In one speech, Cicero mentions "shares that had a really high value at the time." Such proof, in Malmendier's read, suggests the instruments were tradable, with unsteady values supported associate organization's success. The societas declined into obscurity within the time of the emperors, as most of their services were appropriated by direct agents of the state.
