In some specific cases it will, but basic game theory shows that the person setting their starting position is more likely to be at a disadvantage in negotiation. Today you can get ranges from 3rd parties (recruiters, former employees, etc)...so it will be the same as today except the starting salary will ALWAYS be a floor from the employer.
