Purpose This paper aims to investigate whether the choice for a Big4-affiliated local audit firm affects the capital structure of listed companies in Indonesia, a fast-growing emerging country that is characterized by high information asymmetry and low litigation risk. A unique characteristic of the Indonesian audit environment is that Big4 auditors can only enter the market indirectly through affiliation with a local audit firm. Design/methodology/approach A sample of Indonesian listed companies between 2008 and 2015 is used to investigate this relation using ordinary least squares (OLS). To address the concern that the choice for Big4-affiliated auditors might reflect client characteristics, the authors also perform OLS on a matched sample, using both propensity-score and entropy-balance matching. Findings Across all three samples, the authors document that companies audited by a Big4-affiliated local audit firm display lower debt ratios. The authors find no such effect for affiliation with second-tier audit firms. Surprisingly, they find that the negative effect of Big4 affiliation is increasing in client size. Research limitations/implications This study provides evidence of the consequences of hiring Big4 auditors on the perceived information asymmetry by financial markets under extreme conditions: in an environment characterized by low litigation risk and where Big4 auditors can operate only indirectly through affiliation. Practical implications The results of this study are of interest to policymakers, managers and financial stakeholders in emerging countries where external financing is important yet difficult to obtain because of severe information asymmetry. Hiring a Big4 auditor, even only through affiliation, might reduce perceived information asymmetry and increase the access to external equity financing. Originality/value To the best of the authors’ knowledge, this study is the first to provide evidence of the effect of Big4 auditors on their clients’ capital structure when they can operate only indirectly through affiliation with a local auditor.

This paper documents that in Indonesia, where litigation risk is low and foreign audit firms can only enter the market through affiliation with a local audit firm, the appointment of a local audit firm affiliated either with a Big4 or a second‐tier audit firm reduces the cost of debt for listed companies significantly. This finding holds irrespective of the risk profile of the client and is independent of whether or not we control for endogenous auditor choice. There is less conclusive evidence of a difference in the magnitude of the effect of Big4 affiliation versus affiliation with a second‐tier audit firm. Our evidence is in line with the idea that Big4 and second‐tier audit firms are perceived as applying uniform quality criteria around the world, regardless of the local circumstances in which they operate.
