This paper compares the resilience of ethical (Islamic and socially responsible) indexes among five developed (US, UK, Japan, Canada, Australia) and three emerging markets (Brazil, India, South Africa) during the period following the 2008 subprime crisis. It relies on a multivariate CAPM-EGARCH model that accounts for sudden changes in volatility through the application of an iterated cumulative sums of squares (ICSS) algorithm on daily data over the sample period 2008–2014 to model time-varying volatility and ensure reliable estimates. The study confirms the lower systemic risk associated with Islamic indexes during the bearish period and reports that SRI, despite being more subject to systemic risk, offered higher alphas in highly integrated markets, while Islamic indexes performed better in less integrated ones. The evidence also reveals a very limited increase in the models’ predictability power from the integration of sudden changes in volatility into the EGARCH models during the full sample period. This limit is more marked during the bearish sub-period. Our findings have important implications for international investment and portfolio diversification perspectives in times of financial downturn.  相似文献

This paper examines the cumulative market reaction to the events related to deferral of internal control audit requirement under the Sarbanes-Oxley Act of 2002 and its elimination under the Dodd-Frank Act of 2010 for nonaccelerated filers (small firms). We document that small firms experienced negative cumulative abnormal returns around these events; and the differences between the cumulative abnormal returns for small firms and the two control groups (accelerated and large accelerated filers) were negative and significant at the 1% level. These results support the notion that market participants value the reliability of financial information irrespective of the firm size. Within the small firms, we find no firm characteristic significantly explains the market reaction to the events considered. That is, all small firms lost market value in reaction to the events that delayed and eliminated their internal control audit requirement.  相似文献

This paper provides a bibliometric and Scientometric analysis of the corporate social responsibility (CSR) in banking sector. Our study analyzes 551 articles from the Scopus database to find out the relationship between CSR and banking. A bibliometric method was used to visualize the results using R-studio and VOS viewer software. The Scientometric analysis was conducted to determine the findings and mappings of the research themes, directions of current and future research, impact, co-occurrence, co-citations and impact and collaboration trends. We explore how CSR literature has evolved over the years in the banking sector between 1993 and 2021. We find that publication in the CSR and banking domain has increased significantly during 2017 and 2021. Social aspects, board of directors, CSR, environment, competitions, Islamic banking, sustainability, disclosure, ethics, legitimacy theory, sustainable banking, loyalty, and brand equity are the popular research trends and collaboration trends identified. We also provide further scope of the study based on the extensive review of the past literature. Our findings may provide help to future researchers, bankers, and regulators in understanding the current trends and future research progression in the CSR and banking sector.  相似文献

Building on social exchange theory and attribution theory, this study unpacks the relationship between employees' perceptions of organizational politics and job performance, considering the mediating effect of career plateau beliefs and the moderating effect of leader interpersonal unfairness. The findings provide empirical support for the theoretical predictions. An important reason for which perceptions of dysfunctional organizational politics reduce job performance is that employees develop beliefs that opportunities for their career development are limited. This mediating role of career plateau beliefs is particularly salient to the extent that employees are exposed to organizational leaders who treat them with disrespect. Organizations can mitigate the risk that highly politicized decision-making processes lead to negative performance outcomes by stimulating fair interpersonal relationships.  相似文献

This study extends prior research on the relationships between personality constructs and types of psychological contracts by exploring how the Big Five traits predict balanced psychological contracts. Further, we determine whether epistemic curiosity and rule‐following behavior are key mediators of the proposed relationships. We tested our proposed hypotheses using three‐wave time‐lagged data from 469 respondents. The results indicated that openness to experience was positively associated and both conscientiousness and neuroticism were negatively associated with balanced contracts. Extraversion and agreeableness were not associated with balanced contracts. We also established the mediating role of epistemic curiosity in the relationships between personality traits and balanced contracts, but there was no support for the mediating role of rule‐following behavior in the present study. These findings have important implications for managers and organizations in terms of selecting the right person for a job (person‐job fit) and ensuring employee retention (person‐organization fit), hence having a bottom‐line effect on firm performance. Future research directions are also discussed.  相似文献

  • This paper explores the effectiveness of cigarette warning labels across two countries, one (the UK) with new and stricter legislation where text based labels have been made more prominent and one (the USA) with less stringent regulation, where labels are less visible. Using longitudinal data from the two countries, the research seeks to investigate the impact of the different types of warning labels on the information processing by consumers. This paper assesses the effectiveness of warning labels in terms of: consumer attention, elaboration, contemplation on quitting and behavioural compliance. This study provides a comprehensive examination of these key factors in a fixed causal sequence. Structural equation modelling was used to test this model based on longitudinal panel survey data from the International Tobacco Control (ITC) Four Country Survey. Analysis of a sample of 901 US smokers and 1459 UK smokers yielded results in full support of all hypothesised relationships in the model proposed for both countries. Findings suggest that the new European Union policy of more prominent warning labels has a direct effect on influencing behavioural compliance by smokers.

Introducing large woody debris into streams is a common practice in restoration projects. Beyond the complexity of flow patterns and sediment movements in streams where woody debris are found or placed, it seems that our understanding of the basic hydraulics of large roughness elements in small channels remains limited. Underestimating the drag force affecting large roughness elements can compromise the success of stream restoration projects. Results from a simple experimental setting confirm that drag force estimates based on approaches developed for small cylinders are not valid when applied to large cylinders. Indeed, the classic drag force equation that uses an empirical drag coefficient is found to significantly underestimate measured drag forces, even when corrected for the ‘blockage ratio’. In contrast, application of specific momentum can yield good estimates of the drag force. A dimensionless depth is defined in a 1D context as a function of the flow depth, critical flow depth and cylinder diameter. A cylinder is considered to be ‘large’ when this dimensionless depth is smaller than 2. In this instance, a relationship is established to estimate the upstream flow depth and the drag force acting on the cylinder. This research bridges the small roughness element theory widely recognized in hydraulic engineering with the theory applicable to large, flow controlling structures such as weirs. From a practical perspective, this research can be used to assist in the design of engineered large woody debris structures. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

One of the key elements in improved management and better planning for aquifer maintenance is the ability to predict changes in aquifer depth. In order to forecast changes in aquifer depth in Qazvin plain, four methods, including Classification and Regression Tree (CART), Reduced Error Pruning Trees (RepTree), M5-Pruned (M5P), and M5Rule, were used in this work. The absolute mean error (MAE) and coefficient of determination (R2) data show that the CART algorithm performs better than other algorithms at forecasting changes in aquifer depth. The CART algorithm's prediction findings showed that the aquifer's behavior in the two seasons was entirely different. In the first stage, which began in November and continued through April, there was an annual average depth of 0.045 m. The aquifer depth has been greatly influenced by rising precipitation and falling air temperature. The aquifer experiences an average decline of 0.15 m in the second portion, which runs from May to October. Aquifer depth has significantly decreased as a result of declining natural water supplies and rising agricultural water use. It is advised to utilize a crop scheme with reduced water need when rainfall reduces due to the strong effect of changes in aquifer depth from rainfall with a delay of one to three months ago.

In this article, we avail of International Accounting Standards IFRS 7 to investigate the usage and motivation of hedging by firms in the Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates). The results of our panel and cross-sectional data logistic regressions indicate a focus on foreign exchange exposure, interest rates risk, and commodity risk in this region. We find that the use of hedging instruments in this region is also influenced positively by the firm’s size and, to a lesser degree, positively by the firm’s gearing ratio and negatively by its propensity to growth. The level of activity, nevertheless, remains lower than is the case for firms globally.  相似文献

This study reviews literature on the Islamic banking sustainability and presents directions for future research. The article discourses scholars’ and practitioners’ views on the two perspectives of sustainability in relation to the objectives of Islamic banking and finance. That there are limited studies on Islamic banking sustainability is one of the major issues presented in the article. The study highlights essential issues on the sustainability without in-depth empirical analysis. The needs for long-term economic, social, and environmental sustainability are not a compromising issue. Therefore, Islamic banks must strike a balance between the institutional, societal, and environmental sustainability in order to achieve the objective of Sharia.  相似文献
