U.S. Monetary Policy Surprises: Identification with Shifts and Rotations in the Term Structure
构建模型从收益率曲线期限结构中提取货币政策意外指标，利用异方差性识别潜在因子，发现不同期限结构反应对应不同类型的货币政策冲击。
We develop a model to extract measures of monetary policy surprises from the maturity structure of the yield curve. The model endogenously allows for the fact that the yield curve may either shift or rotate in response to monetary policy shocks. A latent factor model approach with identification through heteroskedasticity harnesses the term structure to extract monetary policy shocks. The approach offers informational advantages over event studies. Results from the U.S. term structure from 1994 strongly support the hypothesis that differing term structure responses are reactions to different types of monetary policy shock, rather than differing reactions to the same policy shock.
