This study assesses the potential impact of financial reporting practices, specifically accounting conservatism, on a firm’s CSP activities, which has significant implications for diverse stakeholders. Employing an accrual-based proxy for accounting conservatism and the social contribution value per share from the Shanghai Stock Exchange as a proxy for CSP, the study utilizes a sample of 25,490 year-company observations of A-share listed companies on China’s Shanghai and Shenzhen stock exchanges spanning from 2008 to 2019. Empirical findings indicate a negative correlation between accounting conservatism and CSP. The study suggests that higher levels of social performance are associated with reduced conservatism in financial reporting, indicating that firms prioritize CSP over the interests of financial stakeholders by adopting less conservative financial reporting policies. Aligned with agency theory, these results underscore that socially responsible firms are less inclined to employ accounting conservatism in reporting earnings. This study establishes a connection between firms’ unconventional and less traditional activities, such as CSP, and conservative financial reporting, offering valuable insights for investors, analysts, and regulators.\u0000AcknowledgmentThis paper is co-funded by the European Union through the European Education and Culture Executive Agency (EACEA) within the project “Embracing EU corporate social responsibility: challenges and opportunities of business-society bonds transformation in Ukraine” – 101094100 – EECORE – ERASMUS-JMO-2022-HEI-TCH-RSCH-UA-IBA / ERASMUS-JMO-2022-HEI-TCHRSCH https://eecore.snau.edu.ua/","PeriodicalId":39060,"journal":{"name":"Investment Management and Financial Innovations","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138962782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article traces the research gap in addressing food insecurity by focusing on the role of food retail chains in the former “Eastern Bloc” in light of unprecedented food price inflation and the resulting scale of demand for the services of food banks. Through empirical analysis of secondary financial corporate data, a low level of their profitability in the period of 2011–2019 was revealed, which preceded the synchronicity of two unexpected global economic downturns. Specifically, Return on Sales for food retailers located in the Czech Republic and Hungary was generally below 2%, offset by higher Total Asset Turnover figures, consistent with the need to extend the volume of goods for sale. Development in profitability in selected newer EU member states is just as significantly similar to the situation in Ukraine. The mutual interaction of factors of economic size and the country of residence of business was analyzed regarding a possible influence on their financial performance. This study concluded that the presence of unresolved market distortions can both lead to increased food insecurity and, paradoxically, contribute to increased food waste.\u0000AcknowledgmentThe authors are thankful to the Internal Grant Agency of Mendel University in Brno for financial support to carry out this research as the partial output of the project No. IGA-PEF-TP-23-015 “Zajišťování výživových potřeb obyvatelstva vzhledem k aktuálním výzvám v oblasti regenerativních přístupů při vykonávání hospodářských činností podniků agropotravinářského komplexu se zaměřením na roli tuzemských potravinových bank”.","PeriodicalId":39060,"journal":{"name":"Investment Management and Financial Innovations","volume":"272 35‐38","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138997260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the bullish rally of 2022 persists, Indian stock markets remain enticing for foreign institutional investors in 2023. A resurgence in IPO activity is anticipated, driven by increasing momentum and larger deals that are poised to overcome the constraints of subdued global sentiments and liquidity pressures, addressing the challenges posed by these factors. The study offers insights into factors influencing IPO subscriptions, capitalizing on the context of heightened stock market volatility and optimistic trends in the Indian stock market. A total of 132 IPOs listed on the Indian stock market between April 2019 and March 2023 were analyzed in this study. Multiple Linear Regression was used to assess the strength of the association between several factors outlined in the literature, and the overall subscription. Among the ten variables investigated in the study, it was observed that three variables under the external factors, specifically Grey Market Premium, IPO Rating, and Broker Recommendations, exerted a significant influence on the overall subscription. While other factors such as allocation proportion and issue attributes, were found to have no discernible influence on the overall subscription. The results indicate that the Indian IPO market demonstrates a prevalence of speculative behavior and a stronger reliance on expert recommendations, rather than being primarily driven by IPO characteristics.\u0000Acknowledgment Authors acknowledge that the publication fee is funded by Kingdom University, Bahrain.","PeriodicalId":39060,"journal":{"name":"Investment Management and Financial Innovations","volume":"14 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139004854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research method uses a quantitative approach with statistical tools and hypothesis testing. Regression analysis through path analysis models is used to test the proposed hypothesis. The results showed asset growth of 15.42%, debt-equity ratio of 1.7797, and high Price to Book Value (36.2721). Nonetheless, leverage does not act as a mediator in the relationship between asset growth and company value, defying the Modigliani-Miller theory. The finding highlights the complexity of such factors in the context of LQ-45 companies, emphasizing the need for prudent asset management and debt policy to enhance competitiveness.

This results in prompt investment decisions regarding the company. Consequently, earnings information will be immediately reflected in stock prices, thereby reducing stock price drift. The purpose of this study is to examine the impact of investments in establishing and operating internal accounting systems on investors’ responses to the mitigation of stock price drift. The study focused on firms listed on the Korea Exchange from 2011 to 2018 and constructed a regression model using the cumulative abnormal return following earnings disclosure dates for 30, 60, and 120 days as the dependent variable, with the characteristics of internal accounting personnel as independent variables. The analysis reveals that companies with many internal accounting personnel and position experts, such as accountants, within their internal accounting control systems, experience a significantly lower stock price drift. The coefficients of the interaction terms between internal accounting personnel characteristics and standardized unexpected earnings are positive and significant at the 1% level for all cumulative abnormal return values. The findings of the study indicate that as efficiency is secured, stemming from the scale of personnel managing internal accounting control systems and their expertise, market investors’ understanding and trust of accounting information also increase. Investors, as information users, react promptly to the earnings information disclosed by the company, leading to a decrease in stock price drift.\u0000AcknowledgmentsThis work was supported by the Ministry of Education of the Republic of Korea and the National Research Foundation of Korea (NRF-2021S1A5A8070518).","PeriodicalId":39060,"journal":{"name":"Investment Management and Financial Innovations","volume":"26 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138593664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the implementation of climate change initiatives has prompted companies to disclose information regarding their evaluation and handling of climate-related risks and potential benefits. However, there is a lack of existing literature that investigates this issue in less developed markets, particularly in Saudi Arabia, where the capital market is rapidly developing. The objective of this study is to assess the degree of performance in reporting climate risk and investigate potential correlations between climate risk reporting performance and firm characteristics among non-financial firms in Saudi Arabia during the period from 2018 to 2021. To achieve the objectives of the study, a total of 515 firm-year observations were utilized, representing 140 non-financial firms in the context of Saudi Arabia. The study’s findings illustrate that the climate risk reporting performance level has steadily improved in Saudi companies over the years. In addition, the findings reveal that firm size and industry exhibit a positive correlation with climate risk reporting performance. Conversely, firm leverage and profitability do not demonstrate such associations. The results are in line with alternative measures of climate risk reporting performance, as well as when climate risk reporting performance is broken down into the four core elements. Policymakers and market regulators could use these results to promote awareness of the factors that influence climate risk reporting performance and to enhance sustainable practices.","PeriodicalId":39060,"journal":{"name":"Investment Management and Financial Innovations","volume":"108 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138590753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current necessity is to determine the level of consequences for distinct industries and sectors. The local lockdowns and travel restrictions shocked the hospitality industry and its performance. Thus, the purpose of this study is to explain the effect of the pandemic on a particular economic sector, specifically NACE I (Accommodation and food service activities), and changes in financial indicators in Slovak circumstances for the period 2016–2021. The study focuses on debt ratios that reflect the financial stability of businesses. Friedman’s test was run to determine how the chosen indebtedness indicators developed over the chosen years. Based on a sample of 321 Slovak companies, statistically significant differences were found. But only the interest coverage ratio was significantly different between the pre-pandemic and pandemic eras, according to the post-hoc tests. In addition, there was a hint of a positive overall transformation in the sector of accommodation and food service activities. The decline of the number of enterprises by total indebtedness from the alarming threshold in 2021 declared this fact. The conclusions implicate that Slovak businesses are becoming more mindful of debt financing and are attempting to reduce the risks of going bankrupt.\u0000AcknowledgmentThis research was financially supported by the Slovak Research and Development Agency – Grant Vega 1/0121/20: Research of transfer pricing system as a tool to measure the performance of national and multinational companies in the context of earnings management in conditions of the Slovak Republic and V4 countries and faculty institutional research 1/KE/2022: Analysis of the determinants of indebtedness and profitability of business entities in the European area.","PeriodicalId":39060,"journal":{"name":"Investment Management and Financial Innovations","volume":"35 38","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138601325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To estimate accrual-based earnings management practices, the modified Dechow and Dichev (2002) model was mobilized. Then, a regression between earnings management estimated values based on accruals and a group of capital structure variables and control variables that are hypothesized to influence earnings management practices is performed. The feasible generalized least square model is used to address econometric issues. Empirical results reveal that activities for managing accrual-based earnings indicate a considerable adverse influence from institutional ownership. However, other hypothesized variables that are management ownership, ownership concentration, foreign ownership, and leverage do not have a determinant sign as expected. ROA, one of five control factors, has a favorable impact on accrual-based earnings management practices, whereas company size has a negative impact. The study provides useful information to investors and stakeholders for their making investment decisions in Vietnam. The empirical findings are also based for recommendations to control earnings management practices at Vietnamese listed enterprises to enhance accounting information quality, thus contributing to the sustainable development of the Vietnam Stock Exchange.","PeriodicalId":39060,"journal":{"name":"Investment Management and Financial Innovations","volume":"119 18","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135138487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
