Different means of earnings management of owner-managed firms versus agent-led firms: evidence from chaebols in Korea
Investment Management and Financial Innovations Volume 13, 2016 Issue #2 (cont. 2) pp. 285-291
Views: 917 Downloads: 307 TO CITEThis paper examines the earnings management behavior of large, family-controlled business groups (so-called ‘chaebol’) in Korea from 2006 to 2010. Specifically, the author studies whether the methods of earnings management are different between chaebol firms versus non-chaebol firms. The author finds no significant difference in accrual-based earnings management by these two types of firms. However, the author shows that chaebol firms’ real-based earnings management is greater than non-chaebol firms, based on their higher abnormal production costs and lower abnormal discretionary expenses, in order to manipulate accounting income upward. The results suggest that owner-managed firms tend to choose real manipulation which negatively affects future corporate performance and consequently mislead investors about the firm value

Integration of enterprise risk management and management control system: based on a case study
Investment Management and Financial Innovations Volume 14, 2017 Issue #1 pp. 19-26
Views: 1996 Downloads: 1971 TO CITE АНОТАЦІЯThis paper aims to discuss the concepts and methodological issues of enterprise risk management (ERM). The case study of company A shows that ERM has been implemented and integrated with management control as a means of monitoring its subsidiaries. First, ERM system was implemented through comprehensive review of corporate risk policies, risk management processes, roles and responsibilities, and risk culture. Second, company A integrated ERM with the existing management control system in order to evaluate the risk underlying the current management activities. Finally, ERM implementation was expanded to all subsidiaries so that each business unit would be delegated for its own risk management. This paper provides insight on the process how group-level internal auditors can use ERM as a tool to manage risk of subsidiaries, thereby filling the gap between academic research and practice. This successful ERM adoption case can be used as a guideline for other organizations, which plan to adopt ERM with reduced costs and improved processes.

The effect of investor sentiment on the means of earnings management
Investment Management and Financial Innovations Volume 15, 2018 Issue #1 pp. 10-17
Views: 1468 Downloads: 504 TO CITE АНОТАЦІЯPrior research has shown that a firm’s tendency to meet or beat earning targets is greater during bad economic times than good times. The paper extends this line of research by investigating which means of earnings management is used in different states of economy. A sample of non-financial companies listed on Korea Securities Market from 2003 to 2011 is used for empirical tests. The findings of this study are summarized as follows. The magnitude of discretionary accruals is negatively related to investment sentiment, indicating that firms tend to use positive discretionary accruals to manipulate reported income upward when the sentiment is pessimistic. However, the real activity based earnings management is not significantly associated with the state of economy. Collectively, this study contributes to behavioral finance and accounting literature by suggesting that managers use discretionary portion of accruals, but do not change their real operating activities, in order to meet or beat earnings targets in economic downturn.

The relation between product market competition and corporate tax avoidance: evidence from Korea
Investment Management and Financial Innovations Volume 16, 2019 Issue #2 pp. 313-325
Views: 1338 Downloads: 211 TO CITE АНОТАЦІЯThis paper examines the effect of industry-wide factors such as product market competition on corporate tax avoidance. Specifically, the focus is on the moderating role of corporate governance in the relationship between product market competition and tax avoidance. To conduct an empirical analysis, a sample of public companies that are listed on the Korea Stock Exchange between 2001 and 2016 is used. The empirical analyses provide the following results. First, product market competition is negatively related to tax avoidance. This suggests that competitive markets act as external corporate governance mechanisms and discipline managers to decrease tax avoidance. Second, the negative association between product market competition and tax avoidance is more pronounced for firms with more independent board of directors and firms with audit committee consisting of outside directors. These findings imply that product market competition acts more effectively when the firm has strong internal governance mechanisms such as board independence and audit committee independence. Therefore, we provide evidence on a complementary relationship between internal governance system and product market competition. The results may be of interest to policy makers and regulators like Korea Fair Trade Commission and Financial Supervisory Service who are involved in promoting market competition, monitoring any abuse of market dominance, and supervising financial reporting quality.

Do labor unions enhance corporate social performance? Evidence from Korean financial markets
Investment Management and Financial Innovations Volume 21, 2024 Issue #1 pp. 289-301
Views: 211 Downloads: 74 TO CITE АНОТАЦІЯThis study examines the impact of labor unionization on corporate social responsibility (CSR) in South Korean listed companies, particularly in the context of chaebol-affiliated firms. Using a dataset of 2,622 firm-year observations between 2005 and 2009, the study employs regression analyses to explore the relationship between unionization and CSR performance. Key findings indicate a significant negative correlation between labor unionization and CSR engagement, suggesting that unionized firms exhibit less involvement in CSR activities. This association, however, is not significant in chaebol-affiliated firms, where the unique corporate structure and shared resources appear to mitigate the influence of labor unions on CSR. Furthermore, the study reveals a positive link between CSR initiatives and labor productivity in unionized firms, indicating that CSR may enhance employee efficiency. The study highlights the intricate relationships between labor unionization, corporate governance, and CSR, particularly in the context of Korean business conglomerates. It emphasizes the importance of aligning labor interests with CSR commitments and underscores the role of effective corporate governance in promoting CSR activities. The positive impact of CSR on labor productivity underscores its potential in boosting employee performance.

The impact of labor unions on corporate tax avoidance: evidence from Korea
Problems and Perspectives in Management Volume 18, 2020 Issue #2 pp. 114-127
Views: 896 Downloads: 173 TO CITE АНОТАЦІЯThis study examines the effect of labor unions on corporate tax avoidance activities. Labor union is an important stakeholder in terms of corporate governance; thus, managers may engage in certain accounting choices that reflect union members’ position to improve the relation with labor union. This paper empirically investigates whether managers engage in tax avoidance activities to secure financial resources for workers’ pay when the negotiation power of labor unions is higher. The empirical analysis is based on a sample of firms listed in the Korean stock market from 2001 to 2008. The authors find that companies, where labor unions are organized, have a significantly higher level of tax avoidance activities. Also, the authors attempt to examine the effect of labor unions’ bargaining power on tax avoidance. While the union membership ratio is not significantly related to tax avoidance, labor unions that belong to upper-level labor organizations significantly affect the increasing tax avoidance activity, on average. Moreover, companies that join an aggressive labor organization (‘Minju’ Federation) show a significantly higher level of tax avoidance activity, compared to those joining a moderate labor organization (‘Hanguk’ Federation). Furthermore, the authors show that such an effect of labor unions on tax avoidance is significant for companies, which are not affiliated with large business groups (‘chaebols’). This result suggests that chaebol group management is not under pressure to negotiate with union members due to higher reputation costs. The findings of this paper offer academic and practical implications that capital market participants need to understand labor unions’ effect on management’s accounting choices.
