Optimal Simple Objectives for Monetary Policy when Banks Matter
We reconsider the design of welfare-optimal monetary policy when financing frictions impair the supply of bank credit, and when the objectives set for monetary policy must be simple enough to be implementable and allow for effective accountability. We show that a flexible inflation targeting approach that places weight on stabilizing inflation, a measure of resource utilization, and a financial variable produces welfare benefits that are almost indistinguishable from fully-optimal Ramsey policy. The macro-financial trade-off in our estimated model of the euro area turns out to be modest, implying that the effects of financial frictions can be ameliorated at little cost in terms of inflation. A range of different financial objectives and policy preferences lead to similar conclusions.
Has the Phillips Curve Become Steeper?
This paper analyzes whether structural changes in the aftermath of the pandemic have steepened the Phillips curves in advanced economies, reversing the flattening observed in recent decades and reducing the sacrifice ratio associated with disinflation. Particularly, analysis of granular price quote data from the UK indicates that increased digitalization may have raised price flexibility, while de-globalization may have made inflation more responsive to domestic economic conditions again. Using sectoral data from 24 advanced economies in Europe, higher digitalization and lower trade intensity are shown to be associated with steeper Phillips curves. Post-pandemic Phillips curve estimates indicate some steepening in the UK, Spain, Italy and the euro area as a whole, but at magnitudes that are too small to explain the entire surge in inflation in 2021–22, suggesting an important role for outward shifts in the Phillips curve.
Monetary Policy and Macroprudential Regulation with Financial Frictions
An integrated analysis of how financial frictions can be accounted for in macroeconomic models built to study monetary policy and macroprudential regulation. Since the global financial crisis, there has been a renewed effort to emphasize financial frictions in designing closed- and open-economy macroeconomic models for monetary and macroprudential policy analysis. Drawing on the extensive literature of the past decade as well as his own contributions, in this book Pierre-Richard Agénor provides a unified set of theoretical and quantitative macroeconomic models with financial frictions to explore issues that have emerged in the wake of the crisis. These include the need to understand better ...

Designing a Simple Loss Function for Central Banks
Yes, it makes a lot of sense. This paper studies how to design simple loss functions for central banks, as parsimonious approximations to social welfare. We show, both analytically and quantitatively, that simple loss functions should feature a high weight on measures of economic activity, sometimes even larger than the weight on inflation. Two main factors drive our result. First, stabilizing economic activity also stabilizes other welfare relevant variables. Second, the estimated model features mitigated inflation distortions due to a low elasticity of substitution between monopolistic goods and a low interest rate sensitivity of demand. The result holds up in the presence of measurement errors, with large shocks that generate a trade-off between stabilizing inflation and resource utilization, and also when ensuring a low probability of hitting the zero lower bound on interest rates.
Monetary Policy with Uncertain Inflation Persistence
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.

Macroeconomic Costs of Higher Bank Capital and Liquidity Requirements
This paper uses a DSGE model with banks and financial frictions in credit markets to assess the medium-term macroeconomic costs of increasing capital and liquidity requirements. The analysis indicates that the macroeconomic costs of such measures are sensitive to the length of the implementation period as well as to the adjustment strategy used by banks, and the scope for monetary policy to respond to the regulatory changes.
Unemployment Fluctuations and Stabilization Policies
A new approach for introducing unemployment into the New Keynesian framework. The past fifteen years have witnessed the rise of the New Keynesian model as a framework of reference for the analysis of fluctuations and stabilization policies. That framework, which combines the rigor and internal consistency of dynamic general equilibrium models with such typically Keynesian assumptions as monopolistic competition and nominal rigidities, makes possible a meaningful, welfare-based analysis of the effects of monetary policy rules. But the conspicuous absence of unemployment from the standard New Keynesian model has given rise to both criticism and attempts to rectify this anomaly. In this book, J...
