Over‐investment or risk mitigation? Corporate social responsibility in Asia‐Pacific,Europe, Japan,and the United States

We study the relationship of corporate social responsibility (CSR) and the distribution of stock returns for an international sample. Firms with a high level of CSR generally exhibit superior stock price synchronicity in the markets of Europe, Japan, and the United States. In particular, we identify optimal levels of CSR to minimize idiosyncratic risk for each region. Moreover, CSR has a mitigating effect on crash risk in Europe and the United States. In contrast, firms from the Asia‐Pacific region display CSR over‐investment followed by a higher crash risk. This appears to be a consequence of globalization, which forces firms from Asia‐Pacific to overinvest in CSR to adapt western standards.     

Fair value disclosures and crash risk

In response to the public criticism of the inadequate disclosures mandated by SFAS No. 157, Fair Value Measurements, the FASB issued ASU (Accounting Standards Update) 2010–06, Improving Disclosures about Fair Value Measurements, and ASU 2011–04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements, in an effort to increase the reporting transparency. We examine whether the increased fair value disclosures required by these two updates effectively decrease crash risk, defined as the frequency of extreme negative stock returns. In support of the hypothesis, we find that increased transparency from these updates reduces crash risk among U.S. banking firms and that the reduction is greater in banks that have a higher level of Level 3 financial assets.     

Short interest and stock price crash risk

Using a large sample of U.S. public firms, we find robust evidence that short interest is positively related to one-year ahead stock price crash risk. The evidence is consistent with the view that short sellers are able to detect bad news hoarding by managers. Additional findings show that the positive relation between short interest and future crash risk is more salient for firms with weak governance mechanisms, excessive risk-taking behavior, and high information asymmetry between managers and shareholders. Empirical support is provided showing that the relation between short interest and crash risk is driven by bad news hoarding.     

转移支付与地方政府支出规模膨胀——基于中国预算制度的一个实证解释

自2000年以来,为了缩小地区间差距和促进基本公共服务均等化,我国的财政转移支付规模迅速扩大。本文利用1994-2015年省级年度数据发现,地方政府获得的一般性转移支付和专项转移支付每增加1元,年度一般预算财政支出将分别增加1.61元和2.12元,远远超过本地财政收入增加所产生的影响。这也意味着财政转移支付在我国产生了较大的“粘蝇纸效应”。在2010年提前下达固定数额转移支付指标改革后,一般性转移支付的“粘蝇纸效应”有所下降。使用分月数据的回归结果显示,“年底突击花钱”对专项转移支付“粘蝇纸效应”的贡献最大。本文的研究表明,转移支付引发的地方财政收入的不确定性、转移支付下拨时滞以及刚性的年度预算平衡制度是导致我国地方政府支出规模膨胀的重要原因。本文的研究结论意味着,中央应进一步规范转移支付制度、扩大提前下达转移支付指标的范围、加快转移支付的拨付进度、建立和完善跨年度预算平衡机制、积极防范转移支付的道德风险问题。地方各级政府应该加强预算执行管理,强化预算约束力。     

Economic policy uncertainty and stock price crash risk

This paper studies the impact of economic policy uncertainty on stock price crash risk using data from China. We develop a new index to measure Chinese economic policy uncertainty and find that economic policy uncertainty has a remarkable positive effect on stock price crash risk. However, the effect reverses later. The results also indicate that the positive effect of economic policy uncertainty on stock price crash risk is more prominent for state‐owned enterprises. Moreover, this effect is more prominent for firms with higher information asymmetry and firms with greater disagreement among investors, indicating that economic policy uncertainty affects crash risk through two mechanisms: managers’ concealment of bad news and investors’ heterogeneous beliefs.     

山高皇帝远:地理距离与上市公司股价崩盘风险的经验证据

鉴于信息不对称程度、制度实施成本和心理文化差异，文章提出"监管距离"假说，认为监管者和被监管者之间距离远近可以影响监管效果。实证分析中国沪深上市公司数据，文章从非对称风险视角出发，研讨了上市公司注册地距所在地中国证监会派出机构的地理距离对公司层面的股价崩盘风险的影响。我们发现，监管机构与上市公司总部的地理距离越远，该上市公司股价的崩盘风险越大。进一步分析发现，如果开通高铁或者上市公司所在地社会信任水平足够高，那么监管距离和崩盘风险的正相关关系是不显著的；如果监管负担严重或政府效率低下，那么监管距离和崩盘风险之间正相关关系更为显著。文章认为，地理距离具有监管信息效应、监管威慑效应和监管执行效应，能够影响股价崩盘风险。也就是说，"山高皇帝远"可以改变上市公司行为，提高金融监管效率不应忽视非正式制度的影响。     

The impact of investor structure on stock price crash sensitivity: Evidence from China's stock market

Stock price crash sensitivity refers to the conditional probability of a stock crash when the market collapses. It focuses on individual stocks' sensitivity to the market crash and can affect stock pricing significantly. Although the crash sensitivity of China's stock market is very high as a whole (Weigert, 2016), different individual stocks show varying degrees of crash sensitivity. This paper, adopting the perspective of institutional investors, explores the reasons for the difference in crash sensitivity in China's stock market, and finds that: First, institutional investors' shareholdings is positively related to firms' stock price crash sensitivity. However, after dividing institutional investors into professional (represented by financial institutions) and non-professional institutional investors (represented by general legal persons), we find that only professional institutional investors' shareholdings is negatively related to firms' stock price crash sensitivity. Second, the impact of professional institutional investors on the crash sensitivity is influenced by stock liquidity and media sentiment: when the stock liquidity of listed companies is good or the media sentiment is strong, the negative impact of professional institutional investors on the crash sensitivity is accordingly high. This paper, by highlighting the investor structure, attempts a pioneering exploration of the influencing factors of the difference in stock price crash sensitivity in China. Our empirical results enrich research on stock price crash sensitivity and the heterogeneity of institutional investors. They can also serve to guide regulatory authorities' development of institutional investors and efforts to maintain market stability.     

Environmental,social, and governance practices and perceived tail risk

Using the implied volatility smirk on individual equity securities to measure perceived tail risk, we find that better environmental, social and governance (ESG) practices significantly reduce ex-ante expectations of a left-tail event. Our findings are robust to using multiple model specifications and to adjusting for potential endogeneity concerns. We also show that, while practices in each ESG pillar are important in reducing perceived tail risk, the environmental pillar plays the most important role. Our results indicate that investors consider strong ESG practices to be insurance against left-tail events rather than wasteful investment borne out of managers’ own values or self-interest.     

中国股市的崩盘系统性风险与投资者行为偏好

股价崩盘作为金融市场上普遍存在并且具有广泛影响力的极端现象,对股票的定价产生了至关重要的作用。本文主要研究我国股市中股票的崩盘系统性风险,研究发现:(1)股票的崩盘系统性风险与预期收益率显著正相关,并且对冲组合可以获得8.86%的年化收益;(2)投资者的博彩型股票偏好和吉祥数字偏好都会显著影响崩盘系统性风险与预期收益率之间的关系。本文的研究对于进行投资决策、风险管理以及理解投资者行为都具有参考意义。     

纵向兼任高管能降低股价崩盘风险吗?

纵向兼任高管究竟会加强大股东对管理层的监督,减少管理层机会主义行为,提升公司治理水平;还是会强化大股东对上市公司的控制,提升其私有权收益的获取能力,增加企业风险？为此,文章将以2007年-2017年中国A股上市公司为研究样本,探究纵向兼任高管如何影响企业的股价崩盘风险。研究发现,纵向兼任高管显著降低了公司未来股价崩盘风险;在进行Heckman两阶段模型、倾向得分匹配等稳健性检验后,这一结论依然成立。同时,文章进一步研究发现,纵向兼任高管在"监督效应"和"更少掏空效应"共同作用下降低了股价崩盘风险;且当纵向兼任高管权力越大时,即纵向兼任董事长时,对公司未来股价崩盘风险的降低作用越明显。文章不但深化了股价崩盘风险影响因素的研究,而且有助于我们全面认识纵向兼任高管这一关系在公司治理中的作用,这对于完善公司治理、防范股价崩盘风险,进而促进我国资本市场的健康发展有重要的意义。
