ABSTRACT
Purpose: 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). Design/methodology/approach: 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. Findings: 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. Originality/value: 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. © 2023, Emerald Publishing Limited.
ABSTRACT
Purpose: 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. Design/methodology/approach: 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. Findings: 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. Originality/value: 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. © 2022, © Emerald Publishing Limited.
