A study of a major East Coast business law firm with offices in severa
l cities in the United States provides a look at how the legal profess
ion regulates itself. By using different methods (statistical measures
, prominence scores, informal surveys of control systems) to examine s
eparately the procedures (control routines, Chinese wall, self-disqual
ification) for settling conflicts of interest, several limits are brou
ght to light. Thought is given to ways of regulating markets through i
nstituted regulators and through actors themselves.
