Book Description
Output and asset returns are highly positively correlated across the U.S. and the remaining major industrialized countries. Standard business cycle models that assume flexible prices and wages, in the Real Business Cycle (RBC) tradition, have great difficulties explaining this fact. This paper presents a dynamic-optimizing stochastic general equilibrium model of a two-country world with sticky nominal prices and wages. In RBC models, money supply shocks have a negligible effect on real variables. This changes when nominal rigidities are assumed. The nominal rigidities model here predicts that an exogenous money supply increase, in a given country, induces a sizable rise in that country's output, consumption and investment, a fall in its interest rate, as well as a nominal and real depreciation of its currency. Foreign output, consumption and investment are likewise predicted to rise. Nominal rigidities influence also the response of the economy to productivity shocks: in the nominal rigidities structure here, these shocks induce output responses that are much more strongly positively correlated across countries, than predicted responses to productivity shocks generated by standard RBC models. The structure here generates thus cross-country correlations of output (and of aset returns) that are markedly higher, and hence closer to the data, than the correlations that obtain under flexible prices and wages. monetary policy, asset returns.

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

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.

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.

Book Description
An essential introduction to one of the most timely and important subjects in economics International Macroeconomics presents a rigorous and theoretically elegant treatment of real-world international macroeconomic problems, incorporating the latest economic research while maintaining a microfounded, optimizing, and dynamic general equilibrium approach. This one-of-a-kind textbook introduces a basic model and applies it to fundamental questions in international economics, including the determinants of the current account in small and large economies, processes of adjustment to shocks, the determinants of the real exchange rate, the role of fixed and flexible exchange rates in models with nominal rigidities, and interactions between monetary and fiscal policy. The book confronts theoretical predictions using actual data, highlighting both the power and limits of given theories and encouraging critical thinking. Provides a rigorous and elegant treatment of fundamental questions in international macroeconomicsBrings undergraduate and master’s instruction in line with modern economic researchFollows a microfounded, optimizing, and dynamic general equilibrium approachAddresses fundamental questions in international economics, such as the role of capital controls in the presence of financial frictions and balance-of-payments crisesUses real-world data to test the predictions of theoretical modelsFeatures a wealth of exercises at the end of each chapter that challenge students to hone their theoretical skills and scrutinize the empirical relevance of modelsAccompanied by a website with lecture slides for every chapter

Book Description
The price adjustment process is crucial to almost any macroeconomic issue. Current macroeconomic literature features widely different models ranking from instantaneous price adjustment to completely rigid prices. Professor Andersen provides a comprehensive analysis of reasons why prices may fail to adjust instantaneously to changes in market conditions. This unified treatment will allow the reader to understand the mechanisms at work without becoming lost in technical details. This volume covers both real and nominal price rigidities and integrates existing results from the literature with new results on causes for failures of price adjustment. The analysis of real price rigidities includes inventories, customer markets, search and collusive behaviour. Due to the focus on macroeconomic implications, the analysis of nominal price rigidities is extensive and includes menu costs, informational problems, asynchronized price setting as well as the interaction between price and wage setting. Professor Andersen's own theoretical work on imperfect information, a prime source of price and wage rigidity, is given prominence in the book. The volume is thus a combination of a valuable survey of the literature, and an original expression of future possible research avenues.
