This study aims to investigate the impact of coronavirus disease 2019 (COVID-19) on the relationship between buyer firms' corporate social responsibility (CSR) activities toward business partners, such as suppliers, and firm value. The study further explores the role of ownership structure in shaping this relationship.

The authors employ a difference-in-differences (DID) regression method to distinguish between the periods before and during the COVID-19 crisis. The authors utilize data from firms listed on the Korean stock market between 2013 and 2020.

The results show that CSR activities for suppliers have a positive impact on the value of buyer firms. Furthermore, this positive relationship is amplified during the COVID-19 period. In addition, the study finds that the positive relationship is more prominent in samples with higher ownership by controlling shareholders or foreign investors.

Overall, this study makes a valuable contribution to the existing literature by examining the positive effects of CSR activities on firm value and by shedding light on the role of ownership structure in influencing these effects. Additionally, the study emphasizes the significance of CSR activities for business partners in mitigating supply chain disruptions during the COVID-19 pandemic.

The paper aims to estimate abnormal audit fees more precisely than the traditional audit fee model by applying an artificial intelligence (AI) method.

The AI technique employed in this paper is the deep neural network (DNN) model, which has been successfully applied to a wide variety of decision-making tasks. The authors examine the ability of the classic ordinary least squares (OLS) and the DNN models to describe the effects of abnormal audit fees on accounting quality based on recent research that demonstrates a systematic link between accruals-based earnings management and abnormal audit fees. Thus, the authors seek to imply that their new method provides a more precise estimate of abnormal audit fees.

The findings indicate that abnormal audit fees projected using the DNN model are substantially more accurate than those estimated using the classic OLS model in terms of their association with earnings management. Specifically, when abnormal audit fees predicted using the DNN rather than the OLS are incorporated in the accruals-based earnings management model, the adjusted R²s are larger. Additionally, the DNN-estimated coefficient of abnormal audit fees is more favorably associated to earnings management than the classic OLS-estimated coefficient. Additionally, the authors demonstrate that the DNN outperforms OLS in terms of explanatory power in a negative discretionary accruals subsample and a Big 4 auditor subsample. Finally, abnormal audit fees projected using the DNN method provide a better explanation for audit hours than those estimated using the OLS model.

This is the first approach that utilized a machine learning technology to estimate abnormal audit fees. Because more precise measurement yields more credible research results, the findings of this study imply a significant advancement in calculating unusually higher audit fees.

The purpose of this study is to examine the association between additional audit efforts and clients’ future equity value. The study hypothesizes that auditors’ additional audit efforts directly increase clients’ stock return performance. Additionally, this study expects that the additional audit effort lowers the likelihood of audit failure and improves accounting information quality, thereby indirectly increasing clients’ future equity return performance.

The regression and portfolio return tests are conducted using observations from 2003 to 2016. This study uses the abnormal audit hours as a proxy for additional audit effort using mandatorily disclosed audit hour data from Korean listed firms. The study also conducts mediation analyses to examine the causal intermediate steps that link audit effort to client equity return performance.

The paper documents a significant and positive association between abnormal audit hours and clients’ subsequent years’ stock return performance and Tobin’s Q. This finding is accentuated for clients audited by Big N auditors or with greater demand for superior audit service. This finding is robust after controlling for various proxies of accounting quality. The portfolio return tests also find evidence that investors cannot fully perceive the value of audit efforts. A battery of additional tests does not alter the main findings.

The results provide implications for investors and policymakers by emphasizing the importance of audit efforts in value-creation. Moreover, this study’s findings suggest that auditors’ assurance, insurance and information roles are all the important drivers of this value-creation.

This study highlights a prominent feature of audit effort that enhances the value of auditees.

The purpose of this study is to examine the relationship between explanatory language, audit fees and audit hours to demonstrate that auditors use explanatory language in audit reports to explain perceived audit risk.

The authors construct the sentiment value, a novel audit risk proxy derived from audit reports, using big data analysis. The relationship between sentiment value and explanatory language is then investigated. The authors present the validity of their new metric by examining the relationship between sentiment value and accounting quality, taking audit fees and hours into account.

The authors first find that reporting explanatory language is positively related to audit fees. More importantly, the authors provide an evidence that explanatory language in audit reports is indicative of increased audit risk as it is negatively correlated with sentiment value. As a positive (negative) sentimental value means that the audit risk is low (high), the results indicate that auditors describe explanatory language in a negative manner to convey the inherent audit risk and receive higher audit fees from the risky clients. Furthermore, the relationship is strengthened when the explanatory language is more severe, such as reporting the multiple numbers of explanatory language or going-concern opinion. Finally, the sentiment value is correlated with accounting quality, as measured by the absolute value of discretionary accruals.

Contrary to previous research, the authors’ findings suggest that auditors disclose audit risks of client firms by including explanatory language in audit reports. In addition, the authors demonstrate that their new metric effectively identifies the audit risk outlined qualitatively in audit report. To the best of the authors’ knowledge, this is the first study that establishes a connection between sentiment analysis and audit-related textual data.

Discusses the 6th ITCRR, its breadth of textile and clothing research activity, plus the encouragement given to workers in this field and its related areas. States that, within the newer research areas under the microscope of the community involved, technical textiles focuses on new, ‘smart’ garments and the initiatives in this field in both the UK and the international community at large. Covers this subject at length.

Looks at the eighth published year of the ITCRR and the research, from far and near, involved in this. Muses on the fact that, though all the usual processes are to the fore, the downside part of the industry is garment making which is the least developed side. Posits that the manufacture of clothing needs to become more technologically advanced as does retailing. Closes by emphasising support for the community in all its efforts.

The purpose of this paper is to examine a curvilinear effect of legislative constraints on foreign debt.

A cross-sectional, time-series data analysis of 68 developing countries during the period from 1981 to 1999 was performed.

Foreign borrowing is most likely to increase at both low and high levels of legislative constraints, while it is most likely to decrease at moderate levels.

The paper is a first-cut empirical analysis of a curvilinear relationship between legislative constraints and foreign debt.

Drawing on the theories of social capital and leader–member exchange (LMX), the authors examined the moderated mediation relationships of psychological ownership and perceived supervisory support on social capital and organizational knowledge.

To test the proposed model, the authors collected data from 522 employees working in large corporations in South Korea.

The authors found that (a) social capital was positively related to organizational knowledge sharing, (b) perceived supervisor support mediated the linkage between social capital and knowledge sharing and (c) psychological ownership moderated the indirect effect of social capital on knowledge sharing through perceived supervisor support, such that the indirect effect was stronger for employees with low rather than high psychological ownership.

This study sheds new light on how the nature of relationship between the leader and followers as well as individual's psychological ownership play a crucial role in knowledge sharing.

Today, psychological well-being is increasingly valued by organizations because it is integral to employee performance. The style of leaders supervising their subordinates is an important influence on their psychological well-being. Abusive supervision can lead to a depletion of resources among their subordinates by inducing psychological stress, leading to a decline in psychological well-being. In this research, the authors use the conservation of resources (COR) theory and self-determination theory to examine the mechanism between abusive supervision and psychological well-being. This study can contribute to previous research by applying the COR theory and self-determination theory, which were not discussed, to explain the relationship between leader's leadership behavior and psychological well-being of organizational members.

The authors conduct a multi-time data collection method of two waves with six-week intervals. The authors received 322 samples and conducted a confirmatory factor analysis to test result validity and used multiple regression to examine the direct and moderating effects. Additionally, the authors used the bootstrapping method to test mediating effects.

The results show that abusive supervision is negatively related to psychological well-being and self-determination plays the mediating role between them, while perceived person-organization fit is the moderator between self-determination and psychological well-being.

The authors identified self-determination as the mediator between abusive supervision and psychological well-being and perceived person-organization fit plays the moderating role between self-determination and psychological well-being.

This study aims to identify people’s perceptions of what behaviourally differentiates effective managers from ineffective managers within a South Korean (SK) public sector organization, and the extent to which the findings are similar or different to those of an equivalent previous study in the SK private sector.

Adopting the “pragmatic approach” and assuming a post-positivist ontology and constructivist–interpretivist epistemology, examples of “effective” and “ineffective” managerial behaviour were collected from managers and non-managerial employees in an SK central government Ministry using the critical incident technique. The collected critical incidents were coded, classified and reduced to a smaller number of behavioural categories. These were then compared against equivalent findings from a previous SK private sector replication study using open, axial and selective coding to identify generic behavioural criteria (GBCs)

High degrees of convergence point towards the emergence of a “two-factor” SK behavioural taxonomy of perceived managerial and leadership effectiveness comprised of positive (n = 11) and negative (n = 4) GBCs of effective and ineffective managerial behaviour.

The GBCs constituting the deduced SK behavioural taxonomy could be used by HRD practitioners to critically evaluate the efficacy of extant management and leadership development (MLD) programmes, or to inform/shape the creation of new MLD programmes. Additionally, they could be used by other HR professionals to critically evaluate the relevance and efficacy of the assessment criteria used for existing management selection, 360-degree feedback and formal performance appraisal systems.

The emergence of an SK behavioural taxonomy through Type 3 (emic-as-emic) and Type 4 (emic-and-etic) indigenous research is a rare example of Eastern mid-range theory development.
