This paper examines whether or not stock return responds asymmetrically to monetary policy shocks. We use over-night rate volatility to measure monetary policy and apply Component-GARCH-Constant Jump and ARJI-Trend model to capture expected and unexpected effects of government's monetary policy on the stock return in American, Canada, Japan, and Britain. Considering the non-normality features of these assets returns, this paper use skewed student t distribution to estimate the relationship between the permanent and transitory components of the conditional variance and the frequency and intensity of jump of stock return.

本文探讨货币政策对於股市报酬之影响，选取货币政策代理变数－金融业隔夜拆款利率在分别采用Component-GARCH-Constant Jump与ARJI-Trend模型，并同时考量报酬率呈现非常态之特性，因此采用偏态t分配(skewed student t-distribution)进行估计条件变异数的恒常与移转部份及跳跃机率与跳跃频率，以捕捉政府实施预期及非预期的货币政策对股市报酬的影响，分析在预期及非预期的货币政策冲击下对股市的影响是否存在不同之效果。
