论文摘要
我们研究了2022年2月在俄罗斯入侵乌克兰之前和期间，基于Google趋势的特定事件注意指数（基于Google趋势）的影响。我们将分析扩展到在51个全球股市内对俄罗斯的地理接近和经济开放性的重要性。我们的结果表明，在入侵开始和入侵期间，有36个国家对冲突的关注很大，这有助于预测波动。我们发现，在对俄罗斯及其附近的经济开放程度更高的国家中，注意力的影响更大。
We study the impact of event-specific attention indices -- based on Google Trends -- in predictive price variation models before and during the Russian invasion of Ukraine in February 2022. We extend our analyses to the importance of geographical proximity and economic openness to Russia within 51 global equity markets. Our results demonstrate that 36 countries show significant attention to the conflict at the onset of and during the invasion, which helps predict volatility. We find that the impact of attention is more significant in countries with a higher degree of economic openness to Russia and those nearer to it.
