The value relevance of SAM's corporate sustainability ranking and GRI sustainability reporting in the European stock markets

This paper investigates whether relative corporate sustainability as measured by the SAM sustainability ranking and sustainability reporting in terms of Global Reporting Initiative (GRI) application levels are associated with a higher market valuation. We conduct a value relevance study for the 600 largest European companies with the Feltham and Ohlson valuation model as a reference point. Our results indicate that for the observation period 2001 to 2011, the association between corporate sustainability and market value is positive. The empirical evidence of a positive relationship between GRI reporting and market value is statistically significant in some but not all of the model specifications. We find no evidence of interaction between the value relevance of corporate sustainability and sustainability reporting, nor do we find any positive effect of external assurance on the capital market perception of GRI application levels. Our results support the notion that conducting business in accordance with ethical norms is also a shareholder value‐increasing business strategy. However, it is not possible to verify the information given in sustainability reports through external assurance.     

Governance Structure and the Credibility Gap: Experimental Evidence on Family Businesses’ Sustainability Reporting

This paper examines the success of corporate communication in voluntary sustainability reporting. Existing studies have focused on the perspective of the communicators but lack an understanding of the perspective of information recipients to clearly evaluate this interactive communication process. This paper looks at the issue of a credibility gap perceived by external stakeholders when they doubt the authenticity of communicated information due to the reporting company’s governance structure. The paper uses family businesses to exemplify the emergence of such a gap when outsiders become concerned about the potential agency problem of the integrated ownership and management controlled by a few members of the same family. Following source credibility theory, these concerns raise a credibility gap associated with a family firm’s trustworthiness and goodwill, even if the family has the expertise to carry out sustainability reporting. The findings of two experimental studies indicate that family businesses suffer a greater credibility gap than non-family businesses. An external and independent assurance service can mitigate such gaps, especially when the service is comprehensive and targets family businesses. The paper provides a complete view evaluating corporate communication by looking at the interaction between the communicating company and the information recipients.     

Sustainability assurance and cost of capital: Does assurance impact on credibility of corporate social responsibility information?

This paper aims to examine the credibility value of sustainability assurance and the type of assurance provider on cost of capital. A large sample of international companies from the period 2007–2014 was used to develop our models of analysis. We find a greater decrease in cost of capital for companies that publish and assure their social and environmental reports. Thus, voluntary sustainability disclosures decrease the cost of capital. However, companies also have the opportunity to reinforce this decrease by providing an assurance statement, so increasing the credibility of corporate social responsibility information. In addition, the decrease in the cost of capital is significantly higher when such assurance is provided by a top‐tier accountancy firm instead of by engineering or consultancy firms; this result supports also the reputational capital of accountancy firms.     

Coercive,normative and mimetic isomorphism as determinants of the voluntary assurance of sustainability reports

This study offers an opportunity to understand how country- and industry-specific effects may affect the decision to assure sustainability reports by identifying institutional pressures. Based on neo-institutional theory, the aim of this research is to highlight whether assurance derives from the coercive, normative and mimetic forces related to legal and cultural strength and the industry pressure for assurance, respectively. The panel data analysis of an international sample of 696 companies for the period 2007–2014 shows that voluntary assurance acts as a legitimization tool implemented by companies in response to normative, coercive and mimetic pressures; that is, companies operating in countries that have a greater legal system and cultural development, especially in industries that are greatly concerned about sustainability, are more likely to issue an assurance statement. Moreover, through a two-stage logit model, we respond to the question of which is the relevant institutional factor that causes voluntary assurance to be adopted. Specifically, we evidence that the normative factor is the one that exerts the greatest explanatory power in the assurance demand, followed by coercive pressure.     

The Role of Stakeholders in Sustainability Reporting Assurance

The main purpose of this exploratory analysis is to understand whether, based on evidence gathered from international best practices selected among corporations which adopt the Global Reporting Initiative guidelines in sustainability reporting (SR), stakeholders are significantly consulted and involved—as international literature would indicate—by assurance providers, during assurance processes of SR. We aim at verifying if this practice—known as stakeholder assurance—is in fact widespread in SR assurance by carrying out empirical research, through content analysis, into a sample of 161 assurance statements of international corporations, in order to test characteristics of any stakeholder assurance implemented.     

Customers' cognitive patterns of assurance: a dual approach

Assurance has been identified as a key service quality dimension but has not attracted theoretical and empirical attention on a distinct basis. The present pilot study adopts both qualitative and quantitative methods to look at how distinct customer groups (internal and external) perceive assurance in particular when they evaluate service quality. Evidence comes from 83 individuals of the medical staff and 79 patients at an outpatient unit. The novelty of the present study lies in the combination of means–end analysis with a probabilistic model to ground the conceptually appealing composite structure of assurance on a more concrete attribute foundation. Findings suggest that while the groups under investigation realize different benefits in achieving assurance, they share a common guide when prioritizing service-related attributes, namely the professional capacity of personnel. Overall, assurance proves itself to be critical, at least for the healthcare sector.     

The Level of Sustainability Assurance: The Effects of Brand Reputation and Industry Specialisation of Assurance Providers

This research focuses on examining the relationship between some attributes of assurance providers and the level of sustainability assurance. By using the propensity to issue negative conclusions in the assurance statement as an indicator of the level of assurance, we examine whether the brand name and industry specialisation of the practitioners have an impact on the assurance opinion issued. Using an international sample of 1233 firm-year observations over the period 2007–2014, the findings document the impact of the brand reputation and industry specialisation of assurance providers on the level of assurance. The probability of detecting material errors and omissions in a sustainability report is higher if it is verified by a Big 4 auditing firm and by an industry expert as an assurance practitioner. The greater experience in providing audit services and the relevant skills and training provided by Big 4 firms, as well as the greater knowledge and experience of industry experts, increase the propensity to report more accurate opinions about a sustainability report. The findings are robust for alternative measures for the level of assurance and the industry specialisation.     

How capital markets assess the credibility and accuracy of CSR reporting: Exploring the effects of assurance quality and CSR restatement issuance

This research examines how the credibility and accuracy of corporate social responsibility (CSR) disclosures enhance market confidence by exploring their effect on the cost of capital. How do capital markets react to higher-quality assurance of CSR reporting? Can the hypothetical reduction in the cost of capital that assurance quality produces be explained by restatements of previous information given in these CSR reports? We explore the relationship between assurance quality, as a proxy for credibility and market confidence, and the mediating effect of CSR restatements as indicators of accuracy. We propose regression models with a sample of CSR reports issued by European companies. Building upon the signalling and legitimacy theories, the results support the positive effect of higher assurance quality statements on market confidence by confirming a decrease in the cost of capital; assurance quality gives an indication of credibility to the capital market and restatements related to methodological updates signal accuracy. The reduction in the cost of capital brought on by higher assurance quality appears to be determined by the issuance of CSR restatements, which create legitimacy for both client companies and assurance providers. CSR reporting and assurance have reached a greater level of maturity as demonstrated by the evolution of these practices and financial market perceptions.     

Assurance of corporate social responsibility reports: Does it reduce decoupling practices?

Recent research shows the existence of a selective corporate social responsibility (CSR) disclosure strategy that creates a gap between CSR disclosure and actual performance. These CSR decoupling practices compromise the credibility of CSR reports and have triggered a demand for the adoption of credibility enhancement mechanisms, such as adherence to the global reporting initiative (GRI) reporting guidelines, and the external assurance of CSR reports. The effectiveness of such mechanisms is not clear, however. This paper draws on legitimacy theory and addresses the issue of symbolic versus substantive use of assurance, and compliance with GRI reporting standards, by analysing their effect on CSR decoupling using an international sample of 1,939 companies (15,219 observations from 2002 to 2017). Analysis of a sub-sample of 708 firms (3,730 observations from 2011 to 2017) also shows that the application of GRI guidelines and the specific characteristics of the assurance provider—accountant, experience and specialisation—reduce CSR decoupling practices. The results provide researchers, managers, assurance providers, investors, stakeholders and regulators with additional insight into the value of the external assurance of sustainability reports and have important managerial and policy implications.     

The role of art infusion in enhancing pro-environmental luxury brand advertising

Underpinned by art infusion theory, this present research examines the effect of art infusion on brand attitudes under different brand conditions (i.e. pro-environmental luxury brands and luxury brands) in advertising. Across two experimental studies, this research offers empirical evidence to a moderated mediation model, such that when an advertisement features an artwork (vs. no-artwork), consumers will perceive lower levels of incompatibility between luxury and sustainability, leading to a more favorable brand attitude toward the pro-environmental luxury brand. However, such differences will not occur among consumers evaluating an ordinary luxury brand. The findings of this research broaden the current body of knowledge related to the art infusion effect and provide important implications for marketers in their advertising strategy. Furthermore, these findings suggest that art infusion may be the solution to the dilemma facing sustainable luxury brands since luxury and sustainability are often perceived as incongruent concepts.

Complex services and choice criteria: an example from the life assurance market

This study analyses customer choice criteria in the context of a complex service, more specifically, endowment life assurance policies. The study draws upon previous literature which has suggested that service complexity may have implications for consumer behaviour in general and customer choice criteria in particular. A quantitative study is employed to investigate the relative importance of choice criteria in endowments and differences in importance with respect to various demographic and related factors. Findings indicate that the consumer's choice of institution is most often influenced by use of an existing service with that firm, followed closely by choosing on the basis of recommendation or family relationship. Factors such as performance and charges are shown to be relatively unimportant choice criteria. In addition, differences in the importance of choice criteria with respect to gender, class, household income, educational attainment, age and financial maturity are apparent.     

Investigating when religious culture increases trade credit: A signaling theory approach

Drawing on signaling theory, we propose that religious culture leads suppliers to alter their beliefs about their customers’ trustworthiness. Strong religious cultures are interpreted as a signal of fewer agency problems and less information asymmetry, which helps firms gain more trade credit from suppliers. The empirical tests performed in this study show that firms headquartered in areas with strong religious cultures receive more trade credit than other firms. This positive relation is more prominent when such firms are located in areas with lower levels of social trust. A further analysis reveals that the increasing effect of religious culture on trade credit eases financing constraints. Overall, our findings indicate that religious culture can be a broad indicator of firms’ ethical preferences that influences their access to trade credit by signaling their potential for a high level of trustworthiness.     

Corporate social responsibility and bank risk profile: evidence from Europe

This study analyzes the impact of risk profile on sustainability reporting and its quality in European banks. Financial institutions (FI) play a social role in the financial inclusion process and incorporate environmental considerations into credit risk assessment, making corporate social responsibility (CSR)-related issues vital for risk management systems. FI with lower capital risk, higher liquidity risk, higher profitability in banking, and higher sensitivity to market risk tend to issue CSR reports. The findings suggest that FI with lower profitability in banking disclose higher quality CSR financial services sector (FSS)-specific information, whereas FI not submitting CSR reports for external assurance or having their CSR reports assured by certain auditors issue lower quality CSR/FSS-specific information.     

Mandatory Corporate Social Responsibility (CSR) Reporting and Financial Reporting Quality: Evidence from a Quasi-Natural Experiment

This study examines the impact of mandatory Corporate Social Responsibility (CSR) reporting on firms’ financial reporting quality using a quasi-natural experiment in China that mandates a subset of firms to report their CSR activities starting in 2008. We find that mandatory CSR disclosure firms constrain earnings management after the policy. The result is robust to a battery of sensitivity tests and more prominent for firms with lower analyst coverage. Further analyses reveal that upward earnings management by mandatory disclosure firms is more likely to be caught after the policy. The findings suggest that mandatory CSR disclosure mitigates information asymmetry by improving financial reporting quality.     

The impact of reporting frequency on the information quality of share price: evidence from Chinese state-owned enterprises

As a major global exchange, the Stock Exchange of Hong Kong (SEHK) only requires semi-annual reporting whereas other major exchanges including the ones in Chinese mainland require quarterly reporting. We argue against the traditional view that higher reporting frequency is necessarily more beneficial. The decision on reporting frequency depends on how the information is being processed by the recipient traders and the results are not obvious. Using a sample of Chinese companies duallisted in both China A share market and SEHK (AH shares) as the experimental group and mainland’s companies listed on SEHK (H shares) only as the control group, we apply the difference-in-difference (DID) method to investigate the impacts of reporting frequency on stock information quality. The results suggest that after China A share market require quarterly financial reporting for all listed companies in 2002, the information asymmetry of the H tranche of AH stocks increases. Different from prior studies, the results suggest a negative association between stock information quality and financial reporting frequency. We argue that the increased information asymmetry in the H tranche is caused by the noise spilled over from the A tranche. We conduct multivariable GARCH tests and find evidence supporting this conjecture.

Defining the Content of Sustainability Reports in Nonprofit Organizations: Do Stakeholders Really Matter?

The aim of the article is to investigate the role of stakeholder engagement and participation in nonprofit organizations’ sustainability reporting, according to the literature on third sector and stakeholder theory. To verify the levels of involvement, the authors conducted an empirical survey, using content analysis, on a sample of 54 sustainability reports of nonprofit organizations included in the Global Reporting Initiative database as of September 1, 2012. In order to strengthen the results obtained from the content analysis, the authors shared their findings with the organizations of the sample. The survey showed that there were some criticisms regarding stakeholder participation in the targeted research field. These are considered in the conclusions. Questions for the future included whether stakeholder engagement is moving from being simply a way to consult and influence stakeholders to being an effective instrument for involving them in nonprofit organizations’ reporting and decision-making processes, through mutual commitment.
