This study aims to fill a gap in the literature by providing evidence for a “greenium” in the primary Sukuk market. The term “greenium” is defined in the study as the lower cost of capital or reduced yields that green Sukuk may offer compared to non-green Sukuk, reflecting investor willingness to accept lower returns for green investments. Therefore, the main aim of this study is to investigate the potential role of “greenium” as an incentive for issuers to fund eco-friendly projects, contributing to a sustainable environment.

This study uses propensity score matching techniques to provide an accurate comparison of pricing differences between green and non-green Sukuk issued in global primary markets during the period 2017–2022.

The results reveal that green Sukuk signify a “greenium” effect. This suggests that investors find green Sukuk attractive, willing to accept lower returns. Given the positive investor response to green initiatives in the market, issuers can capitalize on the growing demand for green Sukuk, leading to low-cost funding.

This study makes an important contribution to the literature at the interface of Islamic finance and environmental sustainability. In particular, it stands out by focusing on the pricing dynamics in the green Sukuk market and highlights the potential benefits of issuing green Sukuk to help achieve sustainability goals while providing access to lower cost of capital for the transition to a low-carbon economy.

The current study uses an advanced machine learning method and aims to investigate whether auditors perceive financial statements that are principles-based as less risky. More specifically, this study aims to explore the association between principles-based accounting standards and audit pricing and between principles-based accounting standards and the likelihood of receiving a going concern opinion.

The study uses an advanced machine-learning method to understand the role of principles-based accounting standards in predicting audit fees and going concern opinion. The study also uses multiple regression models defining audit fees and the probability of receiving going concern opinion. The analyses are complemented by additional tests such as economic significance, firm fixed effects, propensity score matching, entropy balancing, change analysis, yearly regression results and controlling for managerial risk-taking incentives and governance variables.

The paper provides empirical evidence that auditors charge less audit fees to clients whose financial statements are more principles-based. The finding suggests that auditors perceive financial statements that are principles-based less risky. The study also provides evidence that the probability of receiving a going-concern opinion reduces as firms rely more on principles-based standards. The finding further suggests that auditors discount the financial numbers supplied by the managers using rules-based standards. The study also reveals that the degree of reliance by a US firm on principles-based accounting standards has a negative impact on accounting conservatism, the risk of financial statement misstatement, accruals and the difficulty in predicting future earnings. This suggests potential mechanisms through which principles-based accounting standards influence auditors’ risk assessments.

The authors recognize the limitation of this study regarding the sample period. Prior studies compare rules vs principles-based standards by focusing on the differences between US generally accepted accounting principles (GAAP) and international financial reporting standards (IFRS) or pre- and post-IFRS adoption, which raises questions about differences in cross-country settings and institutional environment and other confounding factors such as transition costs. This study addresses these issues by comparing rules vs principles-based standards within the US GAAP setting. However, this limits the sample period to the year 2006 because the measure of the relative extent to which a US firm is reliant upon principles-based standards is available until 2006.

The study has major public policy suggestions as it responds to the call by Jay Clayton and Mary Jo White, the former Chairs of the US Securities and Exchange Commission (SEC), to pursue high-quality, globally accepted accounting standards to ensure that investors continue to receive clear and reliable financial information globally. The study also recognizes the notable public policy implications, particularly in light of the current Chair of the International Accounting Standards Board (IASB) Andreas Barckow’s recent public statement, which emphasizes the importance of principles-based standards and their ability to address sustainability concerns, including emerging risks such as climate change.

The study has major public policy suggestions because it demonstrates the value of principles-based standards. The study responds to the call by Jay Clayton and Mary Jo White, the former Chairs of the US SEC, to pursue high-quality, globally accepted accounting standards to ensure that investors continue to receive clear and reliable financial information as business transactions and investor needs continue to evolve globally. The study also recognizes the notable public policy implications, particularly in light of the current Chair of the IASB Andreas Barckow’s recent public statement, which emphasizes the importance of principles-based standards and their ability to address sustainability concerns, including emerging risks like climate change. The study fills the gap in the literature that auditors perceive principles-based financial statements as less risky and further expands the literature by providing empirical evidence that the likelihood of receiving a going concern opinion is increasing in the degree of rules-based standards.

The purpose of this paper is to ascertain if practising healthy lifestyles improves the technical efficiency of farms in Kwara state, Nigeria. In theory, all deviations from the optimum level of output are due to random effects and inefficiency of producers in which their health plays a key part and is dependent on the kind of lifestyle practiced whether healthy or unhealthy.

Cross-sectional data were employed through a three-staged sampling technique to pick 320 arable crop farmers across the state using a well-defined questionnaire. Data analysis was carried out using descriptive statistics, healthy lifestyles index (HLI), stochastic production frontier (SPF) and propensity score matching (PSM).

First, the analysis showed that about one-third of the sampled arable crop farmers practised healthy lifestyles. Second, the average technical efficiency of arable crop production for farmers who practised a healthy lifestyle was 0.893, and the level of technical inefficiency of the farms was determined by health-related lifestyle status, number of day's illness and educational level. Third, technical efficiency was improved by 0.00431067 for farms whose farmers practised a healthy lifestyle.

Rather than seeing that technical efficiencies of farms are attributed to farm characteristics, inputs used and socioeconomic characteristics alone, the findings suggest that technical inefficiencies of arable crop farmers were also due to the kind of lifestyle practised, which was evidenced in the increased efficiency for farmers who practised healthy lifestyle.

This study investigates the relationship between CEO leadership, gender homophily and corporate environmental, social and governance (ESG) performance. We also investigate whether it is essential to have a critical mass of women directors on the board to create a significant power of gender diversity in leadership positions.

Our study is based on firms listed on the London Stock Exchange (FTSE-All-Share) from 2011 to 2019. CEO characteristics and other board variables were collected from BoardEx, and ESG data, and other related variables were collected from Eikon database.

We find a critical mass of female directors contributes to ESG performance suggesting that token representation of female directors on boards limits their effectiveness. We do not find support for the gender homophily perspective, our findings suggest that the effectiveness of female CEOs does not depend on the existence of a critical mass of female directors. Female directors and female CEOs are less likely to be associated with ESG activities when firms experience poor financial performance. We also find that younger female CEOs have a positive impact on ESG performance. Furthermore, we find female CEOs with shorter tenure are more likely to improve ESG performance. Overall, our findings suggest a substitutional effect between having female CEOs and gender diverse boards.

This study contributes to the debate on gender homophily in the boardroom and how that may affect ESG practices. It also complements existing academic research on female leadership and ESG performance and has important implications for senior management and policymakers.

The authors seek to analyze the impact of weak corporate governance by top executives of a firm on the firm's earnings reports. This research is meant to further emphasize the impact of co-opted executives on a firm, primarily through their impact on earnings management.

Using financial data from 11,473 firm-year observations, the authors utilize ordinary least squares (OLS), 2-stage IV regressions, propensity score matching (PSM) and entropy balancing to analyze the impact of a co-opted top management team on discretionary accruals and restatements.

The authors find empirical evidence that firms with weak corporate governance from top executives are more likely to manipulate reported earnings and have lower financial reporting quality. The authors also find that the effect of co-opted executives on earnings management is weaker when a chief executive officer's (CEO’s) incentives are not aligned with those of top executives, suggesting that executives prevent earnings management due to reputational concerns. Co-opted chief financial officers (CFOs) increase the magnitude of earnings management in a firm but are not solely responsible for the authors' results.

The authors' results suggest that the top executive team provides an important first defense in the prevention of earnings management and corporate wrongdoing. Co-option of the top executive team may be an important consideration when doing research into corporate governance.

This study aims to examine whether the presence of advisory directors affects firm discretionary accruals (DACC), a widely used proxy for financial reporting quality. The authors argue that the advisory director weakens the board monitoring role and impairs the firm financial reporting quality by increasing DACC.

The sample consists of listed firms on the Australian Stock Exchange from 2001 to 2015 using 7,649 firm-year observations. The authors perform descriptive statistics, regression and propensity score matching analyses to examine the research hypothesis.

The research evidence that firms with a higher presence of advisory directors have more DACC, indicating poor financial reporting quality. Furthermore, the authors categorize the DACC and find that the firm has higher income-increasing DACC in the presence of higher advisory directors. The findings are robust concerning endogeneity issues.

The research evidence that firms with a higher presence of advisory directors have more DACC, indicating poor financial reporting quality. Furthermore, the authors categorize the DACC and find that the firm has higher income-increasing DACC in the presence of higher advisory directors. The findings are robust concerning endogeneity issues.

The research contributes valuable insights for regulators and policymakers seeking to comprehend the implications of firms using more advisory directors. Additionally, the authors recognize the potential significance of the findings for the institution of directors, as they can provide a nuanced understanding of the specific roles played by advisory directors in organizational dynamics.

While the extensive body of literature on corporate governance and financial reporting quality has been well-established, a noticeable void exists in academic research delving into the relationship between advisory directors and DACC management. This study seeks to fill this gap, making a distinctive and original contribution to the existing literature on corporate governance.

The relationship between industrial policy and exploratory innovation is imperfect.

The authors use Chinese high-tech enterprise identification policy (HTEP) as a natural experimental group to test policy impacts, spillover effects and mechanisms of action.

First, HTEP promotes exploratory innovation. In addition, HTEP has a greater impact on non-exploratory innovation. Second, HTEP has spillover effects in two phases: HTEP (2008) and the 2016 policy reform. HTEP affects exploratory innovation in nearby non-high-tech firms, and the policy effect decreases monotonically with increasing distance from the treatment group. Third, HTEP affects innovation capacity through financing constraints, technical personnel flow and knowledge flow, which explains not only policy effects but also spillover effects. Fourth, the analysis of policy heterogeneity shows that the 2016 policy reforms reinforce the positive effect of HTEP (2008). By deducting the effects of other policies, the HTEP effect is found to be less volatile. In terms of the continuity of policy identification, continuous uninterrupted identification has a crucial impact on the improvement of firms’ innovation capacity compared to repeated certification and certification expiration. Finally, HTEP has a crowding-out effect in state-owned enterprises and large firms’ innovation.

This paper contributes to the existing literature in several ways. First, the authors enrich the literature on industrial policy through exploratory innovation research. While previous studies have focused on R&D investment and patents (Dai and Wang, 2019), exploratory innovation helps firms break away from the inherent knowledge mindset and achieve sustainable innovation. Second, few studies have explored the characteristics of industrial policies. In this paper, the authors subdivide the sample into repeated certification, continuous certification and certification expiration according to high-tech enterprise identification. In addition, the authors compare the differences in policy implementation effects between the 2016 policy reform and the 2008 policy to provide new directions for business managers and policy makers. Third, innovation factors guided by industrial policies may cluster in specific regions, which in turn manifest externalities. This is when the policy spillover effect is worth considering. This paper fills a gap in the industrial policy literature by examining the spillover effects. Finally, this paper also explores the mechanisms of policy effects from three perspectives: financing constraints, technician mobility and knowledge mobility, which can affect not only the innovation of beneficiary firms directly but also indirectly the innovation of neighboring non-beneficiary firms.

This study aims to explore the moderating effects of strategy on the relationship between working capital management (WCM) and profitability.

A data sample of 72,444 firm-year observations of US-listed firms during 2000–2020 was used. The research hypotheses were tested using a panel regression analysis and an appropriate research instrument that signifies a firm’s strategic positioning.

The prospecting (defending) strategy has a decreasing (increasing) moderating effect on the relationship between WCM and profitability. The empirical findings are not affected by the level of earnings management, the presence of motives to meet earnings targets or the intensity of unreported intangible assets. Additionally, the reported empirical results remain robust within the context of propensity score matching regression analysis, in the presence of nonlinear effects of WCM on profitability, when alternative measures of WCM are used, and between firms with an increase or decrease in future profitability or different levels of efficiency on net WCM investments.

This study may stimulate future research exploring the moderating effects of various variables on the relationship between WCM and operating performance.

The findings highlight the importance of strategy for improving the performance evaluation of WCM policies and the prediction accuracy of the consequences of a strategy on short-term operating performance.

Prior empirical research has documented either a negative or positive relationship between WCM and profitability, which implies the presence of moderating effects of various factors. This study provides empirical evidence of the moderating effects of strategy on the relationship between WCM and profitability.

This study aims to examine whether auditors who specialize in research and development (R&D) activities help reduce managers’ opportunistic adjustment of R&D expenditure for real earnings management (REM).

Using a sample of US firms during the 2001–2017 period, the authors identify auditors’ R&D specialization as their prior experience of auditing R&D expenses spent by each client’s peers. The authors measure R&D-based REM as the negative deviation from the predicted level of R&D expenditure.

The authors find that clients of R&D specialist auditors are less likely to engage in REM through a discretionary reduction of R&D expenditure. This effect is more pronounced when clients face higher competition, have larger investment opportunities and entail higher audit risks.

This study shows that auditors’ specialized knowledge can facilitate stronger monitoring of clients’ real decisions, providing implications for auditors’ knowledge acquisition and transfer in specific types of transactions.

This study contributes to the literature by documenting the governance role played by R&D specialist auditors in clients’ real economic decisions. Moreover, the study identifies R&D as a distinct area of auditor specialization.

This paper aims to examine the effect of corporate social responsibility (CSR) on firm performance (FP) of companies listed on the Tunis Stock Exchange.

This paper reports on two empirical studies. The first was an exploratory qualitative study carried out on a sample of 30 Tunisian companies operating in different sectors. The second empirical study used a panel data regression analysis, to examine data from 46 companies listed on the Tunis Stock Exchange during the 2017 to 2021 period.

The results of the exploratory qualitative study pointed out the specificities of the Tunisian context as to the importance of CSR. The results highlighted also the importance of the 2018 CSR law in Tunisia, yet it drew attention to the non-implementation of its applying texts, meaning that CSR is not always enforced in the Tunisian context. Moreover, in this qualitative study, most companies confirmed that CSR is a key factor behind good governance practices. By studying the impact of CSR on various FP proxies, the results highlight that CSR has a positive and significant impact on FP measured by ROA as an accounting variable and stock returns as a market-measure variable. In addition, the authors confirm the moderating effect of innovation on the CSR and FP relationship. Indeed, innovation affects corporate FP differently. It hinders accounting-based FP while fostering the market-based one.

The study provides insights for managers into how CSR approaches can be used to maximize profits, improve its FP and reputation, while considering the corporate innovative capacities. CSR is a real performance lever for companies, a means of improving their economic, environmental and social efficiency. It enables companies to anticipate constraints and prevent risks, reduce certain operational costs, optimize resources, communicate a good image and stand out from the competition, gain easier access to innovation, strengthen their competitive edge, gain easier access to financing and strengthen their territorial and social roots.

The main contribution of this paper is the adoption of two empirical approaches. These two methods are complementary. The first is an exploratory qualitative approach aimed at better understanding the current state of CSR implementation by Tunisian companies. The second one is quantitative, a panel data regression analysis. Furthermore, the authors test the moderating effect of innovation on the studied link. To the best of the authors’ knowledge, this is the first paper that investigates the moderating effect of innovation on CSR FP in the Tunisian context. Finally, robustness tests were conducted to test the reliability of this study’s results.
