It finds that both margin trading and short selling can reduce bond yield spread. Additionally, it finds that margin trading lowers firms' debt ratios and increases their credit ratings, which explains the reduced spread. In other words, margin trading can impact investors' decisions by revealing positive information about a firm.Another finding is that short selling lowers the bond yield spread by decreasing earnings management, suggesting that short selling has an impact on investors' decisions through its effect on corporate governance. Our results suggest that margin trading transmits positive information and short selling impacts firms' policies. These results provide support for future regulations of margin trading and short selling.展开更多
以我国融资融券试点为准自然实验,从被审计方的行为选择视角,采用双重差分模型( DID )和倾向得分匹配法( PSM ),考察了放松卖空限制对上市公司审计师选择的影响,发现放松卖空管制会促使上市公司选择审计质量较高的会计师事务所。该效应...以我国融资融券试点为准自然实验,从被审计方的行为选择视角,采用双重差分模型( DID )和倾向得分匹配法( PSM ),考察了放松卖空限制对上市公司审计师选择的影响,发现放松卖空管制会促使上市公司选择审计质量较高的会计师事务所。该效应在非国有企业中更加显著,而且卖空标的公司更加倾向于变更为高质量的会计师事务所。进一步研究发现,卖空机制对高质量审计师选择的影响,并非是融资做多所致,而是主要源于融券做空的卖空压力。本文为我国在条件成熟时全面放开卖空机制以及会计师事务所做大做强并提高审计质量,提供了来自上市公司行为选择的经验证据支持,并提示学界在研究审计师选择时应该考虑卖空机制因素。展开更多
