and stabilization policies. The analysis is conducted in models of the AS-AD type, focusing on involuntary unemployment and capital accumulation. Major conclusions are the following. (1) Sectoral imbalances, once emphasized by such business-cycle theorists as K. Marx, A. Spiethoff, and F.A. Hayek, are rectified in finite time by competitive investment allocation, leaving aggregate variables as the main variables of business cycle dynamics. (2) The chronology of events during a cycle is established, which resolves the so-called real wage puzzle. (3) Owing to the crowding-out effect on investment, fiscal stabilization policies can destabilize the business cycle dynamics if implemented too intensively. (4) If coordinated properly, monetary stabilization policies can remove the destabilizing tendency of fiscal stabilization policies.

This is the most sophisticated and up-to-date econometric analysis of business cycles now available. Francis Diebold and Glenn Rudebusch have long been acknowledged as leading experts on business cycles. And here they present a highly integrative collection of their most important essays on the subject, along with a detailed introduction that draws together the book's principal themes and findings. Diebold and Rudebusch use the latest quantitative methods to address five principal questions about the measurement, modeling, and forecasting of business cycles. They ask whether business cycles have become more moderate in the postwar period, concluding that recessions have, in fact, been shorter and shallower. They consider whether economic expansions and contractions tend to die of "old age." Contrary to popular wisdom, they find little evidence that expansions become more fragile the longer they last, although they do find that contractions are increasingly likely to end as they age. The authors discuss the defining characteristics of business cycles, focusing on how economic variables move together and on the timing of the slow alternation between expansions and contractions. They explore the difficulties of distinguishing between long-term trends in the economy and cyclical fluctuations. And they examine how business cycles can be forecast, looking in particular at how to predict turning points in cycles, rather than merely the level of future economic activity. They show here that the index of leading economic indicators is a poor predictor of future economic activity, and consider what we can learn from other indicators, such as financial variables. Throughout, the authors make use of a variety of advanced econometric techniques, including nonparametric analysis, fractional integration, and regime-switching models. Business Cycles is crucial reading for policymakers, bankers, and business executives.

Originally published in 1942, this landmark volume makes available the entire business-cycle analysis of the Dutch economist, Jan Tinbergen, whose work in economic dynamics stimulated a new school of econometric research. The book explains what is typical and common in economic movements - the system of supply and demand schedules used to describe a market, certain technical relations, and 'balance equations'.

This introduction to modern business cycle theory uses a neoclassical growth framework to study the economic fluctuations associated with the business cycle. Presenting advances in dynamic economic theory and computational methods, it applies concepts to t
