This study aims to assess the informativeness of carbon emission data for the stock markets and the mediating role played by financial analysts and the quality of the governance on this issue.

Relying on structural equation modelling, the authors assess the relation between embedded CO₂ disclosure or CO₂ emissions disclosure and the stock market valuation (Tobin Q), considering the mediating roles played by financial analysts (external monitoring) and corporate governance (internal monitoring).

Results based on a sample of North American firms in the oil and gas industry are the following. The disclosure of embedded CO₂ is negatively associated with a firm’s market value, but this association is mediated by analyst following and corporate governance. The disclosure of yearly CO₂ emissions is also negatively related to stock market value, while corporate governance mediates this negative impact, and analysts following does not. Considering that yearly CO₂ emissions represent short-term environmental risks, whereas embedded CO₂ represents long-term environmental risks, it appears important to consider embedded CO₂ when studying the impact of carbon disclosure on firm value. The authors also show that a firm’s environmental performance (measured by Carbon Disclosure Project – CDP) is positively associated with two mediating variables (i.e. analyst following and corporate governance).

The study results suggest that CO₂ emissions information is less relevant than embedded CO₂ in attracting financial analysts when they are assessing a firm’s value because it represents short-term environmental risks, whereas embedded CO₂ represents long-term environmental risks. Therefore, the authors consider important to include embedded CO₂ when studying the impact of environmental disclosure on a firm’s value.

The study investigates the relevance for stock markets of voluntary disclosure of eXtensible Business Reporting Language (XBRL) extensions [based on International Financial Reporting Standards (IFRS) or US-GAAP] for an international sample of US cross-listed firms.

The study examines if the disclosure of XBRL extensions by a firm provides relevant information to market participants. Towards that end, this paper investigates whether this type of disclosure affects the level of information asymmetry between insiders and investors and if it is value relevant. This study measures information asymmetry by bid-ask spread and value relevance by stock price or Tobin's Q.

After a certain level of disclosure of XBRL extensions, the impact on stock pricing is negative (creates noise on stock markets). Controlling for that phenomenon, both IFRS and US-GAAP XBRL extensions are value relevant. Second, results indicate that XBRL extensions are positively (negatively) related to stock market value for firms that exhibit positive (negative) earnings. This suggests a complementary effect between earnings and XBRL extensions on their relation with stock price or Tobin's Q. Finally, the results also indicate that both IFRS extensions and US-GAAP extensions are associated with lower information asymmetry (i.e. bid-ask spread).

To the best of the authors’ knowledge, this study is the first to investigate the relevance of XBRL extensions under IFRS for US cross-listed firms since the availability of the IFRS taxonomy for foreign private issuers that prepare financial statements under IFRS standards.

The authors assess the informativeness for stock markets of proven reserves of oil and gas, and embedded CO₂ in those reserves.

Based on a two-step regression approach, the authors attempt to test the relationship between proven reserves, CO₂ embedded in those reserves and the stock market value controlling for the selection bias (i.e. the decision of managers to disclose environmental information about embedded CO₂).

Results, based on a sample of the US and Canadian firms are the following. Proven reserves increase the firm’s value, while embedded CO₂ reduces the stock market value substantially. Furthermore, the decision of managers to disclose information about embedded CO₂ is positively related to analyst following, share price volatility, firm size, and institutional ownership.

The current study assesses the long-term incidence of embedded CO₂ (in oil and gas proven reserves) on firms’ stock market value, while most studies are focusing on yearly CO₂ emissions.

This article aims to explore whether a firm's corporate social responsibility (CSR) transparency alleviates a firm's cash holdings.

CSR transparency ratings encompass both the quantity and the quality of CSR practices, as validated by Bloomberg. While based upon firm-specific disclosure, transparency ratings impound additional information gathered independently by Bloomberg and thus bridge the gap between CSR disclosure and CSR performance. The authors use ordinary least squares estimators, and the authors concentrate on a panel of S&P 500 index companies over the period of 2012–2018 to examine the effect of CSR transparency on corporate cash holdings.

The authors document that a higher level of CSR transparency induces a lower level of corporate cash holdings. Additional results imply that this negative relationship is more pronounced for firms suffering from high information asymmetry, with low financial reporting quality and for those with weak governance. Further analyses document that higher CSR transparency can help firms to enjoy lower cost of debt and to be less financially constrained, enabling high CSR transparent firms to obtain external financing more easily and at a lower cost, thus lowering the need to hoard cash. Ultimately, the study findings suggest that CSR transparency increases the market value relevance of an additional dollar in cash holdings.

The authors contribute to both research streams of CSR and corporate cash holdings as they provide evidence about the influence of CSR transparency as a monitoring and insurance-like mechanism on corporate cash holdings.

The purpose of this paper is to investigate whether formally disclosing an earnings before interests, taxes, depreciation, and amortization (EBITDA) number reduces the information asymmetry between managers and investors beyond the release of GAAP earnings. The paper also assess if EBITDA disclosure enhances the value relevance and the predictive ability of earnings.

The authors explore the interface between GAAP and non-GAAP reporting as well as the impact of corporate governance on the quality of non-GAAP measures.

Results suggest that EBITDA reporting is associated with greater analyst following and with less information asymmetry. The authors also document that EBITDA reporting enhances the positive relationship between earnings and stock pricing as well as future cash flows. Moreover, it appears that corporate governance substitutes for EBITDA reporting for stock markets. Hence, EBITDA helps market participants to better assess earnings valuation when a firm’s governance is weak. Inversely, when governance is strong, releasing EBITDA information has a much smaller impact on the earnings-stock price relation.

The authors revisit the issue of how corporate governance relates with earnings quality by considering the potentially confounding effect of EBITDA reporting; it appears that such reporting substitutes for governance in moderating the relation between governance and earnings quality.

This study aims to assess if the voluntary reporting of adjusted earnings before interest, taxes, depreciation and amortization (EBITDA), a widely used non-generally accepted accounting principles (GAAP) measure, has effects on information asymmetry and value relevance and how the adjustments to GAAP earnings made to derive it contribute to these effects. This study focuses on firms from two countries with contrasting institutional settings, Canada and France.

Relying on multivariate analyses and using Heckman’s procedure to address the sample self-selection issue, this study first estimates the likelihood of a firm to report adjusted EBITDA. Then, this study examines if adjusted EBITDA, as well as the adjustments made to GAAP earnings to derive adjusted EBITDA (adjustments), affect a firm’s information asymmetry and its value. These adjustments are essentially GAAP-grounded items that are discarded by management to derive non-GAAP adjusted EBITDA. The dependent variables are share price volatility, as a proxy for information asymmetry, alongside market-to-book and stock market return as indicators of value.

In terms of the used sample, results suggest that Canadian firms are much more likely to report adjusted EBITDA than French firms. Chief executive officer (CEO) attributes (CEO power) appears to increase such likelihood. Moreover, for both Canadian and French firms, adjusted EBITDA is associated with reduced stock market volatility, an indication of lower information asymmetry, as well as higher market-to-book and returns, suggesting value relevance. The results also indicate that investors view the adjustments to GAAP earnings made by management to derive adjusted EBITDA as not value relevant (similar to noise). The GAAP-grounded elements that management discard to derive adjusted EBITDA actually increase information asymmetry.

This study adds to prior research on the interface between a CEO attributes and governance and non-GAAP reporting. This study also provides evidence that, despite very different institutional settings, non-GAAP reporting conveys relevant information to capital markets’ participants in both France and Canada. Hence, a country’s institutional setting may have a differential impact on the disclosure choice but not on the resulting value relevance of such disclosure. Finally, this study extends the non-GAAP literature by examining the value relevance of a widely used yet under-researched measure, adjusted EBITDA.

The aim of the paper is to investigate whether social disclosure and environmental disclosure have a substituting or a complementing effect in reducing information asymmetry between managers and stock market participants

This study attempts to provide a comprehensive analysis of a firm's social and environmental disclosure strategy. The authors posit that this strategy simultaneously affects information asymmetry and disclosure.

Findings suggest that social disclosure and environmental disclosure substitute each other in reducing stock market asymmetry.

The measurement of social and environmental disclosure is based upon a coding instrument that makes some explicit assumptions about the value and relevance of information. Moreover, information asymmetry cannot be directly measured and is inferred from the behaviour of proxy variables such as share price volatility and bid‐ask spread.

Results suggest that social disclosure reinforces the informativeness of environmental disclosure for stock markets, even substituting for it under certain conditions. Stakeholders must assess and retain an increasing flow of information: a more efficient disclosure strategy becomes critical if firms want to convey the right picture of their CSR performance.

To the best of the authors' knowledge, this is the first study to explore the joint effect of social disclosure and environmental disclosure in reducing information asymmetry.

The purpose of this paper is to assess if a firm’s ethical lapses, which result from unethical behavior or actions, influence its social disclosure (SD) practices as well as how ethical lapses affect both the firm’s legitimacy within society and its standing in financial markets. This study addresses two-related questions: do a firm’s ethical lapses undermine the credibility of its SD in financial markets, either directly or through a firm’s legitimacy? Do ethical lapses affect a firm’s market value and is this effect mediated by SD and legitimacy?

Three hypotheses are derived based on two theoretical approaches, information economics and institutional theory. The hypotheses lead ultimately to an examination of a firm’s legitimacy. Ethical lapses are inspired by the Global Reporting Initiative grid and by ISO 26000.

The results suggest that a firm’s ethical lapses underlie its SD practices and affect its legitimacy and standing in financial markets, the latter being proxied by financial analysts’ forecasts.

The limitations of this study include that alternative ways exist to measure the constructs employed, the measurement of SD is subject to discretionary choices, and the North American sample results may not be generalizable to other countries.

The originality and contributions of this study are based on the use of information economics and institutional theory in a complementary way that recognizes information as serving various purposes and constituencies. Additionally, the paper extends prior research on the SD aspects of CSR by showing it matters to both financial markets and non-financial stakeholders.

The purpose of this paper is to explore the relationships between corporate social responsibility (CSR) disclosure, corporate governance and financial analysts’ information environment, as proxied by their ability to forecast a firm’s earnings. Hence, we extend prior voluntary disclosure research.

Our paper considers that the determination of CSR disclosure, corporate governance and financial analyst forecasting work are closely intertwined. Therefore, we rely on simultaneous equations to explore these relations.

Findings show that there is a direct relation between both CSR disclosure and corporate governance and financial analysts’ information environment: more disclosure and better governance translate into a tighter consensus in earnings forecasts as well as less dispersion. However, corporate governance substitutes for CSR disclosure in improving analyst forecast precision, thus supporting a comprehensive view of corporate governance that encompasses disclosure. Finally, results also suggest that CSR disclosure, through its effect on governance and analyst following, has an indirect influence on analyst forecast precision. Overall, it appears that both CSR disclosure and good corporate governance attract analysts and improve their ability to forecast earnings.

To the best of our knowledge, our study is the first to investigate the joint effect of corporate governance and CSR disclosure on analyst forecast precision.

The study aims to identify and discuss influential aspects of corporate environmental disclosure (CED) literature, including key streams, themes, authors, keywords, journals, affiliations and countries. This review also constructs agendas for future CED research.

Using a bibliometric review approach, the authors reviewed 560 articles on CED from 215 journals published between 1982 and 2020.

The authors' insights are three-fold. First, the authors identified three core streams of CED research: “legitimization of environmental hazards via environmental disclosures,” “the role of environmental accounting in achieving corporate environmental sustainability” and “integrating environmental social and governance (ESG) reporting into the global reporting initiatives (GRI) guidelines”. Second, the authors also deployed a thematic map that classifies CED research into four themes: niche themes (e.g. institutional theory and environmental management system), motor themes (e.g. stakeholder engagement), emerging/declining themes (e.g. legitimacy theory) and basic/transversal themes (e.g. voluntary CED, environmental reporting and corporate social responsibility). Third, the authors highlighted important CED authors, keywords, journals, articles, affiliations and countries.

This study assists researchers, journal editors and consultants in the corporate sector to comprehensively understand various dimensions of CED research and practices and suggests potential emerging research areas. Although this paper appears to have been thoroughly conducted, using authors' keywords to identify themes was a key limitation. Thus, the authors call upon using a more comprehensive data mining technique that uses keywords in abstracts, titles and the whole body of papers and then identifies inclusive trends in CED literature.

The authors contribute to the extant accounting literature by investigating the organizational-level CED, both mandatory and voluntary, using a systematic and bibliometric literature review model to summarize the key research streams, themes, authors, journals, affiliations and countries. By doing so, the authors construct a future research agenda for CED literature.
