Work-from-home and the risk of securities misconduct

In the wake of the global pandemic, a challenge for CEOs and boards is to set a stakeholder-acceptable organizational balance between remote and traditional office working. However, the risks of work-from-home are not yet fully understood. We describe competing theories that predict the effect on misconduct of a corporate shift to work-from-home. Using internal bank data on securities traders we exploit lockdown variation induced by emergency regulation of the Covid-19 pandemic. Our difference-in-differences analysis reveals that working from home lowers the likelihood of securities misconduct; ultimately those working from home exhibit fewer misconduct alerts. The economic significance of these changes is large. Our study makes an important step toward understanding the link between the balance of work locations and the risk that comes with this tradeoff.     

Securities class actions and conditional conservatism: Evidence from two legal events

We use two US court rulings as exogenous shocks to firms' litigation environment and examine the changes in conservative financial reporting following these court decisions. The Silicon Graphics ruling in 1999 imposed a heightened pleading standard and discouraged the filing of shareholder lawsuits against firms with headquarters in the Ninth Circuit. The Tellabs ruling in 2007, however, effectively reversed the Silicon Graphics ruling and made it easier to file securities litigation against Ninth Circuit firms. We predict and find that the reduced litigation risk following the Silicon Graphics ruling discourages conservative reporting for Ninth Circuit firms. By contrast, the elevated threat of shareholder lawsuits following the Tellabs ruling encourages conservative reporting for Ninth Circuit firms relative to non-Ninth Circuit firms. The disciplining effect of the threat of shareholder lawsuits on conservatism is stronger for firms facing higher ex ante litigation risk. The litigation-risk-induced increase (decrease) in reporting conservatism leads to higher (lower) firm valuations.     

Difference of opinion among investors versus analysts

We construct an investor-based measure of differences of opinion (DO) to investigate the different implications of DO between retail investors (DOR), institutional investors (DOI), and analysts (DOA) on asset pricing. Using Chinese stock data, we find that three DO measures (DOR, DOI, and DOI) are negatively related to future returns; DOI’s ability to predict returns can be partly explained by DOR and DOA, whereas DOR contains incremental information not available from DOI and DOA. DOR is more strongly associated with the severe overvaluation caused by retail investors’ optimism than DOI or DOA, emphasising the specific role of retail investors in China’s market. We further show that DOI and DOA are the results of the differences in their information sets, whereas DOR are the results of different interpretations of public information.     

Security Analysts’ Site Visits and Stock Price Synchronicity

This paper investigates how security analysts’ corporate site visits impact listed firms’ stock-price informativeness. Examining a sample of security analysts’ visits to Chinese listed firms from 2010 to 2019, we find that security analysts incorporate firm-specific information into share prices through site visits, significantly reducing the visited firms’ stock price synchronicity. This finding is robust to an alternative measure of stock price informativeness and a two-stage least-squares approach using the introduction of high-speed rail as the instrumental variable. We also find that the impact of analysts’ site visits on firms’ stock price synchronicity is more pronounced for firms with lower information disclosure quality and poor corporate governance than for other firms. Further analysis on firm characteristics documents that this effect is stronger for large-size firms, firms in the manufacturing industry, and state-owned enterprises.     

巨灾风险管理中的行业损失担保

行业损失担保是一种赔付主要由巨灾所造成的整个保险行业损失所触发的保险连结证券。与传统再保险相似,它也要事先确定合约的涵盖地域、灾害种类、责任限额和有效时间等。但它与传统再保险不同在于,赔付取决于两个损失触发条件,即购买者的实际损失和整个保险行业的损失。本文从行业损失担保的市场发展、定义与运行机制、精算定价等角度,对其进行了系统梳理分析,并把它与其他巨灾风险连接证券进行了比较。
