Investigating the effect of corporate governance on audit quality and its impact on investment efficiency

This literature review evaluates empirical studies which concentrate on economic effects on joint audits from an international perspective. We briefly introduce the theoretical and empirical joint audit framework that comprises an adequate structure of the state-of-the-art of empirical research in this field. This is followed by a discussion of the following output factors of joint audits: (1) audit quality; (2) audit costs and (3) audit market concentration. We will summarize the key findings in each area, and provide a description of the analyzed proxies. Finally, we will discuss the current limitations of the studies and give useful recommendations for future empirical research activities in this topic.

Considering that bank does not always perform its functions to overcome financial constraints and to monitor the company’s financial activities, this study aims to examine the role of bank-firm relationships in the effect of internal finance on investment based on the business cycle. The testing stages started with testing the effect of internal finance on investment, testing the role of bank-firm relationships in the effect of internal finance to investment, and testing the role of bank-firm relationships based on the business cycles. Non-financial companies listed on the Indonesia Stock Exchange make the sample of this study, while the data used are the financial statements for the period of 2002 – 2015 sourced from Osiris database. Hypotheses were tested using unbalanced panel regression. The results showed that internal finance has a positive effect on investment. The bank-firm relationships play a significant role in the effect of internal finance on the investment. In the growing companies, bank-firm relationships reduce underinvestment, and in mature companies, bank-firm relationships reduce overinvestment significantly. This study implies that banks run their role in helping to meet the needs of the internal financing. Companies with strong bank-firm relationships reduce the problem of underinvestment and asymmetric information. They also reduce the problem of overinvestment and agency of free cash flow. Banks perform their role in monitoring the financing activities of the mature companies.

This study aims to compare the impact of the ownership structure as one of the essential internal mechanisms of governance on the proxies of external audit quality on a sample of 82 listed Egyptian companies and 77 listed Saudi companies from 2014 to 2021, employing the OLS regression analysis. The current study found mixed results according to the type of ownership and indicators of the external audit quality, both in Egyptian and Saudi companies. The results showed a significant effect of board ownership, management ownership, and family ownership on audit quality. However, the direction of this effect varied between positive or negative in Egyptian or Saudi companies, and the effect was sometimes insignificant. On the contrary, the results showed an insignificant effect of government ownership on audit quality in Egyptian and Saudi companies, or the effect was sometimes significant. The study results may help investors and stakeholders understand the ownership structure’s role as one of the internal governance mechanisms on audit quality. Studies show the effectiveness of governance mechanisms, whether internal or external, according to the institutional environment from one country to another. It also contributes to the use of various indicators to measure the quality of auditing and the quality of financial reports, such as returning the financial statements as an indicator of financial reports and an indicator of audit quality at the same time.
