Are Weekly Inflation Forecasts Informative?*
利用共同因子方法，将宏观经济发布和修正的实时信息纳入瑞士核心通胀的周度更新，发现至少每月两次更新预测是有价值的。
Abstract Are weekly inflation forecasts informative? Although several central banks review and discuss monetary policy issues on a bi‐weekly basis, there have been no attempts by analysts to construct systematic estimates of core inflation that supports such a decision‐making schedule. The timeliness of news releases are recognized to be an important information source in real‐time estimation. We incorporate real‐time information from macroeconomic releases and revisions into our weekly updates of monthly Swiss core inflation using a common factor procedure. The weekly estimates for Swiss core inflation show that it is worthwhile to update the forecast at least twice a month.
