In this study, we use the prevailing GARCH-MIDAS model to explore the forecasting performance of world uncertainty index (WUI) in crude oil volatility. Our empirical results indicate the WUI can outperform the economic policy uncertainty (EPU) and geopolitical risk index (GPR). Using the encompassing test, our study provides strong evidences that the predictive content from WUI can encompass the EPU and GPR in predicting crude oil volatility.

原油波动率预测:来自世界不确定性指数的新证据

在本研究中,我们使用流行的 GARCH-MIDAS 模型来探索世界不确定性指数 (WUI) 在原油波动中的预测性能。我们的实证结果表明 WUI 的表现优于经济政策不确定性 (EPU) 和地缘政治风险指数 (GPR)。使用包含测试,我们的研究提供了强有力的证据表明 WUI 的预测内容可以包含 EPU 和 GPR 来预测原油波动。
