This 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.

This 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.

This study aims to examine the effect of product market competition on a firm’s investments in research and development (R&D) and how this effect varies depending on the firm’s internal corporate governance. This study employs the regression method to analyze the association between product market competition and a firm’s R&D investment. Since product market competition works effectively as an external corporate governance mechanism that reduces agency problems and information asymmetry, this study hypothesizes that a competitive product market promotes R&D investments. Using 11,560 firm-year observations of Korean listed firms for 2001–2020, this study finds a positive association between product market competition and R&D investment. The result also shows this association is more pronounced for firms with weak internal corporate governance mechanisms. Furthermore, additional analysis shows that the effect of product market competition on a firm’s R&D investment is stronger for firms in the low-tech industry. This study provides new insights on the inconclusive association between product market competition and a firm’s R&D investment and practical implications that product market competition drives firms to invest in R&D.

This study aims to investigate the relationship between related party transactions and a firm’s investment in research and development (R&D), as well as the moderating effect of a firm’s financial health on such a relationship. The study applies a fixed-effect panel regression model with a sample of 13,619 Korean listed firms for the period from 2001 to 2020. The results indicate that related party transactions significantly and positively influence a firm’s R&D investment at the 1% level for the study period. Specifically, when related party transactions are divided into operating and non-operating, the results show that only non-operating related party transactions significantly and positively affect firms’ investment in R&D. Moreover, findings report that the effect of related party transactions is stronger for firms with financial distress, lower cash holdings, and in the high-tech industry. The results imply that related party transactions promote a firm’s R&D investment, which is one of the primary business investments that create a firm’s competitive advantage and value. Moreover, the results propose that related party transactions should be carefully evaluated when accessing the firm’s investment behavior.

This 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.

This 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.
