  text: We examine the relation between voluntary audit and the cost of debt in private
    firms. We use a sample of 7420 small private firms operating in the period 2006-2022
    that are not subject to mandatory audits. Firms self-select into voluntary audits
    because of the economic setting (e.g., ownership complexity, export, subsidiary
    status) or because firm fundamentals limit their access to financial debt. In
    the outcome analyses, we find that voluntary audits result in higher, rather than
    lower, interest rates with increases ranging from approximately 1.7 percentage
    points, but going higher depending on the exact specification. This effect is
    present regardless of the perceived audit quality (Big-4 vs. non-Big-4), consistent
    across auditor types. Audited firms’ earnings are less informative about future
    operating performance. Voluntary audits facilitate access to financial debt for
    high-risk firms. The price paid is reflected in higher interest rates for voluntary
    audits – firms with higher information/fundamental risk.
