The second objective is to analyze OPU's moderating impact on dynamic conditional correlations (DCCs) and asymmetric dynamic conditional correlations (ADCCs) between EU-ETS returns and European equity market returns. To extract DCCs and ADCCs between carbon and stock returns, we employ the DCC-EGARCH and ADCC-EGARCH approaches with a range of robustness diagnostics. Thirdly, we utilize the hedge ratio and optimal portfolio weight selection approaches, guided by the DCC-GARCH-t copula method, to examine the hedging effectiveness (HE) against long-term OPU shocks through short-term positioning in European financial market returns and EU-ETS returns. Overall findings reveal asymmetric spillovers in extreme conditions, negatively affecting Belgian and Spanish firms in the long term due to EU-ETS-induced price increases. Long-term investors are advised to consider reallocating investment funds to the stock markets that are favorably impacted by EU-ETS fluctuations (Finland, France, Germany, Ireland, Italy, and the Netherlands) to achieve optimal gains during bullish equity market trends. However, simultaneous short-term negative OPU effects are observed in all economies' stock markets at all quantiles. The results also underscore OPU's moderating impact on stock‑carbon conditional connectedness, emphasizing the need for fund managers to acknowledge OPU as a moderating risk factor for carbon-stock hedging effectiveness.</div></div>","PeriodicalId":48226,"journal":{"name":"International Review of Financial Analysis","volume":"104 ","pages":"Article 104324"},"PeriodicalIF":7.5,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using survey data from a sample of French investors, we primarily find no significant gender differences in the proportion of ESG funds or stocks held, nor in the <em>willingness to pay</em> to invest in a firm with a high ESG score. However, this lack of significance results from two simultaneous significant indirect gender effects acting in opposite directions. On the one hand, women, compared to men, are found to more strongly endorse specific sustainability criteria related to the fight against discrimination, which, in turn, increases the adoption of socially responsible investing behavior. On the other hand, women's weaker interest in great global environmental challenges results in a decrease in their ESG exposure. These attitudinal differences by men and women align with findings in social psychology literature, which suggests that women's adoption of pro-social/environmental behaviors is typically motivated by <em>communal</em> attitudes (i.e. community-oriented), whereas for men, such behaviors are more often driven by <em>agentic</em> motivations (self-rewarding).

We find that the decision to freeze SERPs is predominantly influenced by the power dynamics between top executives and the board of directors, alongside talent retention concerns. Moreover, our analysis reveals that SERP freezes lead to significant changes in corporate behavior. Firms that implement these freezes tend to distribute pension-related cost savings to their shareholders and are less likely to pursue diversification strategies than firms that keep their SERPs open. This risk-shifting behavior manifests in lower equity and higher credit risk post-freeze.

Based on the research scenario in which data-trading platforms have been successively established in various cities in China since 2014, this study constructs a multiperiod difference-in-differences model to explore the impact and mechanism of data element marketization on corporate investment efficiency. Results indicate that data element marketization can significantly enhance corporate investment efficiency, with mechanism analysis revealing that this effect occurs by intensifying market competition, alleviating financing constraints, and improving management efficiency. Heterogeneity analysis reveals that data element marketization has a more pronounced effect on investment efficiency in samples with better corporate governance, higher corporate technological intensity, better regional legal institutional environments, and greater local government attention to the digital economy.

We examine the impact of firms' ESG disclosures on analyst earnings forecast accuracy (AEFA) using a nonlinear approach to capture both sides of ESG effects. Our nonlinear findings suggest that ESG disclosure has a U-shaped effect on AEFA. Specifically, a firm's ESG disclosure enhances AEFA but at a decreasing rate. The favorable effect becomes smaller as firms disclose more ESG, and eventually, increases in ESG disclosure led to worsening AEFA. The conclusion remains unchanged after an array of robustness checks. The mechanism test reveals that earnings management and media attention mediate the U-shaped relation between ESG disclosure and AEFA. Additional analysis shows that the U-shaped relation is more salient for SOEs and non-polluting firms. The findings not only broaden the research on the impact of ESG disclosure on AEFA, but also help investors make sound investment decisions.</div></div>","PeriodicalId":48226,"journal":{"name":"International Review of Financial Analysis","volume":"104 ","pages":"Article 104332"},"PeriodicalIF":7.5,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
