Purpose: In recent years firms tend to direct their attention in communicating their environmental actions with their stakeholders. However the level of environmental disclosers varies significantly among firms. This paper aims to explain the variation in environmental disclosure of firms based on their ownership type namely – state ownership and institutional ownership. The study further aims to understand whether and how the relationship between ownership structure and environmental disclosure changes regarding countries’ development levels. Design/methodology/approach: This paper uses a sample of 27847 firm-year observations from 72 countries/economic districts between the years 2002 and 2017 and regression analysis to test how the relationship between different ownership structures and environmental disclosure and whether this relation is conditional on countries’ development levels. Findings: This study finds that firms with higher state ownership have higher environmental disclosures and higher institutional ownership has a negative effect on environmental disclosures. Furthermore this paper also documents that firms with higher state ownership and operating in developed countries have incrementally higher environmental disclosure relative to firms operating in developing countries. Research limitations/implications: The study has limitations that would provide possible starting points for further research. The first limitation is related to the environmental disclosure measure which reflects the level of environmental disclosure of firms based on their disclosure information given in the Thomson Reuters Asset4 database. A more refined measure can be constructed using hand-collected data based on linguistic analysis which may reflect not only the level of the disclosure but also the quality of the environmental disclosure. The second limitation is the limited focus of the study toward state and institutional shareholding. Therefore future research may consider examining the different types of ownership such as family ownership. Practical implications: The findings of the study may help policymakers and regulators to consider the potential impact of various ownership types on environmental disclosures. Also given the impact of countries’ development levels regulators should consider that a one-size-fits-all is not applicable in environmental disclosures. Therefore each country should consider the institutional dynamics of their operating environment to set appropriate regulations to enhance environmental disclosures. Social implications: From a social perspective the findings indicate that firms’ stakeholder engagement via environmental disclosures depends on the type of the controlling shareholders. Originality/value: This study contributes to the literature by developing a new construct for environmental disclosure based on Biodiversity Climate Change Environmental Investments and Spill Impact Reduction performance measures. Further grounding on legitimacy and stakeholder theories this study shows the influence of ownership type on environmental disclosures and how this effect changes in accordance with the countries’ development. © 2021 Elsevier B.V.

From Conventional Methods to Contemporary Neural Network Approaches: Financial Fraud Detection
(Springer Nature, 2021) Mustafa Reha Okur; Yasemin Zengin Karaibrahimoglu; Dilvin Taşkın; Zengin-Karaibrahimoglu, Yasemin; Taşkın, Dilvin; Okur, Mustafa Reha
This chapter provides insights on the underlying reasons to replace the conventional methods with contemporary approaches—the neural network-based machine learning methods—in financial fraud detection. To do this we perform a systematic literature review on the evolution of financial fraud detection literature over the years from traditional techniques toward more advanced approaches such as modern machine learning methods like artificial neural networks. Additionally this chapter provides concise chronological progress of the fraud literature and country-specific fraud-related regulations to draw a better framework and give the idea behind the corpus. Using the metadata in the existing literature we show both benefits and costs of using machine learning-based methods in financial fraud detection. An accurate prediction using contemporary approaches is essential to minimize the potential costs of fraudulent financial activities for stakeholders reduce the adverse effects of fraudsters’ and companies’ fraudulent activities and increase trust in capital markets via continuous fraud risk assessment of companies. © 2021 Elsevier B.V.

Ownership and corporate social responsibility: The power of the female touch
(ELSEVIER SCI LTD, 2021) Duygu Seckin-Halac; Ece Erdener-Acar; Yasemin Zengin-Karaibrahimoglu; Zengin-Karaibrahimoglu, Yasemin; Erdener-Acar, Ece; Seckin-Halac, Duygu
Using a sample of 26029 firm-year observations over the period 2002-2017 from 4479 firms and 44 countries we examine the relationship between ownership concentration and corporate social responsibility by focusing on the mediating role of board gender diversity and the moderating role of family shareholding. We find that ownership concentration negatively affects corporate social responsibility and the board gender diversity partially mediates this negative effect. Our results indicate that the mediating effect of board gender diversity leads to a 10.65 percent decrease in the impact of ownership concentration on corporate social responsibility. Furthermore moderated path analysis indicates that family shareholding weakens the direct effect of ownership concentration on board gender diversity and its indirect effect on corporate social responsibility. In post hoc analysis we also document that the effect of gender diversity on the board is more prevalent in high gender-egalitarian societies where women are more involved in decision-making. Our study addresses the strategic role of female board members in increasing firms' respect for corporate social responsibility especially in family controlled firms. Thus our results may provide insights to regulators and policymakers to enhance firms' corporate social practices by encouraging women's participation on corporate boards. (c) 2021 Elsevier Ltd.
