The book introduces the New Keynesian framework, historically through a literature overview and through a step-by-step derivation of a New Keynesian Phillips curve, an intertemporal IS curve, and a targeting rule for the central bank. This basic version is then expanded by introducing cost and demand shocks and uncertainty. The latter enters the model via second order Taylor approximation instead of linearization. Bringing all equations together results in an equilibrium condition which is simulated with a wide range of parameter values, including possible crisis scenarios. The author finds that accounting for uncertainty – regarding growth and inflation expectations – can lead to lower nominal interest rates set by the central bank.

In recent years, New Keynesian dynamic stochastic general equilibrium (NK DSGE) models have become increasingly popular in the academic literature and in policy analysis. However, the success of these models in reproducing the dynamic behavior of an economy following structural shocks is still disputed. This paper attempts to shed light on this issue. We use a VAR with sign restrictions that are robust to model and parameter uncertainty to estimate the effects of monetary policy, preference, government spending, investment, price markup, technology, and labor supply shocks on macroeconomic variables in the United States and the euro area. In contrast to the NK DSGE models, the empirical results indicate that technology shocks have a positive effect on hours worked, and investment and preference shocks have a positive impact on consumption and investment, respectively. While the former is in line with the predictions of Real Business Cycle models, the latter indicates the relevance of accelerator effects, as described by earlier Keynesian models. We also show that NK DSGE models might overemphasize the contribution of cost-push shocks to business cycle fluctuations while, at the same time, underestimating the importance of other shocks such as changes to technology and investment adjustment costs.

When uncertain about inflation persistence, central banks are well-advised to adopt a robust strategy when setting interest rates. This robust approach, characterized by a "better safe than sorry" philosophy, entails incurring a modest cost to safeguard against a protracted period of deviating inflation. Applied to the post-pandemic period of exceptional uncertainty and elevated inflation, this strategy would have called for a tightening bias. Specifically, a high level of uncertainty surrounding wage, profit, and price dynamics requires a more front-loaded increase in interest rates compared to a baseline scenario which the policymaker fully understands how shocks to those variables are transmitted to inflation and output. This paper provides empirical evidence of such uncertainty and estimates a New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model for the euro area to derive a robust interest rate path for the ECB which serves to illustrate the case for insuring against inflation turning out to have greater persistence.

This book retraces the history of macroeconomics from Keynes's General Theory to the present. Central to it is the contrast between a Keynesian era and a Lucasian - or dynamic stochastic general equilibrium (DSGE) - era, each ruled by distinct methodological standards. In the Keynesian era, the book studies the following theories: Keynesian macroeconomics, monetarism, disequilibrium macro (Patinkin, Leijongufvud, and Clower) non-Walrasian equilibrium models, and first-generation new Keynesian models. Three stages are identified in the DSGE era: new classical macro (Lucas), RBC modelling, and second-generation new Keynesian modeling. The book also examines a few selected works aimed at presenting alternatives to Lucasian macro. While not eschewing analytical content, Michel De Vroey focuses on substantive assessments, and the models studied are presented in a pedagogical and vivid yet critical way.

Economists consider the legacy of Karl Brunner’s monetarism and its influence on current debates over monetary policy. Monetarism emerged in the 1950s and 1960s as a school of economic thought that questioned certain tenets of Keynesianism. Emphasizing the monetary nature of inflation and the responsibility of central banks for price stability, monetarism held sway in the inflation-plagued 1970s, but saw its influence begin to decline in the 1980s. Although Milton Friedman is the economist most closely associated with the development of monetarism, it was Karl Brunner (1916–1989) who introduced the term into the current vocabulary of economics and shaped its meaning. In this volume, leading economists—many of them Brunner’s friends and former colleagues—consider the influence of Brunner’s monetarism on current debates over monetary policy. Some contributors were participants in debates between Keynesians and monetarists; others analyze specific aspects of monetarism as theorized by Brunner and his close collaborator Allan Meltzer, or address its influence on US and European monetary policy. Others take the opportunity to examine Brunner-Meltzer monetarism through the lens of contemporary macroeconomics and monetary models. The book grows out of a symposium that marked the 100th anniversary of Brunner’s birth. Contributors Ernst Baltensperger, Michael D.

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.
