The results show a negative and significant average effect following the announcement of an LGBT misconduct incident, with an around 0.5% abnormal decrease in market value over the event day and the next trading day. The average magnitude of impact is significantly lower after the #MeToo movement, suggesting that investors tend to be less indulgent regarding inappropriate behavior based on sexual orientation. We also find that firms experiencing a large negative magnitude of impact perform concrete corrective actions to repair their tarnished reputation.},

Using panel data for a sample of French listed companies between 2010 and 2013, we find that CSR engagementconstrain earnings management practices suggesting that managers would comply with the ethical requirements and satisfy stakeholders' interests. The results also show that the effect of CSR on earnings management is particularly stronger in more independent boards and with high institutional ownership structure. These corporate governance devices help mitigating managerial opportunistic behavior.},

address = {Nice, France},
abstract = {The purpose of this study is to shed the light on the effect of corporate social performance on stock market liquidity in the French context. Based on a sample of 100 companies from 2011-2013, our results approve the role of Corporate Social Responsibility (CSR), particularly community engagement and governance in reducing information asymmetry and improving stock market liquidity. This result supports the theoretical legitimacy and reputational hypotheses. Moreover, with the presence of a high proportion of institutional investors, we find a negative impact of CSR activities on market liquidity. These findings may have important implications in terms of the academic and managerial understanding toward the relative benefits of CSR. Indeed, our results highlight the relevance of developing the CSR activities and particularly community engagement and governance by French firms in order to better assess firms' values and improve their stock liquidity. However, institutional investors are not deemed to bean effective corporate governance device for French companies suggesting that stock liquidity could be affected by the way CSR is monitored.},
