The relationship between risk-neutral and actual default probabilities: the credit risk premium

The study investigates empirically the relationship between the risk-neutral measure Q and the real-world measure P. We study the ratio between the risk-neutral and actual default intensities, which we call the coverage ratio or the relative credit risk premium. Actual default intensities are derived from rating agencies annual transition matrices, while risk-neutral default intensities are bootstrapped from CDS quotes of European corporates. We quantify the average risk premium and its changes over time. Compared to related literature, special attention is given to the effects of the recent financial and European sovereign crises. We find that average credit risk premia rose substantially and that post-crisis levels are still higher than those observed before the financial crisis. This observation is especially true for high-quality debt and if it persists, it will have an impact on corporates funding costs. The quantification and revision of risk premia contributes to the discussion of the credit spread puzzle and could give extra insights in valuation models that start from real-world estimates. Our work is furthermore important in the context of state aid assessment. The real economic value (REV) methodology, applied by the European Commission to evaluate impaired portfolios, is based on a long-term average risk premium.     

Hedging performance of multiscale hedge ratios

In this study, the wavelet multiscale model is applied to selected assets to hedge time-dependent exposure of an agent with a preference for a certain hedging horizon. Based on the in-sample and out-of-sample portfolio variances, the wavelet-based generalized autoregressive conditional heteroskedasticity (GARCH) model produces the lowest variances. From a utility standpoint, wavelet networks combined with GARCH have the highest utility. Finally, the wavelet-GARCH model has the lowest minimum capital risk requirements. Overall, the wavelet GARCH and wavelet networks offer improvements over traditional hedging models.     

Ownership effects among Native American banks, 2001-2016

Minority Depository Institutions (MDIs), including Native American Banks (NatBs), play an integral role in providing financial services to the under-served. NatBs are split between those that are Tribal owned and those owned by individual Native Americans as private banks. This research explores differences between the two, other MDIs and comparable mainstream banks, using data from 2001 to 2016. Tribal NatBs are hypothesized to emphasize community development for the under-served over profit maximization, and to take on high levels of risk. Testing uses comparisons of population means and regressions, and the overall pattern of results and limited regression findings support those possibilities.

Rank and file equity compensation and earnings management: Evidence from stock options

The widespread use of rank and file equity‐based compensation suggests that executives believe that rank and file employees can affect firm outcomes, and some research supports this view. If equity‐based incentives influence rank and file employees’ productive efforts, they might also influence their earnings management decisions. We find that increases in rank and file employees’ option‐based compensation—our proxy for equity‐based compensation—are associated with increases in earnings management and that this relation is attributable to real activities (as opposed to accrual) earnings management. Cross‐sectional tests indicate that the relation is stronger when rank and file option compensation is likely to generate greater performance incentives and attenuated in the presence of more intense monitoring. Finally, we explore the role of cash constraints and overvaluation as potential alternative explanations for this relation and find that neither accounts for our results.     

个人大股东持股与股价暴跌风险

本文以2007至2016年中国A股上市公司为样本,考察了个人大股东持股与股价暴跌风险之间的关系。研究发现:第一,个人大股东持股比例的增加能够显著降低公司未来股价暴跌风险。这一结论在剔除了个人大股东中董监高持股数量、进行内生性处理、更换不同统计检验方法后依然成立。第二,个人大股东持股对公司管理层监督的效果并不明显,个人大股东持股比例的增加对于公司应计盈余管理、真实盈余管理、投资效率、过度投资等可能影响公司股价暴跌风险的经营指标并没有显著影响。第三,个人大股东的持股加强了公司股权制衡的力度,进而显著降低了公司股价暴跌风险。股权制衡机制解释了大股东持股对股价暴跌风险一半以上的影响。本文的研究对于全面认识个人大股东在资本市场中发挥的作用,促进股市平稳发展具有重要的理论和现实意义。     

Decomposing the accrual premium: The evidence from two markets

We decompose the accrual premium and study its components in the debt and equity markets. We show that the importance of each accrual component depends on the sample and the type of market considered. The short‐term accruals component is primarily observed in equity markets, among small and young companies, which is consistent with mispricing arguments. The long‐term accruals premium is consistently positive and significant in different samples and markets. This component reflects growth in capital expenditures, and it is counter‐cyclical and predictable, which is in line with investment‐based explanations. Finally, the financial accruals component does not generate predictability.     

The role of technology-based services in establishing brand equity within the private hospitals sector in Kuwait

This study aims to explore the role of technology-based services in establishing brand equity within the private hospitals sector in Kuwait. A survey is designed based on dimensions that include ease of use, e-responsiveness, e-scape, security, and customization. E-responsiveness and security had strong and direct influence on brand equity; whereas, ease of use, e-escape, and customization had no significant positive impact on the brand equity. The proposed model of relationship between e-service quality and brand equity has the potential to help hospital managers to establish their brand equity through managing the level of their online services.     

The interaction effect of mobile phone screen and product orientation on perceived product size

Perceived product size is a key concern in online retail, particularly in fashion and grocery. The screen on which consumers view a product (e.g., desktop or mobile) might constitute a frame that biases size perception, on the basis of assimilation and contrast effects (pool and store theory). The rise of mobile commerce exacerbates this issue, as framing effects might be stronger versus desktop settings as screens are smaller. Further, as mobile phone's screen orientation varies situationally (vertical vs. horizontal), the perceived product size might vary, depending on the interaction of screen and product orientation. By introducing the framing ratio as a means to predict extent, dimensionality and symmetry of size biases, we generalize specific findings from extant research. Empirically, four experimental studies demonstrate that contextual frames (i.e., vertical vs. horizontal screens) and product orientation (e.g., jeans vs. shoes) interact to bias the size perception, in that sizes are overestimated on the dimension that approaches the frame (high framing ratio), compared with conditions where the frame is distant (low framing ratio). If product size is misperceived, willingness to pay might be affected (e.g., for groceries). Thus, size perceptions have a direct impact on managerially relevant variables.     

Corporate social responsibility in the tourism industry: evidence from seasoned equity offerings

This study examines the impact of corporate social responsibility (CSR) in the tourism industry using seasoned equity offerings (SEOs) from 1992 to 2015. We show that tourism SEO issuers engaging in CSR activities experience less negative market reactions to SEO announcements. The findings also reveal that the negative reactions around SEO announcements are significantly lessened for tourism firms with better CSR performance in the context of high information asymmetry, because such activities serve as an ethical commitment to outside investors, and thus align the interests between SEO issuers and outside investors, which eventually mitigates negative market reactions to SEO announcements. Overall, these results indicate that tourism issuers with better CSR performance are able to reduce the agency costs and adverse selection problem for uninformed investors in the process of issuing SEOs.
