Intraday volume and volatility relations with and without public news

This paper reexamines the dynamic relation between intraday trading volume and return volatility of large and small NYSE stocks in two partitioned samples, with and without identifiable public news. We argue that the sequential information arrival hypothesis (SIAH) can be tested only in periods containing public news. After partitioning the sample into periods with and without public news, we find bi-directional Granger-causality between volume and volatility in the presence of public information as hypothesized by the SIAH. Our analysis further suggests that return volatility is higher in the periods with public news, while trading volume is significantly higher in the no-news period; perhaps owing to the importance of private information for trading stocks. Using the sample without public news, we find evidence that volume Granger-causes volatility without feedback. These results are broadly consistent with behavioral models like the overconfidence and biased self-attribution model of [Daniel, K., Hirshleifer, D., Subrahmanyam, A., 1998. Investor psychology and security market under- and over-reactions. Journal of Finance 53, 1839–1885]. It appears that overconfident investors overrate the precision of their private news signals and therefore trade too aggressively in the absence of public news; when public news arrives, investors’ biased self-attribution triggers excessive return volatility.     

You May Not Reap What You Sow: How Employees’ Moral Awareness Minimizes Ethical Leadership’s Positive Impact on Workplace Deviance

Although a growing body of research has shown the positive impact of ethical leadership on workplace deviance, questions remain as to whether its benefits are consistent across all situations. In this investigation, we explore an important boundary condition of ethical leadership by exploring how employees’ moral awareness may lessen the need for ethical leadership. Drawing on substitutes for leadership theory, we suggest that when individuals already possess a heightened level of moral awareness, ethical leadership’s role in reducing deviant actions may be reduced. However, when individuals lack this strong moral disposition, ethical leadership may be instrumental in inspiring them to reduce their deviant actions. To enhance the external validity and generalizability of our findings, the current research used two large field samples of working professionals in both Turkey and the USA. Results suggest that ethical leadership’s positive influence on workplace deviance is dependent upon the individual’s moral awareness—helpful for those employees whose moral awareness is low, but not high. Thus, our investigation helps to build theory around the contingencies of ethical leadership and the specific audience for whom it may be more (or less) influential.     

Experience, information asymmetry, and rational forecast bias

This study examines whether it is ever rational for analysts to post biased estimates and how information asymmetry and analyst experience factor into the decision. Using a construct where analysts wish to minimize their forecasting error, we model forecasted earnings when analysts combine private information with consensus estimates to determine the optimal forecast bias, i.e., the deviation from the consensus. We show that the analyst??s rational bias increases with information asymmetry, but is concavely related with experience. Novice analysts post estimates similar to the consensus but as they become more experienced and develop private information channels, their estimates become biased and deviated from the consensus. Highly seasoned analysts, who have superior analytical skills and valuable relationships, need not post biased forecasts.     

Effectiveness and Efficiency of Cross-Border Knowledge Transfer: An Empirical Examination

abstract    Based on a sample of 102 US organizations, this study examines the impact of knowledge characteristics, recipient learning intent, source attractiveness, and relationship quality on the effectiveness and efficiency of knowledge transfer from the international business affiliates of these organizations. Findings indicate that recipient learning intent and source attractiveness positively impact the effectiveness of knowledge transfer. In addition, recipient learning intent was found to have a positive effect on knowledge transfer efficiency. In particular, results highlight the strong positive impact that the quality of the relationship between the source and the recipient has on both the efficiency and effectiveness of cross-border knowledge transfer. The study also indicates that knowledge value is positively associated with recipient learning intent and that knowledge value, rarity and non-substitutability influence source attractiveness. Finally, findings suggest that the relationship between knowledge characteristics and knowledge transfer is partially mediated by recipient learning intent and source attractiveness.     

Does Bank Diversification Improve Output Growth? Evidence from the Recent Global Crisis

This study examines whether the diversity of activities conducted by the banking sector in the years approaching the recent global financial crisis alleviated the adverse impact of the crisis. Using data for 28 industries in 66 countries, we find that bank diversification has strengthened country resilience to the crisis, as measured by industry growth over the period 2008–2009. However, we find that while both bank‐based and market‐based economies have been affected negatively by the crisis, the contribution of bank diversification in mitigating the real impact of the crisis is pronounced only in bank‐based economies. Overall, our findings suggest that countries with significant bank diversification have also been the most resilient to the recent global crisis.     

Determinants of consumers’ intentions to use smartphones apps for flight ticket bookings

This study examines customers’ adoption and acceptance of smartphone apps to book their flight tickets. By integrating customers’ innovativeness, involvement and perceived trust as additional variables, this study extends the Unified Theory of Acceptance and Use of Technology (UTAUT) and proposes a theoretical model that includes seven explanatory variables of the customers’ behavioural intentions: performance expectancy, effort expectancy, social influence, facilitating conditions, customers’ innovativeness, customers’ involvement and perceived trust. Data were collected from 369 customers who had booked their flight tickets via smartphone apps and was further analysed by employing partial least squares (PLS). Findings suggest that performance expectancy, facilitating conditions, customer innovativeness and perceived trust are positive and significant determinants of customers’ intentions to book their flight tickets on smartphone apps. Accordingly, several important implications for academics and industry decision makers are formulated.     

Intellectual capital reporting practices in an Islamic bank: A case study

Given the nature and importance of Islamic banks in recent times, we can expect them to have significant intellectual capital anchored in their Sharia‐based knowledge and expertise. However, we know very little or nothing about how and why intellectual capital‐related information is provided in their corporate reports. We fill this gap in our existing knowledge of the field with a view to enhance relevant literature. As far as we know, this article is one of the earliest exploratory attempts to examine intellectual capital reporting practices of an Islamic bank. We have undertaken a longitudinal (2001–2015) case study related to the intellectual capital reporting practices of an Islamic bank. Key results include significant rise of intellectual capital reporting over time, dominance of internal capital‐related items in intellectual capital reporting profile and the dynamics of changes in intellectual capital reporting practices over time. Through an institutional theory lens, we explain that this is due to the changes in the external institutional environment and various intra‐organisational factors such as strong ethical culture, unique knowledge base (Sharia), and corporate governance regime.

The Causes and Consequences of Accelerated Stock Repurchases

We examine the choice between accelerated share repurchase (ASR) and open market repurchase (OMR) as repurchase mechanisms between 2004 and 2007. For a sample of ASRs and OMRs that actually buy shares in the announcement quarter, we find that ASR firms have lower market‐to‐book ratios, less cash, but greater managerial entrenchment. Prior to repurchase, ASR firms are subject to significantly more takeover rumors than OMR firms are, and this, along with entrenchment and undervaluation, affects the choice to use ASRs. ASR firms experience positive average abnormal returns both before and after the announcement. Moreover, the latent takeover probability is significantly lower for both ASR and OMR firms (when compared with pre‐announcement levels), but the reduction for ASR firms is more pronounced. Our results suggest that repurchases, and especially ASRs, indeed make a firm a less attractive prospect for takeover.     

Shadow Banking Credit Intermediation： Determinants of Default Risks in Securitization and Collateralization

The growth in shadow banking system over the past few years is acknowledged as the key risk to Malaysia＇s financial stability. This is because that it is associated with growth in the household debts extended by the shadow banks. In line with initiatives by the Bank Negara Malaysia （the Central Bank of Malaysia） to enhance surveillance on the activities of the shadow banks in Malaysia, this study attempts to examine the determinants of default risks of shadow banks restricting to focus on their two main activities： securitization and collateralization. The results provide empirical evidence that future methodology to examine the systemic risks in the shadow banking system may need to account for additional explanatory variables that measure collateralized assets that are being intermediated.
