They also equip researchers with powerful tools to study important but subtle/challenging topics that are impossible to explore before on a large scale, such as corporate culture and climate risk exposure. In this review, I survey various applications of different machine learning techniques in ESG research, beginning with foundational methods such as bag-of-words, progressing through topic modeling, word embedding, and BERT, and culminating with generative artificial intelligence (AI) and other advanced machine learning approaches. I conclude by outlining future directions for using big data and machine learning in ESG research.</p>","PeriodicalId":8570,"journal":{"name":"Asia-Pacific Journal of Financial Studies","volume":"54 1","pages":"6-21"},"PeriodicalIF":1.8,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the consequences of a co-CEO structure have been relatively underexplored in prior research, existing studies suggest potential benefits, such as higher valuations and stronger internal governance. This paper delves into the specific consequences of a co-CEO structure, focusing on earnings smoothing practices. Using data from Korean firms, where co-CEO structures are prevalent, we find that firms with a co-CEO structure exhibit smoother earnings compared to those with a sole-CEO structure. However, the informativeness of these smooth earnings is reduced under a co-CEO structure, suggesting that co-CEOs engage in earnings smoothing primarily for their own benefit, rather than to provide more information to investors. Additional analyses reveal that co-CEOs' earnings smoothing leads to adverse consequences for investors, including lower earnings quality, higher costs of capital, increased financial distress, greater credit risk, and higher stock price crash risk. Our study contributes to the literature by highlighting the potential costs associated with co-CEO structures, particularly in terms of reduced earnings informativeness.</p>","PeriodicalId":8570,"journal":{"name":"Asia-Pacific Journal of Financial Studies","volume":"54 1","pages":"82-109"},"PeriodicalIF":1.8,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we test whether corporate site visits can improve ESG ratings using a unique dataset of site visits from Chinese listed firms. We find that corporate site visits can lead to improved ESG performance for listed firms, which is robust even after adding a series of control variables, alternative model specifications, and accounting for endogeneity issues. This effect is attributed to the mediating effects of ESG information disclosure and corporate internal control quality. We also find that the more ESG-related discussion during site visits the better managers learn to improve ESG performance of their firms. Furthermore, there is evidence that the positive effect of site visits on ESG are more pronounced among firms that are not audited by Big Four accounting firms, not cross-listed, and when Qualified Foreign Institutional Investors are involved. Overall, this paper contributes to the literature by providing complementary evidence that site visits are an important platform for communicating between investors and corporate management, which can have profound implications on incentivizing managers to deliver better ESG performance. Our findings also offer practical and policy implications to regulators on the promotion and implementation of ESG in listed firms.</p>","PeriodicalId":8570,"journal":{"name":"Asia-Pacific Journal of Financial Studies","volume":"54 1","pages":"22-53"},"PeriodicalIF":1.8,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This negative effect is mitigated when analysts are less concerned about their disadvantages in the new intrafirm tournament—specifically, when they are more experienced, more competent, or have moved to more prosperous brokerage houses.
