Audit Quality and Equity Capital Costs of Manufacturing Companies Listed on the Indonesia Stock Exchange

Introduction

In the business world, especially in the manufacturing sector listed on the Indonesia Stock Exchange, audit quality plays a crucial role in determining the cost of equity capital of a company. Audit quality can be measured through several indicators, including the size of the audit firm, the specialization of the audit industry, and the term of office of the auditor. This study aims to investigate and analyze the relationship between the three variables and the cost of equity capital.

Background and Literature Review

The importance of audit quality in the manufacturing sector listed on the Indonesia Stock Exchange cannot be overstated. Audit quality is a critical factor in determining the cost of equity capital of a company. A high-quality audit can increase investor confidence in the company's financial statements, leading to better investment decisions. On the other hand, a low-quality audit can lead to a decrease in investor confidence, resulting in a higher cost of equity capital.

Several studies have investigated the relationship between audit quality and the cost of equity capital. For example, a study by [1] found that audit quality has a significant impact on the cost of equity capital of companies listed on the Indonesia Stock Exchange. Another study by [2] found that the size of the audit firm, the specialization of the audit industry, and the term of office of the auditor are all significant factors in determining the cost of equity capital.

Methodology

This study uses secondary data collected from the analysis of the sample company's financial statements and data from the Indonesian Capital Market Directory (ICMD). The data analysis process uses SPSS statistics software version 18.00. The proposed hypothesis is that the size of the audit firm, the specialization of the audit industry, and the term of office of the auditor have a significant relationship with the cost of equity capital.

Results

The results of the data processing process show that in the partial significant test, the size of the audit firm and the specialization of the audit industry have a negative relationship with the cost of equity capital, but it is not significant. Meanwhile, the term of office of the auditor has a positive relationship with the cost of equity capital, but is also not significant. However, the results for simultaneous tests show that the size of the audit firm, the specialization of the audit industry, and the term of office of the auditor have a significant relationship with the cost of equity capital.

Additional Analysis and Explanation

Good audit quality is expected to increase investor confidence in the company's financial statements, so as to influence their investment decisions. Larger audit firm size is usually associated with higher credibility, because large firms tend to have more resources and experiences. However, in this study, although the size of the audit firm shows a negative relationship with the cost of equity capital, this does not achieve statistical significance.

Specialization of the auditor industry also has the potential to affect audit quality. Auditors who have specialization in certain industries usually understand the characteristics and risks faced by companies in the sector. However, the results of the study showed that this specialization had no significant influence on the cost of equity capital.

The term of office of the auditor, on the other hand, illustrates the duration of an audit firm auditing the financial statements of a company. The positive relationship found between the term of office of the auditor and the cost of equity capital shows that the longer the auditor audits the company, the more likely they can produce more transparent and reliable reports. However, the absence of significance may be caused by other factors that also influence the cost of equity capital that is not captured in this study.

Conclusion

Overall, this research provides an important insight into the relationship between audit quality and equity capital costs in the manufacturing company sector listed on the Indonesia Stock Exchange. Although some variables show an insignificant relationship, it is important for companies to continue to pay attention to audit quality as part of the company value increase strategy. Further research and deeper analysis are needed to understand the factors that can affect this relationship more comprehensively.

Recommendations

Based on the findings of this study, the following recommendations are made:

Companies should continue to pay attention to audit quality as part of the company value increase strategy.
Further research and deeper analysis are needed to understand the factors that can affect the relationship between audit quality and equity capital costs.
The Indonesian Capital Market Directory (ICMD) should continue to provide data and information on the audit quality of companies listed on the Indonesia Stock Exchange.

Limitations

This study has several limitations that should be noted. Firstly, the study only focuses on the manufacturing sector listed on the Indonesia Stock Exchange, and therefore the findings may not be generalizable to other sectors. Secondly, the study only uses secondary data, and therefore the findings may be subject to limitations of the data. Finally, the study only investigates the relationship between audit quality and equity capital costs, and therefore the findings may not be comprehensive.

Future Research Directions

Future research should aim to investigate the relationship between audit quality and equity capital costs in other sectors, such as the service sector or the financial sector. Additionally, future research should aim to investigate the impact of other factors, such as corporate governance and financial reporting quality, on the relationship between audit quality and equity capital costs.
