Mortgages and Monetary Policy
研究了在不完全资产市场下，货币政策通过抵押贷款成本与还款额影响家庭决策的渠道，发现持续性冲击比暂时性冲击有更大实际效应，且浮动利率抵押贷款下传导更强。
Mortgages are prime examples of long-term nominal loans. As a result, under incomplete asset markets, monetary policy can affect household decisions through the cost of new mortgage borrowing and the value of payments on outstanding debt. These channels are distinct from the transmission through real interest rates. A stylized general equilibrium model in corporating these features is developed. Persistent monetary policy shocks, resembling the level factor in the nominal yield curve, have larger real effects than transitory shocks. The transmission is stronger under adjustable- than fixed-rate mortgages. Higher, persistent, inflation benefits homeowners under FRMs but hurts them under ARMs.
