The use of internal control systems and codes of conduct as anti-corruption practices: evidence from Vietnamese firms

Abstract

PurposeDrawing from fraud triangle theory, the purpose of this paper is to examine whether the use of internal control systems and codes of conduct, as a specific element of internal control, helps firms to reduce law violations and bribery payments to public officials.Design/methodology/approachThe study is based on survey data of Vietnamese firms, conducted between September and December 2018. The authors run logistic and ordinary least squares regressions to test the hypotheses.FindingsThe study showed that the use of internal control systems has a negative and significant relationship with law violation but not with bribes paid to public officials. By contrast, the use of codes of conduct appears to reduce bribe payments but not law violations.Research limitations/implicationsCross-sectional data do not allow us to confirm causal relationships. The self-reported measures of the use of codes of conduct and internal control systems may suffer from social desirability biases and should be further validated with different samples of firms. Finally, the relatively modest number of firms that participated in the survey raises a concern of sample representativeness.Practical implicationsFor businesses, the application of codes of conduct and internal control systems enhances the reliability and certainty of the firm's operations as well as its integrity, contributing to the firm's long-term development. For policymakers, encouraging businesses to use internal control systems and codes of conduct would contribute meaningfully to the anti-corruption effort.Originality/valueBusinesses in emerging economies face a dilemma of how to participate in an anti-corruption agenda while staying profitable. This study shows that the use of internal control systems and codes of conduct would serve both purposes, contributing to businesses' sustainable development.

The impact of internal control systems on the intensity of innovation and organizational performance of public sector organizations in Vietnam: the moderating role of transformational leadership

“…According to IST, while transformational leaders recognize the critical role of ICSs in the innovation process, they seek to leverage the ICS effectively to promote innovation by developing strategies for innovation that are compatible with the ICS's actors, namely, followers. For instance, they frequently demonstrate their commitment to innovation by implementing appropriate internal control strategies, which include paying close attention to the internal control structure and procedures, addressing internal control deficiencies, enhancing knowledge mining, and other similar endeavors (Le et al, 2020;Shen et al, 2020).…”

“…People, including the policies and forms contained within, affect internal control. Therefore, internal control can only offer a reasonable level of certainty and not complete assurance (Le et al, 2021).…”

Internal Control Systems and Performance of Emerging Market Firms: The Moderating Roles of Leadership Consistency and Quality

“…The research subjects are businesses located in Vietnam, which is a developing market. Vietnam is a crucial setting for investigating this topic because most companies in the country are young, and internal control applications have only recently been promoted (Le et al, 2021). This study used a purposive convenience sampling strategy to recruit relevant respondents by screening for their work positions and experience.…”

“…As a result, these firms are under pressure to leverage their internal control system, which is an essential pillar of corporate governance (Aziz, 2013). As a result of this challenge, interest in the various roles of internal control systems in business operations is growing in the emerging market context, including preventing law violation (Le et al, 2021), promoting innovation capability (Chan et al, 2021; Li et al, 2019), and lowering equity capital and agency costs (Khlif et al, 2019; Zhang et al, 2022). In this context, many recent studies have been conducted to explore the internal and external factors that are related to the effectiveness of internal control, including corporate culture (Shu et al, 2018), the characteristics of audit and market competition (Kim & Kim, 2017), and the separation of the roles of the board chair and chief executive officer (CEO) (Abernethy et al, 2019).…”
