Audit committee chairman characteristics and corporate performance: Empirical evidence from Saudi Arabia

The purpose of this paper is to investigate the impact of corporate governance (CG) characteristics, specifically audit committee chairman (ACC) characteristics. (tenure, expertise, and directorship) on corporate performance (CP). The study was executed on 44 firms, which were registered under the finance sector at Bursa Saudi Arabia. In terms of its scope, the study stretched over quite a long period of time and observed a considerable number of firms; more specifically, it lasted from 2015 to 2019, and observed 195 firms. The relationship between the characteristics of audit committee (AC) directors and CP has been studied extensively in the past. Nevertheless, few studies have investigated the ACC's characteristics. To the best of the researcher's knowledge, no study has yet studied the effect of CG's characteristics, specifically, the ACC characteristics on CP. The study’s conclusions indicate that corporate governance (CG) characteristics, specifically audit committee chairman (ACC) characteristics (tenure and expertise) are positively related to the performance of finance companies. However, the audit committee chairman’s multiple directorships, on the other hand, has no relationship with corporate performance. Review of literature on the audit committee chairman characteristics used in this study is offered, the practical implications and the recommendations for future research works is also emphasized.

Blockchain for Transformation in Digital Marketing

Today, an increasing number of firms are embracing blockchain as part of their efforts to achieve operational efficiency and improve performance, thereby acting as a catalyst to bring about digital transformation. Gartner listed blockchain as the most promising technology in digital marketing in the year 2019. Blockchain is driving digital transformation by forcing organizations to rethink how they operate, in terms of identifying ineffectiveness of traditional approaches to doing business, to address their business needs, promote innovation, and through establishment of standard frameworks. Blockchain shows massive disruption potential in the area of customer relationship management and enhancing consumer experience, besides improving trust, security, and privacy. Therefore, this chapter focuses on providing an enlightenment on how blockchain can specifically address the areas of transformation in digital marketing, prominent frameworks in use, and listing the benefits and challenges of implementing this technology.

Competition and Innovation in Markets with Technology Leaders

In this article, we consider technology leaders (which are innovators) and technology followers (which are non-innovators) to provide a new theoretical explanation for the well-cited empirical evidence of an inverted-U relationship between competition and aggregate innovation. We consider a two-stage game with a deterministic Research and Development (R&D) process, where the leaders first determine their R&D investments simultaneously and then all leaders and followers determine their outputs simultaneously. We show that the inverted-U relationship between competition and aggregate innovation occurs if competition is affected by the number of technology followers. However, the presence of more technology leaders decreases individual R&D investments while increasing aggregate R&D investments. If the total number of firms remains the same but the composition of technology leaders and followers changes in favor of leaders (followers), individual R&D investments decrease (increase) but aggregate R&D investments increase (decrease). The relationship between competition and R&D investments can be U-shaped if the intensity of competition is measured by product substitutability. Contrary to the standard expectation, the presence of more firms may reduce welfare.

Modifying Transactional Databases to Hide Sensitive Association Rules

Although firms recognize the value in sharing data with supply chain partners, many remain reluctant to share for fear of sensitive information potentially making its way to competitors. Approaches that can help hide sensitive information could alleviate such concerns and increase the number of firms that are willing to share. Sensitive information in transactional databases often manifests itself in the form of association rules. The sensitive association rules can be concealed by altering transactions so that they remain hidden when the data are mined by the partner. The problem of hiding these rules in the data are computationally difficult (NP-hard), and extant approaches are all heuristic in nature. To our knowledge, this is the first paper that introduces the problem as a nonlinear integer formulation to hide the sensitive association rule while minimizing the alterations needed in the data set. We apply transformations that linearize the constraints and derive various results that help reduce the size of the problem to be solved. Our results show that although the nonlinear integer formulations are not practical, the linearizations and problem-reduction steps make a significant impact on solvability and solution time. This approach mitigates potential risks associated with sharing and should increase data sharing among supply chain partners.

A tractable multi-leader multi-follower peak-load-pricing model with strategic interaction

While single-level Nash equilibrium problems are quite well understood nowadays, less is known about multi-leader multi-follower games. However, these have important applications, e.g., in the analysis of electricity and gas markets, where often a limited number of firms interacts on various subsequent markets. In this paper, we consider a special class of two-level multi-leader multi-follower games that can be applied, e.g., to model strategic booking decisions in the European entry-exit gas market. For this nontrivial class of games, we develop a solution algorithm that is able to compute the complete set of Nash equilibria instead of just individual solutions or a bigger set of stationary points. Additionally, we prove that for this class of games, the solution set is finite and provide examples for instances without any Nash equilibria in pure strategies. We apply the algorithm to a case study in which we compute strategic booking and nomination decisions in a model of the European entry-exit gas market system. Finally, we use our algorithm to provide a publicly available test library for the considered class of multi-leader multi-follower games. This library contains problem instances with different economic and mathematical properties so that other researchers in the field can test and benchmark newly developed methods for this challenging class of problems.

Compliance Behaviour of New Zealand Exporters with Best Practices of Supply Chain Security

<p>Uninterrupted growth of international trade and the constant threats to global supply chains have led to the emergence of numerous voluntary compliance guidelines based on standards and compliance. Initiatives, such as, the Authorised Economic Operators is the result of the global efforts to facilitate, prevent and secure international trade against cross-border crime. The Authorised Economic Operator is an initiative of the World Customs Organisation and its member countries. Its core philosophy is developing public to private partnerships for the safety of international trade and trade facilitation. These initiatives are growing in scope with a variety of programmes developed by governments. The objective of these programmes is encouraging an ethos of voluntary compliance based on standards, best practices and self-governance. Certified firms can obtain a trusted trader status and cross-border benefits when they demonstrate that their supply chain is secure. New Zealand has its own programme called the Secure Export Scheme. While this programme is voluntary in nature, firms entering the programme are required to adopt, maintain, and comply with the standards of security for their supply chain. This thesis investigates the compliance behaviour of New Zealand exporters with the standards of security of the Secure Export Scheme. The Authorised Economic Programme is a new concept, and while there is scholarly research of other types of voluntary standards, research in this particular area is minimal. To the best of the researcher’s knowledge, this is one of the first studies to examine the compliance behaviour of firms that have been part of the programme since inception. Accordingly, this study is guided by the various views of the compliance theory and proffers a conceptual framework to delineate the different actors and factors that influence firms’ compliance behaviour. The study measured compliance and non-compliance of firms to understand the underlying patterns with specific best practices. This study contributes towards our current understanding of compliance behaviour. While, overall, the compliance of the New Zealand exporters with the best practices is high, there are some areas of concern. The study further identified that a number of firms were not compliant with certain best practices. This finding indicates that other factors, such as, the way the governing body presents its written requirements might influence the compliance behaviour with those specific best practices. The conceptual model proposed in this study lays the foundation for further research seeking to probe compliance behaviour of Authorised Economic Operators.</p>

Private or Public Equity? The Evolving Entrepreneurial Finance Landscape

The U.S. entrepreneurial finance market has changed dramatically over the last two decades. Entrepreneurs raising their first round of venture capital retain 30% more equity in their firm and are more likely to control their board of directors. Late-stage startups are raising larger amounts of capital in the private markets from a growing pool of traditional and new investors. These private market changes have coincided with a sharp decline in the number of firms going public--and when firms do go public, they are older and have raised more private capital. To understand these facts, we provide a systematic description of the differences between private and public firms. Next, we review several regulatory, technological, and competitive changes affecting both startups and investors that reveal how the trade-offs between going public and staying private have changed. We conclude by listing several open research questions.

Is Industry Size a Carrier for Wage Inequality? A Panel Study Addressing Independent Variables of Inherently Different Sizes across Units

We address how independent variables of inherently different sizes across units, e.g., small vs. large industries, in panel regression is an advantage interpretively. Analyzing a Norwegian industry panel, we find that wage inequality is a function of industry size, particularly size increase, in an absolute number of firms. A possible reason is that specialized skilled employees negotiate higher wages when there are many legal entities. The findings can also imply that wage inequality is more sensitive to random change, particularly an increase, in large rather than small industries. We conclude that particularly large industries are positive carriers of wage inequality and discuss potential underlying causal mechanisms such as monopolistic competition.

A Note on the Existence of the Competitive Equilibrium in Grossman and Shapiro (1984)

In their seminal paper, Grossman, G. M., and C. Shapiro. 1984. “Informative Advertising with Differentiated Products.” The Review of Economic Studies 51: 63–81 assume that it is not profitable for a firm to deviate to the supercompetitive price of Salop, S. C. 1979. “Monopolistic Competition with outside Goods.” The Bell Journal of Economics 10: 141–56. In this note, it is shown that this assumption is violated if, roughly, each firm reaches less than half of all consumers unless it is a duopoly. This implies that most of the simulations in Grossman, G. M., and C. Shapiro. 1984. “Informative Advertising with Differentiated Products.” The Review of Economic Studies 51: 63–81 are not actually equilibria. More importantly, this implies that for their equilibrium to exist nearly all consumers must receive at least one ad. For example, with just four firms in the market, at least 96% of the consumers must receive at least one ad, and this percentage increases with the number of firms in the market.
