The purpose of this paper is twofold. First, the authors investigate a firm’s decision to provide a CSR report, and if so, whether to have the report assured and to seek higher quality assurance as reflected through the choices of the scope of the assurance and type of assurer, Big 4 accounting firm vs specialist consultant. Second, the authors investigate the impact of voluntary assurance of CSR reports, assurance scope and type of assurer on the likelihood of inclusion in the DJSI and on market valuation.

The study’s sample consists of 17,050 firm-year observations from 40 countries with CSR reports available from Corporate Register and ESG metrics available from ASSET4 over the period 2009–2015. The study first empirically examines the associations between CSR commitment and each of CSR report provision, CSR report assurance, assurance scope and type of assurer. It then examines that association between both inclusion in the DJSI and market valuation with each of CSR report assurance, assurance scope and type of assurer, using inclusion in the DJSI as an objective measure of a firm’s reputation for sustainability given its recognition as a leading indicator for corporate sustainability and market valuation as a reflection of the broader set of capital market participants.

The authors establish two key findings consistent with the predictions of signaling theory. First, we show that high CSR commitment firms are more likely to: provide standalone CSR reports; obtain assurance; obtain assurance from a Big 4 accounting firm; and, adopt higher assurance scope. Second, the authors find that both CSR report assurance and assurance scope increase the likelihood of inclusion in the DJSI, but that the type of assurance provider does not. Alternatively, the authors find that capital market participants appear to value the provision of a CSR report only when it is assured by a Big 4 accounting firm.

The results in the existing literature exploring the capital market benefits to CSR Assurance have been mixed. Firms that voluntarily obtain CSR Assurance incur a cost in doing so and must perceive a net benefit from obtaining such assurance. Despite the limited guidance currently provided by existing CSR standards, we establish the existence of benefits to obtaining CSR Assurance in terms of enhanced likelihood of DJSI inclusion and, more generally, enhanced market valuation. The discussions with DJSI analysts indicate that CSR assurance does enhance the perceived reliability of CSR data, thus improving user confidence.

This paper aims to examine whether capital market rewards firms with good corporate sustainability practices in an international setting by using the Dow Jones Sustainability Index (DJSI hereafter) as an integrated measure of firm sustainability performance.

There are two alternative theories regarding the impact of sustainability on firm value. The value-creating theory predicts that integration of environmental and social responsibility into corporate strategies and practices reduces firm risk and promotes long-term value creation. The value-destroying theory on sustainability suggests that managers may engage in socially responsible activities at the expense of shareholders. To perform empirical tests, we use a large international sample for a period of 13 years between 1999 (the first year when DJSI became available) and 2011. To control for self-selection bias and simultaneity, the authors use lagged values of sustainability performance in a robustness check.

The authors find a positive relation between sustainability performance and firm value, after controlling for variables that have been found to affect firm value in the existing literature. The test results are consistent with the value enhancing theory (as opposed to the shareholder expense theory) regarding the role of sustainability engagement in firm valuation. Furthermore, the positive impact of sustainability engagement on firm value is primarily driven by countries with strong investor protection and with high disclosure levels.

A positive impact of sustainability performance on firm value supports the value-creating theory and rejects the value-destroying theory. Test results also suggest a more pronounced market response to corporate sustainability in countries with stronger shareholders protection and higher requirement for financial transparency.

Given the growing international capital market and intensifying global competition, the valuation implications of sustainability in an international context is of practical interest to management, investors and regulators worldwide.

First, it is an initial attempt to test an integrated measure of the “triple-bottom-line” definition of sustainability in an international setting. Second, our paper studies the international variation in market valuation of firm sustainability performance in terms of the value enhancing versus shareholder expense theories on sustainability. The authors explore the relevance of sustainability performance in relation to the investor protection and the reporting environment across countries.

The purpose of this paper is to statistically assess the relationship between corporate characteristics, environmental contribution and financial performance. To this end, the authors compare the financial performance of all US corporations making up the Dow Jones Sustainability Indexes, being the most proactive companies in providing services and goods, while maintaining ethical responsibility and environmental sustainability.

Various performance measures are compared to the mean performance of the related industry, sector and market portfolio. We employ an analysis for several time horizons of the financial measures.

Analysis by the authors suggests that firms that are proactive in supporting social responsibility and environmental sustainability (SRES corporations) are characterized by significantly higher profit measures than the industry and the sector, though not higher than the entire market. They have lower short-term liquidity measures than those of the industry and related sector, and surprisingly, their long-term leverage is significantly higher. Strong SRES corporations are characterized by significantly higher managerial efficiency ratios than the respective industry and sector. Interestingly, however, the per-worker operating efficiency ratios are significantly lower than for all of the benchmarks.

The revealed preference of corporations can be extracted from several horizon dependent financial measures. For instance, we could infer the corporate degree of SRES from their long-term capital structure, i.e. their long-term leverages and short-term liquidity measures.

These results illustrate the strong relation between social and environmental sustainability, and long-term business plans in respect to the corporate capital structure.

This study aims to examine the attractiveness of the regional Dow Jones Sustainability Indexes (DJSI) and several renewable energy indexes during December 31, 2010 to December 31, 2019. This study uses a risk-return analysis and a set of explanatory factors. Lastly, this study conducts a comparative analysis of these indexes with conventional indexes.

This study uses data from Eikon, a Thomson Reuters database. To analyze the indexes’ behavior, this study uses the indexes’ annual return as of December 31 for each year. Next, this study estimates the Fama and French’s five-factor model using an ordinary least squares regression for regional DJSI and renewable energy indexes.

The results show that regional DJSIs delivered returns both above and below conventional indexes. In contrast, renewable energy indexes had high betas and negative returns, making them unattractive to investors.

The results imply the need for public financing programs that support the transition to a sustainable economy and reduce risk and increase the return on private investment.

This study provides insights for policymakers regarding the importance of sustainability indexes in the transition to a green economy.

This study contributes to the growing literature on Fama and French’s five-factor model of sustainability indexes, especially in the current context characterized by intense green political changes. In particular, this study complements the few studies that have addressed the economic implications of renewable energy indexes in markets.

Although an extensive body of research treats the fields of corporate governance and sustainable development separately, less attention has been paid to the interaction between both fields. This paper attempts to bridge this gap by examining how corporate governance systems are evolving in order to integrate sustainable development thinking into them.

Drawing from corporate governance, sustainable development, and stakeholder theory literature, an analysis is performed of the governance systems of the 18 corporations that are leading the market sectors considered by the Dow Jones Sustainability World Index.

The results of our in‐depth analysis of the 18 cases are presented and the sustainable corporate governance model that emerges from that analysis is proposed.

This model does not attempt to question or replace the previous recommendation and frameworks suggested in the literature on corporate governance and codes of governance. On the contrary, the model should be viewed as a way of integrating sustainable development/corporate responsibility into the fabric of already existing governance models suggested elsewhere.

The suggested model seems to be a good framework both for managers and for researchers because it can be used to improve the firm's governance systems as well as a guide for future research on sustainable corporate governance.

The purpose of this paper is to compare the sustainability disclosure methods‐instruments practiced by the two most widely employed indexes/instruments (DJSI World and GRI‐G3 Guidelines). The paper suggests that the newly created triple bottom line (TBL) reporting practices need to undergo further standardization and enforcement to avoid, or give early warnings about, future corporate mismanagement that leads to socio‐economic consequences detrimental to investors and consumers in general.

This paper utilizes sample firms from the DJSI World Index and the GRI‐G3 Sustainability Guidelines membership list to draw inferences on sustainability indicators of performance. The authors compare the GRI reporting guidelines with the disclosure indicators of the DJSI World.

The authors' findings suggest that TBL reporting has made enormous progress over the last two decades. However, the two widely used sustainability reporting instruments/indexes (DJSI World and GRI‐G3 Guidelines) differ in disclosure practice‐methods and the authors recommend that further standardization and enforcement is necessary. The authors' view is that the Securities and Exchange Commission (SEC) and Financial Accounting Standards Board (FASB) should become actively involved with the issue of standardization and enforcement of corporate socio‐environmental disclosures. The paper presents evidence that investors have neither rewarded nor penalized firms for adhering to or violating sustainability matters in their corporate decisions.

The authors argue for further standardization and enforcement with regard to the disclosure methods of the two widely used (GRI and DJSI) sustainability indicators in order to avoid future corporate mismanagement that leads to (systemic) economic and socio‐environmental consequences detrimental to citizen investors and consumers in general.

The research is of interest to academicians and practitioners who are interested in the theory and practice of sustainability reporting or TBL reporting. The findings suggest that this newly created disclosure instrument needs to undergo further standardization and enforcement for meaningful and accurate disclosure of economic‐social and environmental performance. The authors' view is that the SEC and FASB should become actively involved with the issue of standardization and enforcement of socio‐environmental disclosure of corporate sustainability.

This study aims to examine the relationship between corporate social responsibility (CSR) award and sustainability assurance levels for the French CAC 40 companies.

A sample of 57 French companies in the CAC 40 index corresponding to 448 observations was analyzed between 2008 and 2020 using an ordinal regression.

The main results conclude that the inclusion in the Dow Jones Sustainability Index World, the CSR award and the introduction of the Grenelle 2 law have a significant influence on sustainability assurance levels. However, incentive compensation does not appear to be relevant to explain sustainability assurance levels.

The present study focuses on a sample, limited to companies belonging to the CAC 40 index. To enhance the understanding of sustainability assurance levels, this research may include other global sustainability indices, such as the MSCI World and the FTSE4Good World, in the CSR awards.

This study could be useful for audit practitioners, leading them to reconsider their evaluation methods and take into account CSR incentives for a more objective analysis. Regulators should investigate the current CSR issues to improve CSR disclosure standards. Finally, these findings could motivate other researchers to expand the scope of the research to diverse contexts.

This study helps fill the gap existing in sustainability assurance literature by highlighting the relationship between CSR rewards and sustainability assurance levels.

The purpose of this paper is to present the Islamic stock and Sukuk market efficiency and focus on the presence of investor herding behaviour (HB) captured by Hurst exponent estimation.

The Hurst exponent was estimated with various methods. The authors studied the evolving efficiency of the “Dow Jones” indices from 1 January 2010 to 30 December 2016 using a rolling sample of the Hurst exponent. In addition, they used a time-varying parameter method based on the Hurst of delayed returns. After that, the robust Hurst method was considered. In the next step, the efficiency of the different activity types of Islamic bonds was studied using an efficiency index. Finally, the Hurst exponent estimates were applied to assess the presence of HB.

The results show that, firstly, there’s a strong correlation between the “DJIM” and “DJSI” prices and returns. Secondly, by using robust Hurst estimate, it is observed that the “DJIM” is the most efficient market. The Hurst exponent estimation results show that HB is more intensive in the Islamic stock market. These results indicate also the inexistence of this behaviour in the studied Sukuk market.

Sukuk as Islamic financial assets is recent. Their relative time series are not long enough to apply the long memory approach. Furthermore, this work can be extended to study other Islamic financial markets.

Herding affects risk-return characteristics of assets and has an impact on asset pricing models. Practitioners are interested in understanding herding and its timing as it might create profitable trading opportunities.

This work analyses the impact of Islamic principles on the financial markets and their ability to understand some behavioural biases.

This study contributes to the literature by identifying the efficiency and the presence of HB with Hurst exponent estimation in Islamic markets.

This study aims to conduct an empirical investigation to assess the hedge, diversifier and safe-haven properties of different environmental, social and governance (ESG) assets (i.e. green bonds and ESG equity index) vis-à-vis conventional investments (namely, equity index, gold and commodities).

The authors examine the sample period 2007–2021 using the bivariate cross-quantilogram (CQG) analysis and a dynamic conditional correlation (DCC) multivariate generalized autoregressive conditional heteroskedasticity (GARCH) experiment with several extensions.

The evidence shows that the analyzed ESG investments exhibit mainly diversifying features depending on the asset class taken as a reference, with some potential hedging/safe-haven qualities (for the green bond) in peculiar timespans. Therefore, the results suggest that investors might consider sustainable investing as a new measure of risk reduction, which has interesting implications for both portfolio allocation and policy design.

To the best of the authors’ knowledge, this study is the first that empirically investigates at once the dependence between different ESG investments (i.e. equity and green bond) with different conventional investments such as gold, equity and commodity market indices over a large sample period (2007–2021). Well-suited methodologies like the bivariate CQG and the DCC multivariate GARCH are used to capture the spillover effect and the hedging/diversifying nature, even in temporary contexts. Finally, a global perspective is used.

The organizational ecology perspective approaches the integration of sustainability into the accounting curriculum by following the evolutionary process of organizational development. There is a growing interest in sustainability, and, recently, books and articles have appeared that discuss sustainability accounting and reporting. A number of schools have developed standalone courses in sustainability accounting while others have integrated sustainability into existing courses in accounting ethics or corporate social responsibility. This chapter applies ecological, both organizational sociological and anthropological, approaches to argue in favor of integration of sustainability into the accounting curriculum rather than in standalone courses. These two approaches are utilized because these disciplines have well-established theoretical and methodological approaches that can be applied to study the subject of sustainability, natural resources conservation, and ecological management. In addition, the current trend in accounting education is for the incorporation of social and behavioral sciences perspectives, including sociology and anthropology, into the accounting curriculum. Accordingly, the application of the ecological approach from these disciplines contributes significantly to the study of the integration of sustainability into the accounting curriculum.
