Business activity and the environment: The case of Guyana Sugar Corporation and thallium sulphate

Thallium Sulphate is one of the most lethal chemicals known. Its commercial use has been banned in the West and in many Third World countries. However, it recently came to light that the Guyana Sugar Corporation was importing large amounts of the substance and that this has led to acute and chronic poisoning of many Guyanese. This paper examines this case and discusses its ethical implications.Jang B. Singh, B. A. (Toronto), M. A.

Among his research interests are corporate social responsibility and the role of business ethics in the university curriculum. He was born in Guyana.     

The estimates of philanthropic behavior and attitude in South Korea: Methodological consideration

Estimates on philanthropic giving are one of the major topics within nonprofit studies globally. South Korea has engaged in measuring philanthropic behaviors and attitudes since the early 2000s, however, little is known about the validity of the measures that are used to collect giving and volunteering data. This study aims to investigate the methodological matters of the empirical philanthropy datasets in South Korea. A total of nine datasets were identified that measure philanthropic behaviors and attitudes in South Korea. Among the nine datasets, six were used to analyze the methodological matters for the purposes of this study. This article discusses the challenges associated with research methods including definitional challenges, instrument design issues, and other research methodological issues on the identified philanthropic giving datasets in South Korea. Results of this study suggest insights for improving measures of charitable giving and volunteering in South Korea. The findings are significant because differences in approaches to measuring donation behavior produce substantial differences in reported estimates.     

The Determinant of the Hospitality Industry's Unsystematic Risk: A Comparison Between Hotel and Restaurant Firms

ABSTRACT

Unsystematic risk is accepted as an important factor in stock valuation. Despite the importance, little has been done to study the relationship of unsystematic risk to stock values in the hospitality industry. This study attempted to advance the understanding of financial variables that could be related to unsystematic risk of hospitality firms. Regression models were developed for hotel and restaurant firms, using unsystematic risk as the dependent variable and financial variables as independent variables. The major findings of this study indicate: 1) more profitable hospitality companies have less unsystematic risk, 2) reducing reliance on debt financing could reduce unsystematic risk, 3) the positive relationship between operating leverage and unsystematic risk, suggesting that decreasing operating leverage could mitigate the stock price volatility of hospitality firms, and 4) large hotel and restaurant firms have less unsystematic risk than small firms. This study should help management of hospitality firms incorporate effects of shareholder expectations into their operational decision making as an integral part of long-range financial planning.     

Labor unions and post-acquisition integration capability: Evidence from goodwill impairment

We examine whether operating inflexibility posed by labor unions affects goodwill impairment. We predict such inflexibility hinders resource reallocation after acquisition, thereby preventing the acquiring firm from realizing synergies included in goodwill. Consistent with this prediction, we find that the strength of labor unions is positively associated with the likelihood and magnitude of goodwill impairment losses. Our results are robust to a battery of tests that address the potential endogeneity. Furthermore, we find that managers who possess superior ability mitigate the negative consequences of labor unions on goodwill impairment. Overall, our findings suggest that operating inflexibility posed by labor unions is an important determinant of goodwill impairment that indicates a failure to realize the expected synergy from the acquisition.     

How to maintain sustainable consumer behaviours: A systematic review and future research agenda

Maintaining sustainable consumer behaviours is necessary for both mitigating environmental problems and the success of sustainable businesses. However, to date, the focus is mainly on the motivation-adoption link (i.e., how to motivate sustainable consumer behaviours) rather than the adoption-continuance link (i.e., how to maintain those behaviours). This study addresses the link between sustainability adoption and continuance, through a structured literature review. Specifically, this study synthesizes what is (and is not) known about the post-adoption (continuance) stage of the sustainable consumer journey, by reviewing and integrating the results of 87 articles. This review has three key outcomes. First, it elaborates on the importance and distinction of the continuance stage, which is predicted by a set of different and ‘evolving’ factors, compared with motivation and initial adoption. Second, the key components of the continuance stage are identified and grouped under (I) post-adoption cognitive perceptions, (II) emotional outcomes, and (III) subsequent behavioural patterns of (dis)continuance, spillover, advocacy, loyalty and habit formation. Third, this study introduces the concept of sustainable consumer behaviour continuity and discusses theoretical relationships in a conceptual framework. Finally, this review identifies knowledge gaps and provides research directions as well as implications for theory and practice.     

The effect of the Money Market Mutual Fund Liquidity Facility (MMLF) on corporate short-term borrowing costs

In this article, I study the effect of the Money Market Fund Liquidity Facility (MMLF) on corporate short-term borrowing costs. Although MMLF loans accept a broader range of collateral acquired from money market funds (MMFs) than Asset-Backed Commercial Paper Money Market Mutual Fund Liquidity Facility (AMLF) loans, their higher loan rates could make the intervention less effective. I find the average yield has decreased by 20–24 basis points. The yield-decreasing effects of the MMLF are stronger for securities issued by eligible non-US firms, non-asset-backed commercial paper securities that are newly accepted as collateral under the MMLF, and securities held by affiliated MMFs. However, I do not find an additional yield-decreasing effect of the MMLF on lower rated securities or nonfinancial sector securities. After the implementation of the MMLF, domestic MMFs seem to increase the weight of nonfinancial sector securities, which helps them achieve a higher return.     

环境规制对碳效率的多重路径及门槛模型研究

从结构升级及效率提升两大维度刻画环境规制对碳排放效率的关系及作用机制，研究环境规制是如何提升城市碳排放效率的。基于2006—2019年中国279个城市层面数据，采用非参数百分位自抽法，逐步回归法、Sobel检验和交互调节模型验证影响路径，并利用门槛模型探讨不同路径下环境规制的调节作用。结果表明：(1)环境规制促进城市碳排放效率提升，但存在区域异质性；(2)环境规制通过促进产业结构高度化、绿色技术创新和能源效率升级提高碳排放效率，产业结构合理化及产业集聚“遮掩”了环境规制的激励作用；(3)环境规制对提升碳排放效率存在多种门槛效应和调节机制。发挥环境规制对碳排放效率结构和效率的双重激励时，需注意不同路径的维度问题，以提高准度，把握力度。     

Optimal reinsurance and portfolio selection: Comparison between partial and complete information models

We consider partial and complete information models to investigate how partial information has a unique quality over complete information for insurers. We find that optimal reinsurance and investment strategies for the partially informed insurer depend on prior beliefs, whereas those for the completely informed insurer do not. In addition, information quality can affect insurer behaviour, mainly through the relative difference between risk-adjusted market premium and risk-adjusted insurance premium projected on the financial markets. Numerical results indicate that partial information increases the conservativeness of insurer strategies.
