This chapter of the Research Handbook of Inflation (2025) reviews the evolution and current relevance of medium-scale New Keynesian Dynamic Stochastic General Equilibrium (DSGE) models, which serve as part of the core analytical framework in central banks and academic macroeconomics. The chapter...

Imposing restrictions on policy rule coefficients in vector autoregressive (VAR) models enhances the identification of monetary policy shocks obtained with sign and narrative restrictions. Monte Carlo simulations and empirical analyses for the United States and the Euro area support this result....

This paper argues that the common practice of Bayesian estimation in applied macroeconomic DSGE modeling can lead to severely biased results when the imposed prior beliefs are misspecified. We demonstrate, through controlled Monte Carlo experiments on two canonical DSGE models (a Real Business...

This study examines how economic inequality influences the effectiveness of fiscal policy using a three-agent New Keynesian DSGE model with incomplete financial markets. The findings suggest that economies with a high share of liquidity-constrained households exhibit larger fiscal multipliers...
