When a "Friendly" Board Is a Feature, Not a Flaw
After Sarbanes-Oxley, firms met new independence rules with directors tied to the CEO, and it did not cost them.
Regulation is a blunt instrument. The Sarbanes-Oxley Act pushed all public firms toward more independent boards, but the cost of that extra outside monitoring varies enormously across firms. How do firms adapt when a one-size rule does not fit?
The study documents a subtle response. After the law passed, firms replaced insiders with outside directors who had social or professional connections to their CEOs. The substitution was most pronounced exactly where outside monitoring is most expensive, at small, young firms outside the S&P 1500 with little analyst scrutiny.
Crucially, adding these friendly directors did not reduce firm performance. That pattern is consistent with the substitution being an efficient way to absorb the monitoring costs the new rules imposed, rather than a story about entrenchment.
The broader lesson is that board composition is an equilibrium outcome. The same feature that looks like weak governance at one firm can be a sensible adaptation at another.
The Takeaway
Friendly directors were an efficient answer to Sarbanes-Oxley, concentrated where monitoring is costliest and carrying no performance penalty.
