摘要：In this paper we use a structural VAR model with time-varying parameters and stochasticvolatility to investigate whether the Federal Reserve has responded systematically toasset prices and whether this response has changed over time. To recover the systematiccomponent of monetary policy, we interpret the interest rate equation in the VAR as anextended monetary policy rule responding to infl ation, the output gap, house prices andstock prices. We fi nd some time variation in the coeffi cients for house prices and stockprices but fairly stable coeffi cients over time for infl ation and the output gap. Our resultsindicate that the systematic component of monetary policy in the US, i) attached a positiveweight to real house price growth but lowered it prior to the crisis and eventually raised itagain, and ii) only episodically took real stock price growth into account.
