本文旨在探討政治是否影響貨幣政策。首先藉由 Iacoviello and Neri (2010) 的動態隨機一般均衡模型及福利分析,建構美國、英國、加拿大、澳洲及紐西蘭等5國的最適利率法則。接著分析各國偏離最適利率的情形,與其政府及貨幣當局主政者的關聯。實證結果發現,政治因素導致貨幣政策偏離最適泰勒法則,在美、加、澳、紐等4國是一種普遍的現象。
This thesis examines the link between politics and deviations of the optimal interest rate rule in the United States, the United Kingdom, Canada, Australia and New Zealand, respectively, a fter estimating the optimal Taylor rule with the dynamic stochastic general equilibrium (DSGE) model proposed by Iacoviello and Neri (2010) and a welfare-based analysis. Empirical results show that Taylor rule deviations are commonly caused by politics in the countries except the United Kingdom.
