    Benefits and Costs of Appointing Joint Audit Engagement Partners
    Practical Implications:

     The results of this study are important to understanding the potential benefits of joint engagement partner audits compared to single-partner audits. The results of this study identify an association between the type of partner audit (joint vs. single) and audit quality and audit fees. As regulators consider the association between joint audits and audit quality, the results of this study suggest there are benefits to joint-partner audits, particularly when the partners are located in the same office. Compared to single-partner audits, joint-partner audits are associated with higher audit quality. Compared to joint audit firms, joint-partner audits appear to provide the same benefits without the increased cost.

    Purpose of the Study:

    Audits using joint engagement partners versus audits using a single engagement partner may produce significant benefits. The purpose of this study is to examine the relationship between joint engagement partners and audit quality and audit fees. The authors of the study predict that joint audit partners improves audit quality via benefits in knowledge and experience, consultation availability with a joint partner, and reducing client-specific knowledge lost due to partner rotation.

    Design/Method/ Approach:

    The authors use 1,345 firm-year observations from the NASDAQ OMX Exchanges in Finland and Sweden for the period 2005 to 2009.

    • The authors find a stronger association between joint engagement partners and higher audit quality when the partners are from the same, rather than a different, office.
    • The authors find that joint engagement partners, compared to single partners, are associated with less accruals (two proxies for audit quality).
    • The authors find a small decrease in audit fees for joint engagement partners from different offices compared to single-partner audits. The authors find no difference in audit quality.
