This paper investigates the transmission mechanism of mortgage premium to characterize the relationship between the housing market and the business cycle for the U.S. economy. The model matches the main features of the U.S. housing market and business cycles well. The mortgage premium is crucial for the amplification and propagation of the model to match the data. If the Federal Reserve had exercised pre-emptive monetary policy in 2002Q1, the counter factual analysis suggests that a higher interest rate would have stabilized house price and housing investment volatilities, but would have taken a big toll on real GDP: its volatility remains approximately the same, but the level of GDP contracts dramatically.
