In response, Chinese listed enterprises are showing that they are willing to embrace social responsibility and maintain environmental reputation by actively taking part in the Carbon Disclosure Project (CDP). The motivation behind and efficacy of these disclosures, however, remain unclear due to the inherent challenge of integrating environmentally beneficial activities into the supply base. Accordingly, this study examines the relationship between upstream supply chain and climate change disclosure levels of enterprises through the lens of dynamic operational capability. Using an ordinal logistic regression analysis of 1092 climate change disclosures of Chinese listed enterprises, we find that enterprises with high supplier concentration have higher levels of climate change disclosure. This impact is further amplified in firms with higher levels of lean production and high absorptive capacity, yet attenuated in firms that prefer to use a differentiation strategy. In addition, this study further utilises climate change disclosure rating as a mediating effect to explore its effectiveness on enterprises' profitability. Overall, this study reveals the significance of supplier concentration and key dynamic operational capabilities to climate change disclosure, contributing to the stream of environmental disclosure in suppliers' cooperation.</p>\u0000 </div>","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":"31 1","pages":"1024-1043"},"PeriodicalIF":2.8,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146007591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article proposes a theoretical framework to explain the dynamics of the public debt-to-GDP ratio over the business cycle by categorising them into three phases. There is a bounded interval within which the public debt-to-GDP ratio is in the counter-cyclical phase, increasing in booms and decreasing in recessions. The debt-to-GDP ratio is in the accumulation phase when it is below the interval and in the reduction phase when it is above the interval. Importantly, the accumulation or reduction phase is expected to be followed by the counter-cyclical phase. The bounded interval is not static, implying the significant recurrence of the counter-cyclical phase and the time-varying cyclical properties of the debt-to-GDP ratio. This study further proposes an iteration scheme to estimate the interval. Empirical results from five developed and five developing countries indicate that the patterns of the three phases differ across countries but exhibit similar trends within each country group. External factors such as income risks and austerity can change the bounds of the interval, thereby shifting the public debt dynamics to the accumulation or reduction from the counter-cyclical phase.</p>\u0000 </div>","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":"31 1","pages":"1005-1023"},"PeriodicalIF":2.8,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146007592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results indicate that second-generation involvement can decrease earnings management, particularly regarding real earnings management. This suggests that second-generation managers have incentives to protect the family's reputation and prioritise long-term benefits, thus avoiding the negative consequences of real earnings management on socioemotional wealth. The heterogeneity analysis shows that the curbing effect on real earnings management is stronger when second-generation members have longer tenure, higher education levels, overseas backgrounds, and are female, older, or in key positions.

Nevertheless, despite the increasing level of interest in corporate donations among managers, academics, and the business community, literature on how and whether corporate donations impact earnings management is still scarce. As a result, this study aims to examine the relationship between corporate charitable donations and earnings management (EM) practices, considering the interacting role of boardroom gender diversity. Based on stakeholder theory, we posit that donating firms behave ethically to meet shareholders' needs and society expectations, thereby eliminating the opportunistic perspective of earnings management. Furthermore, the presence of female directors' acts as a signal for financial reporting quality and mitigates the agent-principal conflicts of interests. By using a fixed effect regression on panel data of 79 Turkish-listed firms from 2008 to 2022, the results show that corporate donations are positively associated with discretionary accruals, suggesting that donating firms are more likely to engage in earnings management. The results also show that gender diversity on boards helps greatly in mitigating the positive link between corporate donations and income-increasing abnormal accruals. Our findings have important implications for investors when assessing donating firms since such donations may be used as a strategy mechanism to window-dress their reputation. This article advances our understanding of the interplay among corporate donations, board gender diversity, and earnings management in an emerging market.</p>\u0000 </div>","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":"31 1","pages":"1472-1486"},"PeriodicalIF":2.8,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146001994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We fill this gap by using data from 2012 to 2022 of Chinese listed manufacturing companies in the Shanghai Stock Exchange and Shenzhen Stock Exchange to examine the impact of corporate ESG performance on export intensity and the role of ownership structure in this link. Results indicate that enhanced ESG performance is positively related to export intensity. Such an effect is weakened for state-owned enterprises. We further propose that the potential mechanisms include alleviating financing constraints, promoting innovation, mitigating principal–agent problems and elevating reputation levels. The ownership structure significantly moderates the positive impact of ESG performance on export intensity. We suggest that small-scale enterprises are more prone to be influenced by the positive effect of ESG performance on export intensity than larger ones. Moreover, among the ESG subdimensions, the environmental and governance dimensions play more significant roles in enhancing export intensity than the social dimension. The findings shed light on how to reap ESG benefits for export-oriented manufacturing enterprises and promote their export intensity for firms' stakeholders and policymakers, thus providing practical policy recommendations.</p>\u0000 </div>","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":"31 1","pages":"789-803"},"PeriodicalIF":2.8,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146001984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In terms of parameter estimation, we develop a quasi-maximum likelihood estimation method and establish its asymptotic properties. Building on this, we propose three hypothesis testing statistics to determine whether the data exhibits a noncausal AR structure and whether the innovation term follows a noncausal ARCH model.
