This study empirically examines how reported corporate misconducts affect the stock returns of US firms. As the reported misconducts are broadcasted in the newspaper outlets, the cumulative abnormal return (CAR) is -4.1%. Involvement in a reported corporate misconduct gets punished by market participants especially when the act of reported misconduct is blamed on the level of the corporation rather than in involvement of a specific individual, when reported misconducts take place in the home market, and when the linguistic tone used in the newspaper article is negative. Financial penalties imposed, firm size, leverage, revenue growth, and the level of firm foreign exposure are found to have significant impact on the returns during the period of observation. The results suggest that investors recognize the importance to penalize firms in the financial markets when firms act unethically.
本研究实证检验了已报道的公司不当行为如何影响美国公司的股票回报。由于已报道的不当行为在报纸上公布,累积异常回报(CAR)为-4.1%。当市场参与者认为不当行为是由公司层面而非特定个人引起,当不当行为发生在国内市场,以及当报纸文章使用的语言语气为负面时,公司参与已报道的公司不当行为会受到市场参与者的惩罚。发现金融罚款、公司规模、杠杆率、收入增长和公司对外投资水平对观察期内的回报有重大影响。结果表明,当公司不道德行为时,投资者认识到在金融市场上对公司进行处罚的重要性。
