Data for: Short-run and long-run effects of ESG policies on value creation and the cost of equity of firms

We compile all accounting and market data from the Datastream database. Specifically, we use the ‘Worldscope Balance Sheet’ and ‘Worldscope Profit & Loss Statement’ templates to compile the financial statements of all listed firms in the four largest economies in the euro zone by GDP (i.e. Germany, France, Italy and Spain) for which Refinitiv® ESG Scores are available. The data series comprise 487 firms and a time interval of annual data that goes from 2016 to 2020. Variations in ESG scores are determined using Refinitiv® ESG Scores, specifically, the Environmental Score, the Social Score and the Governance Score.我们从Datastream数据库中采集全部会计与市场数据。具体而言，我们采用“Worldscope资产负债表”与“Worldscope利润表”模板，为按GDP总量排名的欧元区四大经济体（德国、法国、意大利及西班牙）中可获取路孚特（Refinitiv®）ESG评分的所有上市公司编制财务报表。本数据集涵盖487家样本企业，时间跨度为2016年至2020年的年度数据。 ESG评分的差异以路孚特（Refinitiv®）ESG评分进行测算，具体包含环境评分（Environmental Score）、社会评分（Social Score）与治理评分（Governance Score）。
