低频宏观经济变量对高频电价重要吗?

Are low frequency macroeconomic variables important for high frequency electricity prices?

Claudia Foroni, Francesco Ravazzolo, Luca Rossini

摘要:

最近的研究发现,预测电价是非常相关的。在许多应用中,通过使用自己的滞后或可再生能源来预测每日电价可能会很有趣。然而,最近能源价格的动荡和俄罗斯-乌克兰战争使人们更加重视评估工业生产和采购经理人指数产出调查在预测每日电价方面的相关性。我们开发了一个贝叶斯反向无限制MIDAS模型,该模型解释了德国和意大利的每日价格和月度宏观变量之间的频率不匹配。我们发现,包括宏观经济低频变量是更重要的是通过点和密度措施的短期比中期的视野。特别是,通过结合硬信息和软信息,准确性得到提高,而仅使用调查数据的预测不如仅使用工业生产数据的预测准确。

英文摘要:

Recent research finds that forecasting electricity prices is very relevant. In many applications, it might be interesting to predict daily electricity prices by using their own lags or renewable energy sources. However, the recent turmoil of energy prices and the Russian-Ukrainian war increased attention in evaluating the relevance of industrial production and the Purchasing Managers' Index output survey in forecasting the daily electricity prices. We develop a Bayesian reverse unrestricted MIDAS model which accounts for the mismatch in frequency between the daily prices and the monthly macro variables in Germany and Italy. We find that the inclusion of macroeconomic low frequency variables is more important for short than medium term horizons by means of point and density measures. In particular, accuracy increases by combining hard and soft information, while using only surveys gives less accurate forecasts than using only industrial production data.
