The use of earnings and operations management to avoid credit rating downgrades

Firms placed on negative credit watch face the threat of a credit rating downgrade. At the same time, they are given the opportunity to put recovery efforts in place to retain their current credit rating. In this paper, we test to what extent firms use earnings management as a short-term recovery strategy. We find that both accruals-based and real earnings management are associated with firms avoiding credit rating downgrades, and that these alternative earnings management strategies tend to be complements rather than substitutes. However, following the passage of the Sarbanes–Oxley Act, only real earnings management is significantly associated with the credit watch outcome. We find evidence that firms which maintain their rating via earnings management are better able to afford the inevitable earnings reversals, and that in the year following the credit watch period, the credit rating performance of these firms is significantly better than firms which undergo a downgrade, with fewer downgrades and more upgrades in this period. Our results also imply that credit rating agencies are not misled by earnings management but rather allow for some discretion in reporting earnings that facilitates the dissemination of private information about future firm performance.

企业异质性、出口对工资溢价的影响——基于中国工业企业微观数据的经验证据

本文以企业异质性理论为基础,揭示了企业异质性、出口对工资溢价的影响机理。基于中国工业企业微观数据,对企业异质性、出口对工资溢价的影响进行了实证检验。研究结果表明：(1)企业异质性对工资溢价有显著的影响。其中企业创新能力、企业生产率、资本密集度与技术密集度、企业绩效对工资溢价有显著的正向影响,企业创新能力越强、生产率水平越高、绩效越好,其工资溢价越明显。(2)出口、出口补贴能够带来显著的工资溢价,工资溢价与出口密集度、出口补贴强度呈倒U型关系。(3)人力资本(员工受教育水平、职称、技能)对工资溢价有显著的正向影响。人力资本水平越高,其工资溢价越明显。此外,大型企业、中央直属企业、外资企业、沿海企业均存在明显的工资溢价。这一研究结果有着重要的政策启示。     

Corruption and cross-border investment by multinational firms

Motivated by previous studies on the effect of corruption on foreign direct investment, we examine the impact of a distance measure of corruption between host and source countries on cross-border direct investment and find that corruption distance deters cross-border investment. The evidence indicates that corruption distance is not as serious a deterrent of outward direct investment from more-corrupt countries as it is from less-corrupt countries. We conclude that multinational firms with the capacity to engage in bribery can disregard this activity in transparent environments, whereas multinational firms accustomed to operating in transparent environments find it difficult to overcome the administrative complexities in corrupt environments.

Trajectories of Russian manufacturing firms’ growth after the global financial crisis of 2008–2009: the role of restructuring efforts and regional institutional environment

The aim of this article is to conduct an empirical investigation and reveal which types of modernisation strategies and characteristics of regional institutional environment are likely to be associated with patterns of the performance of Russian manufacturing firms in 2007–2012. In addition to estimating the impact of ex-ante behaviour on the rate of sales growth, we use hierarchical cluster analysis to reveal the typical trajectories of firms’ sales growth. We find that the dynamic of sales for more than 90% of firms can be described by just two types of performance curve: (a) crisis decline with recovery and growth; and (b) crisis decline with weak recovery and stagnation. Firms that invested more prior to the crisis and implemented active restructuring were more likely to have positive post-crisis dynamics of sales. We find evidence that firms in the regions with lower levels of corruption (both administrative and everyday) were more likely to recover successfully after the crisis.     

双元学习与先前经验及其交互效应对科技创业企业成长的影响

基于组织学习和企业成长理论,利用来自科技创业企业的问卷数据,构建了回归模型实证分析组织学习、先前经验对科技创业企业成长的影响。结果显示:探索式学习与利用式学习各自会对科技创业企业的成长产生影响,但同时开展两者对科技创业企业成长的影响并不显著;引入先前经验后,双元学习对企业成长的正向作用显著提升。建议科技创业企业在成长中采取顺序双元学习模式,且应做好先前经验与学习方式的合理匹配。     

Book‐to‐Market Equity,Asset Correlations and the Basel Capital Requirement

This paper examines the effect of book‐to‐market equity (BE/ME) on asset correlations under the Basel capital requirement. We find that BE/ME captures variations in asset correlations after controlling for firm size, default probability and industry effects from 1987 to 2011. Obligors with higher BE/ME exhibit lower asset correlations compared to those with lower BE/ME. Decomposing BE/ME into assets‐in‐place and growth options based on the asset pricing literature shows that obligors with more assets‐in‐place or more fixed assets have higher BE/ME and lower asset correlations than those with more growth options. Overall, our findings suggest that BE/ME is an additional important factor that may improve the estimates of asset correlations and thereby banks’ capital adequacy.     

Scope versus speed: Team diversity,leader experience,and patenting outcomes for firms

Research Summary: How does the organization of patenting activity affect a firm's patenting outcomes? We investigate how the composition of patenting teams relates to both the scope of their patent applications and the speed with which their patents are approved, by examining the main effects of team members’ intra‐organizational diversity (based on affiliations with formal organizational units and informal organizational communities) and the moderating effects of team leader experience. We test our moderated mediation model in a sample of 121 teams that filed patents in a Fortune 50 company's India R&D center between 2005 and 2015, using proprietary employee data combined with newly released micro‐data from the U.S Patent and Trademark Office (USPTO). Our findings illuminate the micro‐foundations of innovation in firms by highlighting a trade‐off between organizing patenting activity to maximize scope versus speed. Managerial Summary: Patenting is an important strategic tool that firms can use to protect and create value from their innovations. A firm can benefit from filing a patent application that gives it a wider possible set of claims related to an innovation. It can also benefit from faster approval of a patent application by the Patent Office. However, our study shows that there is a trade‐off between patent application scope and patent approval speed, which creates tensions for the organization of patenting activities inside firms. In particular, we find that the diversity of a patenting team is positively related to patent scope but negatively related to patenting speed, and that these relationships vary with the experience of the team leader.     

Trend in aggregate idiosyncratic volatility

We suggest that price interaction among stocks is an important determinant of idiosyncratic volatility. We demonstrate that as more (less) stocks are listed in the markets, price interaction among stocks increases (decreases), and hence stocks, on average, become more (less) volatile. Our results show that price interaction has a significant positive effect of idiosyncratic volatility. The results of various robustness checks indicate that the effect of price interaction is still significant to the presence of liquidity, newly listed firms, cash flow variables, business cycle variables, and market volatility. Once the price interaction effect is taken into account, no trend remains in idiosyncratic volatility. We conclude that there is no trend, but a reflection of the positive effect of price interaction on idiosyncratic volatility.
