The Labor Market And Business Cycle Theories

Interest in business cycles has had its 'ups and downs'. After a period of almost steady state growth and of economic tranquility, when the business cycle seemed to be obsolete, the turbulence of the 70s and 80s has contributedto a renewed interest in the topic. Important analytical and methodological innovations have also favored the present abundance of contributions. Four innovations are of particular importance: i. microfoundations ii. nonlinearities iii. stochastic variables iv. real aspects. Both Classical macroeconomics and new-Keynesian approaches seem to share these characteristics, which apply both to endogenous and exogenous explanations of the cycle. The distance separating the newer literature from its forebears seems vast. Previously, cycle theory was characterized by a macro approach and utilized nonlinearities either through piecewise 'linear models or with the aid of Classical theorems in the field of dynamic systems. To consider and to compare the old and the new literature on business cycles is one of the goals of this book. To narrow the distance separating them is another goal of this research. We do not try to bridge it, but rather to revisit the former tradition with new tools. Finally, a particular emphasis is put on the 'ceilings and floors' type of literature. One of us has written a D. Phil. thesis with Sir John Hicks, and both have worked with H. P. Minsky. Hicks, along with Goodwin, introdu. ced the concept of ceilings and floors into business cycle analysis, and Minsky made important contributions to the area.

Labor Markets and Business Cycles integrates search and matching theory with the neoclassical growth model to better understand labor market outcomes. Robert Shimer shows analytically and quantitatively that rigid wages are important for explaining the volatile behavior of the unemployment rate in business cycles. The book focuses on the labor wedge that arises when the marginal rate of substitution between consumption and leisure does not equal the marginal product of labor. According to competitive models of the labor market, the labor wedge should be constant and equal to the labor income tax rate. But in U.S. data, the wedge is strongly countercyclical, making it seem as if recessions are periods when workers are dissuaded from working and firms are dissuaded from hiring because of an increase in the labor income tax rate. When job searches are time consuming and wages are flexible, search frictions--the cost of a job search--act like labor adjustment costs, further exacerbating inconsistencies between the competitive model and data. The book shows that wage rigidities can reconcile the search model with the data, providing a quantitatively more accurate depiction of labor markets, consumption, and investment dynamics. Developing detailed search and matching models, Labor Markets and Business Cycles will be the main reference for those interested in the intersection of labor market dynamics and business cycle research.

The initial purposes of this book were to update and extend the discussion and the results presented ill our previous book, The Labor Market and Business Cycle Theories. Our 1990 article, which appeared in The Journal of Economic Behavior and Organization, represented a first step in this direction. The consequences of this effort have materialized in a number of new chapters that has led de facto to a new book, in which the surviving parts have been largely revised. The 1989 book was too mathematically oriented for many Keynesians and post Keynesians to be fully appreciated and insufficiently microfounded for both new classicals and new-Keynesians to be warmly accepted, yet we received positive and encouraging comments, and it was sold out very quickly. It was an attempt to dis cuss dynamics in Keynesian terms, based on a double assumption that maintains its validity-that both economic facts and analytical and methodological innova tions had contributed to a renewed interest in business cycles, which over time has had its "ups and downs." Since then, many more articles and books have appeared, stressing in particular the role of microfoundations and of nonlinearities in shaping business cycle theory.

In the l93Os, Dunlop and Tarshis observed that the correlation between hours and wages is close to zero. This classic observation has become a litmus test by which macroeconomic models are judged. Existing real business cycle models fail this test dramatically. Based on this result, we argue that technology shocks cannot be the sole impulse driving post-war U.S. business cycles. We modify prototypical real business cycle models by allowing government spending shocks to influence labor market dynamics in a way suggested by Aschauer (1985), Barro (1981, 1987) and Kormendi (1983), This modification can, in principle, bring the models into closer conformity with the data. While the empirical performance of the models is significantly improved, they still fail to account for the Dunlop-Tarshis observation. Accounting for that observation will require further advances in model development. Consequently, we conclude that theory is behind, not ahead of, business cycle measurement.

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.

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.

Victor Zarnowitz has long been a leader in the study of business cycles, growth, inflation, and forecasting. These papers represent a carefully integrated and up-to-date study of business cycles, reexamining some of his earlier research as well as addressing recent developments in the literature and in history. In part one, Zarnowitz reviews with characteristic insight various theories of the business cycle, including Keynesian and monetary theories as well as more recent rational expectations and real business cycle theories. In doing so, he examines how the business cycle may have changed as the size of government, the exercise of fiscal and monetary policies, the openness of the economy to international forces, and the industrial structure have evolved over time. Emphasizing important research from the 1980s, Zarnowitz discusses in part two various measures of the trends and cycles in economic activity, including output, prices, inventories, investment in residential and nonresidential structures, equipment, and other economic variables. Here the author explores the duration and severity of U.S. business cycles over more than 150 years, and evaluates the ability of macro models to simulate past behavior of the economy. In part three the performance of leading, coincident, and lagging indicators is described and assessed and evidence is presented on the value of their composite measures. Finally, part four offers an analysis of the degree of success of large commercial forecasting firms and of many individual economists in predicting the course of inflation, real growth, unemployment, interest rates, and other key economic variables. Business Cycles is a timely study, certain tobecome a basic reference for professional forecasters and economists in government, academia, and the business community.

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
