Purpose With theoretical underpinnings in the conservation of resources theory, this research aims at understanding the link between workplace ostracism (WPO) and its effects on customers' interests in the context of COVID-19, with the mediation of stress and moderation of self-efficacy (SE). Design/methodology/approach The study followed a time-lagged design. A sample of 217 frontline employees working in the food sector of southern Punjab, Pakistan, responded to the study questions using the survey method with structured questionnaires. A Statistical Package for the Social Sciences (SPSS) tool was utilized for data analysis with bootstrapping and PROCESS macro. Findings The findings show that an important mechanism by which ostracism translates into customer service sabotage (CSS) is the increase in perceived stress levels of the employees. Additionally, SE was found to be an important personal resource that acts as a moderator in the said relationship. Practical implications Employees with high SE sense less workplace stress even during a pandemic. Leadership should consider the stress-alleviating effect of SE for lessening the damaging influence of WPO on customers. Originality/value The study fills an important empirical gap in the context of the COVID-19 pandemic, by showing that due to resource loss perceived by employees while being targeted by ostracism, they may decide to transfer their frustration towards organizational customers by sabotaging their service experience.

Purpose This study attempts to examine the effect of greenhouse gas (GHG) emissions disclosure and its compounding effect with environmental, social, and governance (ESG) disclosure on firm value in Korea. This study focuses on the unique institutional setting in Korea that implements mandatory GHG emissions disclosure and voluntary ESG disclosure. Design/methodology/approach Using a dataset comprising 25,968 firm-year observations from publicly listed Korean firms from 2000 to 2021, we applied an ordinary least squares (OLS) regression model to test hypotheses. Findings The results show that, in a voluntary disclosure regime, ESG disclosure has a positive impact, whereas in a mandatory disclosure regime, GHG emissions disclosure has a negative impact on firm value. The results also indicate that when a firm discloses both its GHG emissions and ESG performance information, the voluntary disclosure of ESG information synergistically mitigates the adverse effects of mandatory disclosure of GHG emissions information. This synergy contributes significantly to enhancing the firm’s overall value. The findings indicate that a firm can enhance its value by proactively disclosing ESG information, especially when it is compulsorily required to report GHG emissions data. Originality/value This study investigated the effect of corporate non-financial disclosure on firm value by shedding light on the differential attributes between voluntary and mandatory disclosures and between quantitative and qualitative information.

Purpose Although publicly listed firms in Sri Lanka have been increasingly adapting sustainability reporting into their annual reporting practices, a limited number of firms prepare sustainability reports by integrating sustainable development goals (SDGs) into reporting mechanisms. This study attempts to develop an index to monitor firms' sustainability reporting practices based on Global Reporting Institute (GRI) guidelines integrating SDGs. Design/methodology/approach This paper develops a sustainability score index using the 17 SDGs utilising the results of content analysis of corporate annual reports of a selected sample of 100 firms listed on the Colombo Stock Exchange (CSE). Principal component analysis was employed to examine the reliability of data in the developed index. Findings Findings show that the developed scoring index is efficient for evaluating the contents of the sustainability reports of Sri Lankan firms. Sustainability reporting practises with regard to the SDGs were observed to have a turbulent period from 2015 to 2019 and the SDGs 12 and 15 were identified to be mostly reported in Sri Lankan corporate sustainability reports. Research limitations/implications The results of the study add to knowledge on the monitoring of sustainability reporting practises with reference to SDGs. The study outcomes are useful for the investors, stakeholders, and statutory bodies to measure the sustainable performance of business firms and assess the firm’s commitment towards the global sustainability agenda. Originality/value To the best of our knowledge, this is the first study that constructs a sustainability reporting score index integrating SDGs.

Purpose This study explores the variance in investor responses to the corporate social responsibility (CSR) performance of firms, as influenced by information sources and investor types. Design/methodology/approach This study applies a short-term event study and cross-sectional analysis with unique CSR datasets obtained from newspaper articles and the Dow Jones Sustainability Index. Findings Investor reactions are significantly shaped by their sources of information. Individual investors are found to predominantly respond to accessible news announcements, whereas institutional investors show heightened sensitivity to adverse news from both scrutinized sources. Foreign investors, mirroring institutional investors' patterns, uniquely react positively to index additions. Research limitations/implications Investors’ assessment of CSR activities varies due to the differing sources of information obtained; further, it is affected by the type of investor. Practical implications The findings guide public relation managers in strategizing CSR communication toward diverse investor types. This includes recommending targeted approaches for Japanese individual investors through newspapers and TV, exercising caution in disseminating adverse news to Japanese institutions, and promoting and justifying CSR actions to foreign investors. It underscores the need for a strategic investor relations frameworks that considers accessibility, literacy, and investors' interests. Originality/value This study examines the relationship between sources of information for CSR activities and investors’ responses, an area under-represented in the literature. The author uses CSR announcement data, collected from newspapers to make the results more accurate and relevant.

Purpose Green innovation by organisations has the potential to create social impact across five dimensions: social capital, collective identities, environmental literacy, community well-being and human capital. However, the link between green innovation and these dimensions of social impact is underexplored, particularly in developing countries such as Vietnam, where environmental policies are still being framed. Thus, this study provides an exploratory analysis of the social impact of green innovation undertaken by organisations in Vietnam. Design/methodology/approach The perspectives of a focal organisation in Vietnam and three related stakeholders are examined. Data were obtained from the research participants using a photo-elicitation interviewing strategy with concept cards. A hybrid deductive–inductive approach to thematic analysis identified five themes. Findings There is evidence that green innovation positively influences social impact across the five identified dimensions. Additionally, the analysis suggests that green innovation can generate spillover effects amongst stakeholder organisations. Research limitations/implications An obvious limitation of this study is that it is based solely on interviews of executives and managers linked to a focal organisation that is already undertaking green innovation. Due to time and resource limitations, it was not possible to examine other sources of information, such as documentary evidence, which would have increased the reliability of the data. Practical implications This paper makes two contributions. First, it presents stakeholders’perceptions of the social impact of an organisation’s implementation of a green innovation strategy. Second, the study demonstrates the use of a novel photo-elicitation technique – concept cards – in undertaking interviews with busy business executives. Such an approach has rarely been used in business settings. Social implications This study provides managers with a framework for measuring the social impact of their green initiatives. It is no longer sufficient to evaluate a firm’s financial performance alone. With a growing emphasis on the United Nations Sustainable Development Goals, managers must be able to report the impact of their work beyond business boundaries. Our research findings are also insightful for policymakers working in innovation-related government, providing a comprehensive framework for evaluating the social impact of innovation. Originality/value This study investigates the emerging concept of green innovation using a novel “concept cards” interviewing technique. The perceptions of individuals from a sample of organisations in Vietnam provide a practical foundation for organisations’ future development of effective green innovation strategies.
