What Prevents a Real Business Cycle Model from Matching the U.S. Data? Decomposing the Labor Wedge


Book Description

I carry out a business cycle accounting exercise (Chari, Kehoe and McGrattan, 2007) on the U.S. data measured in wage units (Farmer (2010)) for the entire postwar period. In contrast to a conventional approach, this approach preserves common medium-term business cycle fluctuations in GDP, its components and the unemployment rate. Additionally, it facilitates decomposition of the labor wedge into the labor supply and the labor demand wedges. Using this business cycle accounting methodology, I find that in the transformed data, most movements in GDP are accounted for by the labor supply wedge. Therefore, I reverse a key finding of the real business cycle literature which asserts that 70% or more of economic fluctuations can be explained by TFP shocks. In other words, the real business cycle model fits the data badly because the assumption that households are on their labor supply equation is flawed. This failure is masked by data that has been filtered with a conventional approach that removes fluctuations at medium frequencies. My findings are consistent with the literature on incomplete labor markets.




Technology Shocks and Aggregate Fluctuations


Book Description

Our answer: Not so well. We reached that conclusion after reviewing recent research on the role of technology as a source of economic fluctuations. The bulk of the evidence suggests a limited role for aggregate technology shocks, pointing instead to demand factors as the main force behind the strong positive comovement between output and labor input measures.




Modern Business Cycle Theory


Book Description

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.




Hysteresis and Business Cycles


Book Description

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.




Labor Markets and Business Cycles


Book Description

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.




Frontiers of Business Cycle Research


Book Description

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




Real Business Cycles


Book Description

Real Business Cycle theory combines the remains of monetarism with the new classical macroeconomics, and has become one of the dominant approaches within contemporary macroeconomics today. This volume presents: * the authoritative anthology in RBC. The work contains the major articles introducing and extending the theory as well as critical literature * an extensive introduction which contains an expository summary and critical evaluation of RBC theory * comprehensive coverage and balance between seminal papers and extensions; proponents and critics; and theory and empirics. Macroeconomics is a compulsory element in most economics courses, and this book will be an essential guide to one of its major theories.




Business Cycle Economics


Book Description

Presents the empirical data of business cycles and the theories that economists have developed to explain and prevent them, and considers case studies of recessions and depressions in the United States and internationally. Despite more than two centuries of debate, a definitive explanation of the causes of economic cycles still does not exist. Economists, politicians, and policymakers have argued many well-known theories as to why these peaks and slumps occur, and cyclical recessions and depressions continue in spite of the enormous intellectual reserves working to prevent them. This timely analysis presents a comprehensive overview of global economics, assessing older theories alongside of new ways of thinking to reveal the empirical methods needed to evaluate, forecast, and prevent future crises. Educator and economist Todd Knoop provides explanations of influential macroeconomic theories that have shaped modern economics, such as Keynesian economics, Neoclassical economics, Austrian economics, and New Keynesian economics. In addition, he considers case studies of specific recessions and depressions, beginning with the Great Depression through the East Asian crisis and Great Recession in Japan and culminating with a detailed examination of the European debt crisis and the 2008 global financial crisis. The work concludes with a look at the insights gained from these fiscal events as well as the major questions that still remain unanswered as a result of these crises.




Environmental and Energy Policy and the Economy


Book Description

This volume presents six new papers on environmental and energy economics and policy in the United States. Rebecca Davis, J. Scott Holladay, and Charles Sims analyze recent trends in and forecasts of coal-fired power plant retirements with and without new climate policy. Severin Borenstein and James Bushnell examine the efficiency of pricing for electricity, natural gas, and gasoline. James Archsmith, Erich Muehlegger, and David Rapson provide a prospective analysis of future pathways for electric vehicle adoption. Kenneth Gillingham considers the consequences of such pathways for the design of fuel vehicle economy standards. Frank Wolak investigates the long-term resource adequacy in wholesale electricity markets with significant intermittent renewables. Finally, Barbara Annicchiarico, Stefano Carattini, Carolyn Fischer, and Garth Heutel review the state of research on the interactions between business cycles and environmental policy.
