Is the internal value of the external audit greater for owner-managed businesses than for public interest entities?

The research study by Gad, Litjens en Suijs relates to the question of the Foundation for Auditing Research whether there exists a need for ‘different audits for different purposes’. Does the external audit of a public interest entity require a different approach than the external audit of an owner-managed business? In order to answer this question, it is appropriate to analyze the differences in value of the external audit for a public interest entity versus an owner-managed business.
