ESG Performance and Stock Market Responses to Geopolitical Turmoil: evidence from the Russia-Ukraine War (Boccaletti, Maranzano, Morelli & Ossola, 2025)

We provide data and code to replicate the results presented in "ESG Performance and Stock Market Responses to Geopolitical Turmoil: evidence from the Russia-Ukraine War" (Boccaletti, Maranzano, Morelli & Ossola, 2025).
The subfolders allow replicating the following:
1. Folder "Event Study - Synthetic" replicates the event study from Section 4
2. Folder "Regressions replication - Table 5 and Table 6" replicates the regression analysis from Section 5.
For each subfolder a README file is provided. It contains information about the reproduction steps.

* VERSION 5 UPDATES *
Compared to version 4, version 5 includes more detailed explanations in the README files. Specifically, it provides additional information about the simulation and replication of the study, and explains the number of observations in the provided dataset for the sub-folder 'Regressions Replication - Tables 5 and Table 6'.

* VERSION 4 UPDATES *
Compared to Version 3, Version 4 of the folder includes more detailed descriptions of the README files and methodological steps. Additionally, it includes the event study's aggregate results.

本数据集提供复现《环境、社会和治理（Environmental, Social, Governance，ESG）表现与股票市场对地缘政治动荡的反应：来自俄乌战争的证据》（Boccaletti、Maranzano、Morelli与Ossola，2025）一文所列研究结果所需的数据与代码。
本数据集的子文件夹可用于复现以下内容：
1. 「事件研究-合成法 (Event Study - Synthetic)」文件夹可复现第4章节的事件研究分析；
2. 「回归复现-表5与表6 (Regressions replication - Table 5 and Table 6)」文件夹可复现第5章节的回归分析。
每个子文件夹均配有README文件，其中包含复现研究结果的具体操作步骤。

* 版本5更新说明 *
相较于版本4，版本5的README文件补充了更为详尽的解释说明：具体而言，新增了本研究的模拟与复现流程相关信息，并针对「回归复现-表5与表6 (Regressions Replication - Tables 5 and Table 6)」子文件夹中的数据集，补充说明了其观测值的数量。

* 版本4更新说明 *
相较于版本3，本文件夹的版本4对README文件与方法论步骤补充了更为细致的描述；此外，还新增了事件研究的汇总结果。
