This study aims to examine the moderating role of sustainability assurance in the nexus between corporate governance and firm performance in India. The data relating to 35 environmentally sensitive companies among the top 100 National Stock Exchange (NSE) listed entities were gathered from the ProwessIQ Database and annual reports of companies during 2016–2022. The fixed effect regression model was employed. The results show an insignificant effect of board effectiveness on firm performance as measured by return on assets (ROA), return on equity (ROE), and Tobin’s Q. Similar findings were documented on the audit committee effectiveness and firm performance nexus, except for Tobin’s Q (β = 0.316). In addition, the study did not support the moderating role of sustainability assurance on the board effectiveness and firm performance nexus, indicating the presence of ineffective corporate governance mechanisms. However, the results show that sustainability assurance significantly and negatively moderates the relationship between audit committee effectiveness and ROA (β = –0.021), ROE (β = –0.074), and Tobin’s Q (β = –0.996). This implies that the practice of external assurance of sustainability reports by firms with audit committee effectiveness is an additional burden due to the extra cost involved. Further, the result indicates the learning curve effect among Indian companies. Thus, the findings suggest the need for regulatory focus on encouraging sustainable business practices in terms of effective corporate governance and sustainability assurance.\u0000AcknowledgmentThe authors are grateful to Manipal Academy of Higher Education (MAHE), Manipal, for providing financial assistance in the form of a “JRF Contingency Grant” for this research article.","PeriodicalId":507796,"journal":{"name":"Investment Management and Financial Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141924140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Food supermarkets play an integral role in socio-economic development of the country. The study employed an econometric approach utilizing fixed effect panel data. Drawing information from audited financial statements, data were gathered from four major listed food supermarkets in South Africa covering the period from 1994 to 2022, resulting in a total of 116 observations over 29 years. The robust longitudinal statistics obtained from balanced data revealed a significant positive correlation between equity financing, size of corporate governance, and current debt with financial performance, as measured by sales revenue at 0.0000, 0.054, and 0.000 significance levels, respectively. The findings indicate that as these variables increase, the financial performance of the studied food supermarkets (Shoprite, Woolworths, Spar, and Pick n Pay) also increases. Conversely, a negative and significant relationship is noted between company age, current assets, and financial performance at significance levels of 0.007 and 0.002, respectively. This suggests that as these variables increase, financial performance will decrease. As per the research findings, it is imperative for supermarkets to uphold a well-rounded blend of equity and debt and adopt inventive business approaches as they mature to improve financial outcomes. Therefore, the study proposes a framework focusing on internal factors that impact the financial performance of listed food supermarkets in South Africa.","PeriodicalId":507796,"journal":{"name":"Investment Management and Financial Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141799327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firms manage challenges through business strategies and financial constraints and deal with crash risk more proactively to overcome these impediments. This paper investigates the mediating role of financial constraints in the association between business strategy and crash risk, and the type of business strategy that influenced crash risk in Egyptian firms from 2014 to 2021. Data were obtained from financial statements and reports available in the Thomson Reuters database. A total of 792 observations were collected, representing 99 Egyptian firms. The statistical techniques employed in the analysis included ordinary least squares, modified least squares, and path analysis. The results indicate that a higher financial constraint ratio increases crash risk and has a mediating effect on business strategy and crash risk. Results show a positive impact of prospector strategy on crash risk using OLS and GLS, in line with the bad news hoarding hypothesis. Further research shows that prospector strategies have a positive effect on financial constraints. Egyptian firms have higher levels of information asymmetry, which leads to adopting a prospector business strategy and exerts a more pronounced positive influence on the likelihood of crash risk. A robustness check confirms the positive effect of financial constraints as a mediator variable on the relationship between prospector business strategy and crash risk.","PeriodicalId":507796,"journal":{"name":"Investment Management and Financial Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141803068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Addressing these challenges may necessitate increased investment. This study explores the relationship between intellectual capital efficiency and firms’ dividend policies and the potential impact of CEO characteristics on this relationship. An analysis was based on data from 90 Jordanian service and manufacturing companies from 2015 to 2019. The study employs the value-added intellectual capital coefficient (VAIC) to measure intellectual capital efficiency and uses the dividend payout ratio to represent dividend policy. The findings indicate a positive relationship between VAIC and dividend policy, suggesting that companies with higher intellectual capital efficiency tend to distribute higher dividends. However, CEO characteristics, such as age, tenure, and educational background, do not significantly affect this relationship. These results imply that strong corporate governance mechanisms are likely in place, ensuring effective decision-making processes and protecting stakeholders’ interests. By focusing on intellectual capital, firms can enhance their operational performance and attractiveness to investors, indirectly supporting economic stability.","PeriodicalId":507796,"journal":{"name":"Investment Management and Financial Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141815969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though past studies investigated COVID-19’s impact on firm performance, there is consensus on the role of firms’ Environmental, Social, and Governance disclosures between firm performance and the pandemic. With this view, the study aims to examine the impact of COVID-19 on firms’ financial performance with the moderating role of Environmental, Social, and Governance performance disclosure. To do so, the study retrieved data of Nifty 500 index companies from the Bloomberg database for a sample period ranging from 2016 to 2022. To this end, the study performed the fixed-effect regression and GMM model. The findings reveal a significant negative impact of the pandemic on Return on Assets (β =-4.812), Return on Equity (β =–.675), and Earnings Per Share (β = –2.875), highlighting the unfavorable effect of the pandemic on firm performance. Further results showed that firms’ Environmental, Social, and Governance performance disclosure positively moderates the connection between COVID-19 and Return on Assets (β = 3.231), Return on Equity (β = 0.032), and Earnings Per Share (β = 1.523), respectively. This indicates that companies actively involved in Environmental, Social, and Governance disclosure are less likely to suffer during the pandemic in terms of financial performance due to their ESG disclosures.","PeriodicalId":507796,"journal":{"name":"Investment Management and Financial Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141821687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of this study show that trained accounting personnel, attitudes about the importance of internal control implementation, and the existence of separation of duties in church organizations have a significant effect on the level of internal control of church finances. The results of the study strengthen support for the implementation of effective church financial internal control, which requires increasing the competency of accounting staff through accounting training, the attitude of organizational members to support the implementation of the church’s financial internal control system to make it more accountable, and the existence of a clear separation of duties within the organization to avoid fraud.","PeriodicalId":507796,"journal":{"name":"Investment Management and Financial Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141674936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome such a problem, there is a trend of using credit rating as the benchmark to appraise funding opportunities and applications in listed SMEs. As credit rating levels vary across time, subject to the performance of the listed SMEs, changes in the credit rating levels might trigger attention from listed SMEs, and actions might then be taken by the management to ensure that the credit rating is at the desired level. Since the literature in this strand of study is limited, this study aimed to examine the effect of credit rating downgrade and tightness of accounting standards on earnings management in listed SMEs. Employing a 2x3 between-subjects experiment manipulating credit rating downgrades (category or notch) and tightness of accounting standards (less tight, moderately tight, tight), it is evidenced that credit rating downgrades, especially notch downgrades, lead to more earnings management behaviors in the presence of a tight and less tight set of accounting standards. Different classifications of credit rating downgrades – notches and categories – will have different implications for earnings management based on the extent to which they are subject to external monitoring. As a practical matter, it is recommended that regulators exercise equal monitoring regardless of whether credit rating downgrades occur by category or notch.","PeriodicalId":507796,"journal":{"name":"Investment Management and Financial Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141674612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A firm with efficient cash management and optimum capital structure tends to have a better firm value. The current study examines the effect of capital structure and free cash flow on energy firms’ efficiency in Saudi Arabia. The data required for analysis were collected from a sample of seven energy companies from 2014 through 2022. The study used Data Envelopment Analysis to measure the efficiency of energy firms. Further, the simple regression and Generalized Linear Model were used to estimate the results. The study reports an average efficiency score of 1.13 for the energy companies, showing an efficiency increase. The results of simple regression are consistent with the results of the Generalized Linear Model. The study findings demonstrate that the association of firms’ capital structure is positive and significant (with a coefficient of 41.60, significant at a p-value of 0.01) to the efficiency of Saudi Arabian energy firms. Further, current research results indicate that firms’ free cash flows negatively affect the efficiency (with a coefficient of –0.79 and insignificant) of Saudi Arabian energy firms with no evidence. Therefore, the study accepts the association of free cash flow and firms’ efficiency as positive and rejects the alternative hypothesis that there is a negative association between free cash flow and efficiency in Saudi Arabian energy firms.\u0000AcknowledgmentThe researcher extends appreciation to Prince Sattam Bin Abdulaziz University for funding this research through the project number 2023/02/25856.","PeriodicalId":507796,"journal":{"name":"Investment Management and Financial Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141686124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
