Monetary policy at the zero interest bound: A model comparison exercise

In this paper, we summarize the findings from zero-interest-bound simulation exercises conducted on the policy/forecasting models of the three major central banks. After imposing a fixed-period zero-interest-bound episode on each model, we consider common variations in the monetary-policy reaction function to minimize the macro-economic consequences of such a deflationary regime. Although there is some heterogeneity in the ranking of these remedial policies, reflecting the different properties of the models, we find that more aggressive policy rules and price-targeting rules are potentially candidates for robust monetary strategies.
