The purpose of this study is to assess the impact of nonfinancial sustainability reporting (NFSR) on enterprise value moderated by the management legitimate authority (MLA) for companies listed on the Tehran Stock Exchange.

To this aim, 190 firms were assessed during 2014–2019. This study used Arianpoor and Salehi’s indicators. The scoring method for NFSR, environmental sustainability reporting (ESR), social sustainability reporting (SSR) and governance sustainability reporting (GSR) was based on Zimon et al. Also, the CEO pay slice index was used to calculate the management’s legitimate authority. Tobin’s Q was used as a standard measure for the firm value, providing a suitable means of comparison.

The results revealed that NFSR affects enterprise value positively. In addition, ESR and SSR positively affect the enterprise value. However, GSR did not affect the enterprise value. MLA affects the relationship between NFSR/ESR/SSR/GSR and enterprise value, resulting from the effect of MLA on firm-related information quality and transparency.

Linking NFSR and management’s legitimate authority to firm value will enable managers to lead in helping firms enhance transparency and disclosure, improving their reporting standards and increasing the enterprise value. This, in turn, will ultimately result in better sustainability and governance practices.

The results can help understand that analysts and investors somehow consider discussions related to the NFSR in decisions related to the company’s value, and positive market reactions to these practices’ disclosures can motivate firms to improve value and performance.

The majority of prior research in this field has focused on developing countries. An international perspective is critical, and this study helps draw a more contextualized picture of sustainability than before. In addition, the present research explored the management’s legitimate authority role, which is considered an innovative aspect.

This study aims to provide a qualitative framework for satisfactory sustainable education for international accounting students using a meta-synthetic approach.

To determine the components and indicators of satisfactory sustainable education for international accounting students, a meta-synthesis allows for the attainment of the objectives of study. In the first phase of study, international related literature was reviewed (n = 2,176). After several screenings for measuring the quality of the related literature including Critical Appraisals Skills Program (CASP), the total number of selected papers was 48, and 2,128 were excluded.

The present research proposed a comprehensive conceptual model for sustainable education and international accounting students’ satisfaction, with seven components and 63 indicators. To assess the credibility of phases, the indicators were presented to five experts independently. The reliability of the proposed conceptual model was tested using Cohen’s Kappa coefficient and analyzed in SPSS. Kappa’s coefficient showed that the agreement level was high and the reliability was high too.

Sustainable education and student satisfaction are crucial for maintaining a competitive international education market. There are ongoing debates about accounting education, particularly accreditation challenges and the need for clear regulations on academic interaction with practice. Accounting education has also been criticized for being outdated, promoting surface-level learning and neglecting the development of broader skills in university graduates. Therefore, it is important to understand sustainable education for international accounting students. The present study aims to identify the aspects of accounting educational services that international accounting students perceive important for increasing satisfaction. This research provides empirical evidence and suggests potential avenues for future research in other countries.

This study aims to explore the relationship between firm risk, capital structure, cost of equity capital and social and environmental sustainability during the COVID-19 pandemic for companies listed on Tehran Stock Exchange.

To this aim, the information about 190 companies in 2014–2020 was retrieved to be analyzed. The total risk and systematic risk were used as the indicators of company risk; the industry-adjusted earnings price ratio (IndEP) and GORDON were used for the cost of equity capital. To measure social sustainability and environmental sustainability, the procedure suggested by Arianpoor and Salehi (2020) was used.

Underleveraged firms have had a lower total risk during the COVID-19 pandemic, while overleveraged firms have not had a higher risk during this time. In overleveraged firms, using systematic risk has a negative impact on social sustainability during the COVID-19 pandemic. In overleveraged firms, using total risk and systematic risk has a significant negative impact on environmental sustainability in the pandemic. Besides, overleveraged firms have a lower cost of equity capital (IndEP) during COVID-19.

To the best of the authors’ knowledge, no similar study has so far examined the joint impact of COVID-19 and corporate risk on social and environmental sustainability and also the joint impact of COVID-19 and capital structure on the cost of equity. This study contributes to the related literature by providing corporations with insightful post-pandemic directions on capital structure decisions and social and environmental activities. Furthermore, this research and the relevant findings can help understand and develop social responsibility in Iran as a developing country.

The study's main objective is to identify business sustainability performance indicators and analyze the mutual relationship between different business sustainability components in Iran.

To achieve research objectives, the 125 indicators of Business Sustainability Performance in Arianpoor and Salehi (2020) were used. For data collection, a questionnaire is designed and developed. Moreover, the Delphi method is used to determine the indicators related to business sustainability performance. Accordingly, we attempted to send the questionnaire to 346 experts and qualified opinion-leaders in the study area to utilize their opinions in our project. Finally, 108 questionnaires were analyzed statistically.

In this study, the confirmatory factor analysis (CFA), binomial test, one sample t-test, one sample Kolmogorov–Smirnov test and Kruskal–Wallis test are used. The results of statistical tests show that among 125 proposed indicators, 11 indicators were eliminated. Hence, to assess business sustainability performance in the listed firm on the Tehran Stock Exchange, 114 indicators were analyzed. To achieve the study's objective, the relationship between financial and non-financial sustainability performance and their effect is analyzed using the Smart PLS Software. Findings indicate that there is a mutual relationship between financial and non-financial sustainability performance in Iran. There is also a relationship between the operational component and research component and non-financial sustainability performance. In contrast, as for the growth component and non-financial sustainability performance, there is no significant relationship. Also, root means squared error (RMSE) values suggest a reasonable model-data fit.

The type and characteristics of different regions have a significant role in the reporting and differ according to different economic conditions. The discussion of business sustainability and its reporting is important; therefore, essential indicators were identified in this study. In addition, all aspects of sustainability performance are considered cohesively to analyze the mutual relationship between different components of sustainability performance and to be able to make more appropriate decisions in future studies about performance evaluation and reporting using the results of this paper.

This study aims to investigate the impact of risk-taking and auditor characteristics on value creation in companies listed on the Tehran Stock Exchange. In addition, it investigates the moderator role of auditor characteristics in the impact of risk-taking on value creation, especially in pre-Covid 19 and post-Covid 19 pandemic.

The information about 199 company in 2014–2021 was examined. In the present study, in accordance with the related theoretical literature and the importance of auditor specialization, auditor tenure and auditor reputation, these factors were considered as the auditor characteristics.

The present findings based on the generalized least squares (GLS) method showed that risk-taking positively affects the value creation. The auditor characteristics (auditor specialization, auditor tenure and auditor reputation) have a significant positive effect on the value creation. Furthermore, the auditor characteristics enhance the impact of risk-taking on value creation. The results of generalized method of moments method and robust regression analysis are consistent with the GLS results. To take into account the Covid-19 conditions, the data were divided into pre-Covid-19 and post-Covid-19 years. The results showed that auditor characteristics moderate the impact of risk-taking on value creation in pre-Covid 19 and post-Covid 19.

The study highlights the role of auditor characteristics in the value creation, especially in the emerging market. Given that Covid-19 has seriously damaged global economic well-being and has put companies at a double risk, the present findings can be useful for managers, investors and the international community, and help company managers make risk-taking policies and select auditors with appropriate characteristics.

The present study aims to investigate the impact of internal control effectiveness on supply chain management efficiency (SCME) and capital allocation efficiency for companies listed in the Tehran Stock Exchange (TSE). In addition, it investigates the mediating role of supply chain management efficiency in the relationship between internal controls and capital allocation efficiency.

The data about 191 companies in 2014–2022 were examined. The sales per inventory ratio was used to calculate SCME. The present study also applied the Generalized Method of Moments (GMM) for endogeneity concerns.

The results showed that internal control effectiveness has a significant positive effect on SCME. Moreover, internal control effectiveness and SCME significantly positively affect capital allocation efficiency. SCME has a mediating role in the relationship between internal control effectiveness and capital allocation efficiency. These findings remained robust even after several robustness tests. In addition, this study tested the results' robustness by dividing data into the pre-COVID-19 and post-COVID-19 years. The previous results were also confirmed according to the robustness test of COVID-19.

Challenges in the supply chain often hinder capital allocation efficiency. In addition, enterprises should try to establish strong internal controls to ensure SCME. Therefore, the relationship between internal control effectiveness, SCME and capital allocation efficiency is complex and underscores the importance of robust internal controls in optimizing resource allocation within organizations. Interestingly, this topic has not been extensively researched in accounting and business research, and there is a lack of empirical evidence on these effects. Consequently, this study aims to fill the gap and identify potential opportunities for new research directions.

This study aims to assess the effect of material internal control weaknesses (MICW) on the relationship between ownership structures and future-oriented disclosure.

A total number of 197 firms were assessed in this study during 2014–2021. Two measures were used for MICW. First, the number of existing MICW was assessed in independent auditors’ reports. In Iran, the maximum number of weaknesses is 13. Second, the scoring (0 or 1) method was used as a dummy variable, 1 for a firm with MICW and otherwise 0. Moreover, the scoring (0 or 1) method was used to measure the level of future-oriented disclosure of 13 indicators.

The findings showed that institutional ownership and managerial ownership have a significant positive effect on future-oriented disclosure, whereas the MICW have a significant negative effect on future-oriented disclosure. In addition, MICW played a moderator role in the relationship between ownership structures and future-oriented disclosure. The robustness checks confirmed the results.

As the studies conducted on future-oriented disclosure and the contributing factors are limited, and also the effect of MICW on future-oriented disclosure is not explored, the present findings can show the importance of the study, and fill the gap in this field. This study offers theoretical and practical implications to drive policymakers and managers to the effectiveness of internal control and future-oriented transparency.

The present study investigates the impact of managerial psychological characteristics on the supply chain management efficiency (SCME) of companies listed in Tehran Stock Exchange.

To this aim, information about 215 companies was analyzed during 2014–2021. The sales per inventory ratio was used to calculate SCME. In the present study, the focus is on characteristics such as managerial entrenchment, managerial myopia, managerial overconfidence (MOC) and managerial narcissism, all considered as managerial attributes.

The present findings showed that managerial myopia/managerial entrenchment (MOC/managerial narcissism) have a negative (positive) effect on SCME. Hypothesis testing based on robustness checks confirmed these results. Moreover, the findings are presented separately for companies with high business strategy (first quarter) and low business strategy (third quarter). The results show that at low levels of differentiation strategy, managerial entrenchment does not have a significant effect on SCME while other managerial attributes have a significant effect on both high and low business strategy.

The present study contributes to the identification of managerial psychological characteristics influencing SCME to advance future studies and support practical efforts. The present findings can prove the significance of this research and fill the existing gap in research.

The present study investigated the impact of earnings volatility and environmental uncertainty on accounting comparability in an emerging economy and the moderating role of COVID-19 pandemic for the companies listed on Tehran Stock Exchange (TSE).

The data about 181 companies during 2014–2021 were examined. In this study, accounting comparability was predicted for the firms' accounting systems and the coefficient estimates were calculated. The present study used the coefficient of variation of sales to capture sales volatility as the primary environmental uncertainty measure.

The results showed that both the earnings volatility and environmental uncertainty have a significant negative effect on accounting comparability, and that COVID-19 significantly increases the negative impact of earnings volatility and environmental uncertainty on accounting comparability. The hypothesis testing based on robust, GLS, GMM, GLM, OLS regressions and t+1 test confirmed these results.

The present study aimed to develop knowledge-providing benefits for companies about the accounting comparability and managing more efficient decisions. The present findings help investors to understand and evaluate the performance of firms more accurately especially in earnings volatility and environmental uncertainty conditions and in the wake of a pandemic crisis such as COVID-19.

This study aims to explore the moderating role of institutional ownership in the impact of auditor industry specialization and the cost of equity on earnings management in Tehran Stock Exchange.

A total number of 198 firms were assessed in this study from 2014 to 2021. In this study, both accrual earning management (AEM) and real earnings management (REM) have been included. The industry-adjusted earnings price ratio and Gordon Growth Model were used for the cost of equity capital. In addition, auditor’s within-industry market share was used as a proxy for auditor industry specialization.

The results showed that institutional ownership positively moderates the impact of auditor industry specialization on AEM/REM. Furthermore, institutional ownership positively moderates the impact of cost of equity on AEM/REM. Hypothesis testing based on a robust regression and t + 1 test were also used for the results.

Previous studies have reported mixed results of this empirical question whether institutional ownership actually monitors managers and control earning management, considering the auditor industry specialization and the cost of equity. To the best of authors’ knowledge, this is a pioneering study to fill the existing gap. This study would not only benefit companies to manage financial and strategic decisions more efficiently but also help national and international society apply effective mechanisms to assist companies in decreasing earning management and increasing the firm performance, and try to push the market into a favorable direction.
