This study investigates information flow of market constituents and global indices at multi-frequencies.

The study’s findings were obtained using the Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (I-CEEMDAN)-based cluster analysis executed for Rényi effective transfer entropy (RETE).

The authors find that significant negative information flows among sustainability equities (SEs) and conventional equities (CEs) at most multi-frequencies, which exacerbates diversification benefits. The information flows are mostly bi-directional, highlighting the importance of stock markets' constituents and their global indices in portfolio construction.

The authors advocate that both SE and CE markets are mostly heterogeneous, revealing some levels of markets inefficiencies.

The empirical literature on CEs is replete with several dynamics, revealing their returns behaviour for diversification purposes, leaving very little to know about the returns behaviour of SE. Wherein, an avalanche of several initiatives on Corporate Social Responsibility (CSR) enjoin firms to operate socially responsible, but investors need to have a clear reason to remain sustainable into the foreseeable future period. Accordingly, the humble desire of investors is the formation of a well-diversified portfolio and would highly demand stocks to the extent that they form a reliable portfolio, especially, amid SEs and/or CEs.

本研究擬審查多頻率的及為市場成份的信息流和全球指數。

研究人員使用基於改良完全集合經驗模態分解自適應噪聲(Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise)的聚類分析法,取得Rényi有效轉移熵,藉此得到研究結果。

我們發現、於大部份多頻率,在持續性股票和傳統股票間有顯著的負信息流動,這會增加多樣化的益處。這些信息流大部份是雙向的,這強調了股票市場成份及其全球指數在構建投資組合上的重要性。

我們認為持續性股票市場和傳統股票市場大多為異質市場,這顯示了市場的低效率,而且這低效率的程度頗大。

關於傳統股票的實證性文獻裡是充滿了變革動力的,這顯示了它們以多樣化為目的的回報行為。這使我們對關於持續性股票的回報行為、認識變得實在太少了。於此,大量的企業社會責任的新措施不斷提醒各公司、要本著企業社會責任的理念去營運;但投資者需清晰明白他們為何需在可見的將來保持可持續性。因此,他們卑微的願望是一個較好的多樣化投資組合得以形成,故此他們高度要求股票要有組成可靠投資組合的性質和能力,特別是在持續性股票和/或傳統股票當中。

This study aims to investigate Malaysian stock market efficiency from the view of Sharīʿah-compliant and conventional stocks based on the effectiveness of technical trading strategies.

This study uses unconventional trading strategies that mix buy recommendations of Bursa Malaysia analysts with sell signals generated from 10 selected technical trading strategies (simple moving average, moving average envelopes, Bollinger Bands, momentum, commodity channel index, relative strength index, stochastic, Williams percentage range, moving average convergence divergence oscillator and shooting star) that are detected using ChartNexus. The period from 1 January 2013 until 31 December 2015 produces a total sample consisting of 1,265 buy recommendations of 125 Sharīʿah-compliant stocks and 400 buy recommendations of conventional stocks. The study period is extended until 31 March 2016 to provide an ample time for detecting the sell signal especially for buy recommendations that are released towards the end of 2015.

The resulting Jensen’s alpha show 8 out of 10 strategies are effective in generating abnormal returns in Sharīʿah-compliant samples while only 3 out of 10 strategies are effective in conventional samples. Prominent effectiveness of technical trading strategies in Sharīʿah-compliant stocks implies clear inefficiency in that stock market segment as opposed to those of the conventional stocks.

The results based on unconventional trading strategies provide new insights of Malaysian stock market efficiency especially in Sharīʿah-compliant and conventional stocks. The paper provides more robust findings on market efficiency as firms’ equity level data were focussed together with analysts’ buy recommendations from Bursa Malaysia.

The primary objective of this research is to chronicle how the Environmental Protection Agency (EPA) and other United States Federal Government Agencies (USFGA) agencies have played a role in shaping the trajectory of financial reporting for sustainability, with a particular emphasis on triple bottom line (TBL). This exploration extends to other indexes reporting sustainability data encompassed within financial, social and environmental reporting.

This study adopts an illustrative methodology, utilizing data sourced from governmental, business and international organizational documents.

Sustainability accounting predominantly finds its place within the framework of TBL. However, it is crucial to note that sustainability reporting remains voluntary rather than mandatory. Nevertheless, accounting firms and professional accounting societies have embraced it as a supplementary facet of financial accounting reporting.

The research highlights the historical evolution of sustainability within the USFGA and corporate entities. Corporations’ interest in accounting for sustainability performances has significantly contributed to the emergence of voluntary sustainability accounting rules, as embodied by the TBL.

The purpose of this paper is to show the relevance attributed to sustainability management control tools (SMCTs) and their real use. Mainly, this study aims to shed light on the approaches, motivations and difficulties encountered in SMCTs adoption by the most sustainable Italian companies, as well as their effectiveness.

Using a pre-structured qualitative survey method, the authors grasped information about external and internal dimensions of sustainability management in light of institutional and resource-based view theories. Data are elaborated with two methods: a regime analysis to assess the relevance of SMCTs and a descriptive analysis to investigate the “aim”, “which” and “how” of the SMCTs' use by companies listed in sustainability indices.

Informal SMCTs prevailed over formal ones. There is a discrepancy between attention paid to some tools praised in the literature and their knowledge and use. In addition, a significant gap exists between what is desired and what is achieved in terms of effectiveness. Further, although sustainability management is primarily oriented towards the external perspective, SMCTs can be key to improving both the disclosure and management of sustainability.

The criteria for the selection of the sample resulted in a small number of analysed companies, which allowed us to gain insight into what happens inside the listed Italian companies in the most important sustainability indices. These companies have sustainability-oriented management, which also probably safeguards their advantage linked to inclusion in these indices.

This paper provides food for thought for companies engaged in non-financial disclosure and for those who aim to implement SMCTs. It shows the need to reinforce formal sustainability control tools, also through dissemination of major knowledge about the implementation of these tools, and to encourage sponsorship from top levels of management.

Compared with SMCT research using a theoretical or case study approach, this study uniquely undertakes extensive research on the perceived effectiveness of SMCTs in achieving sustainability goals and the difficulties in implementing them, thereby highlighting a discrepancy between some tools emphasised in the literature and those infrequently used in sustainability-oriented companies.

As reaching UN Sustainable Development Goals 2030 has become the top agenda of the global companies, they have prioritized sustainability as a response to the grand challenges as well as a potential source of competitive advantage. This chapter poses the question: whether and how can firms achieve a sustainable competitive advantage via sustainability? I critically examine the sustainability-based view of sustainable competitive advantage by arguing that in the changing global landscape we will need to re-think the accepted ideas as regards sustainability goals, sustainable development and the sustainable competitive advantage as the individual firm’s achievement. The chapter contributes to the ongoing debate by discussing the potential of de-growth ideas and principles to solve some of the contradictions and suggesting the questions for future research.

This paper aims to verify whether the integration of sustainability in executive compensation positively affects firms’ non-financial performance and whether corporate governance characteristics enhance the relationship between sustainability compensation and firms’ non-financial performance and to expand the domain of the impact of sustainability on non-financial performance.

This analysis is based on a sample of companies listed on the Milan Italian Stock Exchange from the Financial Times Milan Stock Exchange Index over the 2016–2020 period. Regression analysis was used by using data retrieved from the Refinitiv Eikon database and the sample firms’ remuneration reports.

The findings of this paper show that embedding sustainability in executive compensation positively affects firms’ non-financial performance. The results of this paper also reveal that specific corporate governance features can improve the impact of sustainability on non-financial performance.

This analysis is limited to Italian firms included in the Financial Times Milan Stock Exchange Index; however, the findings are highly significant.

The findings provide regulators with useful insights for considering the integration of sustainability goals into executive remuneration. Another implication is that policymakers should require – at least – listed firms to fulfil specific corporate governance structural requirements. Finally, the findings can provide investors and financial analysts with a greater awareness of the role played by executive remuneration in the long-term value-creation process.

This paper contributes to addressing the relationship among sustainability, remuneration and non-financial disclosure, drawing on the stakeholder–agency theoretical framework and focusing on Italian firms. This issue has received limited attention with controversial results in the literature.

This paper aims to analyse the impact of the European Union (EU) Directive on the quality of sustainability reporting under the institutional theory lens. Specifically, the authors evaluate what kind of institutional pressure has the highest impact on the quality of corporate disclosure on sustainability issues.

The authors build a quality index based on the content analysis of sustainability information disclosed, before and after the transposition of the Directive, by Italian and Spanish companies belonging to different industries. The authors use an OLS regression model to analyse the effect of coercive, normative and mimetic forces on the quality of the sustainability reports.

The results highlight that normative and mimetic mechanisms positively affect the quality of sustainability reporting, whereas there is no evidence regarding coercive mechanisms, indicating that the new requirements do not provide a significant contribution to the development of better reporting practices, at least in the two analysed countries.

To the best of the authors’ knowledge, this is one of the few studies assessing the quality of sustainability reporting through an analysis involving the period before and after the implementation of the EU Directive. It enriches the literature on institutional theory by analysing how the different dimensions of isomorphism affect the quality of information disclosed by companies according to the EU requirements. It contributes to a better understanding of the impact of the non-financial information Directive, and the results of this paper can be relevant for regulators, practitioners and academia, especially in view of the adoption of the new Corporate Sustainability Reporting Directive proposal.

The purpose of this paper is to investigate current practices of water governance disclosure in the food, beverage and tobacco industry and to determine whether the quality of disclosure has a positive association with integrated reporting (IR).

A water governance disclosure index was developed that used content analysis to code the latest standalone social, environmental and sustainability reports or integrated reports of 49 companies in the food, beverage and tobacco industry. The selected companies are listed on three indices, the ASX, JSE and DJSI. This was followed by quantitatively testing the association between IR and the quality of water governance disclosure, as measured against the qualitatively developed index.

It was found that the 18 IR companies’ water governance disclosure quality significantly outperformed the 31 companies in the non-IR group, with a calculated index score of 71.67% and 40.97%, respectively.

The evidence indicates that IR is superior to non-IR water governance disclosure, and the study, therefore, contributes to the literature around the legitimacy theory by concluding that IR is supportive to companies to legitimise their being.

The originality of this paper stems from the comparison of water governance disclosures between IR and non-IR firms. Considering that IR preparers outperformed companies in the non-IR group could provide insights to academics, regulators and reporting organisations that IR could be used to enhance water governance disclosure.

This paper aims to examine the extent of price clustering in a selection of Islamic stocks listed in Indonesia, Malaysia and Pakistan and also investigates the determinants of the phenomenon at the firm level.

The author test the uniformity of price distribution in the selected securities. Then, the determinants of price clustering were investigated through multivariate analysis based on a binary logistic regression model. Following the arguments of Narayan et al. (2011), who emphasize the importance of considering firm heterogeneity when studying the phenomenon, the author conducts the empirical study at the firm level.

The evidence indicates that Islamic stocks show a mild level of price clustering. Only half of the stocks under analysis rejected the uniformity test in the distribution of prices. In these cases, investors exhibited a preference for prices ending at zero and five. The evidence does not confirm the cultural clustering theories. Price clustering is found to be positively associated with price level and relative bid-ask spread. Overall, the negotiation hypothesis, which predicts that investors prefer round prices to minimize the costs associated with negotiations, best explains most of our results.

The existence of price clustering is difficult to reconcile with the prediction of the efficient market hypothesis that prices should follow a random walk. Moreover, the evidence indicates that Muslim investors share a preference for round prices in some settings, under the assumption that Islamic stocks are mostly traded by Muslim investors.

To the author’s best knowledge, this is the first study to address the subject of price clustering in Islamic stocks.

This study examines the internationalization effects of corporate social responsibility (CSR) reporting, specifically aiming to identify and compare the CSR reporting practices of large US multi-national corporations (MNCs) and their Polish subsidiaries.

Based on content analysis and using a disclosure index, the authors examined the CSR information posted on, or linked to, the corporate websites of a sample of 60 US-based MNCs and their subsidiaries operating in Poland.

The findings indicate that US companies, despite operating in a less regulated environment, had more extensive disclosure than their Polish subsidiaries and covered more CSR-related topics. CSR disclosures within the US subsample were analogous in volume and detail. By contrast, only about half of Polish companies provided CSR disclosures, which were more diverse in volume and in the types of activities disclosed. The authors did not find a significant positive correlation between the CSR disclosures of the two subsamples.

The study contributes to the literature on internationalization processes and sustainability practices. It provides insights into the CSR reporting of companies located in Central and Eastern European countries. The findings also have implications for policymakers in incentivizing the enhancement of the reporting disclosure practices of companies.
