Abstract
In this study, I forecast CPI inflation in Russia by the method of Dynamic Model Averaging (Raftery et al., 2010; Koop and Korobilis, 2012) pseudo out-of-sample on historical data. This method can be viewed as an extension of the Bayesian Model Averaging where the identity of a model that generates data and model parameters are allowed to change over time. The DMA is shown not to produce forecasts superior to simpler benchmarks even if a subset of individual predictors is pre-selected “with the benefit of hindsight” on the full sample. The two groups of predictors that feature the highest average values of the posterior inclusion probability are loans to non-financial firms and individuals along with actual and anticipated wages.
在本研究中,我采用动态模型平均的方法预测俄罗斯的CPI通胀(Raftery et al., 2010;Koop和Korobilis, 2012)历史数据的伪样本外。这种方法可以看作是贝叶斯模型平均的扩展,其中允许生成数据和模型参数的模型的身份随时间变化。事实证明,DMA的预测结果并不优于更简单的基准,即使是在“事后诸明的好处”下,对整个样本预先选择了个别预测指标的子集。后验包容概率平均值最高的两组预测因子是对非金融公司和个人的贷款以及实际和预期工资。
