Abstract Monetary policy rules describe how policy interest rates respond to macroeconomic developments. These rules incorporate forward-looking models that require instruments for consistent estimation. The use of standard instruments leads to weak identification of forward-looking rules. We combine principal component analysis with hard thresholding to construct new instruments based on high-dimensional macro data. Component-based instruments enhance the identification of policy rules relative to standard results. The finding is attributed to specific variables in the data.
