Can News about the Future Drive the Business Cycle?


Book Description

Aggregate and sectoral comovement are central features of business cycle data. Therefore, the ability to generate comovement is a natural litmus test for macroeconomic models. But it is a test that most existing models fail. In this paper we propose a unified model that generates both aggregate and sectoral comovement in response to contemporaneous shocks and news shocks about fundamentals. The fundamentals that we consider are aggregate and sectoral TFP shocks as well as investment-specific technical change. The model has three key elements: variable capital utilization, adjustment costs to investment, and a new form of preferences that allow us to parameterize the strength of short-run wealth effects on the labor supply.




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.




Big News: Climate Change and the Business Cycle


Book Description

News drive expectations about the economy's future fundamentals. Climate change is big news: it will impact the economy profoundly but the effect will take some time to materialize in full. Climate-change expectations thus offer a unique opportunity to study the impact of news on the business cycle. We measure these expectations in a representative survey of US consumers. Respondents expect not much of an impact on GDP growth, but perceive a high probability of costly, rare disasters-suggesting they are salient of climate change. Furthermore, expectations vary systematically with socioeconomic characteristics, media consumption, various information treatments and over time. We calibrate a New Keynesian model with rare disasters to key results of the survey and find that shifts in climate change expectations operate like demand shocks and cause sizeable business cycle fluctuations.




Monetary Policy, Inflation, and the Business Cycle


Book Description

The classic introduction to the New Keynesian economic model This revised second edition of Monetary Policy, Inflation, and the Business Cycle provides a rigorous graduate-level introduction to the New Keynesian framework and its applications to monetary policy. The New Keynesian framework is the workhorse for the analysis of monetary policy and its implications for inflation, economic fluctuations, and welfare. A backbone of the new generation of medium-scale models under development at major central banks and international policy institutions, the framework provides the theoretical underpinnings for the price stability–oriented strategies adopted by most central banks in the industrialized world. Using a canonical version of the New Keynesian model as a reference, Jordi Galí explores various issues pertaining to monetary policy's design, including optimal monetary policy and the desirability of simple policy rules. He analyzes several extensions of the baseline model, allowing for cost-push shocks, nominal wage rigidities, and open economy factors. In each case, the effects on monetary policy are addressed, with emphasis on the desirability of inflation-targeting policies. New material includes the zero lower bound on nominal interest rates and an analysis of unemployment’s significance for monetary policy. The most up-to-date introduction to the New Keynesian framework available A single benchmark model used throughout New materials and exercises included An ideal resource for graduate students, researchers, and market analysts




News and Business Cycles in Open Economies


Book Description

It is well known that the neoclassical model does not generate comovement among macroeconomic aggregates in response to news about future total factor productivity. We show that this problem is generally more severe in open economy versions of the neoclassical model. We present an open economy model that generates comovement both in response to sudden stops and to news about future productivity and investment-specific technical change. We find that comovement is easier to generate in the presence of weak short-run wealth effects on the labor supply, adjustment costs to labor, and/or investment, and whenever the real interest rate faced by the economy rises with the level of net foreign debt.




News Shocks in Open Economies


Book Description

This paper explores the effect of news shocks on the current account and other macroeconomic variables using worldwide giant oil discoveries as a directly observable measure of news shocks about future output ? the delay between a discovery and production is on average 4 to 6 years. We first present a two-sector small open economy model in order to predict the responses of macroeconomic aggregates to news of an oil discovery. We then estimate the effects of giant oil discoveries on a large panel of countries. Our empirical estimates are consistent with the predictions of the model. After an oil discovery, the current account and saving rate decline for the first 5 years and then rise sharply during the ensuing years. Investment rises robustly soon after the news arrives, while GDP does not increase until after 5 years. Employment rates fall slightly for a sustained period of time.




The Measurement of Durable Goods Prices


Book Description

American business has recently been under fire, charged with inflated pricing and an inability to compete in the international marketplace. However, the evidence presented in this volume shows that the business community has been unfairly maligned—official measures of inflation and the standard of living have failed to account for progress in the quality of business equipment and consumer goods. Businesses have actually achieved higher productivity at lower prices, and new goods are lighter, faster, more energy efficient, and more reliable than their predecessors. Robert J. Gordon has written the first full-scale work to treat the extent of quality changes over the entire range of durable goods, from autos to aircraft, computers to compressors, from televisions to tractors. He combines and extends existing methods of measurement, drawing data from industry sources, Consumer Reports, and the venerable Sears catalog. Beyond his important finding that the American economy is more sound than officially recognized, Gordon provides a wealth of anecdotes tracing the postwar history of technological progress. Bolstering his argument that improved quality must be accurately measured, Gordon notes, for example, that today's mid-range personal computers outperform the multimillion-dollar mainframes of the 1970s. This remarkable book will be essential reading for economists and those in the business community.




Handbook of Economic Expectations


Book Description

Handbook of Economic Expectations discusses the state-of-the-art in the collection, study and use of expectations data in economics, including the modelling of expectations formation and updating, as well as open questions and directions for future research. The book spans a broad range of fields, approaches and applications using data on subjective expectations that allows us to make progress on fundamental questions around the formation and updating of expectations by economic agents and their information sets. The information included will help us study heterogeneity and potential biases in expectations and analyze impacts on behavior and decision-making under uncertainty. Combines information about the creation of economic expectations and their theories, applications and likely futures Provides a comprehensive summary of economics expectations literature Explores empirical and theoretical dimensions of expectations and their relevance to a wide array of subfields in economics




News and Sovereign Default Risk in Small Open Economies


Book Description

This paper builds a model of sovereign debt in which default risk, interest rates, and debt depend not only on current fundamentals but also on news about future fundamentals. News shocks (NS) affect equilibrium outcomes because they contain info. about the future ability of the gov¿t. to repay its debt. First, in the model with NS not all defaults occur in bad times. Second, the NS help account for key differences between emerging markets and developed economies: as the precision of the news improves the model predicts lower variability of consumption, less counter-cyclical trade balance and interest rate spreads. Finally, the model also captures the hump-shaped relationship between default rates and the precision of news obtained from the data.




Business Cycles


Book Description

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.
