Estimation of Monetary Policy Preferences in a Forward-Looking MOdel: A Bayesian Approach
采用贝叶斯方法在欧元区一般均衡框架下估计货币政策偏好参数，发现通胀波动仍是主要关注点，利率平滑和产出缺口也较重要。
In this paper we adopt a Bayesian approach toward the estimation of monetary policy preference parameters in a general equilibrium framework for the euro area. We assume that monetary policy authorities optimize an intertemporal quadratic loss function under commitment and study two alternative specifications of the loss function. The first specification includes inflation, output gap, and the interest rate differential as targets. The second loss function includes an additional wage-inflation target. The weights assigned to target variables - i.e., monetary policy preferences - are estimated jointly with the structural model parameters. The results imply that inflation variability remains the main concern of optimal monetary policy. Interest rate smoothing and the output gap appear to be, to a lesser extent, important target variables as well. Due to the time-inconsistency problem under commitment, we propose to initialize the estimates by a presample period of forty quarters. This allows us to approach, empirically, the timeless-perspective framework.
