THE IMPACT OF THE INSIDER TRADING SCANDAL ON THE INFORMATION CONTENT OF THE WALL STREET JOURNAL'S “HEARD ON THE STREET” COLUMN

We examine the impact of a scandal on the information content in the “Heard on the Street” column of the Wall Street Journal. Following the scandal in 1984, the column is found to have a reduced impact on stock prices for both buy and sell recommendations. However, the stock price response to information later published in the column before the publication day is smaller for the post-scandal period. This result suggests that after the scandal, editors and authors may have become more cautious in guarding against information leaks in the column. The scandal does not appear to have changed the impact of the column on trading volume.     

The dynamic dependence between stock markets in the greater China economic area: a study based on extreme values and copulas

This study employs the dynamic copula method and extreme value theory to investigate the dependence structure between pairs of greater China economic area (GCEA) stock markets consisting of Shanghai (SHSE), Shenzhen (SZSE), Hong Kong (HKSE), and Taiwan (TWSE) stock exchanges from July 2000 to June 2017. We also examine the impact of financial crisis on the dependence structure by considering the global financial crisis and the Chinese stock market crash (2015–2016). Many studies have shown that the benefits of portfolio diversification across the stock markets in the same region could be diminishing. However, it is interesting to see that the diversification benefits appear to be viable for investing in some GCEA pairs of stock markets (SHSE–TWSE and SZSE–HKSE).     

Journal Rankings,Collaborative Research and Publication Strategies: Evidence from China

Abstract

The primary focus of our paper is on the potential for in-house journal ranking lists to create friction between international collaborating researchers due to differences in how particular journals are rated on different lists. Using a questionnaire distributed to Chinese accounting researchers, we identify a number of potential friction points between Chinese and UK researchers. We find that almost all of our Chinese respondents use their own school's in-house ranking list as the primary or exclusive reference point for assessing journal quality, and 73% of respondents acknowledge that this has caused problems when working with scholars from other universities because of differences in how their institutions rank journals.     

Engineered nanomaterials: risk perception,regulation and insurance

Concerns surrounding the health risk of engineered nanomaterials, effective regulation and the lack of specifically tailored insurance products for the nanotechnology sector are putting the industry’s long-term economic viability at risk. From the perspective of the underwriter, this article speculates on the relationship between risk perception, regulation and insurability. In the nanotechnology sector, regulators are currently failing to keep pace with innovation, and insurers generally lack guiding principles for underwriting occupational risk from nanomaterial exposure. Such vulnerabilities when combined with misguided risk perceptions can lead to the overpricing of risk transfer and ill-conceived regulatory initiatives, thus potentially exhausting resources and stifling innovation in the sector. In the absence of well-developed regulatory protocols, the insurance industry has, and will continue, to occupy a key role as an effective lobby in terms of improved risk management practice. We suggest that the insurance industry will increasingly rely on control banding frameworks and ‘risk mitigation at source’ methods developed in conjunction with their clients to manage severe acute diversifiable risks. Long tail risk will continue to represent a serious challenge to insurers and regulators. In the meantime, insurers will have to bridge their current needs with improvised solutions. As an example of one possible solution, we outline a framework that utilizes financial instruments to hedge an insurer’s exposure to uncertain estimates of these long-term risks.     

Akbar's multiculturalism: lessons for diversity management in the 21st century

This paper challenges the hegemony of US‐centric perspectives in the diversity management literature by explaining how non‐Western histories and cultures may provide alternative contexts for understanding and managing diversity. In pursuit of this, the paper describes how Muslim ruler Jalaluddin Muhammad Akbar conceptualized multiculturalism in 16th century India, and how his principles of sulh‐i‐kul, rah‐i‐aql, and rawa‐i‐rozi may be adopted to develop a sociopolitical environment conducive to managing cultural diversity in organizations, an environment currently lacking even in the majority of democratic countries in the world today.

THE TECHNICAL INEFFICIENCY EFFECTS OF TURKISH BANKS AFTER FINANCIAL LIBERALIZATION

The banking sector in Turkey has grown significantly over the last two decades of financial liberalization. One of the aims of the financial liberalization was to improve efficiency through restructuring programs including the privatization of state banks and the encouragement of mergers. In this paper we identify key factors determining the technical efficiency differentials among Turkish commercial banks in the pre‐ and post‐liberalization periods, using the technical inefficiency effects model. We found that loan quality, size, ownership of the banks, and profitability have a positive and significant impact on the technical efficiencies of banks. The results warrant implementation of effective regulatory measures to improve the quality of the earning assets of commercial banks. Furthermore, steps by the government to encourage acquisitions or mergers for private banks and the privatization of state‐owned banks seem to be consistent in improving the overall efficiency of commercial banking in Turkey.     

Interactive Mining of Strong Friends from Social Networks and Its Applications in E-Commerce

Social networks are generally made of individuals who are linked by some types of interdependencies such as friendship. Most individuals in social networks have many linkages in terms of friends, connections, and/or followers. Among these linkages, some of them are stronger than others. For instance, some friends may be acquaintances of an individual, whereas others may be friends who care about him or her (e.g., who frequently post on his or her wall). In this study, we integrate data mining with social computing to form a social network mining algorithm, which helps the individual distinguish these strong friends from a large number of friends in a specific portion of the social networks in which he or she is interested. Moreover, our mining algorithm allows the individual to interactively change his or her mining parameters. Furthermore, we discuss applications of our social mining algorithm to organizational computing and e-commerce     

Kraft's acquisition of Cadbury: Was it an amicable transatlantic merger or a hostile takeover?

This case‐based research evaluates and discusses Kraft's 2009–2010 acquisition of the UK‐based Cadbury, which turned into a bitter fight and a hostile takeover. As both firms have a rich history and distinct brand identities, the merger came to the attention of the global media and public on both sides of the Atlantic. Drawing on the merger's lengthy negotiations and the two companies' distinctive corporate cultures, this article analyzes the merger and its chaotic negotiations and developments. The merger was opposed in the United Kingdom because of Kraft's harsh approach of targeting an iconic British brand that had been in business for over 150 years. Eventually, both companies did compromise in an amicable manner and concluded a friendly tie‐up. The postmerger period reveals that Kraft's acquisition was a part of its future reorganization and expansion in global markets. This case‐based research also provides academic and practical implications for international business managers as well as multinational corporations.
