“…First, to the best of our knowledge, this study constitutes the first effort to explore a new determinant of stock price crash risk from the perspective of principal-principal agency problems. Prior studies have documented several factors that affect stock price crash risk, including mandatory adoption of International Financial Reporting Standards (IFRS) (DeFond et al, 2015), religion (Callen & Fang, 2015), tax avoidance (Kim et al, 2011a), equity incentives (Kim et al, 2011b), financial analysts (Xu, Jiang, Chan, & Yi, 2013), institutional investors (An & Zhang, 2013;Callen & Fang, 2013), financial reporting opacity (Kim & Zhang, 2014), accounting conservatism (Kim & Zhang, 2016), management excess perks (Xu et al, 2014), and directors' and officers' liability insurance (Yuan et al, 2016). Unlike the prior studies, our study focuses on controlling shareholders' self-interest incentives, and with the perspective of principal-principal agency problems we explore the impact of the reform in China on stock price crash risk.…”
