Asset Prices and Assymetries in the Fed's Interest Rate Rule : a Financial Approach

Abstract

Financial Newspapers have for long suggested that the Fed tends to provide additional Liquidity when the Stock Market thumbs. We provide a theoretical Explanation for this Behaviour that builds on the Methodology developed by Romaniuk (2008) for a central Banker with two main Goals, Output and Price stability. In this Paper, the Policymaker behaves as a Portfolio Manager who aims at stabilizing Output, Goods Prices, as well as Asset Prices. An optimal, Time-varying Interest Rate Rule is obtained as the Merton's (1971) continuous Time Solution to the Portfolio Manager's Problem. In a second Step, we infer the optimal Interest Rate Rule of a central Bank that can react differently to positive and negative Variations in the Stock Market.
