When is a MAX not the MAX? How news resolves information uncertainty

A well-known asset pricing anomaly, the “MAX” effect, measured by the maximum daily return in the past month, depicts stocks’ lottery-like features and investor gambling behaviour. Using the comprehensive stock-level Dow Jones (DJNS) news database between 1979 and 2016, we consider in a empirical setting how the presence of news reports affects these lottery-type stocks. We find an augmented negative relationship between MAX stocks without news and expected returns, whereby MAX with news coverage generates return momentum. The differing future return relationships between MAX stocks with and without news appears to be best explained by information uncertainty mitigation upon news arrival. Overall, our findings suggest that news plays a role in resolving information uncertainty in the stock market.     

Business and financial information integration and voluntary management earnings forecasts

In this study, the impact of business and financial information integration (BFII) on the voluntary management earnings forecasts (VMEFs) of listed firms in China between 2008 and 2018 is investigated. Drawing on litigation cost and ability signaling theories, we find that the adoption of BFII encourages top managers to disclose VMEFs. BFII firms are identified through the textual analysis of management discussion and analysis (MD&A) reports, and the empirical results indicate that BFII firms have a higher probability and frequency of issuing VMEFs than non-BFII firms. The results remain robust after we identify causality by applying a propensity score matching and difference-in-differences (PSM-DID) test and use an alternate measure of BFII. Further tests show that BFII firms issue more accurate VMEFs and are able to issue them at an earlier stage. We also find that the positive relationship between BFII and VMEFs is weakened if the media expresses concern about the uncertainty of BFII adoption.

Making the news: Heterogeneous media coverage and corporate litigation

Research summary: This study explores how relative prominence shapes rivalry between firms. Corporate litigation, an increasingly costly domain of interfirm rivalry, is threatening not just because of the immediate legal stakes but because of the indirect losses that unwanted negative publicity inflicts on defendants. I argue that potential defendants' incentives to avoid such losses create a source of value that firms can capture by agreeing to forgo litigation. The more prominent a firm is relative to rivals, the greater its threat and the more value it stands to capture from potential targets by sparing them from litigation. Managerial summary: The power to attract media attention can be valuable to firms beyond its role in managing relations with investors or the public. It can also provide leverage against industry rivals. Being sued by a prominent firm carries the threat of potential damaging publicity, especially for lesser‐known rivals. Firms may be able to leverage this threat to elicit concessions in return for sparing rivals from litigation. Prominent firms stand to benefit not just from eliciting concessions from rivals but from the ability to do so while avoiding costly litigation. Data from the semiconductor industry show that firms that command much higher levels of media coverage than rivals are able to avoid litigation more often than firms with comparable or lower levels of media coverage.

住房公积金制度参缴影响因素分析及改革路径选择

进一步扩大住房公积金的覆盖率,将灵活就业人员等纳入住房公积金制度,是近年来国家致力于提高住房公积金制度参保率以提升制度保障力度的重要措施。然而,规定可纳入住房公积金制度的新增群体在实施过程中是否真的愿意参与进来?住房公积金制度扩面是否能顺利推进?仍需进一步探讨与研究。在住房公积金资金积累规模不断扩大且增速加快的发展进程中,采用二元logistic回归模型对住房公积金制度参缴意愿及影响因素进行分析,提出扩大住房公积金制度实际覆盖率,增加制度公平性的对策与建议。     

我国基本养老保险扩面的收入分配效应研究

文章基于一般均衡分析框架,通过构建“统账结合”制基本养老保险的异质性跨期交叠一般均衡动态模型,引入国发〔2005〕38号文的主要内容,利用政策仿真、参数估值和敏感性检验等方法,重点研究了养老保险制度覆盖面扩展的收入分配和再分配效应,并进行了理论推导和实证测算。结果发现：（1）我国基本养老保险扩面具有明显的收入分配和再分配效应,且再分配效应是累进的,发生了从城镇企业职工为代表的高收入者向以灵活就业人员和农民工为代表的低收入者的收入转移;（2）个人账户发挥了平滑作用,有利于改善不同类型劳动者终生的收入分配,但不利于收入再分配的改善;（3）社会统筹账户具有较强的收入再分配效应,有利于改善不同类型劳动者的收入再分配,缩小收入差距。参数敏感性检验表明结论是稳健的。因此,进一步优化社会统筹账户有利于减小收入不平等。     

论行政听证程序的适用范围——以《烟草专卖行政处罚程序规定》的相关规定为中心

行政听证在我国已得到较为广泛的运用。听证程序的适用范围是听证发挥公平公正作用的关键所在,《行政处罚法》对此范围的规定明显过窄,不利于当事人利益的维护。《烟草专卖行政处罚程序规定》虽然适当扩大了其范围,具有积极意义,但依然没有实质性的突破,有待进一步完善。

Do analysts follow emerging economy firms with higher intangible assets? Empirical evidence from Egypt

This paper tests whether analyst coverage and effort are related to the level of intangible assets reported by Egyptian listed firms. Intangible assets represent increasingly important investments for many firms, but most of these assets are not capitalized under prevailing accounting standards. Analysts reduce the information asymmetry by examining both financial reports and other information. Many Egyptian firms today seek access to foreign capital. I hypothesize that the larger the potential intangible assets of firms the more analysts will cover these firms and pursue private information about these firms. Sample consists of 435 firm-year observations over the period 1999–2007, and intangible assets are measured using eight different firm- and industry-level proxies. Consistent with prior research, results suggest that coverage is significantly associated with firm R&D, industry advertising expenses, firm size, and trading volume. Results also suggest that analyst effort is a function of firm and industry-level R&D expenses and firm size.
