New‐Keynesian Models and Monetary Policy: A Re‐examination of the Stylized Facts*
使用实证新凯恩斯模型匹配美国数据，估计央行偏好、前瞻性行为等关键参数，发现央行对产出稳定关注小、偏好利率平滑，价格设定前瞻性弱而产出决定前瞻性强。
Abstract Using an empirical New‐Keynesian model with optimal discretionary monetary policy, we estimate key parameters—the central bank's preference parameters; the degree of forward‐looking behavior in the determination of inflation and output; and the variances of inflation and output shocks—to match some broad characteristics of U.S. data. The parameterization we obtain implies a small concern for output stability but a large preference for interest rate smoothing, and a small degree of forward‐looking behavior in price‐setting but a large degree of forward‐looking in the determination of output. Our methodology also allows us to carefully examine the consequences of alternative parameterizations and to provide intuition for our results.
