Material weakness disclosures and restatement announcements: The joint and order effects

We examine differences in stock price, option volatility, and litigation reactions to restatement announcements that are associated with a material weakness (MW) disclosure. Contrasted with restatements that are not associated with any MW disclosure, our analyses reveal that firms that announce both a restatement and an associated MW experience significantly more negative market returns, greater implied volatility, and higher likelihood of class action lawsuits. Separating the restatements into timely reporters, where the MW precedes the restatement, and non‐timely reporters, where the MW is concurrent with or follows the restatement, we find that timely reporters experience more negative returns at the time of the restatement, relative to non‐timely reporters, suggesting that investors perceive the early MW disclosure to signal more pervasive control‐related problems. Interestingly, we find that timely and non‐timely reporters are equally likely to be sued, consistent with the argument that wrongdoing (through either a timely or non‐timely MW disclosure) provides stronger grounds for establishing scienter. However, timely reporters appear to secure more favorable litigation outcomes: they face higher likelihood of lawsuit dismissals and pay much lower settlements, compared to non‐timely reporters. Overall, our evidence provides new insights into how market participants incorporate information about internal control weaknesses into their perceptions regarding the economic implications of financial restatements, and financial reporting quality.     

Corporate Social Responsibility: Its Economic Impact and Link to the Bullwhip Effect

This paper examines the economic impact of implementing Corporate Social Responsibility (CSR) in the supply chain operations of multinational corporations (MNC). Because they have global supply chains in emerging markets, MNCs face certain operational challenges. For example, unethical operations often result in a huge loss to MNCs in the long run, even though their initial cost seems to be low. In this paper, we extend the Bullwhip Effect theory in supply chain management to the ethical operations context, and define and evaluate a special Bullwhip Effect due to Unethical Operations (BEUO). Using economic data from various sources including Ford, Toyota, and GM in the auto industry, we first estimate the indices of BEUO for the three companies and demonstrate the economic necessity for MNCs to incorporate CSR with supply chain operations. We then propose a coherent approach, blending what we term the bottom-up and proactive methods, to achieve such an outcome. The bottom-up approach requires MNCs to switch their focus on stakeholders, shifting from shareholders to consumers and workers, and on decision levels from public relationships to supply chain operations. The proactive approach recommends initializing specific CSR operations to mitigate the negative impact of BEUO. Both theoretical analysis and case studies are conducted to evaluate our developed propositions that MNCs adopting the proposed CSR operations will in the long run achieve better economic performance. Recommended actions for implementation, based on best practices, are also presented.     

Ordering univariate distributions by entropy and variance

This paper examines the role of variance and entropy in ordering distributions and random prospects. There is no universal relation between entropy and variance orderings of distributions. But we place their relationship in the context of a stronger ordering relation known as dispersion ordering. Further, some conditions are identified under which variance and entropy order similarly when continuous variables are transformed. We also analyze parametric changes which do not disturb the agreement between these rankings. The results are conveniently tabulated in terms of distribution parameters.     

Receiving,Recording, and Responding to Customer Complaints: The Effects of Formalizing Customer Complaint Handling Policies in Retail Firms

ABSTRACT

Given the critical need for retail firms to provide high quality customer service and satisfaction, this article investigates the importance of formalizing customer complaint handling policies and procedures with regard to its relationship to the ways in which retail companies receive, record, and respond to customer complaints. A survey of 184 firms from the retail environment of a midsized community reveals that the existence of such formalized procedures is significantly associated with firm size, better channels of communication with customers, mechanisms of recording customer feedback, and better-trained employees, which have been shown to relate to higher firm performance.     

Modeling the dependence structure between default risk premium,equity return volatility and the jump risk: Evidence from a financial crisis

This paper investigates the dependence structure between default risk premium, equity return volatility and jump risk in the equity market before and during the subprime crisis. Using iTraxx CDS index spreads from Japanese and Australian markets, the paper models the different relationships that can exist in different ranges of behavior. We consider several Archimedean copula models with different tail dependence structures, namely, Gumbel, Clayton, Frank, AMH and Joe copulas. Although the dramatic change in the levels of the iTraxx CDS index, we find strong evidence that the dependence structure between CDS and stock market conditions is asymmetric and orienting toward the upper side. In addition, we find that the Japanese CDS market is more sensitive to the stock return volatility than the jump risk and the magnitude of this sensitivity is related to the market circumstances. However, Australian CDS market is more sensitive to the jump risk than stock return volatility before and during the financial crisis. This result has important implications for both global financial stability and default risk management. Specifically, the heterogeneity of markets, coupled with the diversity in the risk exposures cause the default risk premium and equity markets to exhibit different levels of sensitivity.     

Curriculum Internationalization at AACSB Schools: Immersive Experiences,Student Placement,and Assessment

This article presents results from a survey of AACSB-accredited business schools’ progress in internationalizing their curricula in view of a recent AACSB report. We present data on the use of immersive experiences, degree of success in student placement in internationally oriented careers, and assessment of internationalization efforts. The results indicate growth of internationalization activities at virtually all schools as expected, but these efforts may not always match AACSB recommendations. For instance, AACSB criticized business programs for not coordinating internationalization activities in a strategic manner to improve courses and develop skills needed by international managers. Our survey finds that many schools do not attempt to tie their international experiences to specific courses, but they report the experiences are used to build skills students need. Most institutions also do not examine job placement as a measure of curriculum internationalization success. We find that many schools do not assess the outcomes of their internationalization efforts in a way that can demonstrate whether or not recent AACSB suggestions are being met.     

Islamic Corporate Governance: Risk-Sharing and Islamic Preferred Shares

The recent financial crises (including the Asian and subprime crises) indicated the need to reinforce corporate governance mechanisms in emerging and developing market economies. Corporate governance refers to all the factors that affect firm processes (including, among others, financing strategies). Firms must avoid debt financing instruments and adopt financing instruments that allow for “risk-sharing” rather than “risk-shifting” because all recent financial crises were, in essence, debt crises. The primary objective of this paper is to examine the principles of risk-sharing promoted by Islamic finance and study their implications for corporate governance. The secondary objective of this paper is to propose a pricing model for a new risk-sharing financial instrument (Islamic preferred shares, IPS) that was recently discussed by Zarka and Al-Suhaibani (Shariah-compatible preference shares: The Sharia Basis and Economic Rationale. Working paper, SABIC Chair for Islamic Financial Market Studies, 2012). We study the implications of this new instrument as a powerful tool for corporate governance in the case of Islamic markets. We explain the possible contribution of IPS to agency cost reduction, Sharia screening costs and ethical corporate governance.     

Incorporating location,routing and inventory decisions in supply chain network design

This paper for the first time presents a novel model to simultaneously optimize location, allocation, capacity, inventory, and routing decisions in a stochastic supply chain system. Each customer’s demand is uncertain and follows a normal distribution, and each distribution center maintains a certain amount of safety stock. To solve the model, first we present an exact solution method by casting the problem as a mixed integer convex program, and then we establish a heuristic method based on a hybridization of Tabu Search and Simulated Annealing. The results show that the proposed heuristic is considerably efficient and effective for a broad range of problem sizes.
