Unconventional Monetary Policy and International Risk Premia
研究了货币政策与外汇风险溢价、期限溢价的关系，包括零利率下限时期，通过高频货币政策意外识别冲击，并区分前瞻指引和资产购买的效果。
Abstract We assess the relationship between monetary policy, foreign exchange risk premia, and term premia including the period at the zero lower bound (ZLB). We estimate a structural vector autoregression including U.S. and foreign interest rates and exchange rates and identify monetary policy shocks through a method that uses high‐frequency monetary policy surprises as the external instrument that achieves identification without using implausible restrictions. We split out effects of different types of monetary policy surprises that apply at the ZLB, including forward guidance and asset purchases. This allows us to measure the effects of policy shocks on expectations, and hence risk premia.
