{"title":"Is earnings management impacted by audit fees and auditor tenure? An analysis of the Big Four audit firms in the US market","authors":"José Manuel Santos-Jaén, Gema Martín de Almagro-Vázquez, María del Carmen Valls Martínez","doi":"10.24136/oc.2023.027","DOIUrl":"https://doi.org/10.24136/oc.2023.027","url":null,"abstract":"Research background: Audits are intended to ensure the reliability of financial statements, as this is fundamental for different stakeholders. However, both auditor tenure and audit fees could affect the earnings management of companies. In 2014, the European Union established a mandatory audit firm rotation policy. In the United States, although there is still no mandatory regulation in this regard, there has been a large public debate over the advisability of this policy. Another unresolved controversy is whether audit fees determine audit quality. Purpose of the article: The aim of this research is to study the effect of auditor tenure and audit fees on earnings management, i.e., to determine whether a longer-term relationship between the auditor and the audited company, as well as higher audit fees, reduce the audited company's earnings management, thereby making the financial statements more reliable for stakeholders and increasing the quality of the audit report. In addition, the Big Four auditing companies in the United States were analyzed in order to determine the influence of corporate culture. Methods: A sample of companies listed in the S&P 500 stock market index was employed for the analysis, covering the years 2012 to 2021, resulting in a dataset comprising 3,010 observations. To examine the research hypotheses while mitigating the potential bias from omitted variables, a linear regression analysis was conducted using panel data with fixed effects regression. To enhance the robustness of the results, winsorized variables were also employed. Findings & value added: Overall, the results confirm that the quality of financial statements improves as auditor tenure increases, and so implementing a mandatory auditor rotation may not be in a company’s best interests. The results also support the market segmentation theory, as higher audit fees are aligned with higher quality financial reporting. Furthermore, by analyzing the Big Four audit companies in the US, it is shown that the influence of audit fees and auditor tenure on earnings management also depends on the internal aspects of the particular audit firm, especially its ethical culture. In sum, US policymakers should neither set limits on audit fees nor enforce a mandatory audit firm rotation similar to that of the EU.","PeriodicalId":46112,"journal":{"name":"Oeconomia Copernicana","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136158356","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}

Purpose of the paper: The main goal of the presented study was to test the ESI prediction capabilities and its components in a relation to the economic cycles of the EU countries in the individual time periods. Methods: The time series for the period Q1 2000 to Q4 2022 and the three selected time periods were a subject to undergo the selection of the cyclical component applying the Hodrick-Prescott filter and then, the relationship between the variables was determined employing the Pearson correlation coefficient with the time shifts. The relation of ESI and its components to GDP and the Index of Industrial Production (IIP), which represent the economic cycle, was analysed. The prediction volume and the cross-correlation values determined the nature of the observed cyclical variables. Findings & value added: The results of the analysis point to the fact that ESI and its components are able to ensure a high-quality prediction of the economic cycle only in the selected EU countries. Regarding the components of the ESI, the Consumer confidence indicator, Construction and Industrial confidence indicators show the best predictive capabilities. The analytical outcomes show that the ESI size and lead period vary over time and after the 2008 crisis, the ESI showed better predictive capabilities in a relation to GDP and IIP than before the crisis. The Covid 19 pandemic had a significant negative impact on the ESI predictive capabilities.","PeriodicalId":46112,"journal":{"name":"Oeconomia Copernicana","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135082627","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}

{"title":"Circular economy practices as a tool for sustainable development in the context of renewable energy: What are the opportunities for the EU?","authors":"Ugnius Jakubelskas, Viktorija Skvarciany","doi":"10.24136/oc.2023.025","DOIUrl":"https://doi.org/10.24136/oc.2023.025","url":null,"abstract":"Research background: In order to tackle climate change and ensure Paris agreements are met, countries are forced to look for alternative ways of producing, consuming, and wasting and adopt a circular economy. Reduction of greenhouse gas emissions becomes one of the key elements. The demand for electricity is increasing, and most greenhouse gas emissions derive from the energy sector. Because of that, it is crucial to ensure the transition from fossil fuels to renewable energy. Renewable energy, as a part of the circular economy, also contributes to sustainable development. Only the efficient implementation of circular economy and renewable energy practices can ensure that sustainable development goals are achieved. Purpose of the article: The study aims at determining the efficiency of European Union countries implementing circular economy practices through renewable energy to attain SDGs. The study focuses on the significance of renewable energy as a tool for the circular economy to achieve sustainable development and highlights the progress achieved in SDG through renewable energy in the EU. Methods: For efficiency assessment of the circular economy represented by the renewable energy indicators, data envelopment analysis (DEA) was performed. Findings & value added: This study presents a relation analysis of the circular economy and renewable energy and the importance of efficiency in achieving SDGs through a circular economy. The study helps to understand the circular economy represented by renewable energy and how it transforms into sustainable development and contributes to necessary actions needed for countries to improve. Based on the results, Sweden, Luxembourg, Ireland, Latvia, Estonia, Malta, the Netherlands and Bulgaria are considered the most efficient countries, while Austria is the least efficient. Unused solar and wind power potential can slow down sustainable development; however, EU programs and renewable energy strategies help countries move towards clean energy and ensure efficient implementation of sustainable development goals.","PeriodicalId":46112,"journal":{"name":"Oeconomia Copernicana","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135082621","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}

Purpose of the article: The purpose of the article is to investigate the impact of rule of law, corruption, and terrorism on tourism in 14 coastal states of the Mediterranean Sea based on the United Nations classification. Methods: The short and long-run relationships among the rule of law, corruption, terrorism and tourism are respectively analyzed through Dumitrescu and Hurlin causality test and LM bootstrap cointegration test taking notice of the presence of heterogeneity and cross-sectional dependence. Findings & value added: The causality analysis reveals that control of corruption has a significant influence on tourism only in the short run. The cointegration analysis uncovers that terrorism negatively affects the tourism in Albania, Algeria, Egypt, and Tunisia, but improvements in corruption also positively affect the tourism in Albania, Algeria, Bosnia and Herzegovina, Greece and Italy. Last, the rule of law has a positive impact on tourism in Egypt, Greece, and Israel. In this context, the rule of law can also be a key factor for tourism development via combat with corruption and terrorism. Based on some unique characteristics, the Mediterranean region has consolidated its position as the world's leading tourist destination, but to maintain this competitive position, it is crucial to recognize and adopt strategies that respond to all key challenges faced by this sector.","PeriodicalId":46112,"journal":{"name":"Oeconomia Copernicana","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135083034","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}

Solar adoption surged in Bangladesh up until 2015, setting a global precedent for electrifying areas that were previously unconnected. The enhanced lighting offered by solar systems provides immediate benefits, including additional hours for household and business activities and extended study hours for school-going children. Purpose of the article: This study seeks to identify the determinants and welfare gains of solar adoption in rural areas by analysing three rounds of the Bangladesh Integrated Household Survey from 2011–12, 2015, and 2018–19. In addition to presenting new estimates of economic, environmental, and educational welfare gains, our research offers insights into how solar adoption relates to rural employment and the nutrition of children under five. Methods: We utilized both ordinary least squares and propensity score matching techniques to estimate the welfare effects of solar adoption. Only households that do not use electricity as their primary lighting source, such as those relying on solar or kerosene, are considered in our sample. Findings & value added: We have discovered that adopting solar is linked to higher income, increased expenditure, and growth in asset value. Additionally, there is a significant reduction in kerosene expenditure among adopters compared to non-adopters. Other observations reveal that households with solar setups tend to transition from sharecropping to trading and poultry farming. Children in these households also benefit from solar adoption in terms of education and nutrition. This study illustrates how solar energy can effectively address various welfare concerns in areas where the government cannot supply electricity. Given that recent global events have rendered underdeveloped countries more vulnerable to providing consistent electricity to their entire populations, this research suggests solar energy as a resilient electrification solution during crises.","PeriodicalId":46112,"journal":{"name":"Oeconomia Copernicana","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135083031","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}

Purpose of the article: The purpose of this paper is to understand what the factors are that influence green innovation and why there is a big disparity in green innovation capabilities between nations. In addition, this paper aims to investigate the impact of ESG performance of green innovation by using unbalanced panel data covering 118 sample countries during the period of 1999–2019. Methods: Panel fixed effect model; Instrumental variable (IV) method; First-differencing (FD) method; Kinky least-squares (KLS) approach. Findings & value added: ESG performance provides evidence for its positive and significant impact on such innovation. Among the ESG factors, governance seems to have the most important influence on green innovation. Moreover, the positive influence of ESG performance is more evident in higher income and wealthy nations. Furthermore, we also conclude that ESG performance can affect green innovation through FDI, human capital, financial development and trade openness. These conclusions hold up after a number of robustness tests and taking into account any potential endogenous issues.
