Abstract

Purpose

In response to growing concerns over the negative consequences of Internet addiction on adolescents’ mental health, coupled with conflicting results in this literature stream, this meta-analysis sought to (1) examine the association between Internet addiction and depressive symptoms in adolescents, (2) examine the moderating role of Internet freedom across countries, and (3) examine the mediating role of excessive daytime sleepiness.

Design/methodology/approach

In total, 52 studies were analyzed using robust variance estimation and meta-analytic structural equation modeling.

Findings

There was a significant and moderate association between Internet addiction and depressive symptoms. Furthermore, Internet freedom did not explain heterogeneity in this literature stream before and after controlling for study quality and the percentage of female participants. In support of the displacement hypothesis, this study found that Internet addiction contributes to depressive symptoms through excessive daytime sleepiness (proportion mediated = 17.48%). As the evidence suggests, excessive daytime sleepiness displaces a host of activities beneficial for maintaining mental health. The results were subjected to a battery of robustness checks and the conclusions remain unchanged.

Practical implications

The results underscore the negative consequences of Internet addiction in adolescents. Addressing this issue would involve interventions that promote sleep hygiene and greater offline engagement with peers to alleviate depressive symptoms.

Originality/value

This study utilizes robust meta-analytic techniques to provide the most comprehensive examination of the association between Internet addiction and depressive symptoms in adolescents. The implications intersect with the shared interests of social scientists, health practitioners, and policy makers.

Abstract

Purpose

This study aims to revisit the relationship between Shariah-compliant firms and earnings management. Specifically, the authors examine whether Shariah-certified firms have lower earnings management than non-Shariah-certified firms and how often a firm must hold its certification to observe considerably reduced earnings management. This study also explores how senior management ethnic dualism affects the association of Shariah certification and earnings management.

Design/methodology/approach

The authors analyze the hypothesized association between Shariah certification and earnings management using a panel regression model and several robustness tests, including the Heckman selection model. The sample consists of 547 nonfinancial firms listed on the Bursa Malaysia stock exchange, with 5,478 firm-year observations over the 2001–2016 sample period.

Findings

Shariah certification is found to mitigate earnings management, particularly for firms that consistently retain their Shariah status. The longer firms retain their Shariah certification continually, the lower the earnings management. Additionally, the results indicate that the negative impact of Shariah certification on earnings management is driven by ethnic duality when a specific ethnic group dominates the top management.

Research limitations/implications

Firms’ commitment to religious-based screening and continuation of certification plays a significant role in improving earnings quality. Firms are committed to abiding by the Shariah code of conduct instead of using the Shariah status for reputation purposes to attract investors.

Practical implications

For investors, the continuous compliance status is a crucial indicator of a firm’s commitment to comply with Shariah principles and to mitigate earnings management. Regarding policy implications, Shariah-compliance guidelines can constrain earnings manipulation, especially among firms lacking ethnic diversity.

Originality/value

The study shows that Shariah certification must be maintained consecutively to reduce earnings management. Shariah certification’s governance function is crucial in ethnically homogeneous firms, primarily when one ethnic group dominates the senior management.

Abstract

Purpose

This study aims to investigate the link between audit committee characteristics and the liquidity of initial public offerings (IPOs) in Malaysia, which is an emerging economy in Southeast Asia. Another purpose of this study is to examine the moderating effect of the revised Malaysian code of corporate governance (MCCG) on the link between audit committee characteristics and IPO liquidity.

Design/methodology/approach

The final sample consists of 304 Malaysian IPOs listed in 2002–2017. This study uses ordinary least squares regression method to analyse the data. To confirm this study’s findings, a hierarchical or four-stage regression analysis is used to compare the t-values of the main and moderate regression models.

Findings

The findings show that audit committee characteristics (size and director independence) have a positive and significant relationship with IPO liquidity. Also, the revised MCCG positively moderates the relationship between audit committee characteristics and IPO liquidity.

Research limitations/implications

This study’s findings indicate that companies with higher audit committee independence have a more effective monitoring mechanism that mitigates information asymmetry, thus reducing adverse selection issues during share trading.

Practical implications

Policymakers could use the results of this study in developing policies for IPO liquidity improvements. Additionally, the findings are useful for traders and investors in their investment decision-making. For companies, the findings highlight the crucial role of the audit committee as part of the control system that monitors corporate governance.

Originality/value

To the authors’ knowledge, this work is a pioneering study in the context of a developing country, specifically Malaysia that investigates the impact of audit committee characteristics on IPO liquidity. Previously, the link between corporate governance and IPO liquidity had not been investigated in Malaysia. This study also contributes to the IPO literature by providing empirical evidence regarding the moderating effect of the revised MCCG on the relationship between audit committee characteristics and IPO liquidity.

Abstract

Purpose

The purpose of this paper is to examine the impact of corporate governance strength on stock market liquidity in an emerging country, namely, Malaysia, by constructing a corporate governance score that captures both internal monitoring mechanisms (board of directors’ characteristics, audit committee’s characteristics and internal audit function) and external monitoring mechanism (audit quality).

Design/methodology/approach

The study uses a sample of 2,020 yearly firm observations in Bursa Malaysia over the period 2009-2012. The ordinary least square regression and several estimation methods such as two-stage least squares using instrumental variables (IV-2SLS) and dynamic GMM are employed.

Findings

This study finds a significant positive association between corporate governance effectiveness and stock market liquidity. The finding is robust to alternative liquidity measurements, to alternative estimation methods, and to endogeneity bias.

Research limitations/implications

This result implies that the firms with effective monitoring mechanisms mitigate information asymmetry which leads to less adverse selection problems among traders.

Practical implications

This study provides implications for regulators to help design regulations that enhance stock market liquidity. This study could also help investors and traders to formulate their trading decisions, and enables firms to know the importance of strengthening the corporate governance monitoring mechanisms.

Originality/value

This study constructs a corporate governance effectiveness measure by combining both internal and external monitoring mechanisms. These mechanisms have not been constructed together in one score in the corporate governance literature and the impact of internal audit function, as an internal monitoring mechanism on liquidity, has yet to be examined.

Abstract

Purpose

This study is motivated by the lack of internal audit function (IAF) research and by the call for research on the impact of dominant owners such as family shareholders on audit fees and the demand for audit quality. This study aims to examine the impact of the IAF budget on the selection of industry-specialist auditors and on audit fees, particularly in companies with family-controlled shareholders, a feature unique to Malaysia.

Design/methodology/approach

Data of Malaysian-listed companies during the period 2009-2012 are used. To examine the relationships, logit and ordinary least square regressions are used. Several additional analyses are conducted to assess the robustness of the main results, including alternative measures of specialist auditor and family ownership, endogeneity problems and self-selection bias.

Findings

The results show that the IAF budget is positively related to hiring industry-specialist auditors and audit fees. However, family companies are less likely to support the positive association between IAF costs and engage specialist auditors than non-family companies. In addition, a complementary association between the costs of IAF and audit fees for both family and non-family companies was found. Finally, the results show that there is a negative association between family ownership and the ratio of IAF costs to audit fees, suggesting that family companies rely more upon external auditing than internal auditing.

Originality/value

The contribution of this study is to provide an empirical evidence about the tradeoff between IAF and both industry-specialist auditors and audit fees with considering the moderating impact of family-ownership shareholdings. This issue is yet to be examined, and it provides implications for policymakers and practitioners, as it offers insights into the importance of investing in IAF toward hiring industry-specialist auditors and pricing the audit services.

Abstract

Purpose

This paper aims to examine whether ownership concentration and earnings management affect the stock market liquidity of Malaysian firms.

Design/methodology/approach

This study uses a sample of 2,020 yearly firm observations in Bursa Malaysia over the period 2009-2012. The ordinary least square regression is used to examine the relationships. The study undertakes a sensitivity test by regressing the main study variables by using different measurements. Another robustness test is then used, where a regression based on the change in variables and a one-year lag of the independent variables are used. Furthermore, to alleviate the concern of possible endogeneity, the simultaneity and reverse causality are checked using the lag of the dependent variable, fixed effect regression, two-stage least squares using the instrumental variables and the generalized method of moments using instrumental variables analysis.

Findings

The study finds that firms with a high level of ownership concentration have discrepancies in information between informed and uninformed traders, which impair the stock market liquidity. In addition, this study finds that firms with high earnings management experience greater liquidity. A possible explanation for this is that firms might manage earnings to convey private information to enhance the information content of the earnings. Overall, the evidence suggests that manipulating earnings signals information informatively, particularly in a country with a higher level of ownership concentration and a higher likelihood of expropriating minority shareholders.

Originality/value

This study enriches the limited empirical research devoted to the impact of earnings management and ownership concentration on stock market liquidity especially in the context of emerging economies. The findings of this study are robust to alternative liquidity measurements, to alternative estimation methods, and to endogeneity bias.
