Abstract

This paper analyzes the conduct of central banks in seven advanced economies by comparing observed and optimal monetary policies using model-consistent welfare measures. The study emphasizes the role of inertia in output gaps and in price and wage dynamics, modeling inertia through duration-dependent price and wage adjustments. By incorporating these mechanisms into a simple New Keynesian model, the paper derives a welfare-based criterion and performs counterfactual policy simulations under commitment and discretion. The analysis identifies common patterns and country-specific features in the conduct of monetary policy across Australia, Canada, France, Germany, Italy, the United Kingdom, and the United States.
